ASCI 112 Lecture 5: ASCI 112 - Nutrition, Digestion & Endocrinology Lecture Series
Document Summary
The science of understanding how animals and people convert foods to their chemical components (nutrients) and use (metabolize) them for maintenance, growth, and production. Energy and components sufficient to support baseline physiological functions of an animal at present size. Additional energy/components needed to increase animal"s size at the same rate (ex- lbs/day) Additional energy/components needed to support greater physiological functions of animal than are needed for maintenance or growth at present size. Fuel (energy) - monosaccharides such as fructose, glucose, galactose. Causes cows to alter feeding preferences to correct issue. Chlorophyll may help detoxify harmful substances like heavy metals. Essential (can"t be synthesized internally) (have to be eaten) Non-essential (can be synthesized by amino acids) (produced by body) Animals vary in their dietary requirements for vitamins. This may be related to the kinds and number of microorganisms in their digestive tract (many of which are capable of synthesizing one or more vitamins.
