Effect of Dietary Inclusion of Probiotic, Prebiotic and Butyric Acid Glycerides on Resistance against Coccidiosis in Broiler Chickens

This research was conducted to investigate the effects of single or combined use of probiotic (Primalac), prebiotic (Fermacto) and butyric acid glycerides (Baby C4) compared to salinomycin on resistance against coccidiosis in broiler chickens challenged with Eimeria. One day-old male Ross 308 broiler chicks were divided into 9 cages with 15 birds per each. Birds of different treatments received a regular corn-soybean meal basal diet supplemented with feed additives; none of them in negative control (C-), salinomycin in positive control (C+), probiotic in PRO group, prebiotic in PRE group, butyric acid glycerides in BAG group, probiotic+prebiotic in PRO+PRE group, probiotic+butyric acid glycerides in PRO+BAG group, prebiotic+butyric acid glycerides in PRE+BAG group, and probiotic+prebiotic+butyric acid glycerides in PRO+PRE+BAG group. At 28 d of age, 8 birds from each treatment were removed and kept separately in other cages (2 birds/cage) to challenge with Eimeria. These separated chicks were orally challenged with 1×105 E. acervulina and 9×104 E. tenella. Positive effect (P
