Meat-and-bone meal (MBM), which had been heated (150 degrees C) for 0, 1.5, 3 or 5 h, was used along with an indigestible marker in four diets which were fed to young growing chickens and adult cockerels fitted with ileal cannulae. The ileal digesta from each group of birds were sampled and the apparent amino acid digestibilities of the four diets containing MBM were determined. The apparent digestibility values from growing chickens were higher (P less than 0.05) than those from cannulated cockerels. Differences in apparent digestibility of amino acids between diets as a result of heat treatment were consistent for all amino acids when comparing both techniques, with the exception of glutamic acid and arginine.
将经过0、1.5、3或5小时加热（150摄氏度）的肉骨粉与一种不可消化标记物一起用于四种日粮中，将这些日粮喂给安装了回肠插管的幼龄生长鸡和成年公鸡。对每组鸡的回肠食糜进行采样，并测定含有肉骨粉的四种日粮的表观氨基酸消化率。生长鸡的表观消化率值高于（P<0.05）插管公鸡的表观消化率值。比较两种技术时，热处理导致的日粮间氨基酸表观消化率差异对于所有氨基酸都是一致的，但谷氨酸和精氨酸除外。
