摘　　要：试验针对重庆市夏季高温 ,应用自我开发的“家畜微电脑自控喷雾降温装置”对奶牛热应激防制效果进行了考核。结果表明 ,采用该装置可使牛舍内温度降低 3℃ ,直肠温度降低0 .65℃ ,平均皮温 (背 /腹 /腋 )降低 3.1℃ ,但舍内湿度增加 3% ;日均泌乳量比对照组提高2 8.0 %～ 30 .3% 。In order to prevent heat stress of dairy cattle caused by high temperature in summer, auto-spraying equipment with microcomputer control was developed. Results showed that when this apparatus was used in dairy cattle sheds, temperature in cattle shed, rectum temperature of cattle, mean skin temperature was decreased by 3℃,0.65℃ and 3.1℃, respectively, while the humidity of the shed increased by 3%. Average daily milk yield of treatment group was 28.0% to 30.3% higher than control group, which demonstrated that this apparatus had a good heat stress prevention effects.
