Fish fed these combinations had feed conversion values that did not differ significantly from fish meal containing diets. The corn/soy diets used in these studies did not adversely affect the flavor quality of the cooked fillets. Since feed costs represent over 40% of the production costs, use of less costly, more readily available protein sources should reduce or stabilize the cost of production. Based on an economic engineering model with a production of 90.3 metric tons per year, the cost of the experimental 3 corn coproducts/soybean meal tilapia diets ranged from $366-$384 per metric ton when these rations are processed on-site from locally available grains and grain coproducts. Our research demonstrates that it is both nutritionally and economically feasible to use an all-plant protein diet with corn-derived ethanol coproducts for feeding tilapia. |
