How did the animal husbandry in New Zealand develop?

Animal husbandry in New Zealand began in 18 14. At that time, British immigrants brought two cows and a bull into New Zealand to meet the basic needs of life. With the continuous reproduction of livestock and the gradual expansion of pasture, the development of animal husbandry such as cattle raising and dairy industry has been promoted. The unique geographical environment and the continuous innovation and transformation of technology have made the animal husbandry in New Zealand develop rapidly.
