为研究日粮中添加γ-氨基丁酸对热应激大鼠子代发育和抗氧化功能的影响。选用90日龄的Sprague-Dawley大鼠52只(雌性大鼠39只,雄性13只)进行试验,交配后27只受孕雌鼠随机分为三组,正常对照组,热应激组和GABA热应激组,仔鼠出生后1天,测定发育指标和肝脏抗氧化指标。结果显示:与正常对照组相比,热应激组新生雌鼠和雄鼠的尾长均显著降低(P

The effects of dietary γ-aminobutyric acid （GABA） on development and antioxidant ability of neonates of heat-stressed rats were investigated.52 rats aged 90 days,39 females and 13 males,were the experimental subjects.27 pregnant rats were randomly divided into three groups after mating：the control group,the heat-stressed group and the GABA heat-stressed group.The development indiced and hepatic antioxidant indices of 1 d neonates were measured.The results showed that tail lengths of the female and male neonates from the heat-stressed group ...
