贵妃鸡与麒麟鸡杂交F1代的体尺性状、屠宰性能及相关分析
为了研究贵妃鸡的肉用开发价值,以贵妃鸡为父本、麒麟鸡为母本进行杂交探索.对12周龄F1代杂交鸡进行体尺性状、屠宰性能测定及相关性分析,结果表明:12周龄F1代杂交公鸡的体斜长、龙骨长、胫长均显著高于母鸡,F1代杂交公鸡的活体重、屠体重、半净膛重、半净膛率、全净膛重、胸肌重、腿肌重和心脏重极显著高于母鸡,腿肌率、翅膀重显著高于母鸡而皮脂厚却极显著低于母鸡,其余指标公母差异不显著.屠体性能与体尺性状绝大多数存在显著和极显著相关性,并确定了相关指标的回归方程,为通过活体的体尺测量结果预测屠体性能指标提供一定的理论依据,同时试验结果表明F1代杂交鸡的生产性能显著提高....

Bibliography: | 44-1267/S hybrid chicken; body size; slaughter performance; correlation analysis LI Nai-bin, YANG Fen-xia, DU Bing-wang, TAO Lin, CHEN Jie-bo (Department of Animal Science, Guangdong Ocean University, Zhanjiang 524088, China) In order to study the meat development value of princess chicken, the body size traits and slaughter performance of 12-week-old F1 hybrid offspring of princess chicken ( ♂ ) and frizzle chicken ( ♀ ) were measured and the correlations between different traits were analyzed. The results showed that body length, keel length and shank length of male F1 hybrid offspring were significantly higher than those of female chickens. The live weight, carcass weight, semi-eviscerated weight, semi-eviscerated ratio, eviscerated weight, chest muscle weight, leg muscle weight and heart weight of male chickens were very significantly higher than those of female chickens, the leg muscle ratio and wings weight were significantly higher than those of female chickens, but sebum thick of male chickens was very s |
