What is the effect of carbohydrates on pigs
Carbohydrates, which are composed of carbon, hydrogen and oxygen, are the main components of plants, accounting for about 70%, 80% of all plant nutrients, and are the main source of energy in pig feed. Carbohydrates are converted into energy after a series of changes in pigs, providing heat for various life activities of pigs. After meeting the daily energy consumption, the remaining carbohydrates can be converted into fat and stored in pigs as energy reserves for use when hungry. Pig fat and suet are the reserves of this remaining energy.
