Abstract:

本试验旨在研究饲粮中添加不同水平包被蛋氨酸对肉鸡生长性能、血液生化指标和氨基酸表观回肠消化率的影响。选用18日龄科宝500肉鸡3780只,按试验要求随机分为7组,每组设3个重复,每个重复180只鸡。对照组(A组)饲粮添加0.16%的消旋蛋氨酸(DL-Met),试验组饲粮添加含量为50%的包被蛋氨酸,添加量分别为饲粮的0.32%(B组)、0.29%(C组)、0.26%(D组)、0.22%(E组)、0.19%(F组)、0.16%(G组)。饲喂至42日龄结束。结果表明:B组和C组末重、平均日增重和平均日采食量均显著高于对照组(P<0.05),B组死亡率显著低于对照组(P<0.05),其他组与对照组均差异不显著(P>0.05);各试验组(除G组外)血浆谷胱甘肽过氧化物酶活性均显著高于对照组(P<0.05),B组和C组血浆总超氧化物歧化酶活性均显著高于G组(P<0.05),其他生化指标各组间均差异不显著(P>0.05);各试验组干物质和粗蛋白质表观回肠消化率均与对照组差异不显著(P>0.05),除G组多种氨基酸表观回肠消化率显著低于对照组(P<0.05)外,其他试验组的各种氨基酸表观回肠消化率均与对照组差异不显著(P>0.05)或显著高于对照组(P<0.05)。结果提示,随着包被蛋氨酸添加量的增加,肉鸡生长性能逐渐改善,氨基酸回肠消化率逐渐提高。饲粮添加0.19%包被蛋氨酸(替代对照组60%的蛋氨酸)即可满足肉鸡需要,即采用包被方式后,蛋氨酸最多可节约40%。
