为研究微量元素营养舔砖对绵羊生化指标影响,提高养殖效益.该试验通过制作微量元素营养舔砖,对绵羊进行饲喂试验,选择10只健康绵羊分别采集羊饲喂前后的血液,测血清抗氧化指标及血清微量元素含量变化.试验结果表明:预制微量元素营养舔砖对Fe、Cu、Mn、Zn 4种微量元素具有较好的补充效果,对Se的补充效果较差.对绵羊血清中谷胱甘肽过氧化物酶(GSH-Px)活性、超氧化物歧化酶(SOD)活性及总抗氧化能力(T-AOC)有一定提高,丙二醛(MDA)含量所有降低.
In order to study the effect of trace element nutrient licking bricks on biochemical indicators of sheep and improve breeding efficiency.This experiment conducted feeding experiments on sheep by producing trace element nutrient licking bricks.Ten healthy sheep were selected and their blood samples were collected before and after feeding to measure serum antioxidant indicators and changes in serum trace element content.The experimental results show that prefabricated trace element nutrient licking bricks have good supplementation effects on the four trace elements of Fe,Cu,Mn,and Zn,but have poor supplementation effects on Se.The activity of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),and total antioxidant capacity(T-AOC)in sheep serum were significantly increased,while the content of malondialdehyde(MDA)was reduced.
