A cow can produce as much as 120 pounds of wet manure in a single day, depending on the size and breed of the animal. Cow manure is a combination of bedding material, solid waste and wet waste.
An adult cow can drink up to 30 gallons of water a day and eat up to 24 pounds of hay. It can produce up to 4 gallons of urine or wet waste per day. The same cow can produce up to 65 pounds of excrement or solid waste per day. An adult cow has to relieve its bowels up to 15 times per day. Bedding materials such as straw or sawdust blend with the waste a cow produces to form manure.
