The aim of the study was to investigate the effects of novel commonly available feed additives compared to avilamycin on the performance, E. coli, aerobic bacteria, yeast counts and some carcass traits of male broiler chickens. The control diet was supplemented with avilamycin, organic acid, prebiotic, plant extract and probiotic, respectively. Body weight, weight gain and the feed conversion ratio were significantly affected by dietary supplements throughout the experiment (P < 0.05). The chicks that received diets supplemented with avilamycin, prebiotic and plant extract had higher body weight and weight gain than those fed organic acid and probiotic supplemented diets. Avilamycin significantly improved feed conversion ratio compared to the control group, plant extract, organic acid, and probiotic treatments (P < 0.05). Prebiotic supplementation gave a similar feed conversion ratio to avilamycin (P > 0.05). In addition, the novel feed additives had better feed conversion ratio than the control group (P < 0.05) through the 0-6 week period. However, any significant differences among the groups were not found in terms of feed intake, carcass yields, coliforms, total aerobic bacteria, total yeast counts and intestinal traits (P > 0.05). In conclusion, novel feed additives improved body weight, weight gain and feed conversion ratio compared with the control group. Dietary avilamycin supplementation gave numerically higher results than diets containing either the novel feed additives or no supplementation (control) in terms of performance. © Verlag Eugen Ulmer, Stuttgart.
