Numerous advanced soybean meal (SBM) products are available in the market today, which were produced through modified or improved methodologies from the traditional solvent extraction procedure, to reduce or eliminate the antinutritional factors and improve bioavailability of nutrients. Despite the higher manufacturing cost, inclusion levels of these new SBM products into fish feed formulations can still be limited due to the secondary quality characteristics caused during processing. Hence, this study was designed to evaluate the effect of differently processed SBM, on growth performances of pacific white shrimps (Litopenaeus vannamei). The growth trial was conducted with test diets formulated with two sources of solvent‐extracted (SESBM44 and SESBM49), enzyme‐treated (ETSBM), fermented SBM (FSBM) and alcohol‐extracted soy protein concentrate (SPC) as the primary protein source (650 g/kg). As per the statistical analysis, diets incorporated with SESBM44, SESBM49 and ETSBM yielded a significantly higher growth performance and lower FCR. Results of this study infer that the traditional solvent‐extracted SBM perform equally well as enzyme‐treated SBM, whereas reduced performances of the shrimp offered fermented SBM and alcohol‐extracted soy protein concentrate might be due to reduced nutrient digestibility, palatability or other nutrient shifts caused by processing.

不同加工豆粕产品作为南美白对虾实用日粮成分的评价

当今市场上有许多高级豆粕 (SBM) 产品，它们是通过改进或改进传统溶剂提取程序的方法生产的，以减少或消除抗营养因子并提高营养素的生物利用度。尽管制造成本较高，但由于加工过程中产生的次要质量特性，这些新 SBM 产品在鱼饲料配方中的含量仍然受到限制。因此，本研究旨在评估不同加工的 SBM 对南美白对虾（Litopenaeus vannamei）生长性能的影响。生长试验使用由两种溶剂提取来源（SESBM44 和 SESBM49）、酶处理（ETSBM）、发酵 SBM (FSBM) 和酒精提取的大豆浓缩蛋白 (SPC) 作为主要蛋白质来源 (650 g/kg)。根据统计分析，添加了 SESBM44、SESBM49 和 ETSBM 的日粮产生了显着更高的生长性能和更低的 FCR。这项研究的结果推断，传统的溶剂提取的 SBM 与酶处理的 SBM 表现同样好，而提供发酵 SBM 和酒精提取的大豆浓缩蛋白的虾的性能降低可能是由于营养消化率、适口性或其他营养变化降低加工造成的。
