摘　　要：为了促进华池县科学养羊,测定了该县不同区域、不同海拔高度的土壤和舍饲下的绒山羊毛中的微量元素含量,并对其日粮现状、生产性能及健康状况进行了调查。结果表明,华池县土壤中Cu、Fe、Zn、Mn、Se5种元素含量低于全国平均值。Fe、Mn、Co、Ni、Cr元素丰盈,可满足动物生长需要。Cu、Zn、Se、I不足,Cd含量在安全范围内。建议山羊日粮中苜蓿（最大量）占50%-60%,玉米青贮或玉米秸秆20%-30%,玉米、麸皮等能量饲料18%-20%,CaHPO41.5%,并适量补充Cu、Zn、Se、I微量元素。To improve standards of raising goats in Huachi county,the contents of trace elements in soil and wool rearing in confinement were measured,and diet condition,performance traits,and health state were investigated.The results showed that the contents of Cu,Fe,Zn,Mn,Se in soil were lower than nationwide averages,respectively;the contents of Fe,Mn,Co,Ni,Ge were sufficient for animal growth;the contents of Cu,Zn,Se,I were insufficient,and the contents of Ge was on the safety scope.The result suggested that maximum of alfalfa in goat＇s diet be 50 ~60 percent;corn ensilage or straw account for 20~30 percent;energy feeds,such as corn and bran 18~20 percent,calcium hydrogen phosphate 1.5%;and trace element such as Cu,Zn,Se,I should be supplemented.
