This study aimed to determine the optimal inclusion level of protected sodium butyrate (PSB) in diets for during the postlarvae to grow-out phase. A completely randomized design was used with four dietary treatments: 0, 2, 4, and 8 kg/t of PSB (54% sodium butyrate). The PSB product (Novation SL 2002, Spain) contains 54% sodium butyrate protected by a physical and chemical matrix based on buffer salts. Growth performance, feed efficiency, survival, histological parameters of the intestine and hepatopancreas, and meat quality were evaluated. The results demonstrated that PSB supplementation significantly improved growth performance, feed conversion ratio (FCR), survival, and gut histomorphology, as well as enhanced meat production and quality. Based on the growth and feed efficiency responses, the optimal PSB inclusion level is recommended between 4 and 6 kg/t. Therefore, PSB is an effective dietary additive to improve productivity, gut health, and product quality in farming.
本研究旨在确定在幼体后期至养成阶段的饲料中，保护型丁酸钠（PSB）的最佳添加水平。采用完全随机设计，设置四种饲料处理：PSB添加量分别为0、2、4和8千克/吨（54%丁酸钠）。PSB产品（西班牙Novation SL 2002）含有54%丁酸钠，由基于缓冲盐的物理和化学基质保护。评估了生长性能、饲料效率、存活率、肠道和肝胰腺的组织学参数以及肉质。结果表明，添加PSB显著改善了生长性能、饲料转化率（FCR）、存活率和肠道组织形态，同时提高了肉产量和质量。基于生长和饲料效率反应，建议PSB的最佳添加水平为4至6千克/吨。因此，PSB是一种有效的饲料添加剂，可提高养殖中的生产力、肠道健康和产品质量。
