摘　　要：该试验为探究开化翻毛鸡体尺、屠宰性能和肉品质指标及相关性关系,选取43周龄的健康翻毛鸡30只(公、母各15只),测定体重体尺、屠宰性能和肉品质,并对体重体尺与屠宰性能采用Pearson法进行相关性分析。结果表明,翻毛鸡公鸡体斜长、龙骨长、胫长、胫围指标极显著高于母鸡;公鸡全净膛率和半净膛率极显著高于母鸡,其他屠宰性能差异不显著;体尺与屠宰性能方面,宰前活重与屠体重、体斜长、胸深、胸宽、胫长、半净膛重、全净膛重、胸肌重、腿肌重呈显著正相关,体斜长与龙骨长、胸深、胸宽、胫长、胫围、半净膛重、全净膛重、胸肌重、腿肌重呈显著正相关;肉品质方面,公鸡的腿肌肉色a^(*)显著大于母鸡。试验表明,开化翻毛鸡公鸡的产肉性能高于母鸡,体尺与屠宰性能相关性较高,腿肌率较高。文章结果为开化翻毛鸡地方资源的保护利用提供数据支撑。In this experiment,30 healthy chickens(15 males and 15 females)were selected at 43 weeks of age to investigate the correlation between body weight,body size,slaughter performance and meat quality,and the correlation between body weight,body size and slaughter performance was analyzed by Pearson method.The results showed that the body slope length,keel length,tibia length and tibia circumference were significantly higher in males than in females;the rates of semi-eviscerated and eviscerated were significantly higher in males than in females,but the differences in other slaughter properties were not significant;in terms of body size and slaughter performance,body weight before slaughter was strongly positively correlated with carcass weight,body slope length,breast depth,breast width,shank length semi-eviscerated weight,eviscerated weight breast muscle weight and leg muscle weight.In terms of meat quality,the leg muscle color a^(*)was significantly greater in males than in females.The test showed that the meat production performance of Kaihua frizzle roosters was higher than that of hens,the correlation between body size and slaughter performance was higher,and the leg muscle rate was higher.The results of this paper provide data support for the conservation and utilization of the local resources of Kaihua Frizzle chicken.
