内蒙古天然牧场冬季饮水温度对羊的影响研究

Study on the effect of drinking water temperature on sheep on natural pastures in Inner Mongolia in winter

为了研究内蒙古天然牧场冬季饮水温度对羊的食草量、饮水量、体重减轻量、羔羊成活率、产毛量等生产性能的影响,试验采用实地观测的方法,利用试验与对照相结合,分析不同饮水温度对羊生产性能的影响因子。结果表明:随着饮水温度的提高,有孕羊和无孕羊的饮水量和进食量增加,体重减轻量降低,羔羊成活率和产毛量提高,羊的生产性能向有利于生产的方向发展。说明提高冬季饮水温度对发挥羊生产潜力具有重要作用,对牧场供水和提高经济效益具有重要意义。

To study the effect of drinking water temperature on sheep productive performances in winter, including h^rbivorous amount, drinking water quantity, amount of weight loss, lamb survival rate,＇ wool yield, and so on, a method of field observation was used to analyze the influen- cing factors in productive performances of sheep with different drinking water temperatures using test in combination with control. The results showed that the drinking water quantity and food intake of pregnant and non - pregnant sheep increased with the increase of drinking water tem- perature. While the amount of weight loss decreased; the lamb survival rate and the wool yield also increased. It was suggested that the produc- tive performances of sheep also developed to the direction which was beneficial to the production. The results indicate that drinking water tem- perature in winter plays an important role for developing sheep production potential, and has great significance for ranch water supply and impro- ving the economic efficiency.
