摘要

An 8-wk feeding trial was conducted using 320 broiler chicks of Arbor Acre strain to evaluate the effect of replacing maize with Palm Oil Mill Effluent (POME) with or without enzyme on the performance and carcass characteristics of broilers. Four diets were formulated in which POME replaced either 25% (diet 2), 50% (diet 3) or 75% (diet 4) maize in the control diet (diet 1). Each diet was fed to any of the eight groups of forty broiler chicks with or without Maxi grain enzyme in a 4 x 2 factorial experiment. Each experiment was replicated four times with each replicate consisting of 10 birds. Data were collected on feed intake, weight gain, feed conversion ratio, mortality, and nutrient utilization and carcass characteristics. Data were analyzed by two- way analysis of variance using General Linear Model procedure of SAS. Results revealed that live weight gain and feed conversion ratio were similar in birds that were fed 25% POME and control diet but these parameters were adversely affected in birds that received diets that contained 50% and 75% POME. Addition of Maxi grain enzyme improved the growth performance of the birds that received diet that contained 50% POME. Feed intake and livability were not adversely affected by the diets. Inclusion of POME in the diets decreased the utilization of dry matter and crude protein while fibre utilization was increased and ether extract unaffected. Addition of Maxi grain improved the utilization of all the nutrients considered except ether extract. Abdominal fat pad decreased with increased level of POME in the diets and was not affected by enzyme inclusion. Carcass yield and primal cuts were neither affected by POME inclusion nor enzyme supplementation. It was concluded from this study that POME can replace 25% maize in broiler diet but with Maxi grain enzyme supplementation it can be increased to 50%.
