Effects of grazing forms on seasonal body weight changes of sheep and goats in north-central Mongolia: a comparison of nomadic and sedentary grazing

2016 Volume 27 Pages 27-31


In order to evaluate the effects of concentration of livestock in villages in Mongolia, we compared the body weights of female sheep and goats of different management: a usual “nomadic herd” and an experimental “sedentary herd”. The body weights of the sheep increased from June, peaked in November/December, and declined until March-May. During the decline, the sedentary herd lost more weight than the nomadic herd. In goats, the sedentary herd was heavier at the start in June, but was caught up by the nomadic herd in July. In March of the next year, the nomadic herd became heavier than the sedentary herd. The results showed apparent negative effects of sedentary grazing on body weight of sheep and goats, and suggest the validity of traditional nomadic grazing. It seems an example of traditional ecological knowledge to avoid deterioration of the steppe by overgrazing.
