Do not simply feed the practice to prove that the single use of corn to feed pigs, each 1 kg of weight, need to consume more than 6 kg of corn, but the use of feed to feed pigs only 2.5 to 3 kg of corn, can reduce the cost of feeding.
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 piglet.
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. Place the cornmeal in the jar, then pour 2 times the boiling hot water into a paste, and then sprinkle 5 cm thick dry corn flour on the surface. After 3 to 4 hours, the corn flour is saccharified.
Before soaking, it should be soaked in corn flour and add 1 to 1.5 times of water to soak for about 2 hours to make the corn expand and soften. Pigs are easy to chew and easy to digest and absorb.
