Abstract
The purpose was to investigate the feeding value of fibrous cocoa pod husk (CPH) either fermented with Pleurotus ostreatus or supplemented with fibre-degrading multi-enzymes (Viscozyme®L + Pectinex®5XL) before inclusion in diets for 3-week-old finishing broilers. Growth performance and carcass yield of broilers fed diets containing 100, 200 or 300 g kg−1 of the P. ostreatus-fermented CPH or 100, 200 or 300 g kg−1 of the enzyme-supplemented CPH as well as a normal broiler finisher diet (control), were investigated in a 35-day feeding trial setup as a completely randomised design, with the seven treatments replicated three times. There were significant differences (P < 0.05) among treatments for some of the parameters measured including growth-related indices, percent weights of abdominal fat, intestine, and gizzard. It was concluded that P. ostreatus-fermented dried CPH up to a level of 200 g kg−1 and enzyme-supplemented dried CPH up to a level of 100 g kg−1 could be included in broiler finisher diets without any deleterious effects.
