Comparison of the effect of probiotic, prebiotic, salinomycin and vaccine in control of coccidiosis in broiler chickens.

Abstract

BACKGROUND: deformation and resistance to these drugs. AIMS: The aim of this study was to compare the effects of probiotic and prebiotic, that is used to boost digestive system health, with salinomycin and vaccine in controlling coccidiosis. METHODS: A completely randomized design, including 6 treatments, 4 replications and 20 birds in each experimental unit was applied. All experimental groups except negative control were challenged with suspension containing a mixture of three common species in Iran by oral inoculation in the crop at 28 days of age. RESULTS: ) compared to the positive control group (P<0.05). Also, in the intestinal tract injuries, there was a significant reduction between the vaccine and salinomycin compared to the positive control group only in the cecum section (P<0.05). The effect of treatments on performance index (PI) was investigated and it was found that the best performance between infected groups was for salinomycin and vaccine groups (P<0.05). CONCLUSION: Finally, it can be concluded that probiotic and prebiotic are not effective in controlling coccidiosis and its complications like vaccine and salinomycin.
