Protein supplemented feed corn has low protein content and poor quality and cannot fully meet the growth needs of pigs. Therefore, protein feed must be added. You can add 15% bean cake or rapeseed cake to the pig diet, and add 5% fish meal to the pig.
The vitamin content of vitamin corn supplement is low. When feeding, green feed must be added and vitamins must be added. In the absence of green feed, a variety of vitamins can be added to livestock and poultry.
Minerals supplemented with minerals have low mineral content and a single nutrient content. Therefore, bone powder and calcium hydrogen phosphate, selenium, iron, copper, zinc, manganese and other minerals should be added to the pig diet.
After saccharification and feeding of corn meal, some starches can be converted into sugars after saccharification. The pigs prefer eating fast. Practice: put corn flour into the tank, then pour 2 times boiling water into a paste, and then spread 5 cm thick dry corn flour on the surface, after 3 to 4 hours of corn flour is saccharification.
Before soaking, it should be soaked in corn flour with 1~1.5 times of water soaking for about 2 hours to make the corn expand and soften. Pigs are easy to chew and easy to digest and absorb.
