The inclusion of sustainable protein sources in poultry feed has become essential for improving animal welfare in livestock production. Black soldier fly larvae are a promising solution due to their high protein content and sustainable production. However, most research has focused on fast-growing poultry breeds, while the effects on native breeds, such as the Bianca di Saluzzo, are less explored. This study aimed to evaluate the impact of BSFL supplementation in the diet of slow-growing chickens, with a focus on growth, intestinal health and meat quality for final consumers.
The study demonstrated that Black soldier fly larvae supplementation, both in dehydrated and live form, improved growth performance, with an increase in final weights compared to the control group. No significant differences were found in feed conversion ratio, liver and spleen weight or histomorphometry between groups. Black soldier fly larvae supplementation did not negatively affect immune function or liver metabolism. Higher production propionic acid was detected in the black soldier fly larvae fed groups compared to the control, suggesting an effect on volatile fatty acid production. Gut microbiota analysis showed an increase in beneficial bacteria, such as Faecalibacterium, in the live larvae group. Furthermore, the meat fatty acid profile and atherogenicity and thrombogenicity indices did not undergo significant changes, implying a low potential risk to consumers' cardiovascular health.
Black soldier fly larvae supplementation in the diet of Bianca di Saluzzo improved growth without compromising animal health or meat quality. Moreover, the increase in beneficial volatile fatty acids and the modulation of gut microbiota suggest a positive impact on gut health. Finally, the absence of negative effects on meat lipid profiles confirms nutritional safety for consumers, making black soldier fly larvae a valid alternative in poultry feed. These results offer new perspectives for the use of Black soldier fly larvae in the nutrition of local breeds, contributing to sustainability in line with the One Health approach.
在家禽饲料中添加可持续的蛋白质来源对于改善畜牧生产中的动物福利至关重要。黑水虻幼虫因其高蛋白含量和可持续生产而成为一种有前景的解决方案。然而，大多数研究都集中在快速生长的家禽品种上，而对本地品种（如比安卡迪萨卢佐鸡）的影响研究较少。本研究旨在评估添加黑水虻幼虫对生长缓慢的鸡的日粮的影响，重点关注生长、肠道健康和最终消费者的肉质。
研究表明，添加脱水和活体形式的黑水虻幼虫均能改善生长性能，与对照组相比，最终体重有所增加。各组之间在饲料转化率、肝脏和脾脏重量或组织形态计量学方面未发现显著差异。添加黑水虻幼虫对免疫功能或肝脏代谢没有负面影响。与对照组相比，在喂食黑水虻幼虫的组中检测到更高的丙酸产量，表明对挥发性脂肪酸的产生有影响。肠道微生物群分析显示，活体幼虫组中的有益细菌（如粪杆菌）有所增加。此外，肉的脂肪酸谱以及致动脉粥样硬化性和血栓形成性指数没有发生显著变化，这意味着对消费者心血管健康的潜在风险较低。
在比安卡迪萨卢佐鸡的日粮中添加黑水虻幼虫可改善生长，而不会损害动物健康或肉质。此外，有益挥发性脂肪酸的增加和肠道微生物群的调节表明对肠道健康有积极影响。最后，对肉脂质谱没有负面影响证实了对消费者的营养安全性，使黑水虻幼虫成为家禽饲料中的有效替代品。这些结果为黑水虻幼虫在本地品种营养中的应用提供了新的视角，有助于按照“同一健康”方法实现可持续发展。
