Effects of Mango (Mangifera indica) Leaf Powder Supplementation on Growth Performance and Carcass Characteristics of Broiler Chickens (Gallus gallus domesticus)

This study evaluated the effects of Mangifera indica (mango) leaf powder (MLP) on the growth performance and carcass characteristics of broiler chickens. A total of 90 ROSS 308 broiler chicks (male and female), aged 21 days, with an average weight of 783 ± 51 g (males) and 651 ± 39 g (females), were randomly assigned to three dietary treatment groups (T0: control, T1: 0.5% MLP, T2: 1% MLP) in a fully randomized design. Treatment started from 21 days of age to 49 days old. Live weight, average daily gain, and feed consumption were highest in chickens fed 1% MLP. Although feed conversion did not significantly differ across diets (P > 0.05), the 1% MLP group exhibited the best feed efficiency. Commercial carcass yield (CoCY) and conventional carcass yield (CvCY) were significantly higher in chickens fed 0.5% MLP, whereas the 1% MLP group showed superior growth performance. Regardless of diet, no significant differences (P > 0.05) were observed in pancreas weight. However, intestine density and liver percentage were significantly lower in chickens fed 1% MLP. This study suggests that Mangifera indica leaf powder supplementation can enhance broiler growth and carcass characteristics, with 1% MLP improving overall growth and 0.5% MLP optimizing commercial carcass yield.
