The ban on the use of antibiotic growth promoter as feed additives in livestock has created a need for safer and more accessible antibiotic alternatives. One promising alternative is moringa (Moringa oleifera Lam.). Moringa leaves have the potential to serve as natural antibiotics that support digestive health and the function of visceral organs. This study aimed to analyze the performance of visceral organs following the administration of moringa leaf powder as a feed additive at various concentrations. Thirty female quails were divided into five treatment groups that received 0%, 2.5%, 5%, 7.5%, and 10% moringa leaf powder in their feed, with six replications per group. The quails were culled at 106 days, and their visceral organs including proventriculus, ventriculus, intestines, liver, pancreas, and heart were isolated and weighed. Data were analyzed using ANOVA at a 5% significance level. The results showed that moringa leaf powder supplementation significantly increased pancreatic weight, but did not produce significant differences in the weight of the other visceral organs. It can be concluded that the use of moringa leaf powder as a feed additive has a positive impact on increasing pancreatic weight and helps maintain the weight of the proventriculus, ventriculus, intestines, liver, and heart.
