Animal waste refers to the excrement produced by animals, including feces and urine. It is a natural byproduct of digestion and can vary in composition depending on the animal's diet. Common sources of animal waste include livestock such as cows, pigs, and chickens, as well as pets like dogs and cats. Animal waste plays a significant role in agriculture, as it can be used as fertilizer to enrich soil and promote plant growth. However, improper management of animal waste can lead to environmental issues, such as water pollution and the spread of diseases. Therefore, effective waste management practices are essential for both agricultural productivity and environmental health.
