Abstract

The experiment was conducted to determine the effect of mango (Mangifera indica) fruit reject meal (MFRM) on the carcass yield and blood profile of finisher broiler chickens.  The research was carried out at the Poultry house of the Livestock Unit, Teaching and Research Farm, University of Agriculture Makurdi. Day-old broiler chicks numbering 200, were grouped into five (5) with each group replicated four times and assigned to diets containing 0, 5, 10, 15 and 20% mango fruit reject meal (MFRM) as T1, T2, T3, T4, and T5 in a completely randomized design (CRD), and fed to finishing - 63 days. Carcass and blood profile were examined.  Results showed that fasted weight significantly reduced (P < 0.05), from 2025 to 1737.50g as MFRM increased (0-20%) in diets. Mean relative-dressed weight (60.57-63.09%) were not significantly different (p>0.05) across treatment groups. This trend subsisted for the main meat cuts and internal organs. White blood cell count (WBC) varied (p<0.05) without pattern, while red blood cell count (RBC) increased (p<0.05) as MFRM increased in the diets and both had values within normal ranges. Serum biochemical components were also not significantly different (p>0.05) across treatment groups.  It was concluded that MFRM has significant effect on fasted weight, decreasing it significantly at levels beyond 15% incorporation in broiler chicken diet. However, dressed weight, main meat cuts, internal organs and blood are not affected by inclusion of MFRM in broiler diets. It was recommended that 15% MFRM be included in broiler chicken diets to serve as an energy source.
