Abstract

One hundred and fifty (150) Day old Anak cockerel chicks were used in this study, to evaluate the effect of feeding Sorghum Offal (SO) in the bird's performance, nutrient utilization and carcass characteristics. They were distributed into five dietary treatments, with varied levels of weight for weight replacement (2, 3, 4, and 5 contained 15, 35, 55 and 75 % sorghum offal in place of sorghum meal) respectively. While treatment 1 with zero replacement serving as control. The response of the birds, in terms of feed intake weight gained, feed conversion efficiency, and  apparent nutrient digestibility and retention were determined. The organ weights and weight of cut parts were also recorded. The result showed that weight of organs such as spleen, heart, liver, kidney and proventriculus increased significantly across the row. The study indicated that the substitution of sorghum offal for sorghum meal at levels up to 35 % can be tolerated by cockerel chicks.
