Document Summary
Some protein degradation through action of pepsin (enzyme) secreted in gastric juices. Trypsin and peptidase which further degrade protein to amino acids. Converts starch and sugars into glucose c. d. Pancreatic lipase converts fats into fatty acids which can be absorbed. Bile also aids in fat and fat soluble vitamin absorption. Major site of digestion and absorption of nutrients. Microbial protein not utilized much by horse due to a lack of enzymes. Coprophagy: eating of feces when there is a severe protein deficient in the diet; requires a higher protein feed. A horse is 2/3 less efficient than ruminants at utilizing food. Known as the "paunch" and accounts for 20% of the body weight. Where microbes (bacteria/protozoa) are located and cellulose and starch are broken down into vfa"s (anaerobic environment) Vfa"s are absorbed and used for energy (50-70%) Microbes and rumen have a symbiotic relationship; rumination allows for more surface area for microbes.
