EFFECT OF USING DIFFERENT PERCENTAGES OF WASTE FROM RESTAURANTS AND FOOD FACTORIES ON THE PRODUCTIVE, PHYSIOLOGICAL, AND MICROBIAL CHARACTERISTICS OF BROILERS
To compare traditional broiler feed with unconventional feed, this study used restaurant and food factory wastes as broiler feed and how it affects their performance physiological and microbial features. 500 Lohman breed broilers were used in a 6 week experiment with a starting weight of 39 gm/bird and assigned to 5 treatments. Each treatment included four replicates with 25 birds in each. The treatments were T1 as a control, T2 with 25% food waste, T3 with 50% food waste, T4 with 75% food waste, and T5 with 100% food waste. The microbial count was performed at 15, 28, and 42 days of the experimental period. Average body weight, cumulative weight gain, and feed consumption at the end of the 6 weeks were the highest (p<0.05) for the T3 treatment (50% waste, 50% remaining) group. cumulative feed conversion factors were the best (p<0.05) for T1 and T3 reaching 1.56±0.04 and 1.61±0.02 grams of feed/gram of weight gain. Carcass weight was increased (p<0.05) with the T4 group. Birds’ abdominal fat was increased (p<0.05) in T5, while T1 had the lowest percentage of abdominal fat weight. In conclusion, certain grains in traditional broilers diets can be substituted with animal feed manufactured from food waste, which may positively affect resource conservation and pollution reduction.
