Simple Summary: The European Union's poultry industry relies heavily on imported ingredients such as soybean meal. In this study, we tested three diets on 120 laying hens over 15 weeks: a soybean–corn diet, an alternative diet with locally sourced plant-based ingredients (peas, distillers' dried grains with solubles, and sunflower meal), and this alternative feed supplemented with 5% whole dried black soldier fly larvae. The results suggest that a novel alternative diet using fewer conventional ingredients could be developed into a flexible formulation that ensures productivity, sustainability, egg quality, and hen health. Given the significant environmental consequences of current poultry feed practices and the heavy dependence of the European Union on imported soybeans, studying alternatives is crucial. This study evaluated the potential benefits of using locally sourced alternative plant-based ingredients and whole dry black soldier fly larvae in the diet of laying hens. The experiment involved 120 Isazul hens at 23 weeks old, which were divided into three groups with five replicates each (eight hens per replicate): a control diet (CON) based on soybean meal and cereals, an alternative diet (ALT) replacing the soybean meal with locally sourced plant-based resources (peas, distillers' dried grains with solubles, and sunflower meal), and the ALT diet supplemented with 5% whole dry black soldier fly larvae (ALT+DBSFL). Over 15 weeks, the hens were fed ad libitum, and the production performance, egg quality, and plasma biochemical parameters were assessed across three experimental sub-periods. The results showed no significant differences in body weight, feed intake, egg production, egg weight, egg mass, or feed conversion ratio across the diets (p > 0.05). The egg quality remained consistent across all the groups; however, the hens fed the ALT+DBSFL diet exhibited higher Haugh units in the first experimental sub-period (p < 0.05) and lower plasma cholesterol and triglycerides at 32 weeks of age (p < 0.05). The findings of this study indicate that incorporating these alternative ingredients and whole DBSFL into layers' diets does not compromise production performance, egg quality, or biochemical parameters related to health status, supporting their potential as sustainable feed alternatives.
