畜舍温度是养畜节约饲料、获得增重的先决条件之一。在时间、地点、饲养条件等同的条件下,对同样的肉牛,当舍温为4.6～22.0℃时,可日增重0.5公斤;当舍温为-5.0℃时,日增重为0,不增不减;当舍温降至-10.0℃时,出现负值,俗称“掉膘”。在漫长的冬季,牲畜为了抵抗低温而多耗能量达10.0～20.0％。来自锡盟的调查资料表明,奶牛舍温低于-10.0℃时,产奶量下降10.0～15.0％。无灾
The temperature of a livestock house is one of the preconditions for raising livestock to save feed and gain weight. Under the same conditions of time, place and feeding conditions, for the same beef cattle, when the shepherd temperature is 4.6 to 22.0°C, the daily weight gain can be 0.5 kg; when the shepherding temperature is -5.0°C, the daily gain is 0, not Increases are not reduced; when Shewen falls to -10.0°C, a negative value occurs, commonly known as “dropout.” In the long winter, livestock consume more energy from 10.0 to 20.0% to resist cold temperatures. Survey data from Ximeng indicated that when the temperature of dairy cows was below -10.0°C, the milk production decreased by 10.0 to 15.0%. No disaster
