摘要
在锡林郭勒草原对三种放牧绵羊(蒙古羊、引种羊、杂种羊)进行不同月份的牧食行为观察及采食量测定,结果表明:放牧绵羊9月份的采食时间比例均高于8月份;沙质草地放牧绵羊的采食和游走时间比例低于高平原草地;蒙古羊、引种羊和杂种羊沙质草地的平均采食量分别为1.15kg/d、1.60kg/d和1.35kg/d,高平原草地为1.56kg/d、1.82kg/d和1.71kg/d,分别相差0.41kg/d、0.22kg/d和0.36kg/d。
The grazing behavior of three kinds of grazing sheep was observed,and feed intake was measured in different month in Xilingol steppe.The results showed that intaking time proportion in grazing time of grazing sheep in September were more than in August.The intaking and wandering time ratio of grazing sheep in the sand grassland was less than that in the high plain grassland.The feed intake of Mongolia sheep,introduced sheep and cross sheep were 1.15kg/d,1.60kg/d and 1.35kg/d in the sand grassland,which were 1.56kg/d、1.82kg/d and 1.71kg/d in the high plain grassland,difference value were 0.41kg/d,0.22kg/d and 0.36kg/d,respectively.
