The Jaylor Advantage
• The ability to process long forage into a uniform mix in a minimum amount of time, to create dairy rations with optimal levels of effective fiber that are resistant to sorting.
![Page 3: The Jaylor Advantage](https://reader035.vdocuments.us/reader035/viewer/2022062323/568164cc550346895dd6ed8b/html5/thumbnails/3.jpg)

Why Total Mixed Rations (TMR)?• Traditional dairy feeding fed forages and
grain (supplements and minerals) separately.• Grain fed to milk production in the parlor,
and later using computer feeders.• With breeding improvement, peak cows
required 50-60 % grain, and >30 lbs/day, causing health and production problems.
• Grain meals greater than 8 lbs causes digestive upset and health problems.
• TMR keeps all ingredients in proportion.
![Page 5: The Jaylor Advantage](https://reader035.vdocuments.us/reader035/viewer/2022062323/568164cc550346895dd6ed8b/html5/thumbnails/5.jpg)
Physically effective fiber• At the same time as milk production and grain
feeding increased, ensiling experts promoted smaller forage particle size to improve silage packing and fermentation.
• Problems arose with depressed milk fat, sub-acute ruminal acidosis (SARA) and displaced abomasums.
• Feeding some long forage alleviated part of the problem
![Page 6: The Jaylor Advantage](https://reader035.vdocuments.us/reader035/viewer/2022062323/568164cc550346895dd6ed8b/html5/thumbnails/6.jpg)
Why put long forage into a TMR?• Long forage provides effective fiber to
promote chewing, prevent digestive upset and increase milk fat production .
• However, it must incorporated into a particle size distribution that resists separation.
• Even longer material in bunker silos must be incorporated adequately to provide a uniform mix that will also resist sorting.
• In beef cattle, incorporating baled forage into a TMR reduces wastage and improves performance up to 30%.

Sorting behavior• Inherent cattle behavior (for ingredient
selection while grazing).• Ingredient preferences.• Learned behavior, hard to stop once
successful.• Strongest in late lactation and older cows.• Aided by excessively long particles in TMR.

Effects of sorting behavior• Affects both sorter and non-sorters.• Increases intake of rapidly fermented
ingredients in sorters.• Low milk fat, increased milk protein, SARA,
feet problems, displ. abomasums, fat cows.• Decreases the energy content of remaining
diet for non-sorters.• Thin cows, decreases peak milk production.

Role of TMR Mixer
• Combine disparate ingredients into a homogenous mix
• Create a mix that resists separation by animals during eating
![Page 11: The Jaylor Advantage](https://reader035.vdocuments.us/reader035/viewer/2022062323/568164cc550346895dd6ed8b/html5/thumbnails/11.jpg)
Particle characteristics affect mix• Particle size, shape, density, #/kg• Inter-particulate forces (electrostatic,
hydroscopic, hydrophobicity)• Best mixing with uniform particle size,
shape and density (e.g. granular fertilizer, commercial feed)
• Differences create tendency to unmix and separate (esp. effective fiber)

Test weighing accuracy and precision
• Clean and inspect weigh bars• Find a helper• Weigh yourself over each weigh
bar with mixer empty. Repeat with mixer full.
• Average of empty and full weights should be within 10 lbs.
• No weigh bar should differ consistently from others, high or low.
![Page 16: The Jaylor Advantage](https://reader035.vdocuments.us/reader035/viewer/2022062323/568164cc550346895dd6ed8b/html5/thumbnails/16.jpg)
How do we measure mix uniformity?• Mix uniformity ultimately involves three
components, and thus two-three measures• First, ensuring we have equal distribution of all
ingredients (esp. grain (starch) vs. forage or digestible fiber) (markers, chemical analysis?).
• Second, ensuring we have equal distribution of all major nutrient groups, i.e. protein, fat, fiber, mineral (chemical analysis).
• Finally, ensuring we have a uniform and acceptable particle size distribution that will prevent sorting (PSPS) and unmixing.

Ingredient sequencing (Vertical)
• Add long forage first (esp. baled hay. Include liquid or water to aid processing)
• Follow with silage and/or wet by products
• Add protein supplement and grains• Pre-weigh and add premixes and
specialty ingredients with grains • Generally add liquid ingredients last
