摘要 为研究小尾寒羊对四翅滨藜(Atriplex canescens(pursh)Nutt.)饲料养分消化率的影响,选用1年龄小尾寒羊按试验要求随机分为3组,每组3个重复,每个重复1只。分别饲喂Ⅰ组(苜蓿)、Ⅱ组(四翅滨藜)、Ⅲ组(玉米秸秆)。预试期7 d,正试期6 d。结果表明:小尾寒羊对Ⅰ组(苜蓿)的日均采食量为654.12 g,而采食率为68.75%,就采食量和采食率而言,与Ⅰ组(苜蓿)差异不显著,与Ⅲ组(玉米秸秆)差异显著(P<0.05),其高低顺序依次为Ⅰ组(苜蓿)>Ⅱ组(四翅滨藜)>Ⅲ组(玉米秸秆)。小尾寒羊对Ⅱ组(四翅滨藜)养分CP的消化率与Ⅰ组(苜蓿)差异显著(P<0.05),其它差异不显著;小尾寒羊对Ⅱ组(四翅滨藜)养分CP、EE、NFE的消化率差异极显著(P<0.01),P的消化率差异显著(P<0.05)。
