Sub powder can replace corn as feed?

Animals need protein, amino acids, calcium, phosphorus, energy... rather than soybean meal, corn, etc. All raw materials containing energy can replace corn, and not only corn can feed pigs; similarly all raw materials containing protein and amino acids can be used instead of soybean meal. As China has more people and less land and food resources are in short supply, the development of unconventional feed ingredients is inevitable for the development of animal husbandry. This point we should learn from European countries. The US corn pod diet is not suitable for China's national conditions, because the United States is a world grain country. European countries have a small area and low food production. Learning from the European national recipes can be found out that their formula has only a few corn and pods or none at all, but the feeding effect is indeed first class, which is exactly what we want to learn. The application of corn is becoming more and more widespread. Starch, sugar, ethanol, lysine and other industries use corn as raw material, which causes high corn prices. The secondary powder is cheap and easy to obtain, nutrient-rich, and the protein level is 6% higher than that of corn. The level of digestion energy after adding xylanase is equivalent to corn, and the cost performance is significantly higher than that of corn. It is an excellent raw material to substitute corn for reducing the cost of feeding. However, the nutritional content of the secondary powder is quite different from that of corn. For example, there is almost no riboflavin in the secondary powder, the bioavailability of biotin is almost zero, and the folic acid content and linoleic acid content are significantly lower than those of corn. In order to use sub-powders for good production performance, sub-powder concentrates must be used. Recommended formula for pig feed: sub-powder or wheat 86%, soybean meal 10%, premix (SC452) 4%
