Enhancing the feeding value of corn distiller’s grains for pig and poultry diets in the US

US researchers suggest a way to improve the overall feeding value of corn distiller’s dried grains with solubles for monogastric animals. Corn distiller’s dried grains with solubles (cDDGS) from the corn-ethanol dry-grinding process has become a major feed ingredient used extensively in US ruminant diets but less so in monogastric animal diets. The ingredient tends to have imbalanced key amino acids (AA), high indigestible fiber and phytate, and risk of mycotoxin contamination, aspects that thus limit its inclusion rate in the diets of poultry and pigs. A team from the Department of Animal Science, University of Minnesota, St Paul, which included leading experts, Dr Gerald Shurson and Dr Pedro Urriola, set about finding a way to improve the feeding value of cDDGS. Earlier investigations Several avenues have already been explored in this respect, they noted in a paper published in Animal Feed Science and Technology​​. “Examples include direct addition of exogeneous enzymes ...
