DSD 6.5 | Performance of High protein Corn coproduct

For decades, ethanol production has generated affordable biproducts to feed. A new distilling method has generated a product with ~50% protein. Dr. Billy Brown, assistant professor of dairy science at Kansas State, wanted to understand how this feed would compare to soybean meal in a starter grain.

To test this he developed rations substituting soybean meal 1:1. Graduate student Rachel Skinner measured intake, growth, effiency and metabolic and digestive parameters to best understand if this product would work in post weaning phase of production.
