Study on the Application Effects of Rabbit Coccidiosis Recombinant Protein Yolk Antibody Combined with Functional Additives
In this study,25035-day-old weaned New Zealand meat rabbits with similar body weight were random-ly divided into 5 groups:control group,experimental group 1,2,3 and 4.The control group was supplemented with Es-gap,Em-gm and Ei-ama yolk antibody(each accounts for one-third)1 g/kg.Groups 1,2 and 3 were supple-mented with Shanhuasu 0.5 g/kg,Clostridium butyricum 0.2 g/kg and benzoic acid 2 g/kg on the basis of the above three kinds of compound yolk antibody 1g/kg,and group 4 were supplemented with compound yolk antibody 1 g/kg,Shanhuasu 0.5 g/kg,Clostridium butyricum 0.2 g/kg and benzoate 2 g/kg.There were 5 replicates in each group and 10 rats in each replicate,and 42 days of age of artificial infected insect attack.The results showed that the average daily gain,daily feed intake and survival rate of group 4 were significantly higher than those of other groups(P<0.05),and the ratio of feed to meat was significantly lower than that of other groups(P<0.05).The cri-teria of ACI value were as follows:the control group,test groups 1,2 and 3 had good anticoccidial effect,and the test group 4 had excellent anticoccidial effect.Conclusion:the combination of Es-gap,Em-gm and Ei-ama yolk antibody combined with Shanhuasu,Clostridium butyrate and benzoic acid can significantly improve the produc-tion performance and reduce the number of oocysts in young rabbits.ACI value judgment standard for its excellent ball insect resistant effect.
