Animal feed is the food given to livestock, especially livestock, in the process of animal husbandry. Animal feed is a heavy investment in animal agriculture and is often the main cost of raising animals. In farms, finished feed is generally used as animal feed. In the process of animal husbandry, not only do you need to mix a variety of finished feeds in a certain ratio when feeding different animals, but you also need to adjust the best ratio of a variety of finished feeds according to the growth and development of the animals and different growth cycles, and then mix and feed them, so as to achieve the best animal health growth state and achieve the best input-output ratio.
