复方中草药添加剂对稻鸭共作模式下成都麻鸭生理效应的影响研究

为研究复方中草药添加剂对稻鸭共作模式下成都麻鸭生长性能、血清生化指标、抗氧化指标及免疫指标的影响,试验选取体重相近、体况健康的15日龄成都麻鸭240只,随机分为4组,每组5个重复,每个重复12只。4组为对照组饲喂基础饲粮;试验1、2、3组在基础饲粮中按照质量比分别添加0.5%(低剂量组)、1%(中剂量组)、2%(高剂量组)的复方中草药,试验期90 d。结果显示:(1)试验1、2、3组的平均日增重分别较对照组提高2.19%、4.34%、4.98%(P<0.05);试验2、3组的料重比分别较对照组降低3.37%、3.63%(P<0.05);(2)试验2组和3组的总蛋白(TP)分别较对照组提高4.20%、6.08%(P<0.05);试验2组和3组的尿素氮(BUN)分别较对照组降低12.72%、16.36%(P<0.05);试验2组和3组的谷草转氨酶(ALT)分别较对照组降低15.84%、19.22%(P<0.05);试验3组的谷丙转氨酶(AST)较对照组降低19.34%(P<0.05);(3)试验2组和3组超氧化物歧化酶(SOD)分别较对照组提高15.80%、20.00%(P<0.05);试验3组的总抗氧化能力(T-AOC)较对照组提高22.37%(P<0.05);(4)三个试验组的IgA、IgM、IgG、IFN-γ、IL-2显著高于对照组(P<0.05),试验2组的肿瘤坏死因子-α(TNF-α)较对照组提高10.06%(P<0.05),试验2组和3的组溶菌酶(LZM)分别较对照组提高6.79%、5.66%(P<0.05)。综上,中草药添加剂能有效提高稻鸭共作模式下成都麻鸭的生长性能、血清生化指标、抗氧化指标及免疫指标,本试验条件下,最佳饲喂剂量为1%。

Effects of compound Chinese herbal medicine on physiological of Chengdu Sheldrake duck under integrated rice-duck farming mode

This study was designed to study the effects of compound Chinese herbal medicine on growth performance,biochemical index,antioxidant capacity and immune index of blood of Chengdu Sheldrake duck under integrated rice-duck farming mode.A total of 24015-day-old healthy Chengdu Sheldrake ducks with similar body weight were randomly allocated into 4 treatments with 5 replicates per treatment and 12 ducks per replicate.Group 4 was the control group,fed with basal diet.Groups 1,2,3 were experimental groups,were fed with a basic diet with additional 0.5%,1%,2%Chinese herbal medicine additive,respectively.The experimental period was 90 days.The results showed as follows:(1)Compared with control group,the average daily weight gain of experimental groups 1,2 and 3 were respectively increased by 2.19%,4.34%,4.98%(P<0.05);the ratio of feed-to-gain of the experimental groups 2 and 3 were respectively decreased by3.37%,3.63%(P<0.05).(2)Compared with control group,the total protein(TP)of group 2 and group 3 were respectively increased by 4.20%,6.08%(P<0.05);the blod urea nitrogen(BUN)of those were espectively decreased by 12.72%,16.36%(P<0.05);the aspartate aminotransferase(ALT)of those were espectively decreased by 15.84%,19.22%(P<0.05);the alanine aminotransferase(AST)of group 3 was decreased by 19.34%(P<0.05).(3)Compared with control group,the superoxide dismutase(SOD)of group 2 and group 3 were respectively increased by15.80%,20.00%(P<0.05),and total antioxidant capacity(T-AOC)of group 3 was increased by 22.37%(P<0.05);(4)Compared with control group,the contents of IgA,IgM,IgG,IFN-γand IL-2 of all experimental groups were significantly higher(P<0.05),the TNF-αof group 2 was increased by 10.06%(P<0.05);the LZM of group 2 and group 3 were respectively increased by 6.79%,5.66%(P<0.05).In summary,fedding with compound Chinese herbal medicine could increase the growth performance,biochemical index,antioxidant capacity and immune index of Chengdu Sheldrake duck under integrated rice-duck farming mode significantly.Under the experimental conditions,the optimum addition amount was 1%.
