The use of antibiotics in poultry feed at therapeutic or subtherapeutic levels as well as bacterial resistance to antibiotics, which impedes human health, are causing growing public concern. To ensure animal health, productivity, and carcass quality, livestock farmers must be given alternatives to antibiotic growth promoters. The main objective of this study is to evaluate the effect of supplementation of plant source growth promoters (Garlic, Ginger, Neem and Moringa leaves meal) and their combinations, as Natural Growth Promoters in broiler chickens. A total of 360-day-old Cobb-500 broiler chickens were purchased from Olam hatchery, Chukum. The chicks were fed commercial diets for seven (7) days. Thereafter, the birds were randomly allotted to six (6) dietary treatments with four (4) replicates each, 15 birds per replicate. The rations were labeled as Diets: T1=basal diet + Antibiotics, T2=basal diet + Garlic, T3=basal diet + Ginger, T4=basal diet + Neem leaf meal, T5=basal diet + Moringa leaf meal and T6=basal diet + mixture of natural growth-promoter herbs. The data was analyzed by One-way analysis of variance (ANOVA) using R-studio application software, LSD was used to compare significant difference among the treatments means at P < 0.05. The results revealed that there were no significant (P > 0.05) differences among the dietary treatment means for daily feed intake, weight gain, and feed conversion ratio in all the three phases (starter, finisher, and overall). the results for carcass and organs characteristics revealed that there were no significant difference (P>0.05) among the treatment means for live weight, plucked weight, evisceration weight, carcass weight, head weight, shank weight, neck weight, thigh weight, breast weight, wing weight, dressing percentage. While a significant difference (P < 0.05) was shown on the leg weight and drumstick weight where diets T3 and T₂ were the highest. The weight of viscera organs; revealed a very high significant (p< 0.001) difference in kidney weight, and a high significance (p< 0.01) difference in spleen weight, Proventriculus weight, and small intestine weight, with a significant (p< 0.05) difference in lung weight. The results suggested that the natural herbal growth promoters are similar and had better output compared with commercial antibiotics growth promoters in most of the body cut parts. Therefore, these Natural Plant Growth Promoters will be used to replace Antibiotics Growth promoters without any adverse effects on broiler performance.
