不同放牧强度对新疆褐牛的牧食行为影响

Influence of Different Grazing Gradients on Xinjiang Brown Cattle Grazing Behavior

【目的】研究不同放牧强度下新疆褐牛的牧食行为。【方法】在试验区设置轻度放牧(BA1)、中度放牧(BA2)和重度放牧(BA3),采用跟踪观察法观察新疆褐牛的牧食行为。【结果】7月,三种不同牧压下新疆褐牛的采食时间>反刍时间>卧息时间>游走时间>饮水时间,反刍时间是BA1>BA2>BA3,且BA1与BA2和BA3有显著差异(P<0.05);8月份,采食时间BA3与BA1和BA2存在显著差异(P<0.05),卧息时间BA1与BA2有显著差异(P<0.05)。【结论】在一天的放牧中采食和反刍是新疆褐牛的主要牧食行为。

[ Objective ] To study the influence of different grazing gradients on Xinjiang Brown Cattle grazing behavior. [ Methods] Three grazingpatterns were set in the testing area： light grazing （BA1 ）, moderate grazing （BA2） and heavy grazing （BA3 ） to keep track of Xinjiang Brown Cattle grazing behavior. [Results] In July, under the three different grazing pressures, Xinjiang Brown Catde＇s behavior is： ingestive time 〉 ruminating time 〉 resting time 〉 wandering time 〉 drinking time, and their rnminatiing time is： BA1 〉 BA2 〉 BA3. A Significant difference appears between BA1 , BA2 and BA3 （P 〈 0.05 ） ;In August ingestive time under BA1, BA2 and BA3 is significantly different （P 〈 0.05）, and there is a big difference between sleeping and resting time under the patterns of BA1 and BA2 （ P 〈 0.05 ）. [ Conclusion ] Ingestion and rumination are the major and important behavior of Xinjiang Brown Cattle during the whole day.
