*Cow dung is the undigested residue of herbivorous 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 in colour soon after exposure to air.

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.

In recent times, the dung is collected and used to produce biogas to generate electricity and heat. The gas is a rich source of methane and is used in rural areas of India and elsewhere 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 a cheap thermal insulator.

It was also used extensively on Indian Railways to seal smoke boxes 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.
