Brewers and distillers grains have been used as animal feeds for centuries. Wet brewers (WBG) and wet distillers (WDG) grains may also be available and used as feeds on farms. Using WBG and WDG as animal feed recycles feed nutrients and reduces the environmental impact of disposal in landfills, incineration, and composting. Using these feeds on the farm can also help in controlling purchased feed costs and improving profitability. Wet brewers and wet distillers’ grains can provide beneficial nutrients to the dairy cow diet. Storage considerations, key benefits, and constraints of using WBG and WDG are covered.
