Animal breeds refer to specific groups of domesticated animals that share distinct characteristics, such as appearance, behavior, and genetic traits. These breeds are often developed through selective breeding practices to enhance desirable qualities, such as size, color, or temperament. Common examples include dogs, cats, horses, and cattle. Each breed serves different purposes, from companionship to work and production. For instance, herding dogs are bred for their ability to manage livestock, while show horses are selected for their beauty and grace. Understanding animal breeds helps in choosing the right pet or livestock for various needs.
