试验选用24日龄‘科宝’肉仔鸡528只,随机分配到11个处理组中,每个处理组8个重复(公母各4个重复),每个重复6只鸡,以10份不同来源菜籽粕作为蛋白质唯一来源配制成10种半纯合日粮,同时添加无氮日粮组作为内源基础对照,分别测定不同来源菜籽粕回肠表观氨基酸消化率(AID)和回肠真氨基酸消化率(TID).结果表明：性别对肉仔鸡回肠末端内源氨基酸基础损失量(BAAL)、AID和TID 无显著影响(P>0.05)；不同来源菜籽粕的肉仔鸡AID和TID 存在显著性差异(P<0.05),其中6号菜籽粕(来源武威)AID和TID 均显著高于其他来源菜籽粕(P<0.05)；5号菜籽粕(来源临洮)蛋氨酸消化率最低,7号菜籽粕(来源定西)赖氨酸消化率最低.结果显示,不同来源菜籽粕回肠表观氨基酸消化率及真氨基酸消化率差异显著(P<0.05).

528 heads of 24-day old ‘Cobb’broilers were allocated randomly into 11 groups to assess the variation of ileal apparent amino acid (AID)and true amino acid (TID)of different sourced rapeseed meal in broilers,with 8 replicates (half male)per group and 6 birds per replicate.Ten kinds of half purified diets based on 10 different sourced rapeseed meal samples were formulated and one another non-nitrogen diet was prepared as an endogenic control to determine the AID and TID of them.The results showed that there were not significant differences among groups in the loss of endogenous amino,AID and TID affected by gender of broilers(P≥0.05).Amino acid digestibility of different sourced rapeseed meals were signifi-cant differences(P<0.05).No.6 rapeseed meal which from Wuwei was higher at AID and TID than those of others(P<0.05).There was lowest methionine digestibility for No.5 samples which from Lintao and the No.7 samples (from Dingxi)had lowest lysine digestibility.There were significant differences among different sourced rapeseed meal samples at both AID and TID(P<0.05).
