摘要
类胡萝卜素是水产养殖中必需的膳食成分，广泛用于增强水生动物的色素沉着、提高应激耐受力和增强免疫反应。进行了为期 8 周的喂养试验，以评估不同膳食水平的玉米黄质 (Zea) 对南美白对虾生长性能、类胡萝卜素组成、抗氧化能力、肠道微生物群、生化参数和免疫生理反应的影响。总共 600 只幼鱼（初始体重：1.21 ± 0.12 克）喂食了五种含有增量玉米（0、50、100、200 和 400 毫克/千克饮食）的等氮和同脂实验饲料。结果表明，日粮中添加玉米可显着改善虾组织中的类胡萝卜素沉积。此外，虾体内类胡萝卜素水平的变化表现出显着的正相关性（P 0.05) with growth performance indicators, survival, feed conversion ratio, DHA deposition, hemato-immunological enzymes (alkaline phosphatase, lysozyme, acid phosphatase), antioxidant capacities (total antioxidant capacity and peroxidase), digestive enzymes activities, hypoxia tolerance response (LT50), and redness and yellowness parameters (a⁎and b⁎). While dietary Zea did not affect the total bacterial load, it significantly influenced intestinal microbiota diversity indices (Simpson, Shannon, and Chao) and relative abundance of dominant phyla, such as Proteobacteria. Furthermore, a comprehensive evaluation using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), combined with broken-line regression analysis, revealed that dietary Zea supplementation between 110.5 and 187.4 mg/kg diet resulted in distributed improvements across multiple parameters, including growth, antioxidant capacity, stress tolerance, enzyme activity, digestion, and body coloration. These findings highlight the potential of Zea as an alternative to traditional carotenoids in aquaculture. This study provides valuable insights into optimizing shrimp feed formulation, enhancing sustainability, and reducing production costs while maintaining high product quality.
