摘　　要：为研究抗热应激添加剂和维生素C、E对反季节生产的广东鹅繁殖性能的影响,选取1 122只正常反季节产蛋马岗鹅(♀954只,♂168只),平均分为3组,分别为维生素组(添加质量分数为0.08%的维生素C和0.04%的维生素E)、试验组(添加质量分数为0.4%的抗热应激添加剂)和对照组,试验共持续60 d,测定各组的产蛋率、孵化率和受精率.结果表明:在整个试验阶段,维生素组和试验组的产蛋性能、受精率和孵化率均大于对照组,其中两个处理组的受精率显著高于对照组(P<0.05).试验结果表明,反季节生产中抗应激添加剂和维生素E、C对降低种鹅热应激和提高繁殖性能上均具有一定效果,可以显著提高马岗鹅的受精率和产蛋波谷期间的产蛋性能,其中抗热应激添加剂的效果更好.To investigate the effects of anti-heat stress additives and vitamin E/C on the reproductive performance of Guangdong goose in out-of-season production,1 122 normal out-of-season egg-laying Magang geese（ 954 female and 168 male geese） were selected,and were divided into three groups averagely,including vitamins group（ supplemented with 0. 08% vitamin C and 0. 04% E）,test group（ supplemented with 0. 4% anti-heat stress additives） and control group. The experiment lasted for 60 d,and the egg production,fertilization rate and hatching rate of each group were detected. The results showed that the egg production,fertilization rate and hatching rate in the vitamins group and the test group were higher than those in the control group during the entire trial period,and the fertilization rate of the two treatment groups was significantly higher than that of the control group（ P〈0. 05）. The results showed that antiheat stress additives and vitamin E/C had effects on reducing the heat stress and improving the reproductive performance of goose in out-of-season production,which could significantly improve the Magang geese fertilization rate and egg production at trough stage,and anti-heat stress additives worked better.
