| 摘 要： | 为了评价施肥对牧草矿物元素含量和牦牛铜代谢的影响,在黄河首曲草地进行施肥试验、放牧试验和动物矿物元素补充试验.结果表明:施肥明显增加了牧草N的含量(P<0.01),但各施肥处理之间没有明显的差异.(NH4)2SO4施肥明显增加了牧草S的含量(P<0.01).试验结束时(NH4)2SO4施肥牧场的牦牛血液和肝脏铜(Cu)含量极显著低于(P<0.01)NH4NO3施肥牧场和对照牧场,同时(NH4)2SO4施肥牧场的牦牛出现小红细胞贫血.肝脏Cu含量最低的10头牦牛接受Cu补充,在整个试验过程中接受Cu补充的牦牛肝脏和血液的Cu含量都在升高.试验结束时,补充CuClO(OH)3的牦牛肝脏铜含量极明显高于(P<0.01)补充CuSO4的牦牛,但血液铜蓝蛋白(Cp)含量没有显著的差异 .

| Abstract: | To assess the impact of nitrogen(N) fertilization on concentrations of mineral in herbage and copper metabolism in grazing yaks,the fertilizing experiment,the grazing experiment and the supplementing mineral experiment were conducted in the Huanghe Shouqu grassland.In the fertilizing experiment,the results showed that the mean S concentration in forage from pasture fertilized with ammonium sulfate was significantly higher(P<0.01) than yaks from pasture fertilized with ammonium nitrate and control.The mean c... |
