Fattening sheep in a warm shed to compensate for energy deficiency in winter in north‐west China

摘要：

Grasslands in north‐west of China can experience extremely cold weather conditions which can restrict forage quality and quantity.This leads to a situation of low sheep growth rates and poor body condition.The main reason for low sheep growth rates is the additional energy requirements required to resist cold not being met by forage supply.In theory, improving energy intake can have the same effect as increasing shed temperature.FACS is a kind of by‐pass rumen fat and energy additive,and research has shown that feeding it can improve ruminant ADG ( Lai,2002; Zhao,2001).In this experiment,we added FACS to a sheep diet so as to test the effect on fattening sheep in both a warm and ordinary shed.
