摘要
为了测定电热水槽的使用效果,更好地解决寒冷地区冬季奶牛饮用热水的问题,在舍外平均气温-17℃的条件下,对电热水槽内的水温进行了连续测定,并对泌乳牛的饮水行为进行了观测。结果表明:电热水槽仅能提供7.2℃的温水,无法满足冬季所有奶牛随时饮用到适宜热水的需求;挤奶前后、饲喂前后是泌乳牛饮水的高峰时间。
To determine the effect of using electric heating water through, and better solve the problem of dairy cows drinking thermal water during the winter of cold regions, the water temperatures in the electric heating water through were continuously, measured, and the dairy cows＇ drinking behaviors were observed under the condition of an average temperature of - 17℃ at the outside of the barn. The results showed that the electric heating water through could only provide 7.2℃ of warm water, and could not satisfy the needs of all the dairy cows drinking suitable thermal water at any time in winter. Before and after milking and feeding was the peak time of dairy cows drinking water.
