Large scale production of dairy in Ohio has had notable impacts on water and air quality in surrounding area, largely from cow manure. [4] The dairy industry in Ohio produces around 23 million kilograms of manure daily as of 2016. Inside that manure is around 136,000 kg of nitrogen and 15,000 kg of phosphorus which often runs off and pollutes ...
Cow dung, also known as cow pats, cow pies, cow poop or cow manure, is the waste product of bovine animal species. These species include domestic cattle ("cows"), bison ("buffalo"), yak, and water buffalo. Cow dung is the undigested residue of plant matter which has passed through the animal's gut. The resultant faecal matter is rich in minerals
As the manure decomposes, it emits biogas. The biogas is captured and processed to remove moisture and carbon dioxide.
Production below 12 to 15 L (2.6 to 3.3 imp gal; 3.2 to 4.0 US gal) of milk per day is not economically viable. [30] [failed verification] [citation needed] Cow longevity is strongly correlated with production levels. [31] Lower production cows live longer than high production cows, but may be less profitable.

The concept of an animal unit (AU) has traditionally been used in North America to facilitate planning, analysis and administration of forage use by grazing livestock, but the term has also had other applications (in relation to odor control regulation, feedlot size, manure management, etc.). The term has been variously defined by regulation in ...
A cattle feedlot too small to need a state-required manure management plan has apparently polluted Iowa streams for years, the Iowa DNR says
Since 1960 average cow's milk production has increased from 5-kilogram /day (11 lb) to 30-kilogram /day (66 lb) by 2008, as noted by Dale Bauman and Jude Capper in the Efficiency of Dairy Production and its Carbon Footprint. The article points to the fact that the carbon footprint resulting from the production of a gallon of milk in 2007 is 37% ...
