牦牛缺硒病防治的研究

Research on the Prevention and Treatment of Se-Deficit Diseases in Yak

成年耗牛口服91.62μg/d释放剂量的硒丸,180d血硒分别为0.105±0.019,0.068±0.010μg/mL全血;378d血硒为0.103±0.056,0.058±0.019μg/mL全血。口服Se丸可有效地防治牛缺硒病,硒丸用于耗牛可减少死亡10.73％～14.73％,100％预防亚临床发病,提高产奶量23.7％。成年母牛服硒丸后,通过提高乳汁Se的排出,可100％预防哺乳犊牛缺硒病。

Se Pills of 91~62 ng/d was adminstrated to the adult yaks. After 180 days,Se in blood was 0. 105±0. 019 ug/mL and 0. 0681 ±0. 010 ug/mL in the whole blood respectively,and after 378 days,Se in blood was 0.103±0. 056 ug/mL and 0. 058 ±0. 019 ug/mL in the whole blood. Oral administration of Se pills can effectively prevent and treat the Se-deficit diseases in yaks. Se pills used in Yaks may also reduce the Yak death by 10. 73%~14. 73% ,and the sub-clinic incidence of Se-deficit disease will be completely controlled. Milk production cna be raised by 23. 7%. Also,after the adult female yaks were administrated with Se pills, the Se-deficit disease in baby yaks can be prevented and treated completely through the improvement of Se in milk in adult yaks.
