There are many different goat breeds, each with unique characteristics and purposes. Some popular breeds include the Nubian, known for its long ears and milk production, and the Saanen, which is recognized for its high milk yield and calm temperament. Other breeds, like the Boer, are primarily raised for meat due to their muscular build. In addition to dairy and meat breeds, there are also fiber goats like the Angora and Cashmere goats, which produce valuable fibers. Miniature breeds, such as the Nigerian Dwarf, are popular as pets and for small-scale farming. Each breed serves specific needs in agriculture and companionship.
