Utilization of Biscuit Waste in Poultry Diet- A Review

Abstract

Nowadays achieving sustainability and cost-effectiveness while providing sufficient nourishment for birds is a challenge faced by the poultry sector. Food waste is a global issue, involving fruits, vegetables, stale bread, pastries, biscuits, canned and baked foods, and expired dairy products. The surge in fast food and bakery consumption increases waste due to limited shelf life. These contributes to food wastage as well as pose disposal challenges and environmental concerns, which is a significant problem in a country like India where millions still lack access to adequate nutrition. Proper processing and management of bakery waste can reduce its burden by repurposing it as feed for monogastric animals like poultry. Among the bakery wastes, the biscuit waste typically incorporates carbohydrates, fats, and some protein making it a valuable ingredient for poultry feed. Biscuit waste can be utilized in feed formulations to supplement conventional ingredients through proper processing techniques like grinding, drying, pelletizing, and nutritional analysis. According to studies on poultry diets biscuit waste can save production costs, increase feed efficiency, and maintain or improve bird performance indicators including feed conversion ratio and weight gain. Utilizing biscuit waste for poultry feed helps to advance the circular economy principles by keeping waste out of landfills and lowering the environmental impact of the food and poultry industries. Overall, using biscuit waste into chicken feed can improve sustainability, resource efficiency, and economic viability by lowering food waste, preserving resources, minimizing the impact on the environment, and cutting production costs.
