Growth response of broiler chickens to finisher diets containing high amounts of wheat bran

A Donkoh, CC Atuahene, M Dzineku


The study investigated the effect of including high amounts of wheat bran (WB) in finisher diets on growth performance and economy of gain of broiler chickens. The WB contained g kg-1 of dry matter, 894.3; crude protein, 193.5; ether extract, 42.1; crude fibre, 97.1; ash, 49.5; neutral detergent fibre, 503.8; acid detergent fibre, 167.2; hemicellulose, 336.6; Lignin, 29.3; starch, 197.0; and metabolizable energy of 6.72 MJ kg-1. In a feeding trial, four finisher diets containing maize, fishmeal, micro-ingredients and either 150, 250, 350 or 450 g of WB kg-1 diet and designated as dietary treatments WB150, WB250, WB350 and WB450, respectively, were fed ad libitum to 480 3-week-old commercial broiler chickens for 35 days. Birds had free access to water. As the dietary WB content was increased from 150 to 450 g kg-1, there was a significant (P< 0.01) increase in feed intake and a reduction in body weight gain and efficiency of feed utilization. The inclusion of high amounts of WB significantly influenced carcass dressing proportion and gizzard weight. However, there were neither health-related problems nor mortalities attributable to the amount of WB in the diet. There was a decrease in the cost of kg feed and feed cost kg-1 liveweight gain with increasing levels of dietary WB.
