As the beef industry continues to innovate, so do the ways of doing business. Social media has changed how every company markets and brands themselves, as well as public figures, artists and athletes. In our business, it should be no different.

Here are a few ways that social media will help your cattle operation:

1 - Peer RecommendationIf our friend has it, we have

to have it too, right? In most cases, the answer

MARKETING by Lauren CHASE

Six Reasons SocialMedia Will Help Your Operation

is “yes”. What social media has created is a space for your friends, family and acquaintances to share how they feel about all sorts of things even if they enjoyed your bull sale. If a rancher down the road posts on Facebook that he bought a good bull from XYZ Ranch, I’m more inclined to check out the bulls at that ranch because I trust my friend’s opinion. And thus begins the word-of-mouth, free advertisement for XYZ Ranch.

2- Beef Business OnlineToday, there are so many ways for

a person to contact another person. If I want to reach a friend, I could call, text, tweet, Facebook message, email, instant message, SnapChat, Instagram them, etc. As chaotic as this sounds, the upcoming generations of beef producers will conduct business through a variety of these forms, and because social media allows for instant contact and an easy way to share visuals, it becomes another way to

My grandfather was a corn farmer and raised cattle in Iowa for the majority of his life. Now that he is retired, he and his fellow farming buddies head to the local coffee shop at least once a week to brag about grandkids and analyze what’s happening in society. While this type of gathering is still

useful and enjoyable, the younger generations are finding other ways to communicate with each other and to market their cattle.

Opportunities abound to share your operation’s story in today’s world of

Facebook and Twitter.


MARKETINGconduct business.

Are you trying to get people to your bull sale? Post photos of the bulls on Twitter, Facebook and Instagram. Potential buyers are out there and could message you for more details. Are you trying to make people aware of a legislative issue affecting cattle producers? Post the link to your sites and spread the word. Are you trying to communicate with members in a committee? Develop a group forum on Facebook to keep everyone up to date.

3- Telling the Beef StoryNot only can social media be

used to do business, but it is a great way to reach networks of people outside of the beef industry and teach them about agriculture. You become a spokesperson and a face for beef, essentially “humanizing” the industry and making it relatable to the consumer.

Also, the photo of the bull you posted may be geared towards buyers, but it could also catch the eye of your wife’s cousin in New York City who doesn’t know how his steak is produced. Maybe the photo makes him think: “Hmm, I wonder why the bulls are sold like that,” and then messages you to learn more about your sale. Advocacy is a collective effort and the more we can

reinforce the beef lifestyle through imagery and social media, the better we can tell the beef story.

4 - Other AdvantagesSocial media is free and it is

relatively easy to produce content. If you have a smartphone, you’re golden. Cross-promotion of content on major social media sites is also easy and will only increase your marketing.

5 - TipsCarefully consider your

content and be ready to engage in conversation if people comment. Reciprocity is key --- when you go from being a “talking head” to allowing your customers to have a voice, your interaction will greatly increase.

Watch trends and be willing to try new things. Hashtags are huge on Twitter and have become more frequent on Instagram and Facebook. For those who don’t know, hashtags are like “key words” and can help you engage in the conservations you want to be in. For example: #ranchlife #beef #Texas

6 - @GoBrangusThe IBBA has done a terrific job

of establishing itself on social media sites like Facebook and Twitter.

ABOUT THE AUTHOR:Lauren Chase graduated from the University

of Iowa with degrees in journalism and anthropology. She now works as the multimedia outreach specialist for the Montana Stockgrowers Association, working to tell the story of Montana family ranching.

Lauren can be contacted by email at [email protected] or through twitter at @LaurenMSea.

As a Brangus producer, utilize the services they have provided for you. For example: If you are out checking cows and snap a photo of a new calf, tweet it and include a mention to the IBBA (@gobrangus). Most likely, you will be retweeted by them. What does all of this mean? Not only will your photo go out to your followers, but once it’s retweeted, it will go out to all of IBBA’s followers. People who follow IBBA on Twitter, most likely have some interest in Brangus cattle. One of those followers could be a potential buyer for you. It’s a win-win!

Understanding these trends and new marketing techniques is essential for the beef industry in the upcoming decades. Even though our businesses may look different than how our grandparents ran it, we all still share the same passion for the beef industry and want our operations to be successful for our own grandchildren!

The Little Details on a Cattle Operation

Avoid the Weak LinkThe commonly quoted saying

that a chain is only as strong as its weakest link has relevance for cattle operations. A producer can do many things right in a process and still not achieve the desired result. This happens because one or more critical aspects are overlooked or not managed properly.

Take animal health program planning and administration, for example. A producer can design an appropriate vaccination program, acquire vaccines and supplies from a reputable supplier, place vaccines in refrigerated storage as directed by product labels, and then administer the vaccines to the target animals with the end result being that the desired immune response in the vaccinated cattle is not obtained if there is a weak link in this chain of events.

Where could these weak links occur to make this process a waste of time and money? Here are some possibilities:1. Vaccine was stored improperly

before getting to the user.2. The “refrigerated” storage that

the cattle producer used was not within the appropriate temperature range (e.g., the old

farm refrigerator did not keep it cold enough).

