Abstract: Background and Objective: Chili pedicle meal, a byproduct of chili powder production, was evaluated for its nutrient quality in broiler feed. A trial was conducted to investigate the effects of chili pedicle meal on broiler chickens in terms of their growth performance, economic return and ammonia nitrogen levels. Materials and Methods: The study was conducted using 160 individual Ross 308 broilers at the age of 7-42 days. The animals were randomly distributed into four equal groups. Chili pedicle meal was added to the diets at different concentrations of 0, 0.5, 1.0 and 1.5% of the weight of diet, which corresponded to treatments T1, T2, T3 and T4, respectively. The growth performance, economic return and ammonia nitrogen were tested. Results: Body weight gain, average daily gain and fecal ammonia nitrogen decreased as the concentration of chili pedicle meal increased with no change in economic return. Conclusion: The chili pedicle meal administration decreased fecal ammonia nitrogen, which could be beneficial for broiler production. However, more studies are needed to detect the meat quality, sensory evaluations and mechanisms involved.
