We evaluated the effects of full-fat black soldier fly larvae (BSFL) on broiler carcass composition, cut yield, and breast meat quality. Broilers were fed for 42 days with up to 20% dietary inclusion of BSFL (0, 5, 10, 15, and 20%). On day 42, 120 broilers were slaughtered, and images were taken using computed tomography. Breasts, drumsticks, and thighs were collected for cut yield determination. The pH, color, lipid oxidation, cooking loss, shear force, amino acid profile, and fatty acid profile of the breast meat were assessed. There was no dietary effect on carcass composition or meat quality parameters except for fatty and amino acids compositions. When 20% BSFL was included in the diet, individual fatty and amino acids, such as lauric and myristic acids, aspartic acid, glutamine, and lysine, increased by 22.0-, 5.50-, 1.08-, 1.06-, and 1.06-fold, respectively ( < 0.05). Although total polyunsaturated fatty acids decreased, eicosapentaenoic fatty acids (EPA) increased by 78% in the 20% BSFL inclusion group. In conclusion, up to 20%, dietary full-fat BSFL did not affect key meat characteristics but positively increased the levels of the health-claimable omega-3 fatty acid EPA.
我们评估了全脂黑水虻幼虫(BSFL)对肉鸡胴体组成、切块产量和胸肉品质的影响。用含有高达20% BSFL(0%、5%、10%、15%和20%)的日粮喂养肉鸡42天。在第42天,宰杀120只肉鸡,并用计算机断层扫描进行成像。收集鸡胸、鸡腿和大腿用于测定切块产量。评估胸肉的pH值、颜色、脂质氧化、蒸煮损失、剪切力、氨基酸谱和脂肪酸谱。除了脂肪酸和氨基酸组成外,日粮对胴体组成或肉质参数没有影响。当日粮中含有20%的BSFL时,个别脂肪酸和氨基酸,如月桂酸和肉豆蔻酸、天冬氨酸、谷氨酰胺和赖氨酸,分别增加了22.0倍、5.50倍、1.08倍、1.06倍和1.06倍(P<0.05)。虽然总多不饱和脂肪酸减少,但在20% BSFL添加组中,二十碳五烯酸(EPA)增加了78%。总之,日粮中高达20%的全脂BSFL不会影响关键肉品特性,但能积极提高具有健康声明的ω-3脂肪酸EPA的含量。
