A six (6) week feeding trial was conducted to assess the effect of processed cassava flour and fresh blood labeled PCB on the growth performance of broiler chickens. Ninety (90) 2-week old broiler chickens were randomly selected in groups of 15 with mean initial liveweight of 276.6g per bird. Two iso-nitrogenous (19%) and iso-caloric (12.0 ME MJ/Kg) dietary treatments were tested: T1 (Maize + concentrate + wheat bran) and T2 (PCB + concentrate + wheat bran). Completely Randomized Design was used and dietary treatment was replicated thrice. There was no significant difference (P<0.05) in weight gain and final weight between birds fed T1 and T2. Birds fed maize-based diet (T1) showed higher (P<0.05) feed intake than their counterparts on PCB-based diet. However, the lower consumption of PCB-based diet did not affect their growth performance. Feed cost was reduced (P<0.05) when PCB was used. No mortality was recorded when PCB was fed to birds. There was no significance difference (P<0.05) in dressed weight, dressing percentage, leg weight and neck between birds fed T1 and T2. There was however significant difference (P<0.05) in gizzard weight, head weight and intestine weight between birds fed maize-based diet (T1) and PCB-based diet (T2). It was concluded that feeding PCB has favourable nutritional effect on growth performance of broilers and can serve as a substitute for maize in concentrate-based diet 2011-05-01T00:00:00Z http://41.74.91.244:8080/handle/123456789/4619 Development of feed package for layers using low energy agro-industrial by products Donkoh, A.; Zanu, H.Z. A feeding trial of 20 weeks duration was conducted using 240 point-of-lay Hy-line layers to study the nutritive value of diets containing low-energy agro-industrial by-products namely wheat bran, maize bran, rice bran, brewers’ spent grains and cocoa pod husk on laying performance. The experimental diets were formulated to be iso-caloric and iso-nitrogenous. They contained an average of 16.3% crude protein and metabolisable energy of 10.38 MJ/kg. Each dietary treatment was replicated four times in a completely randomized design. The initial average live weight of the experimental birds was 1.75 kg. Feed and water were provided ad libitum. Among the production parameters studied were feed intake, body weight gain, feed conversion ratio, hen-day production, hen-housed egg production, egg weight, mortality, shell thickness, and Haugh unit. In addition, cost-benefit analysis was carried out to establish the economic feasibility of the experimental diets. With the exception of feed intake which showed significant response (p < 0.05) to dietary treatments, all the other production parameters showed a nonsignificant positive response (p > 0.05). Cost per kilogram diet was reduced when agro-industrial byproducts were used. Dietary treatment T2 supported the best egg production with a net revenue of GH¢371.30. Seasonal increases in the prices of conventional feedstuffs like maize and fishmeal would make the use of agro-industrial by-products in poultry diets even more attractive. 2010-10-01T00:00:00Z http://41.74.91.244:8080/handle/123456789/1963 Development of feed package for layers using low energy agro-industrial by products Donkoh, A; Zanu, H.K A feeding trial of 20 weeks duration was conducted using 240 point-of-lay Hy-line layers to study the nutritive value of diets containing low-energy agro-industrial by-products namely wheat bran, maize bran, rice bran, brewers’ spent grains and cocoa pod husk on laying performance.