3. The vaccine was not administered at the appropriate time to the cattle.

4. Modified-live vaccine was placed in a syringe containing chemical residue from cleaning agents that rendered it ineffective.

5. Modified-live vaccine components were mixed, and then the leftover mixture was saved later use. Once mixed, these products need to be used within a few hours.

6. The vaccination administration technique was incorrect (e.g., the needle was pointed upward when the vaccine was released from syringe causing the product to leak excessively from the administration site).

7. The dosage was incorrect, or a booster shot was missed.

A case in point of this type of weak link actually occurring is documented in a recent University of Idaho study. Only one-third of beef cattle producers’ and animal health product retailers’ refrigerators were deemed acceptable for animal health product storage. The majority of their refrigerators did not adequately maintain the

recommended temperature range for animal health product storage. Exposure to temperatures outside of the recommended range can affect the efficacy (effectiveness) of animal health products such as vaccines. In fact, it has been suggested that the leading cause of immune response failure is improper vaccine storage. So, not only were the animal health products stored by the producers whose refrigerators did not function as needed potentially compromised, but it is also plausible that some of the producers with properly functioning refrigerators could have purchased vaccine from retailers with malfunctioning refrigerated storage units and also experience product effectiveness problems.

Critical Control PointsPersons involved in the meat

processing industry are likely familiar with the HACCP (Hazard Analysis and Critical Control Points) concept. It is a management system to address food safety through the analysis and control of various hazards at all stages of production, distribution, and other processes to the point of consumption. In essence, HACCP is a preventative system to control hazards in foods.

Little Things Matter. Most producers would assert that they do a pretty good job of managing their cattle operations. They implement many recommended production practices. Yet, beyond this, care must be taken to ensure that these efforts get the results that they are intended realize. This means not only doing

the right thing, but also doing it the right way. Taking care to get the little implementation details done well can make a noticeable difference in production outcomes.


It involves hazard analysis, critical control point identification, and establishment of critical limits, monitoring procedures, corrective actions, verification procedures, and documentation procedures.

Critical control points are steps where control measures are needed to achieve the desired outcome. In the case of meat processing, a desired outcome may be food safety; whereas, a desired outcome in a cattle operation might be a particular rate of reproductive efficiency or average daily gain.

There are many important critical control points on cattle operations. A review of financial, economic, and biological data from domestic cow-calf producers in the late 1990’s revealed a particularly crucial critical control point that is likely still very relevant today. Feed cost was determined to be responsible for over half of the herd-to-herd variation in profit. Thus, it was deemed to be a “critical” control point for improving herd profitability. This suggests that if cattle operation managers do all the little things right when it comes to managing feed cost, then they will take control of profitability in large part. By identifying and controlling other key control points, producers can also improve their chances of realizing desired production or financial outcomes.

Assess and ActSo how do cattle producers put

these concepts into practice? A logical place to start is by developing a farm-level procedure similar to HACCP. A self-audit of the beef cattle operation is one way to

FEATUREbegin this self-monitoring exercise. Start by developing a thorough review checklist or set of questions for important processes on the operation. Then go through and answer these questions for the operation. From this self-audit, farm managers can determine where improvements or better controls are needed. Corrective actions must then be followed through with and then reviewed once again to determine future adjustments needed to continue fine-tuning production processes.

There are some existing self-assessments available that apply specifically to cattle operations. The Beef Quality Assurance program offers free cow-calf and stocker self-assessment booklets online to help producers benchmark their operations: http://www.bqa.org/assessments.aspx. Producers may also want to develop their own assessment tools tailored to their specific resources, circumstances, and goals. Another useful approach is to ask someone from outside the operation to assist in reviewing it. This helps provide a fresh set of ideas to be tapped that might not come to light from people engrained in the operation themselves.

To be effective over the long-term, producers must not view this approach as a one-time event that permanently “fixes” all of the inefficiencies or ineffective aspects of the operation. It must be done from time to time on a continuous basis to maintain and advance production efficiency and effectiveness. If producers do not continue to closely monitor and manage the various production processes, then they

risk lapsing into wasteful or useless decisions that ultimately take away from productivity and profit.

Cattle operations could take a page from the playbook of industrial manufacturers. Just ask a manufacturer about what lean manufacturing can do to improve an operation. This approach can work for cattle operations, too. There are plenty of books and other references on lean manufacturing to learn more about it. Try searching online for “lean”, “six sigma”, “continuous improvement”, or “kaizen”.

The cost of purchasing a bull may seem high at a glance; however, that expense becomes relatively small when it is spread across your bull’s calf crop for a three- to five-year period. Example 1 shows how you can turn an expense into a savings. Bull procurement decisions can greatly impact your future calf crops and herd genetics for many years. When you consider that the bull contributes one-half of the genetic makeup of your calf crop and may sire 25 to 40 or more calves per year, it is easy to see that he is the most

Bull Buyer’s Guide

Never underestimate the power of your bull. Selecting and purchasing a bull for your beef herd could be considered one of the most important decisions you make in your operation. Don’t make a quick, unprepared decision on purchasing a bull. Never consider purchasing a bull without a proven record and a sound

genetic background. Using a bull with poor performance and a weak genetic base could delay improvements in your herd for several years. The small expense you have in purchasing a bull is the difference between the purchase price of the new bull and the salvage value of the old bull (see Example 1). This investment will add efficiency and profitability to your herd for years to come.

