| 摘 要： | 为探讨苜蓿(Medicago sativa)皂甙对断奶仔猪生长性能和抗氧化性能的影响,选用72头体重7.5 kg左右的"杜×长×大"三元杂交断奶仔猪进行研究。试验随机分为4组:基础日粮组(C)、基础日粮添加0.5%苜蓿皂甙组(T1)、基础日粮添加1%苜蓿皂甙组(T2)和基础日粮添加2%苜蓿皂甙组(T3),每组3个重复,每个重复6头猪(公母各3头)。结果表明:苜蓿皂甙可以显著提高断奶仔猪的日增重(P<0.05),降低料重比,以T2组(1%苜蓿皂甙)效果最好;苜蓿皂甙可以显著提高断奶仔猪血清和组织中谷胱甘肽过氧化物酶(GSH-PX)和超氧化物歧化酶(SOD)的活性(P<0.05),降低丙二醛(MDA)的含量(P<0.05),而且随着苜蓿皂甙水平的增加,仔猪血清和组织中GSH-PX,SOD的活性呈升高趋势,MDA的含量呈下降趋势。因此,在断奶仔猪日粮中添加苜蓿皂甙可以提高其抗氧化能力,促进其生长。

| Abstract: | Experiments were conducted to determine effects of alfalfa saponins on growth performance and antioxidant properties in weaned piglets.Four dietary treatments were studied: control feed(C);control feed plus 0.5% alfalfa saponins(T1);control feed plus 1% alfalfa saponins(T2);and control feed plus 2% alfalfa saponins(T3).A total of 72 weaned piglets(Duroc×Landrace×Large white) were randomly assigned to four treatment groups by sex(three replicates per treatment with six pigs per replicate) and were fed for 30 days.Results show: alfalfa saponins significantly increased average daily gain of piglets(P<0.05).The feeding effect of piglets in T2 group(1% alfalfa saponins) was best with decreasing feed gain ratio;alfalfa saponins markedly increased glutathione peroxidase(GSH-PX) and superoxide dismutase(SOD) activities in serum and tissues of piglets(P<0.05);and significantly decreased malondialdehyde(MDA) content in serum and tissues(P<0.05).Moreover,GSH-PX and SOD activities increased while MDA content decreased with the increase of alfalfa saponins level.These findings suggest that the addition of alfalfa saponins can enhance antioxidant ability of piglets,as well as promote their growth. |
