Soybean meal (SBM) is the most widely used plant feedstuff as a fish meal replacement (FM) in the aquaculture industry (El-Sayed, 1999). However, there are some nutritional concerns, such as the defective essential amino acid profile and the existence of several anti-nutritional compounds, in SBM (Francis et al., 2001). In addition to growth retardation and SBM-induced enteritis, poor nutrient utilization has also been documented in fish fed the SBM-containing diet (National Research Council (NRC), 2011; Lin & Cheng, 2017).For example, depression in lipid digestibility was heeded in fish that received the SBM-based diet (Lin & Cheng, 2017;Yaghoubi et al., 2016). This may be relative to the oligosaccharides and non-starch polysaccharides derived from SBM, those compounds may bind to bile salts, change the viscosity and passage rate of digesta or hinder digestive enzymes (Francis et al., 2001). Furthermore, taurine deficiency in SBM can depress bile synthesis and also interfere with lipid digestion and absorption Romarheim et al., 2008).
