Recent changes in corn and sorghum processing for ethanol have led to changes in the composition of grain byproducts, including distiller’s dried grains with solubles, a major component of swine feed, reports AgriNews.
As a result, today’s DDGS is typically higher in the amino acid leucine than is necessary to meet nutritional requirements of pigs.
According to research from the University of Illinois, excess leucine in pig diets can decrease protein synthesis and reduce feed intake.
