摘要
１９９７年春季（５月中下旬）在内蒙古锡林郭勒盟多伦县测定了蒙古牛的牧食习性，研究了蒙古牛的采食、站立、游走、卧息、反刍、饮水和排泄行为。研究结果表明，蒙古牛的平均采食时间为５０８．１±５５．５ｍｉｎ，共计６．３±２．１个采食周期；反刍时间为３８６．８±５４．６ｍｉｎ；卧息时间２４４．９±６１．０ｍｉｎ；站立游走时间３００．２±７９．０。平均采食速度７．６±８．１口／ｍｉｎ，平均采食量１０．１０ｋｇ／头·ｄ。蒙古牛春季采食的牧草种类主要为单子叶植物中的禾本科、莎草科、百合科和鸢尾科植物。
The grazing behavior of Mongolian cattle during 24-hour period, including the behavior of foraging, standing, wandering, resting, ruminating, drinking, urinating and defacating, was observed in the spring of 1997 at a natural pasture in Duolun County. The forage and water intake of Mongolian cattle was measured. The selective grazing was investigated. The results showed that average time for foraging during 24-hour period was 508.1±55.5 minutes, the time for ruminating was 386.8±54.6 minutes, standing and wandering time was 300.2±79.0 minutes, and the time for resting was 244.9±61.0 minutes. The rate of ingestion of Mongolian cattle was 57.6±8.1 bite/min at average. The average ingestive intake was 10.10kg/cattle. day. The main plants that Mongolian cattle foraged in spring were some species of Gramineae, Cyperaceae, Liliaceae and Iridaceae.
