摘要
文章旨在研究三丁酸甘油酯对青鱼生长性能、免疫性能和消化性能的影响。试验选择360尾初体质量为(12.47±0.69)g的青鱼幼鱼,随机分为4组,每组3个重复,每个重复30尾。4组青鱼幼鱼分别投喂添加0、500、1000、2000 mg/kg三丁酸甘油酯的等氮等脂试验饲料,试验为期8周。结果表明,饲料中添加1000和2000 mg/kg的三丁酸甘油酯显著提高青鱼的终末体重,显著降低饲料系数(P<0.05);添加量为2000 mg/kg时显著提升青鱼的肝体比。免疫性能方面,饲料中添加500 mg/kg三丁酸甘油酯可显著提高青鱼的超氧化物歧化酶含量(P<0.05);饲料中添加1000和2000 mg/kg三丁酸甘油酯可显著提高青鱼的溶菌酶和C3含量(P<0.05),饲料中添加三丁酸甘油酯对青鱼组织中碱性磷酸酶和C4无显著影响(P>0.05)。在消化性能方面,饲料中添加500 mg/kg三丁酸甘油酯可显著提高青鱼的超氧化物歧化酶含量(P<0.05);饲料中添加1000和2000 mg/kg三丁酸甘油酯显著提高青鱼的溶菌酶含量和C3含量(P<0.05),饲料中添加三丁酸甘油酯对青鱼组织中碱性磷酸酶和C4无显著影响(P>0.05)。总之,在青鱼饲料中添加一定比例的三丁酸甘油酯可有效提升青鱼生长性能,增强青鱼的免疫性能,促进青鱼的消化性能。在本试验条件下,三丁酸甘油酯最适添加量为1000 mg/kg。
The purpose of this study was to investigate the effects of tributylglycerol on the growth,immunity and digestibility of herring.360 juvenile herring with an initial body mass of(12.47±0.69)g were randomly divided into 4 groups with 3 replicates in each group(n=30).The four groups of juvenile herring were fed with equal nitrogen and equal fat diets supplemented with 0、500、1000 and 2000 mg/kg tributylglycerol respectively for 8 weeks.The results showed that the final body weight of herring was significantly increased and the feed coefficient was significantly decreased by adding glycerol tributylate 1000 and 2000 mg/kg(P<0.05),the liver/body ratio of herring was significantly increased when the addition of 2000 mg/kg.In terms of immune performance,the addition of 500mg/kg tributylglycerol significantly increased the content of superoxide dismutase of herring(P<0.05),the addition of 1000 and 2000 mg/kg tributylglycerol significantly increased the content of lysozyme and C3 of herring(P<0.05),but the addition of glycerol tributylate had no significant effect on alkaline phosphatase and C4 of herring tissue(P>0.05).In terms of digestibility,the addition of 500 mg/kg tributylglycerol significantly increased the content of superoxide dismutase of herring(P<0.05),the addition of 1000 and 2000 mg/kg tributylglycerol significantly increased the content of lysozyme and C3 of herring(P<0.05),the addition of glycerol tributylate had no significant effect on alkaline phosphatase and C4 of herring tissue(P>0.05).In a word,the addition of tributylglycerol in feed has a certain positive effect on the growth,immunity and digestibility of herring.Under the experimental conditions,the optimum addition of tributylglycerol is 1000 mg/kg.
