中草药饲料添加剂对早期断奶仔猪血清抗氧化指标的影响

Effects of Chinese Herbal Additives on Serum Antioxidant Traits of Ablactation Piglets

采用完全随机化设计,选用96头(8±2d)断奶的长白×约克夏仔猪,随机分为4个组,分别在基础日粮中添加浓度为0%、0.1%、0.2%和0.4%的中草药添加剂,试验期为21d,研究中草药添加剂对血清免疫指标的影响。结果表明:中草药对仔猪的抗氧化作用在断奶后7d效果最好,降低了血清羟自由基和丙二醛的含量,分别是添加量为0.2%中草药组和0.1%中草药组最低,比对照组分别降低16.4%(p<0.05)和8.5%(p<0.05);提高了血清总抗氧化能力,添加0.2%中草药组的总抗氧化能力显著的高于对照组,提高幅度为31.0%(p<0.05)。断奶后14d,添加0.1%中草药组对羟自由基和总抗氧化能力作用最显著,与对照组比,降低羟自由基9.5%、提高总抗氧化能力22.8%(p<0.05)。到断奶后21d,各处理组差异不显著(p>0.05)。添加剂在断奶仔猪饲料中的最适添加浓度为0.1%。

Ninety-six crossbred（Landrace × Yorkshire） pigs（28±2） were assigned to 4 groups with 4 replications.Piglets in treatments were fed diets supplemented with 0,0.1%,0.2%,0.4% Chinese herbal additives respectively to study the effects of Chinese herbal additives on the serum antioxidant traits.The test lasted 21 days.The experiment showed that the dietary supplements of Chinese herbal increased antioxidation of pigs with best effect at 7th day after ablactation.0.2% and 0.1% Chinese herbal group decreased the content of serum hydroxyl radical and MDA by 16.4% and 8.5%（p0.05）.0.2% Chinese herbal group increased total antioxidant capacity by 31.0%（p0.05）.0.1% Chinese herbal group decreased the content of serum hydroxyl radical and increased total antioxidant capacity by 9.5% and higher 22.8% at 14th day after ablactation.（p0.05）.No difference was tested at 21st day after ablactation（p0.05）.Dietary supplement of 0.1% Chinese herbal medicine was the best.
