A study conducted in Hungary evaluates the suitability of corn distiller’s dried grains as protein source for European catfish

An abundant but underutilized ingredient may be used as a suitable partial replacement to the more expensive traditional grains in European catfish (Silurus glanis) diet. Corn distillers’ dried grains with soluble (DDGS), a bioethanol by-product, can replace up to 30 per cent of soybean and wheat in the fish diet without compromising the growth performance and nutrient utilization, said Zsuzsanna J. Sandor et al. in the study conducted in Hungary to evaluate the suitability of DDGS as a protein source for the fish. Corn DDGS is obtained after fermentation of corn by enzymes and yeast which produces bioethanol as major product. It is a suitable ingredient for fish due to its relatively high level of energy, protein, amino acid, non-phytate phosphorus and yeast protein and fat contents. The composition, however, varies between processing plants and among the grain used. Two experiments were conducted to evaluate the suitability of corn DDGS as a protein source for European catfish. ...
