| 摘 要： | 本试验分别用无氮日粮法和绝食法测定肉仔鸡内源氨基酸损失量,并比较两种方法得到的结果之间的差异.选用49日龄健康的AA肉仔鸡公鸡20只,随机分成2组,每组10只,采用48 h空腹+48 h全收粪法进行试验.结果表明,无氮日粮法和绝食法测定的肉仔鸡内源氨基酸中,精氨酸、苏氨酸、胱氨酸、酪氨酸内源损失量之间无显著性差异(P＞0.05);无氮日粮法测定的其他氨基酸内源损失量极显著(P＜0.01)或显著(P＜0.05)高于绝食法;无氮日粮法测定的总氨基酸内源损失量极显著(P＜0.01)高于绝食法.

| Abstract: | The aim of this paper was to determine endogenous amino acid losses in broilers by Nitrogen-free diet method(NFD)and fasting method(FAS)and compare the difference of the two methods.Twenty 49-day-age healthy AA broiler chickens were divided into two groups randomly,ten broilers each group.The broilers were fasted 48 h and the endogenous amino acid losses were detected by collecting all excrement in 48 h.The results showed that endogenous arginie,threonine,cystine,tyrosine losses determined by NFD were simil... |