Example 1. Cost of a bull purchase $3000 Purchase Price of New Bull - 2090 Salvage Value of Old Bull (1900 lbs. X 1.10/lb.) $ 910 Net Cost of New Bull

If the new bull sires 90 calves over the next 3-5 years, $910 ÷ 90 = $10.11 cost/calf. If the bull sires 90 calves that are 10 pounds heavier at weaning and they sell for $1.09/lb. (3-year average for 500-pound calves – GA Auction Markets, 2009-2011) at weaning, you will have paid for the bull.


FEATUREimportant individual in the herd. Keep in mind that a bull that will improve a herd must have genetic superiority over both the cows in the herd and over pervious bulls.

The best way to remain efficient in today’s beef industry is continue to produce more pounds of product per cow exposed. That task can become hard to achieve without the help of a superior bull. Fortunately, weight at various ages is heritable. Birth weight and weaning weight are estimated to be about 30 percent heritable, while yearling weight is about 45 percent heritable. This means that a certain degree of birth weight, weaning weight and yearling weight is inherited from the parents and that progress can be made by selecting for these traits.

SELECTION TOOLSBirth, weaning and yearling

weights are normally used to evaluate breeding animals. Actual or adjusted weights may help in making

comparisons between bulls in the same contemporary group (a group of animals from the same herd, year and season that is raised together under the same conditions). Since environmental factors like feed and weather affect weights, actual or adjusted weight can be misleading if bulls come from different contemporary groups. Within a herd, weight ratios help account for some of the environmental differences between contemporary groups. But, ratios can also be misleading if bulls come from different herds. Expected Progeny Differences (EPDs), on the other hand, are calculated across herds. A bull’s EPD for a trait is a more accurate estimate of his genetic worth than his weight, adjusted weight or ratio. EPDs not only account for contemporary group and herd differences, they also include information on a bull’s relatives as well as his individual performance. Breed associations report EPDs on weights and many

other traits.Most major breed associations

have National Cattle Evaluation programs. Breeders who are involved in their breed’s performance program should have birth, weaning and yearling weight EPDs available on yearling bulls. In all of these breeds, weight EPDs are expressed in pounds of calf. For example, if bull A has a weaning weight EPD of +45 and bull B has a weaning weight EPD of+35, the calves produced by bull A are expected to weigh, on the average, 10 pounds more at weaning than those of bull B, assuming the bulls are bred to comparable cows.

Advances in National Cattle Evaluation have made estimating a bull’s genetic worth more accurate than ever before. EPDs allow valid comparisons of all bulls of the same breed, but they do not allow comparison of bulls from different breeds. Since breeds have different average performance, base years

(continued on page 14)


FEATURE(continued from page 13)and evaluation procedures, direct comparison of EPDs from different breeds can be extremely misleading. It should also be noted that a bull with an EPD of zero is rarely average. In most breeds, zero is the average of some base group of animals. Since breeds change over time, in some breeds it is possible to find bulls with positive weaning and yearling weight EPDs that are several pounds below the average of all yearling bulls in that breed. Current breed averages and information on how to use EPDs are included in breed association sire summaries, which are available on most major breed association websites.

Accuracy Values (ACC) are usually published with EPDs. The accuracy values indicate the reliability of the EPD, or how likely the EPD is to change as more information becomes available. Accuracies are usually expressed as correlations ranging from zero to one. The

closer the accuracy is to one, the more reliable the EPD is. Yearling bulls normally have low accuracy values. Older AI sires can have very high accuracies.

RECOMMENDED PERFORMANCE STANDARDS

Weaning Weight- Yearling WeightCommercial producers are paid for

pounds of calf. Two very important traits to consider are weaning and yearling weights. However, single trait selection may result in problems with other traits. A good example is selecting for yearling weight alone, which results in increased birth weight because the two traits are genetically correlated. Select bulls that have an excellent combination of performance EPDs that are at or near the bulls’ breed average. Desired genetic improvement involves a combination of several traits, including weaning and yearling weights.

Milk ProductionMaternal ability within a breed can

best be evaluated with milk EPDs; however, milk is not measured directly in beef cattle performance programs. It is measured in terms of how it affects weaning weight. Milk EPD on a bull is an estimate of pounds of calf at weaning produced by the bull’s daughter due to her milking ability. For example, if bull A has a milk EPD of +5 and bull B has a milk EPD of +2, all other things being equal, bull A’s daughters should produce calves that wean 3 pounds heavier than those from daughters of bull B due to extra milk production. There is some variation in the terminology used by different breed associations in reporting maternal EPDs. An explanation of maternal EPDs is included in a breed’s sire summary.

Producing extra milk requires that a cow consumes extra protein and energy. High milk production can affect a cow’s ability to breed back after calving. For this reason, selecting for maximum milk production is not a good idea in most commercial herds.

