摘  要：
本研究对10周龄兴义鸭进行体尺性状和屠宰性能测定,并对所测指标进行显著性检验及相关性分析,结果表明,公、母鸭各体尺指标间的差异均达到了显著水平(P<0.05),屠宰指标除瘦肉率显著低于母鸭(P<0.05),腿骨重和肌胃重显著高于母鸭(P<0.05)外,其他指标未达到显著性差异水平(P>0.05);相关分析显示,兴义鸭各体尺指标间的相关性均达到了显著水平(P<0.05),多数屠宰指标间呈现显著相关(P<0.05),其中肺脏与其他指标间的相关性最小;多数体尺性状和屠宰性状间都达到了显著相关水平(P<0.05);胸肌重与胫长、胫围呈显著偏负相关(P<0.05),肌胃重与半潜水长、龙骨长、胫围呈显著偏正相关(P<0.05)。以上结果将为兴义鸭今后的研究提供基础数据,为兴义鸭的进一步选育提供重要的理论参考依据。

摘  要：
The research measured body size traits and slaughter performances and carried out the significance test and correlation analysis for 100 ten weeks old Xingyi ducks.The results indicated that the difference of body size traits was significant from different sex ducks(P<0.05),the slaughter performances had no significant difference except that the lean meat percentage of male were significantly lower than female and weight of leg bone and muscular stomach were significantly higher than female(P<0.05);The correlation analysis showed that all body size traits had a significant correlation,the majority of slaughter performances showed a significant correlation(P<0.05),and lung showed a little correlation with other traits in Xingyi ducks;The majority of body size traits showed significant correlation with slaughter performances(P<0.05);The weight of pectorales showed significant negative partial correlation with stank length and stank girth(P<0.05),the weight of muscular stomach showed significant positive partial correlation with length from beak to hip all,keel bone length and stank girth(P<0.05).These results will provide a fundamental statistics for study on Xingyi ducks in the future and as a insight for selection of Xingyi ducks.
