How much do dairy cows eat in a day?
Dairy cows that are lactating (producing milk) eat approximately 50 pounds of dry matter per day. Converting this to as fed weight of the feed depends on the moisture content of the feedstuffs used. Assuming 50% moisture it would be approximately 100 pounds of feed that a cow would eat per day. She would also consume roughly 50 gallons of water every day while she is lactating.
