First, do not simply feed. Pure corn is used to feed pigs and consumes 6 kilograms of corn for every kilogram of weight gain. Feeding pigs with compound feed requires only 2.5 kg - 3 kg.

Second, feeding after saccharification. After mashing corn flour, some starch can be converted into sugar, which can make pigs eat fast. The method is: put the corn flour into the tank, then pour 2 times of hot water to the mixture and stir it into a paste. Sprinkle 5 cm thick dry powder on the surface and saccharify it after 3-4 hours.

Third, the supply of crude protein content is low and the quality is poor, which can not fully meet the growth needs of pigs. 15% bean cake or rapeseed cake can be added to the diet. For example, piglets should be added 5% fish meal.

Fourth, the supply of minerals. The content of mineral elements in corn is low, so bone minerals, calcium hydrogen phosphate and trace elements such as selenium, iron, copper, zinc and manganese should be added to the diet.

Fifth, supply vitamins. Corn has low vitamin content. When feeding, it must be fed with green and green feed, which can add multivitamins to livestock and poultry.

6. It cannot be stored for a long time after crushing. The corn should be smashed and fed, and the crushed corn noodles are prone to deterioration over time. The amount of pulverization should be used up to 15 days, and it should be used up in 10 days in summer.

7. Soak before feeding. Corn is soaked to absorb water and expand and soften. Pigs are easy to chew and easy to digest and absorb. The soaking method is to soak the corn flour for 1 to 1.5 times of water for 2 hours.
