energy and protein Flashcards
food is composed of what 2 things
- water
- dry matter (minerals and organics)
outline the metabolisable energy system
what is metabolic rate
expenditure of energy per given time
what is fasting metabolic rate
energy expenditure for basic life processes at rest, fasting in a thermoneutral environment
What does the term ‘metabolizable energy’ refer to
Energy that can be used by the animal after accounting for losses.
outline the metabolisable protein system
what is undegraded dietary protein
- protein that escapes digestion in rumen
undegraded dietary protein is dependent on:
- rumen outflow rate
- protein source
what is conversion efficiency
Conversion efficiency refers to the efficiency of converting energy from one form to another within a biological system. In the context of the Metabolisable Energy System, conversion efficiency is quantified using the term Animal Production Level (APL) to measure how efficiently an animal is working above its maintenance requirements. The efficiency can vary depending on factors such as the quality of the diet and the specific use to which the energy is put.
