Insects are promising candidates as alternative sustainable sources of protein for poultry species. The present research studied the effect of a dietary inclusion of a defatted black soldier fly (BSF) larvae meal as an alternative protein source in the diets of laying quails, on productive performance, egg physicochemical quality, fatty acid profile, sensory traits and storage stability. A total of 225 laying quails were divided into 3 dietary groups (5 replicates/each). A conventional soybean meal-based diet was formulated (Control group), and two other diets were formulated including either 10% (BSF10) or 15% (BSF15) defatted BSF larvae meal. Laying quails showed satisfactory productive performance throughout the trial. BSF10 and BSF15 eggs had the highest shape index ( < 0.01), shell weight and percentage ( < 0.001) and the most intense yolk color ( < 0.001). Defatted BSF larvae meal increased the eggs' saturated fatty acid content ( < 0.001) to the detriment of the polyunsaturated fraction ( < 0.001). Overall the eggs' sensory profile was not affected by the dietary treatment, but BSF15 eggs had a higher feed off-flavor Control group ( < 0.05). At day 28 of storage, oxidative stability was higher in BSF10 vs. Control eggs ( < 0.01). Defatted BSF larvae meal can be considered a possible alternative ingredient to soybean meal in laying quail diets, up to the 15% inclusion level.
昆虫有望成为家禽可持续蛋白质替代来源。本研究探讨了在产蛋鹌鹑日粮中添加脱脂黑水虻(BSF)幼虫粉作为替代蛋白质来源,对其生产性能、蛋的理化品质、脂肪酸谱、感官特性和储存稳定性的影响。总共225只产蛋鹌鹑被分为3个日粮组(每组5个重复)。配制了一种以传统豆粕为基础的日粮(对照组),以及另外两种分别含有10%(BSF10)或15%(BSF15)脱脂BSF幼虫粉的日粮。在整个试验过程中,产蛋鹌鹑表现出令人满意的生产性能。BSF10和BSF15组的蛋具有最高的形状指数(<0.01)、蛋壳重量和百分比(<0.001)以及最深的蛋黄颜色(<0.001)。脱脂BSF幼虫粉增加了蛋的饱和脂肪酸含量(<0.001),但不利于多不饱和脂肪酸部分(<0.001)。总体而言,日粮处理对蛋的感官特征没有影响,但BSF15组的蛋比对照组有更高的饲料异味(<0.05)。在储存第28天时,BSF10组蛋的氧化稳定性高于对照组(<0.01)。脱脂BSF幼虫粉可被视为产蛋鹌鹑日粮中豆粕的一种可能替代成分,添加水平可达15%。
