摘要
2002年春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,定量研究了自然放牧状态下成年科尔沁牛牧食行为。结果表明,科尔沁牛的平均采食时间为511.36±222.07min,反刍时间为66.38±14.60min,卧息时间为46.50±42.97min,站立时间为10.75±7.98min,游走时间为58.10±20.13min。平均采食速度为62.00±13.04口/分,平均采食量为10.38千克/头·天。对苔草草甸进行的受控放牧试验表明,主要牧草的选择性采食顺序为香茅>蒲公英>马蔺>芦苇>苔草。
The grazing behavior of Kerqin cattle was studied with the whole day long eye observation method in the spring of 2002 at a natural pasture. The results showed that average time for foraging was 511.36±222.07 minutes, ruminating time was 66.38±14.60 minutes, resting time was 46.50±42.97 minutes, standing time was 10.75±7.98 minutes, and the time for wandering was 58.10±20.13 minutes. The rate of ingestion in average of Kerqin cattle was 62.00±13.04 bite/min. The grasstaking rate in average was 10.38 kg/cattle·day. The results of the controlled grazing experiment on the carex meadow showed that the order of preferred plant species were Hierochloe odorata>Taraxacum mongolicum>Iris Iactea var. chinensis>Phragmites communis>Carex.
