摘要: 本研究采用物理方法对奶牛舍实施降温,以达到改善饲养环境条件,保证夏季奶牛健康,提高产奶性能的目的。试验选取10头产奶性能稳定的荷斯坦奶牛随机分成2组,每组5头,分别置于2栋牛舍内,试验组所有牛舍安装通风与喷水装置,对照组不安装。每天11点、14点、16点定时测定舍内平均温度和相对湿度。试验结果表明,试验组牛舍内温度比对照组分别降低10%、12%、9.2%,经检验差异极显著(P<0.01),试验组舍内相对湿度比对照组高1.9%,经检验,差异不显著(P>0.05),试验组产乳量比对照组提高4.5%,经检验差异显著(P<0.05)。试验组乳脂率降低0.33%,对照组乳脂率降低0.16%,经检验差异不显著(P>0.05)。研究结果显示,在常规饲养及管理模式基础上,采用物理降温措施,有助于夏季奶牛生产性能改善。

Abstract: The temperature in cowshed was drop down by adopting physieal measure, to insure cow's heath in summer and promote milk performance. 10 cows of stable milk performance were rardomly divided into two groups. For lower temperature, electric fans and water-pouring instruments were installed in cowshed. The results indicuted: compared wich CK, the temperature decreased by 10%,12% and 9.2% respectively. Through test, the humidity decreased by 0.33%, that of CK decreased by 0.16%, but hadn’t asigmficant difference(P>0.05).The results indicated: physical drop in temperature benefited improving dairy cow performance.
