Abstract

A 56-days feeding trial was conducted to investigate the nutrient digestibility and serum biochemical indices of grower pigs fed graded levels of rice offal supplemented with enzyme. Thirty (30) mixed local breeds of weaner pigs with an average of 7kg were sourced within Wukari. The pigs were divided into five dietary treatment groups of 6, replicated thrice with 2 animals per replicate in a completely randomized design. Five dietary treatments were compounded using Maize Offal (MO), Rice Offal (RO) and Brewers Dried Grain (BDG). Diet [1] serves as control with 100% maize offal, while diet 2 is a mixture of RO and BDG, diet 4 is BDG and finally diet 5 is RO. Diets 2-5 were supplemented with 0.2kg/100kg Quadraxyme. All parameters measured in nutrient digestibility were significantly different (P<0.05) while there was no significant difference in all parameters measured in serum biochemical. Also, the value obtained from this study was all within the normal ranges for pigs and can therefore be used by farmers for better results.
