摘　　要：通过新疆5个羊场矿物质元素营养的研究，以了解新疆全年草场有关矿物元素的变化情况，缺乏程度及缺乏时间。研究表明：5个羊场中牧草含P量在秋草场至冬草场均表现缺乏。含Na量在塔城种羊场一年四季草场均缺乏，在阿勒泰二牧场冬、春、夏草场Na出现明显缺乏，而在秋草场又明显超出需要量；在巩乃斯种羊场春、夏草场明显缺乏，冬、牧草场又明显超量。5个羊场牧草含Se、Zn量的测定值明显低于需要量。而含Fe量在5个羊场中都不同程度地超过最高限量。牧草中元素Fe与Mn之间存在措抗作用；Mo、Cu比例少于1：4，绵羊体内仍表现缺Cu症。通过全面分析对比，初步确定在新疆5个种羊场天然草场上放牧的羊群，存在着P、Na、Zn、Mn、Se和Cu6种限制性矿物元素季节性营养紊乱现象。The nutritional Status of grazing sheep in Xinjiang were studied at five sheep farrns inthis Region. The research results indicated that at these five farms, P was insufficient onautumn and winter pasture, Na was insufficient on all seasonal pastures at Tacheng Studfarm. There was obvious inadequacy of Na on winter, spring and summer pasture, but ex-cessive on autumn pasture at No 2 Altai farm. Na was inadequate on spring and summerpasture, but excessive on winter and autumn pasture at Gongnaisi Stud farm. The contentsof Se and Zn were found less than requirements and the content of Fe was found above themaximum limitation more or less at the five farms. There was an interaction between Fe andMn in herbage. If the ratio of Mo and Cu is less than 1: 4, Cu defficient symptom in sheepcould be became obvious. Through comprehensive analyses and comparison, it is preliminar-ily concluded that there is seasonal mineral disorders of P, Na, Zn, Mn, Se and Cu whichlimit production of the grazing sheep on native pastures at the five farms in Xinjiang.
