摘要：The Wumeng semi-fine wool sheep industry is the pillar industry in the Wumeng mountainous area. In order to reduce the impact of overmuch or too little trace element nutrients on the Wumeng semi-fine wool sheep industry, we have carried out research on the effect of zinc on blood parameters of Wumeng semi-fine wool sheep in natural habitat. It was analyzed the contents of mineral nutrients in soil, forage and animal tissues and determined the blood physiological and biochemical parameters of Wumeng semi-fine wool sheep. The results showed that the zinc (Zn) content in the soil of the experimental pasture was significantly lower than that in the control pasture (P<0.01), and the Zn content in the forage of the experimental pasture was significantly lower than that in the control pasture (P<0.01); the Zn content in the blood of the experimental group was significantly lower than that in the control group (P<0.01), but there was no significant difference in other elements (P>0.05); the content of RBC, LY, NE in the blood of the experimental group was significantly lower than that in the control group (P<0.01); the activity of SOD,GSH-Px, CAT, AKP in serum of the experimental group was significantly lower than that in the control group (P<0.01), the content of MDA in serum of the experimental group was significantly higher than that in the control group (P<0.01), but there was no significant difference between the content of Hb, PCV, WBC, BUN and the activity of LDH, AST, ALT, γ-GT activity (P>0.05). So it can be seen that zinc deficiency in natural habitat has a significant effect on blood physiological and biochemical parameters of Wumeng semi-fine wool sheep, furthermore, it has very significant effect on antioxidant enzymes of the body.
