| 摘 要： | 旨在研究日粮硒水平对4~6月龄绒山羊生长性能和组织抗氧化能力的影响,为确定绒山羊羔羊日粮中适宜的硒供给量提供依据。选用体况良好、体质量接近的4月龄陕北白绒山羊羯羔羊24只,采用单因子随机区组设计分为4组,分别饲喂硒含量为0.11、0.21、0.41、0.61 mg/kg的4种试验日粮,试验期为60 d。结果表明:①日粮硒水平对绒山羊羔羊平均日增量无显著影响(P>0.05)。②肝脏和肌肉中的硒含量以及谷胱甘肽过氧化物酶(GSH-Px)活性随日粮硒含量的提高而升高。当日粮硒含量为0.11~0.41 mg/kg时,肝脏和肌肉组织中的硒含量以及GSH-Px活性均随日粮硒含量的升高而显著升高(P<0.05);当日粮中硒含量为0.41~0.61 mg/kg时,肝脏和肌肉组织中的硒含量以及GSH-Px活性不再随日粮硒水平的增大而继续显著增大(P>0.05);两种组织中的硒含量和GSH-Px活性之间存在高度正相关。③肝脏和肌肉组织中的丙二醛(MDA)含量随着日粮硒含量的提高而降低。当日粮硒含量为0.41~0.61 mg/kg时,肝脏和肌肉中MDA含量均保持较稳定水平。因此,4~6月龄绒山羊日粮中硒含量为0.41 mg/kg时...

| Abstract: | This trial was conducted to evaluate the effects of dietary selenium on growth performance and tissues antioxidant ability of 4 to 6 months old Cashmere goats,in order to determine the optimal dietary selenium level for kid Cashmere goats.24 wether and grown-well kid Shaanbei Cashmere goats with similar weight and age(4 months old) were assigned randomly into four treatments and fed respectively with four diets differed in selenium concentration(0.11,0.21,041,and 0.61 mg/kg) for 60 days.The results showed t... |
