| 摘 要： | 为研究纳米硒对岢岚绒山羊妊娠母羊及胎儿抗氧化能力、硒蛋白表达和生长发育的影响。选择体重相近的岢岚妊娠绒山羊80只,随机分为2组,分别喂以基础日粮和添加0.5mg/kg DM纳米硒的饲粮,实验期110d。结果表明:日粮中纳米硒的添加极显著(P<0.01)地提高了母羊及胎儿血清中GSH-Px、SOD的活性;极显著(P<0.01)提高了母羊及胎儿肝、胎盘组织中GSH-Px、SOD的活性;极显著(P<0.01)降低了母羊及胎儿血清与胎盘组织中MDA的浓度。在日粮中添加纳米硒后,母羊及胎儿肝、肾组织中cGPx1 mRNA的表达显著提高(P<0.05);胎盘组织中的cGPx、SeP、Trx1 mRNA的表达极显著提高(P<0.01)。妊娠母羊的基础日粮中加入纳米硒,极显著(P<0.01)提高了妊娠母羊及胎儿血清、肝、胎盘组织中IGF-1的含量和IGF-1mRNA表达量,显著增加了胎盘、胎儿及胎儿肝、肾组织的重量(P<0.05)。日粮中添加0.5mg/kg DM纳米硒,增强了妊娠母羊及胎儿的抗氧化能力,提高了IGF-1、cGPx1、SeP和Trx1 mRNA的表达量,进一步促进了胎儿的生长发育。 |

| Abstract: | The study was conducted to investigate the effects of Nano-Se on antioxidation,selenoprotein expression, growth and development of pregnant cashmere goat and fetus in KeLan.A total of 80 pregnant cashmere goats in KeLan with approximately equal body weight were allotted to one of two experimental treatments,a control(C,n = 40) without supplemental Se in basal diet or supplemented(S,n =40) with nano-selenium(declared Se content 0.5 mg/kg DM). The whole feeding experiment lasted for 110 days.The results from ... |
