Water buffalo come from Asia and are one of the world’s oldest livestock breeds.
They originated in India and are used by farmers across the east because they are an extremely durable and hardy breed.
In Asia they are often used to work in place of tractors and as a source of milk and butter for cooking.
They are also ideal for grazing in wet, swampy areas, and have been used in places like the Teifi Marshes in West Wales for many years.
It is believed they help to maintain these habitats thus encouraging migratory birds, insect populations and also amphibians to thrive.