ConformationThe cattle industry produces cattle

of all breeds, sizes, ages and quality. There is a market for all of them. However, if you sell feeder calves or feed out your own cattle, consider the following points:•Good quality cattle eat no more

feed than low quality cattle and are just as efficient at converting feed to beef.

•Bulls should generally have a muscling score of one and be


FEATUREmedium plus to large minus framed, according to the USDA feeder calf standards (Table 1). Such calves will bring a higher price than lower grade calves.

• Low quality cattle with poor conformation usually are more subject to price declines in years of over production than are high quality cattle. Small framed cattle mature early and are slow, inefficient gainers if fed past maturity.

Frame ScoreHip height in inches is used to

give an indication of frame size. Most bull test stations and a large percentage of purebred breeders will have a yearling hip height for each animal. Table 1 gives the ranges of hip height as they relate to mature frame size. Remember, taller cattle do not necessarily grow faster or more efficiently, but they do have a later maturity pattern. Small-framed cattle are discounted in Georgia markets. A bull needs to have enough frame to produce calves that are at least USDA Medium.

Birth WeightFirst calf heifers have the most

calving problems, so buying a bull

with a low birth weight EPD is extremely important when the bull is to be used on heifers. Birth weight is the single most important trait that influences calving difficulty. While many cattlemen look at actual birth weights on bulls, birth weight EPDs are the most accurate measure of a bull’s potential calving ease.

Many breeds report Calving Ease EPDs that are calculated using birth weight and calving scores. These can also be helpful in selecting bulls. Refer to the breed association’s sire summary for a description of how these are reported for a particular breed.

Scrotal CircumferenceResearch indicates that yearling

bulls with large testicles sire daughters that show estrus at an earlier age than bulls with smaller testicles. Be sure the bull you select has a scrotal circumference that is at least 30 cm at 1 year of age.

Physical and Semen EvaluationIf the bull you are considering

buying is 12 months or older ask for a physical and semen examination. This can be done by the local veterinarian and will increase your confidence that the bull will be able

to settle cows.

Other TraitsBreed associations report EPDs

for many other traits and this large volume of information can be overwhelming to the bull buyer, so focus on the basics listed above. You do not have to understand every aspect to be able to select a good commercial bull. When you become comfortable with the basics, consult the breed association website for updates on the most recent developments.

HOW MUCH “BULL-POWER” DO I NEED?

Several factors can help determine the number of cows that can be bred to one bull.

AgeThe number of cows per bull will

vary with the bull’s age, condition and libido. Use an adequate number of bulls with good libidos. Bulls should be in good body condition, but not fat, at the beginning of the breeding season. Young, growing bulls may require extra feed during the breeding season to meet their protein and energy needs. A yearling

FEATURE(continued from page 15)bull should not be expected to breed more than 20 to 25 cows, while a mature bull with large testicles, good semen and good libido can breed 25 to 40 or more cows.

ConditionYou cannot expect fat or thin bulls

to perform up to the standards of properly conditioned bulls. Poor nutrition can influence semen quality. Fat bulls lack the stamina to breed enough cows.

Length of Breeding SeasonLength of the calving season and

number of calves born during each 21 day period of the calving season does have some influence on the number of cows that can be bred to one bull. Mature bulls can breed up to 40 cows during a 60- to 90-day breeding period and sire a high percentage of these calves in the first 40 days of the calving season. If cows are run in large groups, two

bulls that are the same age and breed could run with 80 cows.

Breeding SystemsAn artificial insemination (AI)

program will not require as many bulls, but the quality of the bulls turned out after the AI period needs to be very high to ensure against poorer quality calves than the AI sired calves. Have a short AI program, no longer than 40 days, and then turn out the cleanup bulls.

OTHER FACTORS TO CONSIDER WHEN BUYING A BULL

The bull you buy should be functionally sound -- a good breeder with a long life ahead -- and he should be structurally correct, with sound feet and legs and strong pasterns.

The bull should not have swollen joints and should be able to move freely and easily.

The bull should not be extremely nervous. A bull with a mean

disposition is difficult to handle and he may pass on his nervousness to his offspring.

Be sure you do not buy disease when you buy a bull. Request a copy of the bull’s health record. Place new bulls in an isolation paddock where you can observe them for 30 days before putting them with the herd.

WHERE TO BUY A BULLMany top cattlemen think where

to buy a bull is the most important choice involved in their purchase. You need to know that records of birth dates, rate of gain, weaning weights and health conditions of a bull are just as the seller says. You need to know that the breeder will live up to his responsibilities. It has been said that records and pedigrees are as good or as poor as the integrity of the breeder. Here are some recommendations:•Buy from a breeder whose

integrity is above reproach.•Buy from someone who has

complete performance records on his cattle, and knows what those records mean.

•Buy from a place where you know the type of management under which the bulls were produced.

•Buy bulls from central test stations where all records are available.

•Buy bulls from performance oriented producer sales.

•Buy bulls from breed association sponsored sales.

