Livestock breeding, such as pigs, cattle and sheep, is a major pillar in the aquaculture industry. With the improvement of the quality of life, people pay more attention to the choice of food, and livestock products are popular because of their rich nutrition. Pork has become a frequent visitor on people's table because of its delicate taste and rich nutrition. Beef and mutton, because of their high protein and low fat, are favored by healthy dieters. For those who are interested in livestock breeding, they should not only have enough funds to prepare, but also need to constantly learn and accumulate experience to ensure the stable development of livestock breeding.
