巢湖鸭屠宰性能测定与性状分析

作者旨在对初步进行本品种选育的巢湖鸭体组成性状进行测定分析，为进一步选育优质肉用巢湖鸭新品系奠定基础。选择60只（公母各30只）经本品种选育一代的10周龄的巢湖鸭，屠宰并测定胴体、半净膛、全净膛、胸肌、腿肌、皮脂、腹脂等性状指标，对巢湖鸭公母鸭间的屠体性状指标进行统计分析。结果表明,公母鸭屠宰率、全净膛率、腿肌率、皮脂率、胸肌剪切力、腿肌剪切力差异不显著（P>0.05)；母鸭的半净膛率、胸肌率、瘦肉率显著高于公鸭(P<0.05)；公鸭的骨肉比显著高于母鸭 (P<0.05)。相关分析显示,各屠宰重量指标间有极显著的正相关(P<0.01)，屠宰率指标与体重相关不显著（P>0.05)，半净膛率、腿肌重、胸肌率、心脏重与性别显著相关(P<0.05)。说明初步选育的巢湖鸭具有较好的屠宰性能和产肉性能，肉质较好。

Testing and Analysis of Body Composition Traits for Chaohu Ducks

Body composition traits of Chaohu ducks selected within the breed were tested and analyzed to breed the new meat-type strains of Chaohu ducks.Sixty Chaohu ducks(thirty males and thirty females) with 10 weekages were slaughted and detected the carcass traits including carcass weight,eviscerated weight with giblets,eviscerated weight,breast muscle,leg muscle,abdominal fat,subcutaneous fat and so on.Statistics analysis was carried out for these traits.The results showed that there were no significant differenc...
