| 摘 要： | 选取6只2.5岁体重相近而且健康的内蒙古白绒山羊(羯羊、母羊各3只),置于1hrm2人工羊草草地围栏内放牧以观察春、夏、秋、冬四季放牧山羊的行为节律、牧食行为,并计算每天干物质采食量.结果表明:抽穗期羊优先采食草穗,春季过后穗的残余率仅有4.4％；采食速度表现为夏季＞秋季＞春、冬季(P＜0.05)；采食时间占方面时间的比例表现为春、秋＞冬、夏季.每口采食量的季节变化趋势大体为春、夏、冬＞秋季(P＜0.05)；夏季羊的日采食量最高,其次为春、秋,冬季采食量最低(P＜0.05)；同一季节内羯羊的日采食量始终高于母羊(P＜0.05)；春、夏、秋季放牧山羊均有3个进食高峰,分别发生在出牧后约0.5h、午后约0.5h、归牧前2h左右,上午采食量低于下午(P＜0.05).冬季一般上午、下午各一个采食高峰；本试验未发现放牧绒山羊扒食草根的现象,但在卧倒休息或反刍前有扒草、扒土整理休息地的习性,未发现放牧山羊行为节律和采食速度的性别差异.

| Abstract: | Six Inner Mongolia cashmere goats(3 wethers and 3 ewes with similar live weight) were placed in fenced artificial Leymus chinensis grassland of 1hm2 to observe grazing behavior and rhythm in different seasons in whole year.The results showed that the goats preferred to intake grass ear in the heading stage,as there was only 4.4% residual grass ear after spring grazing;the intake rate in summer was the highest,then the autumn,while the intake time in spring and autumn was longer than winter and summer(P<0.05... |
