ASCI 001 Lecture Notes - Lecture 10: Hindgut Fermentation, Short-Chain Fatty Acid, Rumen
Document Summary
Nutrition the study of the body"s need and mechanisms of acquiring, digesting, absorbing, and metabolizing nutrients. Feed costs may account for 45% to 75% of the costs of animal production. Dietary components digested by enzymes and absorbed in small intestine. Have a rumen before the acid bath stomach. Rumen microbes (bacteria protozoa) utilize the animals feed for their nutrition. Fermentation produces gases, volatile fatty acids (vfas) and billions of microbes. Much of the feed energy absorbed from rumen as vfas. A substance in the diet that supports the normal functions of the body. Water sufficient water quality and quantity are key to life animals health, well-being, and performance significantly affected by poor water/inadequate supply. Some nutrients cannot be synthesized by the body at all, or cannot be synthesized in amounts adequate for good health. Dietary sources can be augmented by microbial synthesis in gi tract i. e. ruminants get amino acids and b-vitamins from their rumen microbes.
