南海麻黄鸡血清T3，T4水平差异及其与屠体性状的相关分析

The Relevance of Blood Serum T3 and T4 Difference with Carcass Traits in High Quality Meat Chickens

采用放射免疫分析法对84日龄南海麻黄鸡A系、B系鸡的血清T3,T4含量及其与部分屠体性状的相关性进行了测定和分析。结果表明:南海麻黄鸡A系母鸡、B系母鸡血清T3,T4含量均是B系母鸡高于A系母鸡,南海麻黄鸡B系母鸡的T3/T4比值小于公鸡。血清T3水平值与各屠体性状呈现正的弱相关或中等相关,而血清T4的水平值则多表现为负相关;血清T3/T4比值与各屠体性状表现出显著正相关。

The Radia Immunitos Array（RIA） was used to measure the blood serum T3 and T4 contents of the 84-day-age Nanhai Yellow Chicken （A strain ＆ B strain） ,and their associations with carcass traits were analyzed. The result showed that the contens of blood serum T3 and T4 in B strain female chickens were all higher than those in A strain female chickens. The T3/T4 value of B strain female chickens was lower than that of B strain male chickens. The content of T3 had weak or middle relevance to carcass traits, but the content of T4 had negative relations with carcass traits in most cases, while the T3/T4 value presented the significant possitive relations with carcass traits.
