This study aimed to examine the effect of supplementing moringa leaf meal on offal Mojosari ducks. This study used 60 female Mojosari ducks aged 3 weeks and used three different types of feed as treatments and one different type of feed as controls, with three replications for each treatment. The treatment with feed supplementation was P0 = 0% moringa leaf meal, P1 = 5% moringa leaf meal, P2 = 10% moringa leaf powder, and P3 = 15% moringa leaf meal. The parameters observed were offal, consisting of liver, heart, head, legs, feathers, and blood. The data obtained in this study were processed using analysis of variance and continued with the Duncan test. The results showed that the addition of moringa leaf powder had no effect (non-significant) (P > 0.05) on the offal of Mojosari ducks, namely the weight of the liver, heart, and feathers, while the weight of the head, legs, and blood showed a significant effect (P<0.05). Therefore, this study concluded that the addition of moringa leaf meal generally had an impact on the weight of the offal component of Mojosari ducks at the 15% level.
