Abstract

The aim of this study was to investigate the effects of feeding Azadirachtaindica leaf powder to broilers on their growth performance and apparent ileal digestibility in broilers. It may be because neem leaves have a variety of effects on intestinal micro flora, which protects it from stressful situations, that broiler chicks' body weight and weight gain increased when neem leaf powder was introduced to their diets. Both the control and neem leaf-fed broiler chicken groups consume considerably different amounts of feed. Its appetite- and digestion-stimulating, antibacterial, and hepatoprotective qualities, which assist to lower the microbial burden on birds and increase feed consumption, may account for the increased feed intake. The body weight, body weight gain, feed intake, and FCR across the treatment groups were found significantly higher (P< 0.05) compare to control. Thus, Neem leaf powder can be used in commercial broiler chicken diets as a natural, cost-effective feed addition to improve overall performance. It is concluded that adding 0.5% NLM to broiler diets will promote optimal performance and financial gain.
