چکیده Coccidiosis is a common infectious disease in poultry, causing major economic losses. This research was conducted to investigate the effect of synbiotic Biomin®IMBO on resistance against coccidiosis in broiler chickens challenged with Eimeria. There were four dietary treatments in each experiment; basal diet (control), basal diet + 0.05, 0.1 or 0.15% synbiotic Biomin®IMBO of diet. One day-old male Ross 308 broiler chicks were divided into 16 cages (4 birds per cage) and were fed regular nonmedicated broiler diets. On 15d, chickens were inoculated esophageally with 5000 oocysts of either Eimeria acervulina (EA) or Eimeria tenella (ET). On 6 d postinoculation (dpi), intestinal lesion score and number of oocysts excreted for successive five days were determined. The results showed that lesion caused by EA and ET were significantly (P < 0.05) lower in birds fed diets with synbiotic especially at 0.1 or 0.15% levels (Table 3). Feeding synbiotic also significantly (P < 0.05) reduced oocyst shedding in infected birds. The rate of oocyst per gram feces (expressed as log10 x) was dose dependent so that birds fed diet containing 0.15% synbiotic had the lowest rate of oocyst shedding than the other groups in all days after inoculation of oocyst to birds. In conclusion, it can hypothesize that synbiotic Biomin®IMBO could have protective properties against coccidiosis in broiler diets.
