中文摘要:
      对成年兴义鸭进行肉质性状和血清生化指标测定袁并对所测性状和指标进行显著性检验及相关性分析,结果表明,兴义鸭雄性和雌性肉质性状差异不显著,公鸭的球蛋白、白球比值、碱性磷酸酶、甘油三酯、总胆固醇、总蛋白与母鸭的差异显著(P约0.05),其中只有白球比值公鸭低于母鸭,其他各差异显著性状均为公鸭高于母鸭。肉色与酸度呈极显著正相关(P约0.01),与嫩度呈显著正相关(P约0.05);总蛋白与白蛋白、球蛋白、乳酸脱氢酶、总胆固醇呈极显著正相关(P约0.01),总胆固醇与甘油三酯呈极显著正相关(P约0.01);酸度与白球比值呈显著负相关,与乳酸脱氢酶呈显著正相关(P约0.05), 失水率与乳酸脱氢酶呈极显著负相关(P约0.01)。该结果对鸭肉质的改善起到参考作用,为更深入开展血清生化指标与肉质性状的研究奠定理论基础,为兴义鸭的生化遗传标记辅助选择提供理论依据。
英文摘要:
      The serum biochemical indices and meat quality traits of adult Xingyi duck were measured,the significance testing and correlation analysis were carried out subsequently in this study. The results showed that there was no significant difference in meat quality between male and female individuals, however, the contents of globulin (GLO),alkaline phosphatase (AKP), triglyceride (TG), total cholesterol, total protein in drake individuals were significantly higher than female ducks (P<0.05) except for Alb/GLO ratio among various serum biochemical indices. Additionally, there were significant positive correlation between the flesh colour and tenderness (P<0.05) and even reached the highly significant positive level for flesh colour and acidit of different ducks (P<0.01). For the serum biochemical indices, it demonstrated that there were highly significant positive correlation between the total protein and many other indices including albumin,globulin, lactic dehydrogenase (LDH) and total cholesterol (P<0.01), moreover, the similar correlation also existed in total cholesterol and TG (P<0.01). However, there were significant negative correlation between acidity and Alb/GLO ratio and highly significant negative correlation between driage and LDH, the correlation between acidity and LDH was significantly positive (P<0.05). The results could be treated as a reference for the study on improving the duck meat quality, and laid the foundation for study on serum biochemical indices and meat quality traits of duck, also provided theoretical basis for marker assisted selection of biochemical genetics marker of Xingyi duck.
