UTILIZATION OF RICE OFFAL AS A RELPACEMENT FOR WHEAT OFFAL AS DIETARY FIBRE SOURCE BY BROILER CHICKENS

Résumé

An experiment was conducted to evaluate the response of broiler chickens to dietary levels of Rice offal as replacement to Wheat offal, using a completely randomized design, A total of three hundred (300) day-old Cobb 500 broiler chicks obtained from a commercial hatchery were used for the experiment. Feed and water were supplied ad lib and the trial lasted for 4 weeks. In the experiments. Rice offal replace Wheat offal as diet 1,2,3,4 and 5 respectively, as 0 (diet 1), 25 (diet 2), 50 (diet 3), 75 (diet 4), and (diet 5)100% levels. However, a synthetic enzyme, Roxazyme G, at 100g/kg feed was supplemented along with the offal. The Results showed no significant influence (P<0.05) of diet on initial weight, total weight, final weight gain and feed conversion ratio. However, performance traits significantly (P<0.05) differ among the diets on total feed intake, daily feed intake, daily weight gain and week 4 weight gain respectively. It was therefore concluded that Rice offal can replace Wheat offal with synthetic enzyme supplementation up to 100% level in broiler chicken diets without compromising performance.
