摘要
2002年冬季在内蒙古科左后旗的天然草场上,采用跟群放牧全日观察法,定量研究了科尔沁牛牧食行为。结果表明,科尔沁牛的平均采食时间为302．2±26．6 min,反刍时间为13．5±22．4 min,卧息时间为21．6±27．8 min,站立时间为14．1±9．5 min,游走时间为 78．2±26．6 min。平均采食速度为47．9±15．7口/分钟,平均采食量为5．31千克/头·天。日反刍周期出现于午休时间,反刍行为主要在夜间进行,夜间的反刍时间、反刍周期数和反刍总食团数均增加。
The grazing behavior of Kerqin cattle was measured with the whole day long observation method on a natural pasture in the winter of 2002. The results showed that average time for foraging was 302.24±26.6 minutes, ruminating time was 13.5±22. 4 minutes, resting time was 21.6±27.8 minutes, standing time was 14.14±9. 5 minutes, and the time for wandering was 78.2±26.6 minutes. The rate of ingestion of Kerqin cattle was 47.9±15.7 bite/rain en average. The average ingestive intake was 5.31 kg/ cattle · day. The diurnal ruminating cycle appeared in the time of noon break. The ruminating behavior took place mainly at nights Compared to days the time of rumination was longer and the number of ruminating circle and ruminating food bolus were increased at nights.
