Growth Indices and Cost Implications of Hybro Broiler Chicks Fed with Graded Levels of Fermented Wild Cocoyam Colocasia esculenta (L.) Schott Corm Meal as a Replacement for Maize

R. Olajide    

Abstract: Corms such as wild cocoyam [Colocasia esculenta] have potential to replace maize as a cheaper energy source in poultry rations. A feeding trial was conducted to evaluate the effects of graded levels of fermented wild cocoyam [Colocasia esculenta (L.) Schott] corm (FWCC), as substitutes for maize in the diets of broilers at the starter phase. One hundred and twenty unsexed day-old Hybro broiler chicks were randomly distributed to four dietary treatments in a Completely Randomized Design (CRD). There were 3 replicates per dietary treatment with 10 birds per replicate. Diet 1 without FWCC served as the control. Diets 2, 3 and 4 contained 10, 20 and 30% FWCC. Each of the diets represented a treatment. The experimental diets and clean drinking water were supplied ad libitum for 4 weeks (28 days) representing the starter phase of the broiler production. Result of the performance revealed significant (p<0.05) differences in feed intake, weight gain and feed conversion ratio. The economic analysis also showed that cost (58.52) of a kilogram feed was highest (p<0.05) for the control and least (53.10) for 30% FWCC. The least cost (101.24) of feed per kilogram weight gain (p<0.05) was obtained for birds fed 30% FWCC compared to (105.53) for the control. It was concluded that maize can economically be substituted with 30% FWCC in broiler starter diets.
