摘  要：
试验测定12周龄隐性白羽鸡不同日粮营养水平下的屠宰性能,结果显示:①性别对产肉量、除腿肌率外的产肉率、副产品量、除翅率外的副产品率有极显著或显著影响,上述指标中,除胸肌率、腹脂重、腹脂率、肝率、肌胃率指标为母鸡大于公鸡外,其余均表现为公鸡大于母鸡;②两种能量水平仅对12周龄体重、屠体重、半净膛重、全净膛重、腹脂重、腹脂率、肌胃重、肌胃率有显著或极显著影响;③高蛋白质水平显著提高12周龄体重、全净膛重全净膛率、胸肌重、胸肌率,低蛋白质水平显著增加腹脂重、腹脂率、肝重、肝率;④产肉量的遗传力中等偏高为0.36～0.43;产肉率的遗传力差异较大为0.10～0.49;屠宰副产品量的遗传力差异较大为0.16～0.59,副产品率的遗传力中等偏高为0.25～0.77。

摘  要：
The experiment measured the slaughter performance of the recessive white chicken rearing under rations with different nutrition levels at 12 weeks. the results showed:sex had significant or very significant influence on meat production,meat production rate except for the percentage of leg muscle,by-production and by-production rate except for the percentage of wing. The percentage of breast muscle,abdominal fat,abdominal fat rate,liver rate and muscular stomach rate for hens were higher than that for cocks among all the slaughter index above,but the others indicated lower in hens. The two energy levels only had significant or very significant influence on the body weight of 12th weeks,dressed weight,half-eviscerated weight,eviscerated weight,abdominal fat weight,abdominal fat rate,muscular stomach weight and muscular stomach rate. High protein level could observably promoted the body weight of 12th weeks,eviscerated weight,eviscerated rate,breast muscle weight and breast muscle rate,and the low protein level could observably promoted abdominal fat weight,abdominal fat rate,liver weight and liver rate. The heritability of meat production and by-production rate were respectively 0.36 to 0.43 and 0.25 to 0.77,that were higher than middle level. The heritability of meat rate and by-production were variable,which were respectively 0.10 to 0.49 and 0.16 to 0.59.
