Possibilities of using biscuit or wafer waste in broiler chicken diets.

Summary This study was conducted to investigate the dietary supplementation of efficiency biscuit and wafer wastes (BWW) on performance, carcass traits and some of blood biochemical parameters in broiler chickens. The present experiment was carried out in a completely randomized design (CRD) includes 144 one-day-old chicks fed experimental diets included 0, 8, 16 and 24% of BWW in 4 treatments and 3 replicates to 42 days of age. All experimental diets those supplemented with 8, 16 and 24% biscuit and wafer wastes had significantly more feed intake, but didn’t observe considerable differences for weight gain or feed conversion ratio (FCR). Dietary supplementation of different percent of biscuit and wafer waste couldn’t cause any significant difference for carcass traits. In serum biochemical measures, significant elevation of blood glucose was observed for groups supplemented with 16% or 24% biscuit-wafer wastes (P<0.01) in comparison with control or 8% supplemented groups, also total cholesterol and triglyceride were higher in biscuit supplemented groups. As conclusion, utilization of commercial biscuit and wafer wastes up to 24% of diet as corn replacement didn’t have any adverse effect on performance or carcass quality of broiler chickens. It was suggested that low cost rations can be formulated with utilization of biscuit or wafer wastes (up to 24%) in poultry diet when the price of corn is an expensive feed ingredient.
