摘　　要：为兴义鸭的选育及科学养殖提供理论依据,随机选取同批出雏、健康无病、体况相近的10周龄兴义鸭50只(公母各半),进行肉质性状测定及其相关性分析。结果表明:兴义鸭具备优良的肉品理化特性,保水性好,肌内脂肪含量和嫩度适中,脂肪酸以棕榈酸、硬脂酸、油酸和亚油酸为主,含量在95.23%左右,不饱和脂肪酸含量(57.075%)高于饱和脂肪酸(42.944%),且多不饱和脂肪酸较丰富。公母鸭脂肪酸含量无显著差异(P>0.05);pH值与肉色呈显著正相关(P<0.05),与失水率呈显著负相关(P<0.05);不饱和脂肪酸间及其与SFA、EFA、UFA间多数呈极显著相关,C17:0与pH值呈显著负相关,C14:0、C16:1、C18:0、C18:1、C18:2、C20:3、C20:4、EFA与嫩度呈显著或极显著相关(P<0.05或P<0.01)。兴义鸭具有良好的肉质特性,是一个值得开发的优良地方鸭品种。To provide the fundamental references for selecting and further studying about Xingyi duck,50ducks（♂：25,♀：25）which were 10 weeks old,healthy,similar body condition,were randomly selected as experimental samples,the meat qualities were analyzed and correlation of the meat qualities were studied.The results showed that Xingyi duck had good physicochemical property and water retention,moderate intramuscular fat content and tenderness;The content of palmitic acid,stearic acid,oleic acid,linoleic acid was very high,which occupied about 95.230%;unsaturated fatty acid（57.075%）was much more than saturated fatty acid（42.944%）;component of polyunsaturated fatty acids was abundant,analysis showed that fatty acid composition between female and male had no significant difference（P〉0.05）;pH value had significant positive correlation with meat color（P〈0.05）and had significant negative correlation with water loss rate（P〈0.05）;The unsaturated fatty acids had highy significant correlation with SFA,EFA,UFA.C17：0 and pH value reached a significant negative correlation（P〈0.05）;C14：0,C16：1,C18：0,C18：1,C18：2,C20：3,C20：4,EFA and tenderness reached a significant level（P〈0.05 or P〈0.01）.Comprehensive analysis showed Xingyi duck had good meat qualities.It may be a potential local breed.
