相同营养条件下五种鸡肉肌苷酸及其相关代谢物含量的比较研究

Comparative Research on The Contents of IMP and Its Correlative Metabolites of Different Chicken Meat in Uniform Nutritional Condition

选用健康正常的1日龄宫廷黄鸡、快大黄鸡、广西黄鸡、罗曼蛋鸡和白羽肉鸡各120只,在相同营养条件下饲养至98日龄时屠宰,测定并比较各品种鸡的肌肉肌苷酸及其相关代谢物含量。试验结果如下,对于HYP的含量,罗曼蛋鸡极显著高于宫廷黄鸡和快大黄鸡(P<0.01),显著高于广西黄鸡(P<0.05),其它各品种间差异不显著(P>0.05)。对于IMP含量,宫廷黄鸡和快大黄鸡极显著高于白羽肉鸡(P<0.01)并显著高于罗曼蛋鸡(P<0.05),白羽肉鸡显著低于广西黄鸡(P<0.05),其它各品种间差异不显著(P>0.05)。对于INO含量,宫廷黄鸡和广西黄鸡极显著低于白羽肉鸡(P<0.01)。对于AMP含量,白羽肉鸡极显著高于广西黄鸡、宫廷黄鸡和快大黄鸡(P<0.01),罗曼蛋鸡显著高于广西黄鸡和快大黄鸡(P<0.05),宫廷黄鸡极显著低于罗曼蛋鸡(P<0.01)。对于ADP含量,宫廷黄鸡、广西黄鸡和快大黄鸡显著高于罗曼蛋鸡和白羽肉鸡(P<0.05)。校正IMP含量在各品种间均无显著差异(P>0.05)。

120 healthy 1-day-old Gongting yellow chickens(Y), crossbred yellow chickens(K), Guangxi yellow chickens(G), Roman laying chickens(L) and AA broiler chickens(B) were raised respectively in the uniform nutritional and feeding condition. On the last day of the feeding experiment, 30 chickens from each group were taken out randomly, slaughtered and analyzed the contents of IMP and its correlative metabolites. The results showed as follows:About the content of HYP, L was extremely significantly higher than K and Y(P<0.01),and higher than G(P<0.05),the difference was not significant among the others(P>0.05). About the content of IMP, Y and K were extremely significantly higher than B(P<0.01)and significantly higher than L(P<0.05),B was significantly lower than G(P<0.05),the difference was not significant among the others(P>0.05). About the content of INO, Y and G were B extremely significantly lower than B(P<0.01). About the content of AMP, B was extremely significantly higher than G, Y and K(P<0.01), L was significantly higher than G and K(P<0.05),Y was extremely significantly lower than L(P<0.01). About the content of ADP, Y, G and K were significantly higher than L and B(P<0.05). About the corrected IMP, there were not significant difference among all chickens(P>0.05).
