This study was conducted to evaluate the effect of black soldier fly larvae (BSFL) as a source of protein in layer diets on product performance, egg quality, hatchability, fertility, and sensory characteristics of eggs. The BSFL contained a high percentage of protein (559.9 g kg−1), metabolizable energy (696.3 kcal kg−1), crude fat (18.6 g kg−1), and dry matter (178 g kg−1) and a good balance of amino acids. A total of 54 Arabic strain hens at nine months of age […]

The aim of this study was to determine the dietary protein requirement and associated energy to protein (E/P) ratio for “Piracanjuba”, Brycon orbignyanus, fingerlings. Casein-gelatin semipurified diets were formulated to contain six crude protein (CP) concentrations: 24, 26, 29, 32, 36 e 42% at one energy level, 3,000 kcal metabolizable energy (ME)/kg. These diets resulted in E/P ratios of 12.3, 11.6, 10.4, 9.2, 8.5 and 7.1 kcal ME/g CP, respectively. The protein, lipid and digestible carbohydrate sources were casein/gelatin, cod […]
