Abstract
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.
