不同放牧强度下滩羊牧食习性的比较研究

Comparison of Grazing Behavior of Tan Sheep Under Different Grazing Intensity

实验采用跟群放牧全日制观察法 ,研究了不同放牧强度下滩羊的牧食习性 .结果表明 ,随着放牧强度的增大 ,滩羊的采食时间增加 ,反刍卧息时间和游走时间减少 ,每百口采食量和日采食量减少 ,而采食速度增加 .

The experiment was conducted to study on the grazing behavior of sheep under different grazing intensities by the whole day long eye observation method, following flock. The results show that the eating time of sheep decreased and resting and idiling time increased as the grazing intensity became heavier. However,herbage intake per hundred mouths and daily intake decreased, but intake velocity increased as the grazing intensity became heavier.
