Abstract

The purpose of carrying out this research was mainly to determine the main effect of Parkia biglobosa leaf meal (PBLM) as a partial replacement for soybean meal in the broiler chicken diet. Five different diets were being formulated, with PBLM included at 0% (control), 5%, 10%, 15% and 20% designated to diet 1, 2, 3, 4 and 5 respectively. 150 day old broiler chicks were assigned randomly, on the basis of weight equalization, to the five dietary treatments with 30 broiler chicks for each treatment and 10 broiler chicks in each replicate. The experimental design used was completely randomized design (CRD). The experiment was conducted for a six weeks period. Three feeding phases were used in the experiment: which are starter phase (first 2 weeks), grower phase (third week) and finisher’s phase (the last three weeks). The proximate analysis of the PBLM, the effect of inclusion of PBLM on growth performance, carcass traits, haematological indices, serumbiochemical indices of the birds and the feed cost benefit of inclusion of PBLM in the experimental diets were determined. There was no significant (P0.05) effect on growth performance in broiler chickens fed up to 10% inclusion level of PBLM during the starter and grower feeding phases. The results for the growth performance at the finisher phase showed that the control diet and diet 2 are statistically similar for feed conversion ratio. This study also found that PBLM inclusion had no negative effects on the birds' viscera organs. The haematological and serum biochemical analyses of the broilers revealed no significant (P>0.05) effect on the birds. The study showed that the use of PBLM will reduce the cost of feed for broiler production. These findings indicated that Parkia biglobosa leaf meal could replace up to 5% of soybean meal in broiler diets without affecting animal health or carcass quality or blood parameters.
