Insects, such as mealworm larvae, are promising sustainable protein sources due to their high reproductive ability, nutritional value, efficient organic matter conversion, cost-effective rearing, and minimal environmental impact. This study evaluates the nutritional composition and feed conversion efficiency of mealworm larvae reared on seven diets: W (100% wheat bran) as a control, A (50% wheat bran + 50% barley bran), B (75% wheat bran + 25% barley bran), C (50% wheat bran + 50% chickpea bran), D (75% wheat bran + 25% chickpea bran), E (50% wheat bran + 50% corn bran), and F (75% wheat bran + 25% corn bran). Results showed that diet C yielded the highest protein content and feed conversion efficiency, while diet B had the lowest. Fat content peaked in diets B and F. Variations in fiber, carbohydrates, ash, moisture, and minerals were also observed. Factors such as food intake, digestibility, and conversion ratios varied significantly among diets. The study highlights the critical role of dietary composition in optimizing mealworm larvae's nutritional profile and feed efficiency, offering a sustainable, cost-effective protein source for poultry and broilers. These findings support the strategic use of cereal brans to enhance feed quality, reduce costs, and improve scalability in insect farming, contributing to the sustainable production of animal protein.
昆虫，如黄粉虫幼虫，因其高繁殖能力、营养价值、高效的有机物转化、经济高效的饲养以及对环境的影响最小，而成为有前景的可持续蛋白质来源。本研究评估了以七种日粮饲养的黄粉虫幼虫的营养成分和饲料转化效率：W（100%麦麸）作为对照，A（50%麦麸 + 50%大麦麸），B（75%麦麸 + 25%大麦麸），C（50%麦麸 + 50%鹰嘴豆麸），D（75%麦麸 + 25%鹰嘴豆麸），E（50%麦麸 + 50%玉米麸），以及F（75%麦麸 + 25%玉米麸）。结果表明，日粮C产生的蛋白质含量和饲料转化效率最高，而日粮B最低。脂肪含量在日粮B和F中达到峰值。还观察到纤维、碳水化合物、灰分、水分和矿物质的变化。不同日粮之间的食物摄入量、消化率和转化率等因素存在显著差异。该研究强调了日粮组成在优化黄粉虫幼虫营养状况和饲料效率方面的关键作用，为家禽和肉鸡提供了一种可持续、经济高效的蛋白质来源。这些发现支持战略性地使用谷物麸皮来提高饲料质量、降低成本并提高昆虫养殖的可扩展性，有助于动物蛋白的可持续生产。
