Quality DDGS depends on grain type

When it comes to using distiller's grains in finishing rations of High Plains cattle, a Texas AgriLife Research scientist says the type of grain used makes all the difference.

Two years ago, Dr. Jim MacDonald, AgriLife Research beef nutritionist at Amarillo began investigating the dramatically different animal performance responses observed in the Northern Plains and Southern Plains, and to determine how to successfully incorporate distiller's grains into this region's finishing rations. "There are two obvious differences in research conducted in those two regions," he said. "Researchers in the Northern Plains tend to use dry-rolled corn, and in the Southern Plains, they use steam-flaked corn-based diets."

Additionally, researchers in Nebraska and other Northern Plains states utilized distiller's grains derived from corn; whereas the southern research included distiller's grains derived from sorghum, he said. MacDonald conducted three performance trials, two using corn-based distiller's grain shipped in from a Nebraska plant, and the third utilizing sorghum-derived distiller's grains that were similar to those used in research previously conducted in this region.

Different energy value
"Our study in feeding sorghum distiller's grain at 25 percent of dry matter, showed the energy value for that product was 73 percent of the value of steam-flaked corn," MacDonald said. "In general, that fits with previously conducted research at Texas Tech and West Texas A&M."

Alternatively, he said, the research conducted with corn-derived distiller's grains from Nebraska would suggest the energy value was roughly equivalent to steam-flaked corn, which agrees with the northern data where distiller's grains were fed in steam-flaked diets.

"So what our observations are showing us is there are large variations in the energy value of distiller's grains derived from different cereal grain sources, similar to the differences in energy values of the cereal grains themselves," MacDonald said.

There will be a place for all of the different types of distiller's grains produced, but the producer needs to know what the energy value is and the product needs to be priced appropriately, he said. MacDonald said another important thing for producers to understand is that distiller's grains from each plant may be different, so it is important to have a relationship with the provider of distiller's grains.
