【摘要】 在前后期基础饲粮中分别添加０．０％、０．１％、０．２％、０．３％的Ｌ—赖氨酸·ＨＣＬ（基础饲粮赖氨酸含量分别为１．０２％和０．８４％）饲喂海布罗商品代仔鸡，８周龄结束时屠宰分割结果表明：添加赖氨酸对屠宰率、半净膛率、全净膛率、胸肌率、腿肌率、脚重率、翅重率、腹脂率和肌胃重等均无显著影响（Ｐ＞０．０５）；性别对上述前５项指标及肌胃重也无明显作用（Ｐ＞０．０５），但公鸡腹脂率极显著低于母鸡（Ｐ＜０．０１），翅重率和脚重率则明显高于母鸡（Ｐ＜０．０５）。更多还原

【Abstract】 The basal diets with0.0%,0.1%,0.2%and 0.3%of L lyshe·HCL(Lysines in the basal diets are 1.02%and0.84%respectively)were fed to the commer-cial broilers.They were killed to determine carcass compositions at the age of 8 weeks:The results showed that there was no significant effects,with lysine added,upon slaugh-ter,half net carcass,whole net carcass,chest muscle,leg muscle,abdominal fat and stom-ach muscle percentages(P>0.05).Also sex had no effects upon the above 5 indexes andstomach muscle(P>0.05).The abdominal fat percentage of male birds was significantlylower than that of female ones(P<0.01),but wing and foot weight percentage was ob-viously higher than that of female birds.(P<0.05).更多还原
