Abstract
According to the weight of the grazing sheep in 1987-2007,the minimum value appeared in April,and the maximum in October.The average gained weight was 0.086 3 kg/d during warm-season,but lost 0.049 6 kg/d during cool-season.The analysis with grey correlation suggested that the temperature and wind speed contributed to the change of sheep weight.
