COMPARATIVE EFFICACY OF ANTIBACTERIAL PREPARATIONS IN PREVENTION OF BACTERIAL DISEASES IN BROILER CHICKEN FARMING

Abstract

This study was aimed at efficacy analysis of different non-conventional antibiotics in prevention of bacterial diseases in broiler chickens. Test for comparative analysis of efficacy of different antibacterial preparations in broiler chickens breeding was held at scientific and research center of Markinskaya Chicken Farm LLC in the Oktyabrsky District of the Rostov Oblast in November - December 2012 using Flavomycin, Basulifor, BIO+, bacteriocin, and cuprum sulphate. Ten groups of broiler chickens were enrolled into the test. Here are some results of the bacteriologic survey. Bacteriocin was the most effective in suppression of E. Coli. The least effective was probiotic preparation BIO+ at 200 g per ton. Probiotic preparation basulifor at 400 g per ton and bacteriocin were the most effective in suppression of Salmonella. The least effective was probiotic preparation BIO+ at 400 g per ton. Cuprum sulphate and probiotic preparation BIO+ at 200 g per ton were the most effective in Lb.spp bacteria preservation. Biacid was the least effective. Our test proved bacteriocin and probiotic preparation Basulifor at 200 g per ton the best preparations in terms of overall bacteriologic efficacy. The author found that efficacy of probiotic preparations and bacteriocin excelled antibiotics and other preparations.
