The amount of manure produced daily by a dairy cow differs depending on whether or not the cow is giving milk, the bedding used in the barn and breed and adult weight. The average cow produces 120.5 lbs. of mixed feces and urine and 16.8 lbs. of qualified solid waste over the course of a day, according to the United States Environmental Protection Agency.
Dairy cow manure is gathered from barns and heaped or piled for use in agricultural fertilization. Sometimes manure is stored in a pit where it must be agitated back into a semi-liquid state before it can be loaded onto a spreader and taken to fertilize a field.
Sometimes manure is put through a process called solid separation. This most frequently involves straining liquid manure through a cloth filter or screen until it has been largely separated from the solid components of manure which can then be used or else dried to last through long periods of storage.
Manure piles can be used as power plants if there is a method present to capture the methane it releases. The methane can be used to turn a turbine and thus produce electricity for use by a farm or grid with the right equipment and infrastructure in place.
