14

True or False: Protein needs decrease with age

True (once an animal reaches peak growth rate, they are consuming more feed with a lower protein concentration and once they reach maturity, they are consuming less feed and protein)

25

Function of microminerals

regulate enzyme systems

26

Mineral deficiency causes:
