We evaluated the addition of Hermetia illucens larvae (BSFL) fat to broiler diets compared to that of soybean oil (SO), rapeseed oil (RO), palm oil (PO), palm kernel fatty acid distillate (PKFD), poultry fat (PF), pig lard (PL), and beef tallow (BT) on performance, meat quality, and cecal microbiota abundance. BSFL addition reduced the feed conversion ratio compared to PO, PF, and BT addition and improved nutrient digestibility at 14 days and 28 days of age. BSFL addition enhanced broiler immune responses compared with SO, PO, and PL by increasing IgA levels; compared to PO by increasing IgG levels; and compared to PL by increasing IgY and IL-6 levels. Moreover, broiler free triiodothyronine levels increased when BSFL was added. Reduced drip loss after 7 days was observed in the RO, PO, PF, PL, and BT groups, while the salt-induced water uptake in the PL group was greater than that in the BSFL group. Compared with the SO group, BSFL addition increased C18:3 and overall n-3 FAs in breast meat. BSFL fat in broiler diets leads to outcomes that are more similar to those of plant oils than to those of animal fats, particularly regarding nutrient digestiblity and immune response.
我们评估了在肉鸡日粮中添加黑水虻幼虫(BSFL)脂肪与添加大豆油(SO)、菜籽油(RO)、棕榈油(PO)、棕榈仁脂肪酸馏出物(PKFD)、家禽脂肪(PF)、猪脂(PL)和牛脂(BT)相比,对肉鸡生产性能、肉质和盲肠微生物群丰度的影响。与添加PO、PF和BT相比,添加BSFL降低了饲料转化率,并提高了14日龄和28日龄时的养分消化率。与SO、PO和PL相比,添加BSFL通过提高IgA水平增强了肉鸡的免疫反应;与PO相比,通过提高IgG水平增强免疫反应;与PL相比,通过提高IgY和IL-6水平增强免疫反应。此外,添加BSFL时肉鸡的游离三碘甲状腺原氨酸水平升高。在RO、PO、PF、PL和BT组中观察到7天后滴水损失减少,而PL组中盐诱导的水分吸收大于BSFL组。与SO组相比,添加BSFL增加了胸肉中C18:3和总的n-3脂肪酸含量。在肉鸡日粮中添加BSFL脂肪所产生的结果与植物油更为相似,而非与动物脂肪相似,尤其是在养分消化率和免疫反应方面。
