日粮添加芦荟多糖对断奶仔猪生长性能和血清生化指标的影响

摘要

为研究日粮中添加芦荟多糖对断奶仔猪生长性能和血清生化指标的影响，选取72头体重（7.29±0.52） kg杜×长×大断奶仔猪，按体重分为3个处理，每个处理4个重复，每个重复6头猪。对照组饲喂基础日粮（NC），试验1组猪为基础日粮+0.1%芦荟多糖（AVP1），试验2组为基础日粮+250 mg/kg 4%黄霉素（PC）。结果表明：与对照组相比，添加0.1%芦荟多糖可显著提高断奶仔猪平均日增重（ADG）（P＜0.01），显著降低料重比（F/G）（P＜0.05）；并能显著提高仔猪血清中总蛋白、白蛋白浓度和碱性磷酸酶活性（P＜0.05），降低尿素氮水平（P＜0.05）。结果说明，芦荟多糖可以改善断奶仔猪的生长性能，并且作用效果与黄霉素相近。%The experiment was conducted to study the effects of Aloe vera polysaccharide (AVP)on growth perfor-mance,serum biochemical indexes in weaned piglets.Seventy-two weaned piglets of (7.29 ± 0.52)kg body weight were randomly divided into three groups with four replicates of six each.The three groups were basal diet group (NC),basal di-et+0.1% AVP (AVP1),basal diet+250 mg/kg flavomycin (PC),respectively.The results showed as follows:Compared with control group,average daily gain (ADG)of AVP1 significantly increased (P < 0.01),the feed/gain of AVP1 significantly decreased (P < 0.05);the content of total protein and albumin and the activity of alkaline phosphatase (AKP) of AVP1 group significantly increased(P < 0.05),and the content of serum urea nitroge(SUN)significantly decreased(P < 0.05). The results indicated that AVP could improve growth performance of weaned piglets,and its effects was similar to flavomycin.
