A 10-week feeding trial was conducted to evaluate the effects of partially substituting soya protein concentrate (SPC), with white lupin (Lupinus albus) meal in carp (Cyprinus carpio) diets. This study further investigated the dietary inclusion of a solid-state fermentation (SSF) product of Aspergillus niger in tandem with SPC replacement. Six experimental diets were produced to be isonitrogenous (42%), isolipdic (8%) and isoenergetic (19 MJ kg⁻¹). Four diets were formulated to have 12.5 and 25% substitution of SPC using lupin meal, and with and without a supplement of 0.1% of SSF. An additional two diets were designed to serve as a basal reference with no SPC replacement, but one supplemented with 0.1% SSF inclusion. The results of this study showed that SPC can be replaced with up to 25% white lupin meal in carp diets, without reduction of growth performance, feed utilisation, body composition, gut integrity or health. The addition of SSF to the test diets enhanced growth performance (specific growth rate, P < 0.05) and nutrient utilisation (e.g. feed conversion ratio and protein efficiency ratio, P < 0.05).

进行了为期10周的喂养试验，以评估用白羽扇豆（Lupinus albus）粕部分替代大豆浓缩蛋白（SPC）在鲤鱼（Cyprinus carpio）日粮中的效果。这项研究进一步研究了黑曲霉固态发酵（SSF）产品与SPC替代串联的饮食结构。产生了六种实验饮食，它们分别是等氮（42％），等脂（8％）和等能量（19 MJ kg ^-1）。使用羽扇豆粕，添加和不添加0.1％SSF的情况下，四种饮食的SPC取代度分别为12.5％和25％。设计了另外两种饮食作为基础参考，不替代SPC，但其中一种饮食补充了0.1％SSF含量。这项研究的结果表明，在鲤鱼日粮中，SPC可以替代高达25％的白羽扇豆粕，而不会降低生长性能，饲料利用率，身体组成，肠道完整性或健康状况。在试验日粮中添加SSF可以提高生长性能（比生长速率，P  <0.05）和养分利用率（例如饲料转化率和蛋白质效率比，P  <0.05）。
