Effect of Dietary Selenium Conjugated Protein Black Soldier Fly Larvae Meal on Carcass Characteristics and Meat Fatty Acid Profiles in Broiler Duck

The study evaluated the effects of Se-conjugated protein black soldier fly larvae meal (Se-BSFL) on carcass characteristics and meat fatty acid profiles in broiler ducks. This study used a total of 200 one-day-old hybrid broiler ducks which were randomly divided into 4 treatment groups with 5 replicates, each replicate consisting of 10 ducks. The broiler ducks were fed with basal diet without Se-BSFL meal (0%), basal diet with 5% Se-BSFL meal, basal diet with 7.5% Se-BSFL meal, and basal diet with 10 mg/kg Se yeast. The results showed that feeding Se-BSFL with 7.5% and 10 mg/kg Se-Yeast significantly (p<0.05) decreased slaughter weight, carcass weight, breast yield, breast yield, breast percentage, thigh yield, and thigh percentage, but showed no significant difference in carcass percentage. The monounsaturated fatty acid profile of meat increased significantly (p<0.05) in line with the increase in Se-BSFL feeding level, but in contrast, the polyunsaturated fatty acid profile decreased significantly (p<0.05). In conclusion, feeding 5% Se-BSFL is recommended because it does not show a negative impact on carcass characteristics, especially a decrease in slaughter weight and carcass weight and shows the highest carcass percentage. Feeding Se-BSFL also had an impact on the monounsaturated and polyunsaturated fatty acid of broiler duck meat. These results indicate the potential use of Se-BSFL as a feed ingredient in poultry production although the use of high levels will reduce slaughter weight and carcass yield.
