摘　　要：笔者于2006—2007年,在内蒙古乌兰察布市四子王旗王府一队内蒙古农牧业科学院试验基地进行不同载畜率水平下的绵羊牧食行为试验研究。试验结果表明,不同载畜率对绵羊采食行为、反刍行为有明显影响,载畜率低时能明显降低采食时间,延长反刍时间,而对其他保养及排泄行为影响不大。The experiment was conducted in stipa breviflora desert steppe in Wang fu number one group, experimental base of Agriculture and Animal Husbandry. Academy, Siziwang banner, Wulanchabu league of Inner Mongolia from 2006 to 2007.Different stocking rates were set up with sheep in order to study grazing behavior of sheep in response to stocking rate. The results showed that the foraging and ruminant behaviors of sheep were significantly affected under different stocking rate. The biting time was obviously reduced while the ruminating time was prolonged when the stocking rate was low. However, the different stocking rates had little impact on other maintenance and excretion behaviors.
