Effect of different protein levels of feedstuffs on endogenous energy losses of roosters



Effect of different protein levels of feedstuffs on endogenous energy losses of roosters



Chinese Journal of Animal Science 39(4): 18-19



Twenty-four 400-day-old healthy Hy-line Brown adult roosters at liveweight of 3+or-0.1 kg were selected and randomly divided into 3 groups. Roosters were fed with maize meal, soyabean meal and fish meal, with protein contents of 8.4, 43.5 and 64.5%, respectively. The endogenous energy and nitrogen losses of the fish meal group were the highest, followed by that of the soyabean meal group.
