This study evaluated the effects of incorporating biological silage from tambaqui (Colossoma macropomum) by-products (BST) on the performance, hematological and plasma biochemical parameters, and egg quality (physical, proximate composition and sensory characteristics) of older commercial hens. The BST was prepared by ensiling tambaqui by-products with lactic acid bacteria, cassava trimmings, and preservatives, producing a nutrient-rich, high-protein feed ingredient. One hundred and twenty Hisex Brown hens (83 weeks old) were divided into five treatment groups, each receiving diets with 0, 1, 2, 3, or 4% BST. Performance metrics, egg quality parameters, and blood samples were collected over 63 days. The results showed that diets with 1 to 2% BST improved egg weight, eggshell quality, and feed efficiency without adverse effects on hen health. However, higher BST inclusion levels led to declines in feed intake, egg production, and mineral content in eggs, possibly due to the sensory properties of the tambaqui-based diets. Hematological analysis indicated an increase in MCV and MCH values with higher BST levels, while triglycerides increased and cholesterol decreased, suggesting potential benefits for lipid metabolism at moderate inclusion levels. Sensory analysis of eggs showed greater acceptance in diets with 3% to 4% BST due to yolk color enhancement, although higher levels were not optimal for hen productivity. These findings support BST as a viable alternative feed in poultry diets, promoting waste utilization in a sustainable, circular economy model for the agribusiness sector.
本研究评估了添加来自 tambaqui（巨脂鲤）副产品的生物青贮饲料（BST）对老龄商品蛋鸡生产性能、血液学和血浆生化参数以及蛋品质（物理、近似成分和感官特性）的影响。BST 是通过将 tambaqui 副产品与乳酸菌、木薯残渣和防腐剂青贮制备而成，生产出一种营养丰富、高蛋白的饲料成分。120 只海赛克斯褐蛋鸡（83 周龄）被分为五个处理组，每组分别接受含 0%、1%、2%、3%或 4%BST 的日粮。在 63 天内收集生产性能指标、蛋品质参数和血样。结果表明，含 1%至 2%BST 的日粮可提高蛋重、蛋壳质量和饲料效率，且对母鸡健康无不良影响。然而，较高的 BST 添加水平导致采食量、产蛋量和蛋中的矿物质含量下降，这可能是由于基于 tambaqui 的日粮的感官特性所致。血液学分析表明，随着 BST 水平升高，平均红细胞体积（MCV）和平均红细胞血红蛋白含量（MCH）值增加，而甘油三酯升高，胆固醇降低，这表明在适度添加水平下对脂质代谢可能有益。对蛋的感官分析表明，由于蛋黄颜色加深，含 3%至 4%BST 的日粮中的蛋更易被接受，尽管较高水平对母鸡的生产性能并非最佳。这些发现支持 BST 作为家禽日粮中一种可行的替代饲料，在农业综合企业部门的可持续循环经济模式中促进废物利用。