USING ARTIFICIAL INSEMINATION

Artificial insemination increases your chances of promoting the important traits. Since many of


FEATUREthe bulls in the AI studs have a great number of progeny with performance records, you can predict more accurately what their calves’ performances will be in your herd. AI services also screen their bulls closely for any undesirable traits.

Whether you breed your cows by AI or not is a decision you must make based on your own labor and management situation. However, you can consider AI as one method of “buying a bull:’

SELECTING A BULL FOR CROSSBREEDING

It is just as important to select bulls for a crossbreeding program based on traits that are heritable as

it is for other breeding systems. You can improve your herd by careful selection and produce hybrid vigor at the same time.

DETERMINING A BULL’S WORTH

It is very difficult to predict the dollar value of a particular bull; however, the following factors can affect a bull’s value:•The number of calves the bull

may sire.•The performance level of the

herd on which the bull is to be used. Almost any good bull will improve the performance of a poor herd, while only very superior bulls can help a high performing herd.

•The type of breeding system you select. Purebred breeders can usually justify a higher bull investment than can commercial producers.

SUMMARYSelecting and buying a herd bull

is the quickest way to make genetic improvement in your herd. The selection process must include looking for those traits that are economically important and highly heritable. Your own herd records are necessary if you are to select a bull that will improve your genetic base. Demand and buy bulls with total performance that will improve your herd.

Research has shown that increasing cow size can increase weaning weight. That sounds simple enough, but the economic viability and physiological consequences must be considered when choosing cattle based solely upon mature size. Research conducted at Oklahoma State University in 2011 indicates that to increase calf weaning weight a mere six pounds in a crossbred cowherd, you must increase cow body weight 100 pounds! That means a 1,400-pound cow will only wean a calf 12 pounds heavier than a 1,200-pound cow based on cow body weight alone. Cow dry matter intake increases as weight increases, meaning you would have to reduce

stocking rates to maintain a larger cow.

Data returned from some of the pioneering research in cow efficiency has shown that accepting moderate weaning weights from a more efficient cow is more profitable than trying to maximize weaning weight. Bob Kropp, PhD, (Oklahoma State University, 1971) demonstrated that increasing a dam’s milk did in fact increase calf weaning weight and dollars per calf but decreased total profit due to increased forage and supplement intake.

When comparing cows at three different levels of milk production, a University of Nebraska, Lincoln study conducted by Lewis found

“We are going to be your dam tour guide. Does anybody have any

dam questions about dam milk?”

that cows with increased milk production weaned heavier calves. However, as level of milk increased, it took more milk per pound of additional calf weaning weight (or a greater milk to gain ratio) resulting in a less efficient conversion of dam’s milk to calf weaning weight. At low levels of milk production, each additional pound of calf weaning weight required 11.8 pounds of milk. In contrast, high levels of milk production required 52.6 pounds of milk for each additional pound of calf weaning weight. Several other institutions have conducted similar studies with the results being strikingly similar with average milk use efficiencies of these studies being

Beef Cow Efficiency

What if we told you that you could improve your profit potential by decreasing your calf weaning weights? Throughout the course of the last half-century, cattle producers have predominately adopted a theory of maximizing production outputs to maximize profit. However, during that same period,

input costs have continued to rapidly rise with no sign of slowing down. As milk production, weaning weights and cow size in the cattle industry continue to climb, you may need to consider the hidden costs of increased production before making your bull buying decisions this fall.


FEATURE42.6 and 20 for high and low milking cows, respectively. There is no doubt that increasing milk production in a cowherd can improve weaning weights. However, this research indicates that increasing milk production as a means to increase calf weaning weight is clearly an example of diminishing returns and economic viability is paramount when considering the increased inputs required to increase milk production.

As milk production in a cow herd increases, so do the requirements of those cows. Research done at Oklahoma State University in 2003 shows that for every one-pound increase in milk production of a cow, her dry matter intake is increased by 0.33 pounds. Using our averaged milk use efficiency values of 42.6 and 20 pounds along with the increase in cow dry matter intake per pound of milk, a feed conversion of cow intake to calf weaning weight ratio can be calculated. High milking cows require an additional 14 pounds of forage intake to yield a single additional pound of calf weaning weight due to milk production. In contrast, cows producing lower levels of milk only require an added 6.6 pounds of forage intake per pound of additional calf weaning weight due to milk production. There are not many scenarios where

a feed conversion of 14 pounds of feed per pound of gain is profitable, regardless of the source of feed. Also, keep in mind the increased intake due to milk production is in addition to what the cow needs to eat to maintain bodily functions. As with increasing cow weight, stocking rate must be reduced as level of milk increases to adjust for increased cow dry matter intake.

Lewis also found that in the low milking cow group, as calf weaning weight increased, postweaning gain decreased. What does this mean? Calves from lower milking cows, while weaning slightly lighter calves, may have weaned at a lower fat composit ion t h e r e f o r e having a g r e a t e r propensity for postweaning compensatory gain. The calves from the lower milking cows compared to calves from the high milking cows were 35 pounds lighter at weaning

but were only 19 pounds lighter at slaughter, which was not significantly different. Additionally, steers from lower milking cows showed a better feed:gain ratio in the feedlot. Not only does increasing milk production in cattle decrease cow efficiency, it even decreases the efficiency of their steer and heifer progeny.

