1·The results showed that optimal addition of dietary Lys and Met could improve the performance of pheasants.
结果表明：饲粮中适量添加赖氨酸和蛋氨酸均可改善其生产性能。
2·The proteolysate has been found to contain 16 kinds of amino acids with essential amino acids content about 50% and Lys content about 15—17% of the total amino acids.
氨基酸分析结果表明，水解蛋白含有16种氨基酸，必需氨基酸含量为总蛋白量的50％左右，赖氨酸含量达15—17％。
3·With reciprocal effect of Met and Lys, daily gain of all groups had no significant difference during the whole period (P>0.05).
在蛋氨酸和赖氨酸不同水平协同作用下，前后期各处理组鸡只的日增重均无显著性差异（P＞0.05）。
4·The results showed survival rate of all groups were 100%, i. e. levels of Met and Lys had no influence on cockerel health.
结果表明：各组试验鸡成活率均为100%，说明日粮蛋氨酸、赖氨酸水平对鸡只健康无影响。
5·This study was conducted to investigate the effects of lysine (Lys), methionine (Met) and threonine (Thr) supplementation on growth performance and serum biochemical parameters of calves.
本试验旨在研究赖氨酸、蛋氨酸和苏氨酸对犊牛生长性能和血清生化指标的影响。
