“…Low‐lipid digestibility has been previously reported when SBM was included in the diets of rainbow trout (Watanabe, Pongmaneerat, Sato, & Takeuchi, ) and yellowtail (Nguyen et al, ). Alcohol‐soluble components in soy products affect lipid digestibility (Olli, Hjelmeland, & Krogdahl, ), and the removal of these components increases their digestibility in rainbow trout (Yamamoto et al, ) and yellowtail (Nguyen et al, ). Despite the fact that SPC is generally manufactured using aqueous alcohol extraction (Peisker, ), reduced lipid digestibility has still been reported when the level of SPC in feeds is increased (Mambrini, Roem, Carvedi, Lalles, & Kaushik, ; Ustaoglu & Rennert, ).…”
