荒漠草原不同放牧方式绵羊牧食策略研究

Studies on Grazing Behavior Under Different Grazing Systems on Desert Stepper

划区轮牧使绵羊采食范围缩小,采食站重叠;使草地得到均匀利用,较自由放牧的采食时间缩短,卧息、反刍和站立的时间延长;无论采食量还是所获得的消化能量和蛋白质均高于自由放牧。

Animal spatial selection behaviors were modified by rotational grazing, which reduced the grazing area, overlaid the grazing stations, and made more evenly uses of grasslands. Animals in the rotational system had a shorter grazing time, longer time for resting, ruminating and standing. High feed intake, as well as high digested energy and proteins, were achieved with rotational grazing.
