Abstract
A seven-week study was conducted to determine the effect of mango fruit reject pulp-maize offal mix meal on growth performance, carcass characteristics, internal organs, gastrointestinal tract (GIT) morphometry, economics of production, flock uniformity and digestibility of nutrients by broiler chickens. Mango fruit reject pulp-maize offal mix meal partially replaced maize at 0, 5, 10, 15 and 20% in the diets of broiler chickens, respectively; represented as T1, T2, T3, T4, and T5 accordingly. One hundred and eighty (180) day-old Marshall broiler chicks were grouped into five, and each group was replicated three times while each replicate had 12 birds, in a Completely Randomized Design (CRD). The result of the feeding trial showed no significant difference (P >0.05) on growth performance parameters, digestibility of nutrients and economics of production. The Coefficient of Variation was less than 10. The carcass yield, internal organs and GIT morphometry all showed no significant difference (P >0.05). It was concluded that mango fruit reject pulp-maize offal mix meal can replace maize up to 20% in broiler chicken diet without negative influence on growth performance, nutrient digestibility, carcass yield, internal organs, flock uniformity and economics of production.
