为了研究同品种绵羊在不同放牧环境下的牧食行为差异,在典型草原区沙质草地和高平原草地两种放牧环境下,对四品种双杂交杂种绵羊的牧食行为进行了观察.结果表明:不同放牧环境下绵羊的采食时间和游走时间占放牧时间的80%左右,放牧环境对采食行为有显著的影响.绵羊在沙质草地采食和游走时间占总放牧时间的66.5%和15.63%,在高平原草地为77.9%和7.79%.不同放牧环境下卧息、站立等时间存在显著差异.
In order to study the same species of sheep if have differences in different circumstances, we observation foraging behavior of sheep on daytime in the typical prairie sand region and in the typical steppe.The result showed: The intaking and wandering time of the sheep occupy about 80% to foraging daytime in different foraging environment, which have remarkable difference influence. In the typical sand region the intaking and wandering time of the sheep is 66154% and 15163%, 77149% and 7179% in the typical steppe.There are remarkable differences in sleeping and resting time, standing t ime and so on under different grazing environment.
