Abstract:
Abstract A total of one hundred and eight, one -day old, unsexed Hubbard F15 broiler breed chicks were used to investigate the effect of partial replacement of groundnut cake and vegetable oils by groundnut oil production waste (GOPW).Chicks were subjected to four rations groups in a completely randomized design with 27chicks for each group. Energy, protein efficiency ratio, production efficiency factor, liveability and mortality, rate, and some carcass characteristics were evaluated during rearing period of broiler chicken. Chicks were fed with experimental diets for 5 weeks (2, 3, 4, 5, and 6 week). The diets were as follow: 1) starter diet (8-28 d), 2) grower (29-42 d) which groundnut oil production waste entered by. The GOPW was included at 0%, 5%, 7.5%, and 10% in each diet. The diets were adjusted to be iso -nitrogenous and iso -caloric. It was observed that GOPW inclusion to replace groundnut cake and vegetable oils decreased the cost of production and improved some carcass characteristics when compared with chick group fed on control diet. However, The GOPW inclusion up to10% was non significantly reduced efficiency of energy utilization, protein efficiency ratio, production efficiency factor, and some carcass parameters of broiler chicken. However, it is concluded that groundnut oil industry waste can partially substitute till 10% of the broiler diets without any negative feedback and reduce the cost of production and can be used as alternative protein and energy source in poultry industry