In conclusion, increasing cow mature weight and level of milk production will improve calf weaning weights in a non-limiting environment. However, the consequences include increasing cow forage and supplement intake



FEATURE(continued from page 21) leading to a decreased stocking rate, increasing milk to gain ratio of the calves, increasing cow nutrient requirements, and decreasing postweaning gains and feedlot efficiency. In effect these signs all lead to increasing calf weaning weights at a decreasing efficiency. In a limited environment, selecting for increased mature weight and milk production could be potentially devastating to a ranching operation by decreasing calving percentage and cow stayability. Regardless of environment, selecting for increasing cow size and milk will reduce the efficiency of turning forage into calf weaning weight.

Consider this a challenge to you to make informed decisions regarding your cowherd and be aware of the consequences of selecting breeding animals simply on the basis of maximizing production traits. Remember, the only trait that should be maximized is profit.

Are You and Your Facilities Ready for Pre-conditioning

The beef industry is working on formalizing welfare assessment tools and realizes that third-party audits can be an effective system for ensuring that animal well-being practices are implemented.

The National Cattlemen’s Beef Association has worked diligently to articulate the “Producer Code for Cattle Care,” which are sound production practices. These practices include: 1) To provide adequate food, water and care to protect cattle health and well-being; 2) To provide disease prevention practices to protect herd health; 3) To provide facilities that allow safe and humane movement and/or restraint of livestock; 4) To provide personnel with training to properly handle and care for cattle and; 5) To make timely observations of livestock to ensure basic needs are being met. Persons who willfully mistreat animals will not be tolerated (http : / /w w w.exploreb eef .org/CMDocs/ExploreBeef/FactSheet_AnimalWelfare.pdf).

Clint Peck, the former Director of the Montana BQA program proposed that by following BQA recommendations a rancher could theoretically add significantly to yearly income if the practices shown in Example 1 were implemented.

Working/Processing Cattle Standard Operating

malfunctions or issues that may cause animal or human injury should be reported to (operation manager) immediately.

5. The (manager or trainer name) will be responsible for ensuring that all employees have been properly trained on the operation of the equipment and/or instruments that they are

National BQA programs advocate the usage of scientific information and validated practical knowledge to develop recommendations for best practices, development of self-assessment tools, development of measurable audit processes and the implementation of credible third-party audits.

6. Cattle are much more susceptible to heat stress than cold stress. Processing cattle increases body temperature. It is best to work cattle in the cool portion of the day, and to avoid days in which a large increase in temperature is expected (especially days preceding extremely warm nights).

7. Electric prods will not be used unless the animal is extremely resistant. If the electric prods are used (on greater than 10%) of the cattle (the manager) will be required to (inspect the facilities for physical objects or other conditions that are impeding the

cattle, or to retrain the employees on proper cattle handling, or remove those employees are contributing to cattle handling challenges).

8. All crew members will be trained by the (trainer and/or the veterinarian) on the proper Beef Quality Assurance guidelines on injections, injection techniques, and injection locations.

9. No injections will be given anywhere but in the neck of cattle except by order of the herd veterinarian or as directed by the medication label.

10. All processing tasks will be recorded (on a processing map sheet).

11. Each lot of cattle will be worked according to instructions given (by the operation manager to the head processor). Instructions will be adjusted according to the risk status of each lot of cattle.

12. A protocol for the processing of high- and low-risk cattle will be established by (the herd veterinarian) and applied accordingly to the cattle.

Early Pregnancy DetectionA Tool for Managing and Marketing the Cowherd

Timing of Pregnancy TestPregnancy can be detected in cows

as early as 30 days using ultrasound and blood tests.

For cows to be identified as pregnant utilizing the palpation method, cows often need to be at least 35-50 days pregnant. Experience of the person palpating can make a significant difference on how early in this range that pregnancy can be detected.

Producers should realize that stress to heifers and cows early in pregnancy can result in loss. Research has shown a pregnancy loss of 1-3.5% when palpation or ultrasound are used for pregnancy diagnosis at 40 - 75 days of gestation.

Selling Non-pregnant Cows in August

For cow herds calving January - April, cows can be pregnancy tested in late August and non-pregnant cows sold at that time. Marketing at

this time provides two advantages.The first is that cull cow prices in

August tend to be 5-10% higher than they are in October or November.

The second is that cows that are nursing a calf will typically lose weight from August through the time that calves are weaned due to forage quality having matured and decreasing in its nutritive value.

Selling non-pregnant cows in August when they weigh more and prices are seasonally higher provides the opportunity for producers to capture more value from these cows than leaving the calves on the cows and waiting to pregnancy test at weaning.

Early weaning calves from cows in August will require additional high quality feed and management. However calves at this age are very efficient and the cost of supplemental feed is often not much more expensive than the cost of carrying

the pair.

Comparing Methods of Pregnancy Testing

There are several advantages and disadvantages to each of the three methods of pregnancy testing. In some instances using a combination of these methods within a herd may be a valuable tool to accomplish marketing goals.

