What is brewer’s grain? Barley
Malt
Mash
Spent Brewer’s Grains
Malting
Other Grains wheat, oats, rice, corn,
rye, sorghum

Malt, grains, hops and yeast must be organic for the brewer’s grain to be classified as organic.
Desirable Features
• Very palatable
• Good regional supply
• Highly digestible fiber
• Good bypass protein
• Can be ensiled
• Local and sustainable (organic may be limited)
Undesirable Features
• Wet, nutrient loss thru spillage and run-off
• Needs leak-proof hauling equipment
• Short storage life
• Low in starch (carbohydrates)
• May suppress intake of hay
• Price changes with local demand
• Pricey for some species – may not be a good buy for animals with lower nutrient requirements
• “Free” does not mean it should be used

Livestock
Pounds of Wet Brewers Grain/Day
Issues
Dairy cows Up to 40 Suppressed intake at high levels
Dairy goats Up to 2 May not consume that much
Preconditioning calves Up to 20 Best if mixed with dry grain
Weaned goat kids Up to 5 Best if mixed with dry grain
Replacement dairy heifers Up to 25 Supplemental energy needed
Pregnant sows Up to 10 Supplemental energy needed
Beef cows with calves Up to 20 May need added energy source
Dry cows Up to 10 Over feeding protein
Poultry Minimal Energy may be limited
Nursing sows Up to 5 Energy may be limited
Growing pigs Minimal Energy is limited
Mature horses Up to 20? Very limited information
Some General Guidelines
4
Procurement and Hauling
Procured within 1-3 days of production (seasonal) Procured from a clean, closed container Hauled with clean containers, truck or trailer Hauled with leak-proof containers, truck or trailer
Storage on the Farm
Containers such as large garbage cans with tops On a hard surface with run-off containment* In a small covered pile Limit storage to 7 to 14 days, depending on season Ensile for prolonged storage in silage bag
* Run off liquid has nutrients, so keeping it contained improves utilization.
Storage and Feeding on the Farm
Use very large trash can with bag inserted
Evacuate bag with shop vacuum
Close evacuated bag with double twist-ties
Store in coolest location possible in summer
Feed from top, evacuate and tie again
Feed daily for more consistent intake
Storage in Silo Bag
Bagger is attached to semi-trailer delivering WBG.
Bag is filled by dumping the trailer and moving forward.
Ensiled WBG lasts for months.
Best to purchase full load.
Bagging adds about $6 per ton to cost.

Feed Characteristics and concerns
Commercial pellets Easy storage, several byproducts, feed label
Distillers grains dried Easy storage, high nutrition, small quantities?
Average quality grass hay Good for maintenance in ruminants and horses
Food processing residuals Wet, highly digestible in ruminants, storage?
Spent produce Wet, highly digestible, may be organic, storage?
Soybean hulls Easy storage, good for ruminants, small quantities?
