Do not simply feed: pure corn to feed pigs need to consume 6 kilograms of corn per kg of weight gain. The use of compound feed to feed pigs only 2.5 to 3 kg of corn.
Feeding after saccharification: After corn flour is saccharified, it can convert part of the starch into sugar, which can make pigs like food faster and longer. The practice is: put the corn flour into the tank, then pour 2 times the hot water of quick-opening to fully stir into a paste, sprinkle 5 cm thick dry powder on the surface, and saccharification after 3 to 4 hours.
Supply of crude protein feed: The crude protein content in corn is low and of poor quality, and it cannot fully meet the growth needs of pigs. You can add 15% bean cake or rapeseed cake to your diet. Such as piglets should be added 5% fish meal.
Supply of minerals: The content of mineral elements in corn is low, so bone powder, calcium hydrogen phosphate and selenium, iron, copper, zinc, manganese and other trace elements should be added to the diet.
Supply of vitamins: Corn has low vitamin content and must be fed with green feed. In the absence of green feed, a variety of vitamins can be added to livestock and poultry.
After smashing, it cannot be stored for a long time: corn should be crushed and fed, and the comminuted corn will be deteriorated for a long time. It is advisable to use the crushed amount in 15 days, and it is better to use 10 days in the summer.
Before soaking, the corn should be soaked: Corn can absorb water to swell and become soft after being soaked. The pig is easy to chew and easy to digest and absorb. Soaking method: add 1~1.5 times of water in corn flour and soak for 2 hours.
