Cow dung, also known as
cow pats,
cow pies 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. Colour ranges from greenish to blackish, often darkening soon after exposure to
air.
