Efficiency of protein utilization by growing chinchilla fed two levels of protein. Rogier, John Charles

Abstract

Six male and six female chinchilla (Chinchilla lanigera) in the late phase of growth were used to study the effects of sex, crude protein level in the ration and duration of experiment on body weight gains, digestibility of energy, dry matter, organic matter and protein and efficiency of protein utilization, as measured by biological value and net protein utilization. Two isocaloric rations of differing crude protein content (16.25% and 19.56%) were supplied ad libitum for three one-week experimental periods. The results showed that female chinchilla had significantly (P
