血浆甲状腺激素(T_3、T_4)与肉仔鸡胴体性状相关性研究

Studies on the Correlation of Plasma Thyroxine Hormon with Carcass Traits in Broilers

本研究比较罗曼和印地安河两肉鸡品种在脂肪沉积上的差异,探讨血浆甲状腺激素(T_3、T_4)与胴体性状的相关性.结果表明,印地安河鸡脂肪沉积显著高于罗曼.血浆甲状腺激素与体脂肪呈负相关,与瘦肉量呈显著正相关(r=0.37以上).甲状腺激素有可能做为选择瘦肉型鸡的指标.

Two hundred chickens from two commercial broiler strains were sampled for comparing their difference in fat deposition and the correlation between plasma thyroxine hormon(T_3,T_4) and carcass traits.Results showed that the fat deposition of Indian river was significantly higher than that of Roman at 7 weeks of age.Plasma thyroxine hormon(T_3,T_4)were negatively correlated with body fat and significantly pos- itively correlated with the amount of leanness.Plasma T_3 and T_4 may be a good criterion for leanness selection in broilers.