A webinar titled “Early Pregnancy Diagnosis, a Management and Marketing Tool” was recently recorded that highlighted pregnancy diagnosis methods and how they can be utilized.

Other ConsiderationsFor producers whose first-

calf heifers calve in the January - May time frame, utilizing early pregnancy diagnosis on these heifers as yearlings provides producers the opportunity to timely market

Early pregnancy detection in replacement heifers or cows is a tool producers can use to increase profit. Traditionally, cows and replacement heifers are pregnancy tested in the fall of the year and then non-pregnant cows and cull cows are marketed at that time. This is also when cull cow prices are seasonally at their lowest.

ADVANTAGES AND DISADVANTAGES FOR THREE METHODS OF PREGNANCY TESTING

When Pregnancy can be Detected Age of Calf Sex of Calf Experienced

Technician Needed? Cost Per Cow When Results Known

Palpation 35-50 Days Yes No Yes $3-$10 Immediately

Ultrasound 30 Days Yes Potentially Yes $7-$15 Immediately

Blood Test 30 Days No No No $3-5 2-4 Days


non-pregnant heifers. These non-pregnant heifers can be marketed as soon as they are identified or a producer may choose to continue to put weight on them and market later if conditions warrant. These non-pregnant heifers may also be implanted provided that ownership will be retained long enough to see the benefit of the implant.

For producers, leaving bulls with the cows for a long breeding season provides the opportunity to potentially get a higher percentage of cows pregnant. Cows that will calve later than desired can be sold to someone else whose calving season fits that time frame. This can be a way to capture additional value from later calving cows that would

otherwise be sold as non-pregnant females in a short breeding season – provided feed resources allow this.

SummaryNon-pregnant heifers and cows

as well as cull/bred cows can provide as much as 20% of the gross income to a cow-calf operation on an annual basis. Taking advantage of opportunities to effectively add value to and market these cows through the use of timely pregnancy diagnosis along with an understanding of market seasonality can allow producers to capture more profit from this segment of the cow-calf operation.

Eight Factors forConfident Vaccine Selection

“Vaccines need to be carefully assessed and chosen to ensure your dairy operation isn’t in danger of a disease outbreak,” says Greg Edwards, DVM, Cattle Technical Services, Pfizer Animal Health. “The investment you make in selecting the right disease prevention products also can help reduce the significant costs and labor associated with disease treatment.”

Dr. Edwards suggests sitting down with your veterinarian to evaluate vaccines based on eight areas of product differentiation and

pick vaccines that best fit your management needs and vaccination program goals. 1. Label indications and levels

of protection: The U.S. Department of Agriculture (USDA) grants label claims based on demonstrated efficacy for each disease organism in the vaccine. These levels of protection include: Prevention of Infection, Prevention of Disease, Aids in Disease Prevention, Aids in Disease Control and Other Claims.

2. Duration of immunity: Duration of immunity (DOI) is the minimum amount of time you can expect a vaccine to help protect your cattle, based on manufacturer efficacy and disease challenge studies. A vaccine’s DOI should help protect during the critical risk period for disease risk. Your veterinarian can help schedule revaccination protocols according to your vaccines’ DOI.

3. Immune response time: Some types of vaccines stimulate protective immunity more rapidly than others. For example, intranasal vaccines can help provide a quick immune response.

4. Modified-live virus vs. killed virus vaccines: Modified-live virus (MLV) vaccines contain live organisms that can undergo limited replication within the body. MLV vaccines can have benefits including rapid immune response,1 comprehensive immune response and duration of immunity,2-4 and few post-vaccination reactions.4

5. Route of administration: Follow the route of administration indicated on the label to help

Not all vaccines are created equal, and the myriad of choices can be confusing. Your veterinarian is the best resource to help you sort through product information and make science-based vaccine recommendations to provide complete protection for your herd. If your cattle aren’t fully protected against

respiratory and reproductive diseases, your herd’s health, productivity and profitability could be at risk.

MANAGEMENTachieve the expected efficacy of the vaccine. Your vaccine choice and preferred route of administration may depend on your management capabilities, and training your employees on administration may be necessary.

6. Safe for use in pregnant cows and calves nursing cows: Choose vaccines that are safe for use during pregnancy to help bolster immunity of the cow and enhance colostrum quality. Having flexibility to revaccinate cows during gestation provides protection against viral shedding and supports herd immunity.

7. Convenience: Vaccines come in a variety of combinations that

can be tailored to fit your disease challenges and management needs. Your veterinarian can help you identify disease risks based on herd history or geographic challenges. When choosing combination vaccines, remember that DOI and levels of protection may be different for each antigen in the vaccine.

8. Cost-effectiveness: Profitability on the operation is important, and cost-effectiveness is always a factor in product selection. Work with your veterinarian to discuss factors that impact a cost-effective vaccine, including management time and labor for administration, vaccine combinations, levels

of protection, duration of immunity, cost of a potential disease outbreak, and price.

Partner with your veterinarian to select vaccines that provide complete protection for your cattle and optimal results for your operation.

