Interpretive Summary:

Technical Abstract: The economic feasibility and risk of producing seven experimental tilapia diets on-site utilizing extrusion processing were analyzed. The experimental diets, which had been analyzed biologically at the Illinois State University Farm, contained varying quantities of soybean meal, corn, corn gluten meal, corn gluten feed, and distillers' dried grains as replacements for fish meal. One diet contained 32 percent crude protein, three contained 36 percent crude protein, and three contained 40 percent crude protein. Cost of gain was lowest for those diets which contained corn gluten feed and distillers' dried grains and highest for those diets which contained corn with corn gluten meal. Variability of cost of gain was greatest for those diets which contained corn with corn gluten meal. Sensitivity analysis revealed that the price of soybean meal was the most important source of variability in production costs for all diets. The labor wage rate was the most important non-ingredient source of cost variability. Results suggested that the risk of on-site diet production was unacceptable at 90,720 kg (100 tons) of annual production but acceptable at 544,320 kg (600 tons) of annual production.
