Effect of dietary prebiotic and organic acid on growth performance, carcass characteristics and intestinal morphology of broiler chickens

This research was conducted to investigate the effects of SAF Mannan prebiotic and Liptol HPA organic acid on performance¡ carcass traits and intestinal morphology of broiler chickens. In this experiment¡ 160 one-day-old Ross-308 broiler chicks were allocated to 4 treatments¡ 4 replications and 10 Chicks each by employing a completely randomized design for a period of 42 days. Experimental diets including: control diet (no additive) and diets containing 0.1% prebiotic¡ 0.1% organic acid and 0.1% mixed of prebiotic and organic acid. Feed intake (FI)¡ weight gain (WG) and feed conversion ratio (FCR) were determined periodically and carcass characteristics¡ productive index (PI) and intestinal morphology was measured at 42 days of age. Results indicated that¡ there were no significant differences between treatments in FI. The highest WG was observed for diet containing organic acid (P
