The present utility model discloses a feed composition for broiler chickens incorporating 5% mungbean (Vigna radiata) reject meal as a partial substitute for conventional protein sources. The composition includes corn, soybean meal, rice bran, vegetable oil, vitamin-mineral premix, limestone, salt, and amino acid supplements. Mungbean rejects are sun-dried and ground before blending into the feed. The technical problem addressed is the high cost of protein sources in poultry feed. This utility model provides a cost-effective, sustainable alternative by utilizing agricultural by-products. The formulation improves body weight gain, feed conversion efficiency, and profitability without adverse effects on meat quality or organ health. It is intended for use as starter or finisher feed in broiler production systems.
