摘要
2013年8-10月,采用模拟采食法、群牧差额法、内外指示剂结合法在昭苏马场草甸草地上进行了放牧条件下乳用伊犁马采食量的测定。结果表明,1)同种测定方法不同月份之间测定的乳用伊犁马干物质采食量差异不显著(P>0.05)。2)模拟采食法测得的干物质采食量为12.79 kg·15 h-1·匹-1,群牧差额法测得为16.39kg·d-1·匹-1,内外指示剂结合法测得为13.28 kg·d-1·匹-1。3)群牧差额法与内外指示剂结合法测定的乳用伊犁马干物质采食量之间差异不显著(P>0.05),初步确定乳用伊犁马平均干物质采食量为14.83 kg·d-1·匹-1。
The feed intake of dairy Yili horse under grazing conditions was tested in Zhaosu meadow steppe by simulating feed method,herd difference method as well as internal and external indicator method from August to October in 2013.There was no significant difference between different months of the feed intakes of dairy Yili horse determined by the same method.The dry mass intakes measured by simulating feed method,herd difference method and internal and external indicator method was 12.79 kg·15 h-1·horse-1,16.39 kg·d-1·horse-1and 13.28kg·d-1·horse-1,respectively.The difference between the dry mass intakes measured by herd difference method and internal and external indicator method was not significant(P > 0.05) and the dry matter intake was initially identified as 14.83 kg·d-1·horse-1.
