摘要/Abstract

摘要： 本试验旨在研究不同水平的复方中药对断奶獭兔生长性能、营养物质表观消化率、免疫功能及屠宰性能的影响.将70只60日龄断奶仔獭兔随机分为7组,每组5个重复,每个重复2只.Ⅰ组为空白对照组,饲喂基础日粮;Ⅱ组为抗生素对照组,饲喂在基础日粮中添加抗生素(含50 mg/kg杆菌肽锌、10 mg/kg硫酸黏杆菌素)的日粮;Ⅲ、Ⅳ、Ⅴ、Ⅵ、Ⅶ组为中药试验组,分别饲喂在基础日粮中添加1%、2%、3%、4%、5%复方中药的日粮.预试期7 d,正试期45 d.结果表明:①Ⅳ组平均日增重显著高于Ⅰ、Ⅱ、Ⅲ组(P< 0.05),料重比显著低于其他各试验组(P< 0.05).②在干物质表观消化率上,Ⅳ组显著高于Ⅰ、Ⅱ组(P< 0.05),Ⅶ组显著高于Ⅰ组 (P< 0.05);在粗纤维表观消化率上,Ⅳ组极显著高于Ⅰ组(P< 0.01),Ⅶ组显著高于Ⅰ组(P< 0.05);在中性洗涤纤维表观消化率上,Ⅳ组极显著高于Ⅰ组(P< 0.01),显著高于Ⅱ、Ⅲ、Ⅴ、Ⅶ组(P< 0.05);在酸性洗涤纤维表观消化率上,Ⅳ组显著高于Ⅰ、Ⅱ、Ⅴ、Ⅶ组(P< 0.05);在粗蛋白质表观消化率上,Ⅳ组显著高于Ⅰ、Ⅱ组(P< 0.05).③各试验组间免疫球蛋白(IgG、IgA、IgM)含量差异均不显著(P> 0.05);Ⅳ组脾脏指数显著高于Ⅰ、Ⅱ、Ⅲ、Ⅴ组(P< 0.05).④各试验组间屠宰率、半净膛屠宰率、全净膛屠宰率差异均不显著(P> 0.05).综上所述,日粮中添加复方中药和抗生素都可提高断奶獭兔生长性能、营养物质表观消化率、免疫功能及屠宰性能,且添加2%复方中药效果最好.

Abstract: This experiment was conducted to study the effects of different levels of compound Chinese medicine on growth performance,nutrients apparent digestibility,immune function and slaughter performance of weaning Rex rabbits.70 healthy Rex rabbits at age of 60 days were divided into 7 groups with 5 replicates per group and 2 rabbits per replicate.Group Ⅰ was fed with basic diet as control group,group Ⅱ was fed the basal diet supplemented with antibiotic (contains 50 mg/kg milligrams bacitracin zinc,10 mg/kg colistin sulfate).The other five groups (Ⅲ,Ⅳ,Ⅴ,Ⅵ and Ⅶ) were fed the basal diet supplemented with 1%,2%,3%,4%,5% compound Chinese medicine,respectively.The pre-test period lasted for 7 days and the trial period lasted for 45 days.The results showed as follows:①The ADG in group Ⅳ was significantly higher than that in groups Ⅰ,Ⅱ and Ⅲ (P< 0.05),the F/G in group Ⅳ was significantly lower than that in other groups (P< 0.05).②The apparent digestibility of DM in group Ⅳ was significantly higher than that in groups Ⅰand Ⅱ (P< 0.05),the apparent digestibility of DM in group Ⅶ was significantly higher than that in group Ⅰ (P< 0.05).The apparent digestibility of CF in group Ⅳ was extremely significantly higher than that in group Ⅰ (P< 0.01),the apparent digestibility of CF in group Ⅶ was significantly higher than that in group Ⅰ (P< 0.05).The apparent digestibility of NDF in group Ⅳ was extremely significantly higher than that in group Ⅰ (P< 0.01),and significantly higher than that in groups Ⅱ,Ⅲ,Ⅴ and Ⅶ (P< 0.05).The apparent digestibility of ADF in group Ⅳ was significantly higher than that in groups Ⅰ,Ⅱ,Ⅴ and Ⅶ (P< 0.05).The apparent digestibility of CP in group Ⅳ was significantly higher than that in groups Ⅰ and Ⅱ (P< 0.05).③ There were no significant differences in the contents of IgG,IgA and IgM of serum among all groups (P> 0.05),the spleen index in group Ⅳ was significantly higher than that in groups Ⅰ,Ⅱ,Ⅲ and Ⅴ (P< 0.05).④There were no significant differences in the slaughter rate,half eviscerated slaughter rate and all eviscerated slaughter rate among all groups (P> 0.05).In summary,adding compound Chinese medicine and antibiotics in the feed both could improve the growth performance,nutrients apparent digestibility,immune function and slaughter performance of weaning Rex rabbits,and the appropriate compound Chinese medicine level in the diet of weaning Rex rabbits was 2%.
