THE INFLUENCE OF DIETARY TRYPTOPHAN LEVELS ON PLASMA TRYPTOPHAN CONCENTRATIONS AND MEAN DAILY GAIN IN BROILER CHICKS

Liu Limal;Sun Wenzhi;Tong Bing (Northeast Agricultural University,Harbin 150030,PRC)  
Experiments were conducted to determine how different levels of dietary tryptophan (Trp) influence the plasma Trp concentrations and mean daily gain of broiler chicks at 7~8 weeks of age.Within limits,a quadratic effect of dietary Trp levels was observed on both plasma Trp concentrations (P0.05) and mean daily gain (P0.05).The requirement of the male broiler chicks at 7~8weeks of age for Trp was estimated to be 0.165, at least crude protein levels of 18.77%.
