Replacement Value of Normal Maize with Quality Protein Maize (Obatampa) in Broiler Diets

P.A. Onimisi, J.J. Omage, I.I. Dafwang and G.S. Bawa


Three hundred and sixty days old Ross Broiler Chicks were used in a completely randomized design feeding trial to evaluate the benefits of replacing Normal Maize (NM) with Quality Protein Maize (QPM) (Obatampa variety) in Broiler diets. There were 6 treatments of 3 replicates each and each replicate had 20 chicks. Six diets were formulated in which the NM in diet was replaced by QPM at 0, 25, 50, 75 and 100% representing T1, T2, T3, T4 AND T5, respectively while T6 was normal maize base diet balanced for lysine. The appropriate diets were fed to the birds for 4 weeks in the starter phase and 4 weeks in the finisher phase. At the starter phase, there was gradual numerical increase in weight gain as QPM increased in the diet. T5 was significantly better than T1-T4 but T6 was the overall best performance. Feed consumption was similar for T1-T5 but significantly higher for T6. Feed/gain ratio improved as QPM increased in the diet (p<0.05). Dressing % and weights of organs expressed as % of live weight and body parts expressed as % of dressed weight were not different statistically (p>0.05).
