Cow dung, also known as cow pats, cow pies, cow poop or cow manure, is the waste product (faeces) of bovine animal species. These species include domestic cattle (cows). Cow dung is the undigested residue of plant matter which has passed through the animal's gut.

Cow manure is rich in nutrients and is suitable for plant growth. It has 3% nitrogen, 2% phosphorus, and 1% potassium—3-2-1 NPK, making it the right type of fertilizer for almost all types of plants and crops.
