摘要
为了研究抗热应激品种麒麟鸡(卷羽鸡)的肉用开发价值,试验对12周龄麒麟鸡体尺性状和屠宰性能进行测定及相关性分析,并构建简单回归方程。结果表明,12周龄麒麟公鸡龙骨长和胫长显著高于母鸡(P<0.05);12周龄麒麟公鸡活重、屠体重、半净膛重、全净膛重和腿肌重显著高于母鸡(P<0.05),腹脂重和皮脂厚显著低于母鸡(P<0.05),其余指标公、母差异不显著(P>0.05);麒麟鸡屠宰性能与体尺性状绝大多数存在显著或极显著相关性,并建立了主要屠宰性状的回归模型,为通过麒麟鸡活体的体尺测量结果预测屠宰性能指标提供一定理论依据,同时加速了麒麟鸡的遗传育种进程。
In order to study the meat development value of anti-heat stress species-Kirin chicken(Frizzle chicken),12-weekold Frizzle chicken was used to measure their body size traits and slaughter performance indexes and then studied these data with correlation and regression analysis.The results showed that keel length(12.05cm)and shank length(8.70cm)of male 12-week-old Frizzle chickens were significantly higher than those of female chickens(10.17,7.47cm)(P〈0.05).The live weight,carcass weight,semi-eviscerated weight,eviscerated weight and the leg muscle of male 12-week-old Frizzle chickens were significantly higher than those of female chickens(P〈0.05),abdominal fat weight(27.22g)and sebum thick(4.38mm)were significantly lower than those of female chickens(35.33 g,5.12mm)(P〈0.05),other indicators were no significant differences(P〈0.05).There were highly significant or very highly significant correlations between the slaughter performance and body size in Frizzle chicken.The regression equation of related indicators was identified.This conclusion provided a certain theoretical reference to predict slaughter performance indicators through a living body size measurements and contributed to the genetic breeding process of Frizzle chicken.
