摘要
为研究益生菌发酵豆粕抗氧化活性和对尖吻鲈生长性能、饲料效率的影响,以豆粕和发酵豆粕的水提物、醇提物为试验对象,测定其DPPH自由基的清除率;将发酵豆粕分别以0%(对照组)、0.5%、1.25%、2.5%添加至尖吻鲈饲料,每组5个重复,每个重复10尾尖吻鲈鱼苗,采用自然光照,温度保持在26.5—30.5℃,每天两次(9:00和18:00)饲喂至饱食,共饲养12周。结果显示:发酵豆粕的水提物和醇提物的DPPH清除率优于豆粕;各添加组的增重率、饲料系数、肝体比和肌肉脂肪含量结果均优于对照组,且以2.5%的添加量为最优。
This study aimed to evaluate the antioxidant activity of water and alcohol extracts of soybean meal and fermented soybean meal,and its efffects on growth performance and feed efficiency of Lates calcarifere.For animal experiments,Lates calcarifer in 4 groups were fed the basal diet supplement with 0%(control group),0.5%,1.25%,and 2.5%fermented soybean meal,with 5 replicates per group and 10 fish per replicate.Natural light was used in feeding environment and the temperature was kept at 25~40℃,feeding twice daily(9:00 and 18:00)until full for 12 weeks.The results showed that DPPH scavenging rate of water extract and alcohol extract of fermented soybean meal was better than that of soybean meal(P<0.05).The weight gain rate,feedgain ratio,hepatosmatic index,and meatfat ratio of dietary supplement with fermented soybean meal group were better than those of the control group,and 2.5%group was the best.
