The Effects of Using Different Levels of Mannanoligosaccharides on the Performance, Carcass Characteristic and Blood Fat Profile of Broiler Chickens

A complete randomized experiment was conducted to study the effect of different levels of mannanoligosaccharides (0, 1, 2 and 3 g/kg into the basal diets) on growth performance, carcass characteristic and blood lipid profile in broiler chicks. Six hundred one day old Ross 308 broiler chicks were randomly assigned into 5 treatments. Each treatment consisted of 6 replicates and there were 20 chicks in each replicate. In this experiment, avilamicin antibiotic (10 mg/kg into the basal diet) was used as a positive control. The obtained in results starter period showed that, none of the growth performance parameters affected by adding prebiotic. Adding avilamicin also did not affect the parameters under study. By adding 2 and 3 g/kg prebiotic or avilamicin into basal diet weight gain improved as compared with control diet (P
