摘　　要：研究0.5%抗热应激剂1号(主要成分VC、VA、VE)、0.5%抗热应激剂2号(主要成分碳酸氢钠、氯化钾等电解质)和1.0%抗热应激剂3号(主要成分生石膏、金银花、黄芩、藿香、党参、苍术、甘草等12味中草药粉碎后按一定比例混合配制),这3种不同的抗热应激剂在夏季高温环境对3月龄健康、体重相近的獭兔的生长性能和营养消化率等指标的影响。结果表明:在高温季节獭兔日粮中添加抗热应激剂,试验组与对照组相比平均日采食量、平均日增重分别提高1.52%～7.94%、5.87%～17.75%,料重比降低4.27%～9.33%,成活率提高3.56%～7.15%,粗蛋白质、粗脂肪、粗纤维、钙和磷的消化率分别提高2.30%～6.24%、1.16%～3.26%、2.40～9.13%、3.58%～5.03%和2.05%～8.61%。以抗热应激剂2号效果较佳。The effects of three kinds of anti-heat stress additives on production performance and nutrition digestibility of 3-month-old Rex rabbit in summer were studied,including 0.5 ％ anti-heat stress additives No.1（main components of VC,VA,VE）,0.5 ％ anti-heat stress additives No.2（main components of sodium bicarbonate,potassium chloride,etc）,and 1.0 ％ antiheat stress additives No.3（components of gypsum,honeysuckle,scutellaria root,agastache,Codonopsis,Atractylodes,licorice and the other 12 kinds of herbs,mixing in proportions after crushing）.The results showed that daily feed intakes in experiment group were 1.52％ ～7.94％ higher than that in the control group,and average daily body gains were improved by 5.87％～17.75％,ratio of feed to gain were decreased by 4.27％～9.33％,survival rate were improved by 3.56％～7.15％,and crude protein,crude fat,crude fiber,calcium and phosphorus digestibility were improved by 2.30％ ～6.24％,1.16％ ～3.26％,2.40～9.13％,3.58％ ～5.03％ and 2.05％～8.61％,respectively;The anti-heat stress additive No.2 was good.
