Overview

• Anatomy and digestion• Metabolic Efficiency• How do we maximise Metabolic Efficiency?

Anatomy and digestion• The main parts of the digestive tract

– 1. Stomach– 2. Small Intestine – 3. Cecum/Large Intestine– 4. Liver (and associated organs)

Anatomy and digestion

• 1. Stomach– Secretion of enzymes and

hydrochloric acid • pH = approx 2

– Main enzymes = proteolytic (protein digestion)

– Low pH important for• Partial / total eradication of microbes• Hydrolysis of proteins • To optimise pH-dependant protease

enzyme function

Protein digestion in stomach

Acid

Acid dependant proteolytic enzymes

Small Intestine• 2. Small Intestine

– Alkaline secretions results in ~ neutral pH– Digestion of smaller protein chains (polypeptides) into amino acids– Absorption of amino acids– Bile secretion to emulsify fats, similar to detergent action (break apart

globules to allow for enzyme attack)

~ neutral pH

~ neutral pH dependant protease enzymes

Cecum/ Large Intestine• 3. Cecum/ Large Intestine

• Fermentation chamber• No enzyme secretion

– therefore enzyme activity due to “carry over” from small intestine or microbial enzyme production

• Similar in many ways to rumen• Microbial fermentation = 8-16% of

digestion in pig• A low protein digestibility in the stomach /

small intestine can lead to higher protein levels in the large intestine and an “E. coli friendly” environment

• E. coli has been related to oedema disease

Liver• 4. Liver

– Metabolism of absorbed nutrients – Storage organ for many minerals / certain

vitamins– Energy storage to control blood glucose

(glycogen can be approx 8% of liver fresh weight)

– Bile production for effective fat digestion

– Main site for detoxification (e.g., mycotoxins)– Synthesis of blood components– Hormone manufacture e.g., IGF (Insulin-Like

Growth Factor)

“Metabolic Efficiency”Gross Energy Total energy of feed

Faecal Energy Digestible Energy

(DE) Energy "available" in blood

Urine Energy

Methane Energy Metabolisable Energy

(ME) Energy available at tissue levelHeat Energy

(during metabolism) Net Energy

(NE) Energy deposited in tissue /

end product (meat, milk, eggs)

How do we maximise Metabolic Efficiency?• First focus on on-farm solutions

• Quality of raw materials– Digestibility– Voluntary feed intake– Mycotoxins, etc

• Correct and up to date formulations• Genetics• Feed processing • Management

– Temperature / humidity– Quality of housing / floors– Stress factors (e.g. overcrowding)– Well-trained staff

• Disease

• What can we offer?

How do we maximise Metabolic Efficiency?

Acidpro• Unique Organic Acid blend

researched and developed in South Africa for local conditions

• Unique combination of organic acids improves digestibility and feed efficiency through several mechanisms

• Improved pH conditions to allow for higher rate of protein digestion• Reduced protein in hindgut • Reduced risk of E. coli and associated endotoxin related disease

Acidpro• Acidpro is more than just an

ordinary organic acid blend

• Also contains pre- and pro-biotics to ensure that beneficial micro-organisms are established and that they proliferate

• Competitive exclusion of harmful micro-organisms

ClexVit• ClexVit is a mycotoxin

binder with a difference

• 3 pronged approach• 1. Toxin binding• 2. Toxin deactivation• 3. Immune stimulation

ClexVit• ClexVit is a mycotoxin binder

with a difference

• 1. Toxin binding• Different types of clay• 4 different yeast cell walls (exo-

and endo-toxin binding)• Nanotechnology / advanced

grid spacing– Large surface area

ClexVit• ClexVit is a mycotoxin • binder with a difference

• 2. Toxin deactivation• Enzyme forming yeasts• Liver stimulating additives

ClexVit• ClexVit is a mycotoxin

binder with a difference

• 3. Immune stimulation• Natural vitamin E• Organic Zinc and Selenium• Phosphorus improves

carbohydrate and protein metabolism

ClexVit• ClexVit is a mycotoxin

binder with a difference

• 1 – 6 kg / ton depending on type of pig and severity of mycotoxin problem
