本试验研究了高赖氨酸日粮中苏氨酸(Thr)与赖氨酸(Lys)的最佳比例是否能改善现代肉鸡肥育期鸡的生长性能，并通过代谢组学分析确定了高赖氨酸日粮或Lys+Thr日粮提高肉鸡生长性能的可能机制。将18只21日龄笼养雏鸡随机分为3组，每组6只，分别饲喂不同日粮：对照组、高赖氨酸日粮(高赖氨酸含量为150%)和高赖氨酸+苏氨酸日粮(高赖氨酸日粮中苏氨酸/苏氨酸之比为0.68)。饲喂高赖氨酸日粮的雏鸡增重显著高于对照组(P
Here, we investigated whether the optimal threonine (Thr) to lysine (Lys) ratio in high Lys diet improves the growth performance of modern broiler chickens at finisher period and determined the possible mechanism underlying improvement in the growth performance of chickens fed with high Lys or Lys + Thr diet using metabolome analyses. Eighteen 21-day-old chickens housed in individual cages were randomly divided into three groups of six chickens fed with different diets as follows: control diet, high Lys diet (150% Lys content of National Research Council requirement), and high Lys + Thr diet (0.68 of Thr/Lys in high Lys diet). Body weight gain (BWG) increased in chickens receiving high Lys diet as compared with those fed with the control diet (P
