摘　　要：试验聚焦于探究不同的降温方式对兔舍环境温、湿度指标的影响,以及对肉兔生产性能指标、血清抗氧化指标的作用。选择初重接近的健康5周龄断奶新西兰肉兔480只,随机分为4个处理组,每个处理组6个重复,每组重复20只兔兔(公母各半)。对照组不采取降温措施,试验组分别采取吊扇、诱导风机以及诱导风机+喷淋3种降温方式,试验期35d。结果:与对照组相比,3个试验组平均温度均显著降低(P<0.05);诱导风机+喷淋组湿度相较其他组明显升高(P<0.05),且温湿度指数最低。使用吊扇和诱导风机后空气风速显著增大(P<0.05),氨气浓度明显降低(P<0.05)。与对照组相比,3个试验组试验肉兔的最终体重和成活率均明显升高(P<0.05);吊扇组的平均日增重和料重比无显著差异(P>0.05);诱导风机组与诱导风机+喷淋组平均日增重均显著增加(P<0.05),料重比显著降低(P<0.05)。与对照组相比,3个试验组试验肉兔的血清超氧化物歧化酶与总抗氧化能力明显升高(P<0.05),丙二醛浓度显著降低(P<0.05)。其中,诱导风机+喷淋组的效果显著优于其他2个试验组。This experiment focuses on exploring the effects of different cooling methods on the temperature and humidity indicators in rabbit houses,as well as their impacts on the production performance indicators and serum antioxidant indicators of meat rabbits.Four hundred and eighty healthy 5-week-old weaned New Zealand meat rabbits with similar initial weights were selected and randomly divided into 4 treatments,with 6 replicates per treatment and 20 rabbits(half males and half females)per replicate.The control group received no cooling measures,while the experimental groups were subjected to three cooling methods:ceiling fans,induced draft fans,and induced draft fans+sprinklers.The trial period lasted for 35 days.Results:Compared with the control group,the average temperature in the three experimental groups was significantly lower(P<0.05);the humidity in the induced draft fans+sprinklers group was significantly higher than that in the other groups(P<0.05),and the temperaturehumidity index was the lowest.The air velocity increased significantly(P<0.05)and the ammonia concentration decreased significantly(P<0.05)after using ceiling fans and induced draft fans.Compared with the control group,the final body weight and survival rate of the rabbits in the three experimental groups were significantly higher(P<0.05);there was no significant difference in average daily gain and feed conversion ratio in the ceiling fan group(P>0.05);the average daily gain in both the induced draft fan group and the induced draft fans+sprinklers group increased significantly(P<0.05),and the feed conversion ratio decreased significantly(P<0.05).Compared with the control group,the serum superoxide dismutase and total antioxidant capacity of the experimental rabbits in the three treatment groups were significantly increased(P<0.05),and the malondialdehyde concentration was significantly decreased(P<0.05).Among them,the effects in the induced draft fans+sprinklers group were significantly better than those in the other two treatment groups.
