Preliminary evidence that cholesterol improves growth and feed intake of soybean meal-based diets in aquaria studies with juvenile channel catfish, Ictalurus punctatus

Two feeding trials were conducted in aquaria to examine the effects of dietary soybean meal (SBM), purified soybean saponin and supplemental cholesterol concentrations on growth responses of channel catfish. In the first experiment, five dietary treatments were formulated to contain either 0%, 13.9%, 27.7%, 41.6% or 55.5% SBM which was added to the diets at the expense of soy protein concentrate (SPC) on an isonitrogenous basis.
