摘要: 【目的】研究发酵中药和油莎豆复合物对湖羊生长性能、血清抗氧化及免疫指标的影响,为新型饲料添加剂的开发提供依据。【方法】选取体重相近、健康状况良好的育肥湖羊40只,随机分为2组:对照组和试验组,每组20只。对照组湖羊饲喂基础饲粮,试验组湖羊在基础饲粮中添加2%复合发酵物,预试期7 d,正试期42 d,在正试期第0、42天分别称重,计算平均日增重;记录日采食量,计算料重比;在试验第1、21和42天颈静脉采血并分离血清,测定湖羊血清中抗氧化指标和免疫指标。【结果】试验组湖羊的终末体重、平均日增重及平均日采食量均显著高于对照组(P<0.05)。与对照组相比,在试验第21天,试验组湖羊血清中过氧化氢酶(CAT)、总抗氧化能力(T-AOC)活性及免疫球蛋白G(IgG)、γ干扰素(INF-γ)含量分别提高了2.75%、3.46%、7.28%和4.55%(P<0.05),丙二醛(MDA)含量降低了12.72%(P<0.05);在试验第42天,CAT、T-AOC活性及IgG、INF-γ含量分别提高了3.17%、3.67%、9.77%和11.91%(P<0.05),MDA含量降低了15.10%(P<0.05)。【结论】在本试验条件下,饲粮中添加2%发酵中药和油莎豆复合物能有效改善湖羊的生长性能,提高抗氧化和免疫机能,可作为一种新型饲料添加剂应用到畜牧生产中。

Abstract: 【Objective】 This study was aimed to explore the effects of compound fermentation of traditional Chinese medicine and Cyperus esculentus meals on growth performance,serum antioxidant and immune indexes in Hu sheep,so as to provide a basis for the development of new feed additives.【Method】 Forty fattening Hu sheep with the same body weight and good health were randomly divided into 2 groups (control and experiment groups) with 20 sheep in each group.Hu sheep in control and experiment groups were fed with basal diet and added with 2% compound fermentation on the basal diet,respectively.The pre-test period was 7 days and the experiment period was 42 days.The body weight was weighed on the 0 and 42nd days of this experiment,and the average daily gain was calculated.Daily feed intake was recorded and feed to gain ratio was calculated.At the 1st,21st and 42nd days of this experiment,the blood samples were collected through the jugular vein,serum was separated,and serum antioxidant and immune indexes were measured.【Result】 The final body weight,average daily gain and average daily feed intake of Hu sheep in experiment group were significantly higher than those in control group (P<0.05).On the 21st day,compared with control group,the activities of catalase (CAT) and total antioxidant capacity (T-AOC),and the contents of immunoglobulin G (IgG) and γ-interferon (INF-γ) in serum of Hu sheep in experiment group were increased by 2.75%,3.46%,7.28% and 4.55% (P<0.05), respectively, the content of malondialdehyde (MDA) was decreased by 12.72% (P<0.05).On the 42nd day,compared with control group,the activities of CAT and T-AOC,and the contents of IgG and INF-γ in serum of Hu sheep in experiment group were increased by 3.17%,3.67%,9.77% and 11.91% (P<0.05),respectively,the content of MDA was decreased by 15.10% (P<0.05).【Conclusion】 Under the conditions of this experiment,the growth performance,antioxidant and immune function in Hu sheep could be improved effectively by adding 2% compound fermentation of Cyperus esculentus and traditional Chinese medicine in the diet,which could be used as a new feed additive in livestock production.
