Abstrakt: The aim of the present study was to determine the nutritional value of black soldier fly (BSF) larvae meal for quail (experiment I) and the dose-response effects of BSF levels on growth performance, relative organ weight, and body composition of growing quails (experiment II). In experiment I, 100 35-day-old quail were distributed in a completely randomized design, with two treatments (reference and test diet) and 10 replicates. The experimental period consisted of 5 days of adaptation, followed by 5 days of total excreta collection. The experimental feed consisted of a reference diet and a test diet formulated with 850 g/kg reference diet and 150 g/kg BSF. In experiment II, 1000 1-day-old quail were distributed in a completely randomized design, with five dietary levels of BSF (0, 25, 50, 75, and 100 g/kg). At 42 days of age, birds were slaughtered, and the relative organ weight and body composition were determined. Apparent metabolizable energy values corrected for nitrogen retention of BSF meal were 13.8 MJ/kg. Across the starter (1-14 days) and overall period (1-42 days), increasing BSF levels had a quadratic effect on body weight and body weight gain. Feed conversion ratio was quadratically affected during the starter phase and linearly reduced over the overall period. Additionally, the BSF levels linearly decreased the small intestine's relative weight at 42 days and had a quadratic effect on the rate of protein deposition. We concluded that the inclusion of 100 g/kg BSF meal improves feed conversion ratio for growing quail.
