| Research Abstract |
To investigate the effects of soybean meal on the bile physiology in rainbow trout Oncorhynchus mykiss, diets based on soybean meal (SBM) or fish meal (FM) were fed to trout for 10 weeks. In fish fed diet SBM, the expression levels of bile acid synthesis and bile acid transporter genes were lower than those of fish fed diet FM, which indicates that SBM suppress bile synthesis and its availability in rainbow trout.
