摘要: 本试验通过研究伊犁夏牧场不同年龄、不同性别绵羊羊毛与血液中铁、铜、锰、锌、硒5种微量元素的含量及变化规律,为夏季放牧绵羊科学补饲微量元素提供依据。选择在新疆伊犁夏牧场卡拉卓恩(南坡)和唐布拉草地(北坡)1 400~2 999 m垂直带放牧的中国美利奴羊(新疆型)羊毛和血液样品,测定其铁、铜、锰、锌和硒含量,并评估其微量元素的营养生态环境。结果表明,放牧绵羊羊毛铁、铜、锰、锌和硒含量分别为520.70、3.89、30.16、102.64 mg/kg和41.18 μg/kg,其中铜和硒分别低于正常值48.3%和79.7%,而铁高于正常值603.4%;血液中铁、铜、锰、锌和硒含量分别为357.05、4.18、0.25、3.08 mg/L和45.23 μg/L,其中铜、硒分别低于正常值29.9%和73.9%,而铁高于正常值95.5%。羊毛与血液中铁、铜、锰、锌、硒含量均随年龄而增加。不同性别绵羊间血液中锌、硒含量差异明显。

Abstract: This experiment objective was to study the Fe, Cu, Mn, Zn, Se five kinds of trace element contents and change rule in the blood and wool of sheep pastured of different age and different gender, provide the basis for summer grazing sheep scientific supplementary feeding trace elements.At the altitudinal belt of 1 400 to 2 999 m of the summer pasture of the Karajon grassland (South slope) and Tangbula grassland (North slope) of Yili, Xinjiang, Chinese merino (Xinjiang type) sheep wool and sheep blood were collected, to determine their contents of Fe, Cu, Mn, Zn and Se for evaluating the nutritional-ecologic environment of trace elements of summer pasture of Yili.The results showed that the contents of Fe, Cu, Mn, Zn and Se in wool of grazing sheep wool were 520.70, 3.89, 30.16, 102.64 mg/kg and 41.18 μg/kg, respectively, in which the contents of the Cu and Se were lower than normal value by 48.3% and 79.9%, respectively, and that of Fe was higher by 603.4%.The contents of Fe, Cu, Mn, Zn and Se in blood were 357.05, 4.18, 0.25, 3.08 mg/L and 45.23 μg/L, respectively, in which the contents of the Cu and Se were lower than normal value by 29.9% and 73.9%, respectively, and that of Fe was higher by 95.5%.The contents of Fe, Cu, Mn, Zn and Se in the wool and blood were increased with the age.The blood contents of Zn and Se between male and female were extremely different.
