The effect of Sulfaclozine 30% (ESB3) on experimental coccidiosis in broiler cockerels

To estimate the efficacy of sulfaclozine for control the experimental coccidosis in broiler chicks, 630 one-day-old male broiler chicks (Ross 308) were randomly divided in three treatments of 6 replicates. All chicks werc fed diet-based on com-soybean meal as starter, grower, and finisher (1-14, 15-28 and 29-42 days, respectively). Chicks in treatments 2 and 3 were inoculated with a mixed culture of foulʹ Eimeria species oocysts (including 2 x 10ʹ F, accrvuiina. 5 x I()ʹ !C. maxima, 2.5 x 10ʹ E. tenclta, and 2.5 x 10ʹ F, nccatrixt on 21 days of age. Chicks in treatment 3 received ESB3 by drinking water at a level 01ʹ2 gr/Lit on the age of 24-26 and 30-32 days, Fece samples were taken to determine the number of ooeysts excreted pelʹ gram of excreta (OPG) and Flock performance WQS determined. Infected birds with Eimeria oocysts had lower HWG, PEl and higher FCR (1ʹ<0.05), in comparison with non-infected chicks (negative control). Sulfaclozine 30% reduced the 01ʹ(; ofinfected birds and improved BWG, FCR and IʹLl (P
