Supplementation of Selenium-enriched Black Soldier Fly (Hermetia illucens) Larvae Meal on Growth Performance, Blood Parameters, and Immune Function in Broiler Ducks

This study aimed to evaluate the effects of Se-enriched Hermetia illucens larvae meal (Se-BSF) on production performance, blood biochemistry, and immune status of broiler ducks. Two hundred one-day-old hybrid broiler ducks without sex were randomly allocated into four groups, each with five replications of 10 ducklings. Broiler ducks were fed diets with a controlled diet, an experimental diet with 5% and 7.5% Se-BSF, and positive control with 10 mg/kg Se-Yeast, respectively, daily for 49 days with drinking water. The results showed that the performance production on the carcass traits and visceral organs of broiler ducks was significantly affected (P0.001) by Se-BSF supplementation. Dietary 7.5% Se-BSF showed trends in decreasing the feed intake, final body weight, average daily gain, and feed efficiency ratio. The effect of dietary Se-BSF was significant differences (P0.001) between all treatments in live body weight, carcass weight, dressing, breast meat, thigh meat, liver, and spleen. The addition of Se-BSF to broiler ducks’ diet showed no significant differences between all heart, gizzard, abdominal fat, and bursa treatments. The effects of dietary 5% to 7.5% Se-BSF had significantly affected (P0.001) HDL, LDL, Cholesterol, Triglyceride, Ig-A, SOD, and IL-6 levels in serum compared with control and 10 mg/kg yeast-Se. These results indicate that dietary Se-BSF improves broiler ducks' blood biochemistry and immune function, suggesting potential benefits from using Se-BSF as a feed additive for poultry.
