Practice has shown that soybeans have been cooked and destroyed anti-trypsin in soybeans, increased palatability, improved digestibility and nutritional value; at the same time increased the effective methionine and cystine in soybean protein, increased the biological value of the protein . However, cooking time should not be too long, usually about 50 minutes. 5. Roasting sweet and sweet roasting is mainly a way to feed the piglet with a processing concentrate. The grain feed, especially the cereal grain feed, after passing through a high-temperature furnace at 130-150°C for a short time, part of the starch is converted into dextrin, which improves the utilization rate of the starch and eliminates harmful bacteria. The feed is sweet, delicious and crispy. Increase appetite, good feeding effect. 6. Silage Preservation The green material is stored in various pits, ponds, and tanks and fermented under anaerobic conditions to produce lactic acid.
