摘要
本试验通过模拟北京地区高温季节气温变化状况，对２１０日龄的北京红鸡进行２７～３４℃的连续热应激试验。结果表明，血糖、总蛋白、血脂以及Ｔ３、Ｔ４、Ｈ／Ｌ均处于先升后降，并在７～１２天左右达到相对稳定。连续的血气分析及对血清离子的分析表明，ｐＨ从热应激开始后的前４天为７．３３７～７．３９４，未超出正常生理变化范围，ＨＣＯ－３、ＰＣＯ２，ＡＢＥ经检验均无显攻差异，只是绝对值在热应激开始后有所下降。为缓解热应激给蛋鸡生产造成的影响，必须采取措施以缓和高温带来的危害。
The experiment was to studied on the law of blood biochemical parameters in the range of 27～34℃ successive heat stress by using 210days 72 layers of Beijing Red. The result showed that:GLU、TP、TG、H/L and T 3、T 4、all increased first then declined following and reached relatively steady in 7～12 days。 In other way,running analyzed to the parameters on blood gas and ion of serum showed that the change of pH in 7.337～7.394 in 4 days did not excess the normal range,there was slight declined on HCO - 3、P CO 2 、ABE and K、Na、Ca(P>0.05) in heat stress。 All of these results would show a theoretical basis for studying the law of heat stress and taken measure for relaxing the effects of high temperature.
