This experiment studied the effect of different energy restriction levels on amino acids and fatty acids of Arbor Acres(AA)broiler breeders during the initial laying period.240 AA broiler breeders(27weeks old)with similar body weights were randomly divide into four groups with six replicates per group and10 birds each replicate.The experiment was conducted when laying rate reached 5%.The birds in the control group were fed the basal diet,and those in trial groups were fed the diets with 80%,70%and 50%energy...
