Cow dung is a term used for the feces of the bovine species. The species includes the cow, buffalo, ox and bullock. Cow dung is basically the digested residue of herbivorous matter which is acted upon by symbiotic bacteria residing within the animal's rumen. The resultant faecal matter is rich in minerals. Colour ranges from greenish to blackish. In due course, the resulting matter turns yellow due to chemical changes caused by sunlight.
Uses
In many parts of the developing world, cow dung is used as a fertilizer and fuel. Caked and dried cow dung is used as a fuel to cook food in many parts of Asia and Africa. Especially in India where it is known as gobar, cow dung is also used as manure.
In recent times, the dung is collected and used as biogas used to generate electricity and heat. The gas is a rich source of methane and is used in rural areas of India to provide a renewable and stable source of electricity.
Cow dung is also used to line the floor and walls of buildings owing to its insect repellent properties. In cold places, cow dung is used to line the walls of rustic houses as is a cheap thermal insulator. Cow dung has an excellent mosquito repellent property and is used by many companies to produce repellents.
It was also used extensively on Indian Railways to seal smokeboxes on steam locomotives.
Cow dung is also an optional ingredient in the manufacture of adobe mud brick housing depending on the availability of materials at hand.[1]
