ABSTRACT

This study was carried out to investigate the effects of tylosin (100 ppm) and salinomycin (60 ppm) and their combination in feed on some growth parameters in broilers chickens challenged with Clostridium perfringens which causing necrotic enteritis. Two hundred fifty one day old chickes were grouped into 5 groups: G1 non infected non treated (control group), G2 infected with Clostridium perfringens and non treated, G3 infected and treated with tylosin (100 ppm), G4 infected and treated with salinomycin (60 ppm), and G5 infected and treated with tylosin and salinomycin in combination. The results showed significant increase in body weight, body weight gain and feed consumption and showed significant improvement in feed conversion rate in chickens infected and treated with tylosin and salinomycin either alone or in combination when compared with chickens infected and non-treated. The results of this study provide evidence that tylosin phosphate (100 ppm.) and salinomycin (60 ppm), when administered in feed, are effective in the improving of the growth parameters (body weight, body weight gain, feed consumption, and feed conversion rate).
