肉牛舍温热环境对肉牛生理指标的影响

The Thermal Environment Influence on the Physiology Target on Beef Cattle in Beef Cattle Cowshed

肉牛舍的温热环境指标如温度、相对湿度、风速,对肉牛的健康和增重有重要的影响,而且也影响着饲料的采食量及利用率。为了解肉牛舍气温、相对湿度和风速对肉牛直肠温度和呼吸率的影响,对肉牛舍温热环境指标和肉牛的生理指标进行了测定、分析。结果表明:肉牛舍内、外的6个测点,在同一时刻,温度、相对湿度指标均无显著差异(P>0.05),牛舍内、外不同测定点通风效果存在差异;新型牛舍与河南省的气候条件相适应,在豫南地区甚至河南省都可以推行。

The index of thermal environment in beef cattle cowshed like temperature, the relative hu- midity, the wind speed, have the important influence on weight gain and health, moreover also affects the appetite of feed to the pick and the use factor. In order to understand that what the influence of tempera- ture, the relative humidity and the wind speed of beef cattle cowshed to the rectal temperature and breath- ing rate of beef cattle, the determination, analysis of hot environmental index and beef cattle＇s physiologi- cal target in the beef cattle sherwin were carried out. The result indicated： 6 stations inside and outside Beef cattle cowshed, in the identical time, the temperature, the relative humidity target were not remarka- ble difference （ P〉 0.05 ）, the ventilate effect at different station inside and outside cowshed existed difference. The new barn adapted to climate conditions of Henan Province, even in the south of Henan Province or the whole Henan Province. Through the installation of ventilation equipment or spray facilities can meet the requirements of beef cattle fattening hot summer environment, more favorable to the produc- tion of beef cattle in summer .
