| 摘 要： | 为分析拉萨河谷冬春季放牧与舍饲彭波半细毛羊采食牧草、血液及被毛中主要矿物质元素的含量,试验选用1.5岁左右彭波半细毛羊母羊60只,随机分为放牧组(GZ)和舍饲组(IF)进行试验。结果表明:试验所用牧草矿物质元素,除钼外其他元素含量均为绿麦草>冬季天然牧草。冬季天然牧草磷、镁、硫、铜、锰、锌和硒及绿麦草镁含量低于正常范围。(2)舍饲组血清钙(P=0.026)、硫(P=0.030)、铜(P=0.011)和钼(P=0.014)含量高于放牧组,镁(P=0.090)、铁(P=0.071)、锌(P=0.083)和碘(P=0.066)含量有增高的趋势;其被毛钙(P=0.003)、磷(P=0.006)、镁(P<0.001)、铁(P=0.022)、锰(P<0.001)和碘(P=0.012)含量均高于后者,铜含量有增高的趋势(P=0.068)。在血液和被毛中,放牧组血清铜、锰及被毛铜、锰和硒含量及舍饲组血锰及被毛锰、硒含量均低于推荐值。以上结果表明,拉萨河谷冬春季放牧彭波半细毛羊钙、铁、钼和碘充足,但磷、镁、硫、铜、锰、锌和硒缺乏或不足;舍饲(以谷物为主的精补料+绿麦草干草)能有效解决磷、镁、硫、铜、锌和硒的缺乏问题,但锰仍需补充。
