s. In cold places, cow dung is used to line the walls of rustic houses as a cheap
thermal insulator. Most of the villagers in India spray fresh cow dung mixed with water in front of the houses to repel insects. It is also dried into cake like shapes called Upla or Kanda and used as replacement for firewood for cooking in chulah.
In Rwanda, it is used in an art form called
imigongo.
Cow dung is also an optional ingredient in the manufacture of adobe
mud brick housing depending on the availability of materials at hand.
A deposit of cow dung is referred to in American English as a "cow pie" or less commonly "cow chip" (usually when dried) and in British English as a "cowpat". When dry, it is used in the practice of "cow chip throwing" popularized in
Beaver, Oklahoma in 1970. On April 21, 2001 Robert Deevers of Elgin, Oklahoma, set the record for cow chip throwing with a distance of .

Chhattisgarh India started buying cow dung under "

Ecology
Cow dung provides food for a wide range of animal and fungus species, which break it down and recycle it into the
food chain and into the
soil

In areas where cattle (or other mammals with similar dung) are not native, there are often also no native species which can break down their dung, and this can lead to infestations of pests such as flies and parasitic worms. In
Australia,
dung beetles from elsewhere have been introduced to help recycle the cattle dung back into the soil. (see the

Cattle have a natural aversion to feeding around their own dung. This can lead to the formation of taller ungrazed patches of heavily fertilized sward. These habitat patches, termed "islets", can be beneficial for many grassland arthropods, including spiders (Araneae) and bugs (Hemiptera). They have an important function in maintaining biodiversity in heavily utilized pastures.

Bison dung is sometimes referred to by the name ''nik-nik''. This word is a borrowing from the
Sioux language (which probably originally borrowed it from a northern source). In modern Sioux, ''nik-nik'' can refer to the feces of any bovine, including domestic cattle. It has also come to be used, especially in
Lakota, to refer to lies or broken promises, analogously to the vulgar English term "
bullshit" as a figure of speech.
