摘　　要：文章为了探明饲粮补饲苦荞黄酮对断奶仔猪的生长、消化性能及血液生理生化指标的影响,进行了试验。该试验选取体重和日龄均相近的断奶仔猪32头,随机分为4组,每组8个重复。对照组(CON)在基础饲粮中添加40 mg/kg硫酸黏杆菌素;试验组(BF20、BF40、BF60)在基础饲粮中补充20、40、60 mg/kg苦荞黄酮(有效含量70%),试验期35 d。结果表明:1)BF40、BF60组仔猪采食量和日增重显著高于BF20组(P<0.05);2)BF60组仔猪饲粮总能、干物质、有机物的消化率显著低于BF20组(P<0.05);3)BF40组仔猪血清GH显著高于BF20组和CON组(P<0.05)、血清TAOC、SOD、GSH-Px和CAT含量显著高于其他3组(P<0.05),MDA显著低于其他3组(P<0.05);BF60组仔猪血清NEFA、IGF-Ⅰ、IgA、IgG含量显著高于其他3组(P<0.05)。综上所述,苦荞黄酮能改善断奶仔猪生长性能、免疫功能及抗氧化能力。建议苦荞黄酮添加量为40 mg/kg。This study was conducted to investigate the effect of buckwheat flavones on the growth performance,nutrient digestibility and serum indices of weaned piglets.A total of 32 healthy weaned piglets with similar age and body weight were randomly divided into 4 groups with 8 replicates in each group.Piglets in control group(CON)were fed with a basal diet supplemented with 40 mg/kg colistin sulfate,and those in other three groups(BF20,BF40,BF60)were fed with basal diet supplemented with 20,40 and 60 mg/kg buckwheat fl avones,respectively.The experiment lasted 35 days.The results showed that:1)The average daily feed intake and average daily gain of piglets in BF40 and BF60 were higher than those in BF20 and CON group(P<0.05).2)The digestibility of dietary total energy,dry matter,organic matter,and rude protein in BF60 were lower than those in CON group(P<0.05).3)The serum GH content in BF40 was higher than that in BF20 and CON groups(P<0.05).The serum TAOC,SOD,GSH-Px,and CAT contents in BF40 were higher than other groups(P<0.05),but the MDA content was lower than other groups(P<0.05).The serum NEFA,IFG-1,IgA,and IgM content in BF60 were higher than other groups(P<0.05).In conclusion,buckwheat fl avones can improve the growth performance,immune function and antioxidant capacity of weaned piglets.The recommended dosage is 40 mg/kg.
