Animal husbandry is the branch of agriculture concerned with raising livestock. It includes the breeding, rearing, and management of animals such as cattle, sheep, pigs, horses, poultry, and fish. Animal husbandry practices vary widely across the world. Some countries rely heavily on pastoralism, while others predominately use industrial farming techniques. However, all animal husbandry methods share a common goal: to produce safe and healthy livestock that can be used for meat, milk, eggs, or fiber.
