Nebraska research shows dairy rations can contain up to 30 percent DDGS

A recent study by the University of Nebraska indicated that dairy cows could be fed by up to 30 percent distiller's dried grain in solubles (DDGS) when the feed ration is properly balanced.

In a publication entitled Utilization of Corn Co-Products in the Dairy Industry, which was produced by the University of Nebraska and the Nebraska Corn Board, information to dairy producers, nutritionists, extension educators, industry representatives was provided.

Kelly Brunkhorst, programme manager for the Nebraska Corn Board, said the electronic publication explains the basic corn dry milling process before covering the chemical composition and nutrient availability of distillers grains.

Details on feeding levels and production responses that are typical with feeding distillers grain were discussed further.

Feed co-products from the dry milling industry have been pointed as becoming common and cost effective ingredients in dairy diets. Assuming the price of distillers grains will continue to remain lower than corn grain and soymeal, researchers said it is easy to predict that rations including these feeds will be cheaper.

Brunkhorst explained that with the rapid growth of the ethanol industry, the production of distillers grains will also grow, providing a cost-effective feed ingredient option for dairy producers and their nutritionists.
