The current study aim.d to com.are the effects of increasing concentrations of dietary threonine (Thr), tryptophan (Trp), and glycine (Gly) on growth perform.nce, stress biom.rkers, and intestinal function in broiler chickens under m.ltiple stress conditions. Five hundred sixty broiler chickens at 21 d old were random.y allotted to 5 treatm.nts with 8 replicates. Birds in a positive control (PC) treatm.nt were raised under low stock density (16.9 birds/m.2) per cage) with recom.ended environm.ntal conditions, whereas birds in 4 treatm.nts were subjected to m.ltiple stress conditions: a cyclic heat stress of 30 +/- 0.3 degrees C for 10 h and 23 +/- 0.2 degrees C for 14 h per day with high stock density (25.3 birds/m.2) per cage). A basal diet was assigned to both PC and negative control (NC) treatm.nts. Three additional diets were individually form.lated to contain double concentrations of digestible Thr, Trp, or Gly + Ser com.ared with their concentrations in the basal diet. The experim.nt lasted for 14 d. Results showed that NC treatm.nt had less growth perform.nce (P m.nt. Thr treatm.nt showed the least (P m.ng treatm.nts under m.ltiple stress conditions. Thr, Trp, and Gly treatm.nts had less (P = 0.026) feather CORT concentrations, but had greater (P m.nt. In conclusion, increasing concentrations of dietary Thr, Trp, or Gly im.rove the growth perform.nce and intestinal health in broiler chickens with decreasing stress response under m.ltiple stress conditions.
