Can dairy producers feed reduced-fat distillers grains to dairy heifers and still get the type of replacement heifer they want?
This research found that by increasing the level of distillers grains and using a limit-fed feeding strategy, researchers were able to increase the feed efficiency for heifers. Researchers also found improved digestibility of the proteins and dry matter of the rations as inclusion of distillers grains increased. The heifers body condition did not change by feeding this diet, so animals did not end up over-conditioned.
This research demonstrates that ethanol plants can grow this particular market for their feed products, while livestock producers get a simple, low-cost, effective feed ration.

Within the vast world of value-added agriculture, it is important for an organization like AURI to keep efforts focused and true-to-mission year-after-year. One of the central methods AURI uses to accomplish this is by identifying key research themes and priorities to guide its efforts. These research themes represent the focus of the organization’s work and […]
By AURI One of the most important issues faced by farmers and ag producers is that of nitrogen runoff from their fields into the surface water supply via tile drainage systems. This runoff of nitrogen has a negative effect on water quality, and contributes to a hypoxic zone in the Gulf of Mexico. However, a […]
