Effects of dietary soybean meal on the bile physiology in rainbow trout, Oncorhynchus mykiss

To clarify the effect of dietary soybean meal (SBM) on bile synthesis and enterohepatic circulation in rainbow trout, three isonitrogenous and isolipidic diets; a fishmeal based diet (diet FM), a SBM based non-fishmeal diet (diet SBM) and a 1% bile acid (taurocholate) supplemented SBM diet (diet C-tau) were prepared and acute/chronic effects of the diets on the bile physiology was examined. In the acute experiment (<24 h), fish fed the SBM based...
