Effects of Compound Fermentation of Traditional Chinese Medicine and Cyperus esculentus on Growth Performance,Serum Antioxidant and Immune Indexes in Hu Sheep
[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 increase d 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.
