| 摘 要： | 针对我国南方夏季炎热和冬季阴冷潮湿的气候特点,得到此环境气候下的肉牛体感温度公式,并以此指导实际生产。选取6头15月龄西门塔尔牛,测定其环境干球温度(DBT)、湿球温度(WBT)和风速(V)及其皮温。结果表明:干湿球温度与皮温呈正相关(冬季:rd=0.92,P0.01;rw=0.86,P0.01;夏季:rd=0.75,P0.01;rw=0.60,P0.01)。在我国南方冬季气候环境下,肉牛的体感温度公式为ET=0.81DBT+0.19WBT-2.99V(r=0.87,P0.001);夏季体感温度公式为ET=0.28DBT+0.72WBT-1.93V(r=0.93,P0.001)。
