采用体质量-口罩法,分别在2、4、6、8、10、12月对天山北坡中段草地放牧的新疆细毛羊采食量进行测定,通过样方对牧草微量元素含量进行测定,计算放牧绵羊微量元素摄入量,另外不同季节绵羊发生周期性生理变化,对微量元素的需要量也不同,把不同季节放牧绵羊微量元素摄入量和需要量进行比较.研究结果得出不同季节绵羊从每天的采食中所获得的铁、锰、钴等微量元素能满足其需要.草地牧草中严重缺锌,母羊除在空怀期外其余时间锌缺乏量为16.0%~82.2%,特别是在母羊泌乳前期只能从牧草中获得需要量17.8%的锌.绵羊怀孕后期和泌乳前期缺铜55%和59%,常年缺硒6%~52%.

The daily trace mineral intake of grazing sheep was measured by gauze mask and mixed sample of edible forage which was made following the grazed ewes. Comparing with nutrition/nutrient requirements of sheep, daily intake of Fe, Mn, Co could meet the need of ewes and Zn was serious deficient (lacking up to 16%-82%) in grazed sheep except pregnancy in July and August, especially during the early lactation ewes only could get 17.8% from pasture. Daily intake by sheep could not get to a sufficient number of Cu and Se, the lack of Cu reached 55%-59% during the late pregnancy and early lactation, and the lack of Se reached 6%-52% during the whole year.
