【摘要】 以犊牛为研究对象,研究刺五加对犊牛抗氧化机能的影响。选用7日龄中国黑白花公犊牛12头,随机分为4组,对照组为未添加组,试验组分别在鲜牛乳中添加2 g/kg刺五加粗粉、1 g/kg刺五加超微粉(UMPⅠ)1、g/kg刺五加化微粉(UMPⅡ),检测投喂后14,21,28 d犊牛血清和28 d犊牛肝脏中的超氧化物歧化酶(SOD)、丙二醛(MDA)及谷胱甘肽过氧化物酶(GSH-PX)活性。刺五加提高了犊牛肝脏和血清中SOD活性,降低了MDA的含量,对GSH-Px活性无显著影响。结果表明不同的刺五加加工产品都可增强犊牛抗氧化机能,其中刺五加化微粉的作用最为显著。更多还原

【Abstract】 This study was conducted to investigate antioxidative effect of Acanthopanax senticosus on calves.Twelve male offspring of Chinese Holstein Cattle(7 days old) were divided randomly into four groups consuming normal diet of fresh milk or normal diets supplemented with 2 g/kg coarse powder,1 g/kg UMPⅠ(Ultra-micro-powder produced by physical technology)or UMPⅡ(Ultra-micro-powder produced by physical chemistry technology) 1 g/kg of Acanthopanax senticosus,respectively. Superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) activities and Malondialdehyde(MDA) content were measured in serum on d 14,21 and 28 and liver on 28 d in calves.The results showed that SOD activity was increased and MDA content was decreased in serum and liver of calves.But Acanthopanax senticosus had no effect on GSH-PX activity in serum and liver of calves.This study indicated that different processing productions of Acanthopanax senticosus could differently enhance antioxidative function in calves,and efficiency of the UMPⅡ among these processing productions was the most significant.更多还原