INDUSTRYNew Burn - Detection - Modeling

System in Development to Help Identify Potential Wildfire Threats

The modeling system will be used by the Texas A&M Forest Service. Researchers with the Center for Natural Resource Information Technology, part of Texas A&M AgriLife Research, are developing the modeling program. One of those researchers, Dr. Richard Conner, also an AgriLife Research economist and professor in the department of agricultural economics at Texas A&M, said the system is a modification of several modeling projects developed a decade ago.

“This current modeling system measures the amount of forage fuel load in a county and is used to predict potential fire danger,” he said.

The modeling system will provide real-time information on fuel loads using vegetation and National Oceanic and Atmospheric Administration weather information for regions susceptible to wildfire.

“In the wildfire predictive services arena, one of the hardest things to get a handle on is herbaceous fuel load across the state,” said Tom Spencer, head of fire predictive services, Texas A&M Forest Service. “It’s challenging to determine the condition and amount of it. There’s no good way to do that through remote sensing. It’s always been the case where someone

has to physically go out and look, then make a judgment call.

“This project will help determine if it is possible or not. We think it is, but we still need to determine if the science supports it. Overall, we are looking forward to seeing how this helps us understand potential fire season severity, which will help us assist local governments to better plan ahead. It’s a huge deal if this works out.”

The project has received $125,000 in funding by a federal fire plan grant. So far, the project has been implemented in three counties – Stephens, Palo Pinto and Jack. In these counties, researchers have identified major plant communities and developed field monitoring sites to be included as part of an overall web interface monitoring system.

The team members working on the project include Wayne Hamilton, AgriLife Research range scientist, Jay Angerer, assistant professor at the Blacklands Research and Extension Center in Temple, Ed Rhodes, a research associate at Blacklands, and Jason Jones, an assistant research scientist with the department of ecosystem science and management at Texas A&M.

“We will delineate land areas into

ecological sites for an inventory to be used in the modeling system,” Hamilton said. “Ecological sites are areas of the landscape that produce similar kinds and proportions of plant species and total annual yield. This will allow us to expand our field sampling information across similar areas (ecological sites) and save time and costs in the inventory process.”

Ecological sites also provide “state and transition models” that help identify plant communities and changes likely to occur from management inputs, he said.

“What we are hoping to do is to provide vegetation information that the Forest Service can use to monitor potential wildlife threats across regions of the state.”

Angerer and the center’s team have developed the simulation model framework to run the monitoring system. It includes data such as types of vegetative plants growing in a county or region, soil data and historical weather data.

“We are also using NOAA data with the other information on soils and plant communities we have collected to help predict how much vegetation is growing in a particular area,” he said.

Angerer said vegetation samples are

A burn-risk-detection modeling system in development by a consortium of Texas A&M University System researchers will help predict potential wildfire threats throughout the Lone Star State, according to its developers.


INDUSTRYclipped to help calibrate the model. A similar system was developed during a research project at Fort Hood. The collected data, along with remote-sensing information, will be used to identify similar sites in the county so that the entire county can be monitored.

“Once we get the model working, the model will provide a base view of vegetative characteristics of a particular site, and can use this to see how many similar sites we have in an area,” he said. “We then can model these points and build landscape maps of potential fire threats.”

The plant community database is built by taking measurements of plant cover and clippings of vegetation in the field.

“We take the basal area of grasses and measure the canopy cover of shrubs,” Angerer said.

The project uses the PHYGROW modeling system, which computes grass, herb and shrub growth, forage consumption by livestock, and hydrologic processes. The project also uses the Burning Risk Assessment Support System, or BRASS, which is a decision support tool that provides a continuous means for land managers to assess vegetation and weather to support decisions related to prescribed burning and/or the risk of wildfire by utilizing near real-time weather conditions and fuel loads.

The PHYGROW model was first coded in 1990 and has undergone many enhancements since that time. The model’s original computation algorithms are a mixture of formulas adapted from other plant growth models, as well as biological relationships from grass-tiller-

level research and livestock dietary selection conducted at Texas A&M University.

“The PHYGROW model is capable of simulating growth of multiple species of plants subject to selective grazing by multiple animals on a soil with multiple layers for indefinite periods of time,” Conner said. “The model is designed to be integrated with a wide variety of weather databases, vegetation databases and stocking rule databases, and provides output for a wide variety of data sources and formats including all relational databases.”

BRASS, they explained, is a web-based interface that allows users to examine fire risk for points using an interactive map interface. Simulation modeling of rangeland forage and grazing dates back to the late Dr. Jerry Stuth, an AgriLife R e s e a r c h scientist, who, working with Conner and H a m i l t o n , started the initial Ranching Systems Group seeking research funds for i n f o r m a t i o n t e c h n o l o g y research.

The new m o d e l i n g tool will aid Forest Service personnel in tackling the c h a l l e n g e

of changing range conditions throughout Texas, especially since land has changed ownership through the years and traditional management practices vary.

“Some land is not grazed as heavily as a tract say next door where there may not be any cattle on the property,” Conner said. “There’s fuel build up there and an increasing risk of wildfires. There’s more risk than there used to be, due to people having more land and using it for purposes (other) than cattle production to make money.”
