This research aimed at improving the fatty acid (FA) profile of larvae (HI) and evaluating the effects of their inclusion in growing broiler quails' diets on the meat physicochemical quality, including detailed amino acid (AA) and FA profiles, sensory traits, and retail display. HI larvae were reared on two different substrates: layer mash (HI1) and 50:50 layer mash/fish offal (HI2). A total of 300 10-day-old quails were allocated to the three dietary groups (five replicates/each): a soybean meal-based diet was formulated (Control), and two other diets were formulated that included either 10% HI1 or HI2. Quails were fed the experimental diets until slaughter. Diets were formulated to be isonitrogenous and isoenergetic. Breast meat quality was affected by the dietary treatments, which displayed different proximate compositions and AA and FA profiles. Meat physical quality, sensory profile, and retail display remained unaffected for the most part. Overall, results showed that it is possible to improve the FA profile of the HI-fed quails' meat and thus lipid quality through substrate modulation of the HI's diet.
本研究旨在改善黑水虻幼虫（HI）的脂肪酸（FA）组成，并评估在生长中的肉仔鹌鹑日粮中添加HI对肉的理化品质的影响，包括详细的氨基酸（AA）和FA组成、感官特性以及零售展示效果。HI幼虫在两种不同的底物上饲养：蛋鸡混合料（HI1）和50:50的蛋鸡混合料/鱼杂（HI2）。总共300只10日龄的鹌鹑被分配到三个日粮组（每组五个重复）：配制了一种以豆粕为基础的日粮（对照组），另外两种日粮分别包含10%的HI1或HI2。鹌鹑饲喂实验日粮直至屠宰。日粮配制为等氮和等能量。胸肉品质受日粮处理的影响，不同日粮处理的胸肉具有不同的近似组成以及AA和FA组成。肉的物理品质、感官特性和零售展示效果在很大程度上未受影响。总体而言，结果表明，通过对HI日粮的底物调节，可以改善HI喂养的鹌鹑肉的FA组成，从而改善脂质品质。
