植物源氟对绵羊几种血清抗氧化酶的影响

以蒙古绵羊为试验动物,以乌梁素海高氟沉水水草龙须眼子菜(Potamogoton pectinatus)作为氟源,研究高氟水草对绵羊抗氧化系统及生产性能的影响。4组绵羊日粮水草氟水平分别为:0、50、100、150 mg/kg。连续饲喂5个月,观察绵羊中毒情况,测定绵羊15 d体质量增加量和血清抗氧化酶活性。结果表明,各试验组绵羊均未出现典型氟中毒症状;沉水水草与高丹草(Sorghum hybrid)对绵羊的体质量增加效果无明显差异(P0.05);血清超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活力均无显著变化(P0.05),血清总抗氧化能力(T-AOC)无显著变化(P0.05)。说明饲喂沉水水草后,绵羊生产性能未受到影响,机体的抗氧化系统未受到损害,没有发生氟中毒。

Effect of botanical fluorine on several serum antioxidase of sheep

An experiment was conducted to investigate the effect of botanical fluorine from Potamogoton pectinatus on ant oxidation system  and production performance of Mongolian sheep. Botanical fluorine with 0、50、100、150 mg/kg in daily ration was used to feed the Mongolian sheep for 5 months, and weight gain and serum antioxidase of Mongolian sheep was measured at the 15 days. This study indicated that Mongolian sheep was not found to be fluorosis toxicosis. The weight gain, serum superoxide dismutases, glutathione peroxidase, serum total antioxidant capacity were not different between Mongolian sheep fed with P.pectinatus and Mongolian sheep fed with Sorghum hybrid Sudangrass. This study suggested that P.pectinatus did not affect the production performance of Mongolian sheep.
