Performance, Nutrient Utilization and Carcass Characteristics and Economic Impact of Broiler Chickens Fed Extruded Bakery Waste

Abstract: An experiment was carried out to evaluate the effects of replacing corn with extruded Bakery Waste (BWP) in a corn-soybean basal diet during the starter and finisher periods (day to 21 and 22-35 days of age, respectively) on the performance (weight gain, feed intake and feed conversion ratio), nutrient utilization (apparent nitrogen retention and nitrogen corrected apparent Metabolizable Energy (MEn)), carcass characteristics and cost of feed of broiler chickens. Six isocaloric and isonitrogenous diets were formulated using 0, 20, 40, 60, 80 and 100% of BWP. The levels of corn in the basal (0% BWP) starter and finisher diets were 53.7 and 62.78%, respectively. The replacement of dietary corn for up to 100% with BWP reduced costs of total feed and feed for the production of a kg live weight with no impairment on performance, nutrient utilization and carcass characteristics of broiler chickens. It is concluded that BWP can completely replace corn in broiler diets from day to 35 days of age. The substitution of corn with BWP offers economic benefits for both bakery and poultry producers.
