Abstract

This study was conducted to evaluate the effect of graded levels of wheat offal diets supplemented with or without hemi-cell enzyme on dry matter intake and digestibility coefficient of broiler chickens. Two hundred and eighty eight (288) day old broiler chicks were allocated to eight dietary treatments (n=36/treatment) in a in a 4 x 2 factorial arrangement in a completely randomized design. The experiment involved the replacement of maize with wheat offal at four levels of inclusion 0, 10, 15, and 20, with or without hemi-cell enzyme supplementation. The result showed that dry matter intake and digestibility was higher on the wheat offal levels than the control. Broilers on 20% wheat offal and control diet had significantly (P<0.001) higher crude protein digestibility than 10 and 15% wheat offal levels. Crude fibre and ether extract digestibility were significantly higher on 20% wheat offal level than the other levels while NFE digestibility was higher on 10% wheat offal level. Hemi-cell® enzyme supplementation of wheat offal diets improved dry matter intake, crude protein digestibility, crude fibre digestibility and NFE digestibility. The enzyme supplemented wheat offal levels of 15 and 20% diets were better utilized leading to higher improvement in broiler performance in the experimental groups. The results of this study showed that hemi-cell® enzyme could improve performance, increase ileal nutrient digestibility with reduction in feed intake and higher profit, hence a reduction in feed cost.
