摘要
将 39日龄肉鸡置于 4 2℃高温环境中 3h,分别在热应激后 4、2 8、52 h采血检测血浆纤维连接蛋白( FN)和某些血清生化指标 (血糖、尿酸、总蛋白、白蛋白、胆固醇、谷草转氨酶、T3 、T4)的变化 ,以研究高温对肉鸡生理、代谢等方面的影响及寻找判断应激的指标。结果表明 ,血浆 FN浓度在高温刺激后 2 8h明显高于对照组 ;血清谷草转氨酶活性在 2 8、52 h后明显比对照组高 ;总蛋白、白蛋白在 4 h后明显比对照组低 ;其他血清生化指标在高温刺激下均无显著变化。
In this experiment,39 day old broilers were reared at high temperature(42℃,3 h) and plasma fibronectin(FN) levels and other selected serum biochemical parameters(GLU,UA,TP,ALB,CHO,AST,T 3,T 4) were evaluated at 4 h,28 h,52 h after heat stress respectively,to study the effect of high temperature on physiological and metabolism aspects of broilers and to find a monitor of stress.The results showed as follows:plasma levels of FN in experimental group were higher than that in control group significantly after 28 h treatment of high temperature;Serum AST values were higher than that in control significatly after 28 h and 52 h treatment of high temperature;serum TP and ALB values were lower than control;all other parameters evaluated remained unchanged.The results indicated that high temperature could induce selective increase in circulating leves of the acute phase protein fibronectin in broilers.
