摘要
【目的】本试验旨在研究饲粮中添加复方中药发酵粉对断奶仔猪生长性能、养分表观消化率、抗氧化功能以及免疫功能的影响。【方法】试验选取48头体重为(8.290±0.140)kg、健康状况良好的28日龄三元(杜×长×大)杂交去势断奶仔猪,按照体重随机分为2组,每组6个重复,每个重复4头猪。对照组饲喂基础饲粮,试验组饲喂基础饲粮+3%复方中药发酵粉,其中复方中药发酵粉由山楂、陈皮、鸡内金、山药、茯苓等原料发酵而成,其主要活性物质包括有机酸、黄酮类物质、多糖类及三萜类物质等。试验为期28 d,试验结束前3 d采集饲粮样和粪样,试验结束后每个重复选取1头接近平均体重的断奶仔猪进行屠宰,采集血浆和肝脏,测定生长性能、养分表观消化率、血浆和肝脏抗氧化指标、血浆免疫指标等。【结果】与对照组相比,复方中药发酵粉组断奶仔猪平均日采食量(ADFI)和料重比(F/G)均无显著差异(P>0.05),但其平均日增重(ADG)显著提高(P<0.05),腹泻率显著降低(P<0.05);粗脂肪(EE)、粗灰分(Ash)和钙(Ca)的表观消化率均极显著或显著提高(P<0.01;P<0.05);血浆过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GSH-Px)活性及总抗氧化能力(T-AOC)均显著或极显著提高(P<0.05;P<0.01),肝脏总超氧化物歧化酶(T-SOD)活性显著提高(P<0.05);血浆免疫球蛋白A(IgA)和免疫球蛋白M(IgM)含量均显著提高(P<0.05),肿瘤坏死因子-α(TNF-α)含量显著降低(P<0.05)。【结论】在饲粮中添加3%复方中药发酵粉可提高断奶仔猪对粗脂肪、粗灰分和钙的表观消化率,提高断奶仔猪机体的抗氧化功能和免疫功能,从而降低断奶仔猪腹泻率,提高其生长性能。
【Objective】This experiment was conducted to investigate the effects of compound Chinese medicine fermentation powder on growth performance,nutrient apparent digestibility,antioxidant function and immune function in weaned piglets.【Method】48 healthy crossbred and castrated weaned piglets(Duroc×Landrace×Yorkshire)of 28-day-old with similar initial body weight of(8.290±0.140)kg were randomly divided into 2 groups with 6 replicates per group and 4 pigs per replicate.Pigs in the control group were fed a basal diet,while the piglets in the experimental group was fed a basal diet containing 3%compound Chinese medicine fermentation powder.The compound Chinese medicine fermentation powder was fermented from Hawthorn,Tangerine peel,chicken’s gizzard-membrane,Chinese yam and Poria cocos,and its main active substances include organic acids,flavonoids,polysaccharides and triterpenoids.The trial lasted for 28 d,3 d before the end of the experiment,dietary and fecal samples were collected.At the end of the experiment,one weaned piglets with an average body weight were selected from each replicate for slaughter,plasma and liver were collected and growth performance,nutrient apparent digestibility,plasma and liver antioxidant indices and plasma immune indices were detected.【Result】Compared with the control group,there were no significant differences in the average daily feed intake(ADFI)and the feed to gain ratio(F/G)of weaned piglets in the compound Chinese medicine fermentation powder group(P>0.05),but the average daily gain(ADG)was significantly increased(P<0.05),and the diarrhea rate was significantly decreased(P<0.05).Compared with the control group,the apparent digestibility of ether extract(EE)and ash(Ash)and calcium(Ca)in the compound Chinese medicine fermentation powder group were extremely significantly or significantly increased(P<0.01;P<0.05).Compared with the control group,the plasma catalase(CAT)and glutathione peroxidase(GSH-Px)activities and the total antioxidant capacity(T-AOC)of weaned piglets i
