Corn is the most widely used feed. However, due to its relatively simple nutritional composition, there are many shortcomings. In order to give full play to the benefits of corn, pig e net users recommend the following points when feeding pigs. 1. Do not feed alone. Feeding pigs with corn alone requires 1 kg of corn per kilogram of weight gain. Feeding pigs with compound feed requires only 2.5 to 3 kg of corn. 2. Feed 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 in the tank, then pour 2 times of hot water to make a paste, then sprinkle 5 cm thick dry powder on the surface, and saccharify after 3 to 4 hours. 3. Supply protein feed. Corn has low protein content and poor quality, which cannot fully meet the growth needs of pigs. Therefore, protein feed must be added. 15% bean cake or rapeseed cake can be added to the diet. Piglets should be added 5% fish meal. 4. Supply minerals. Corn has low mineral content, so bone powder, calcium hydrogen phosphate, selenium, iron, copper, zinc and manganese should be added to the diet. 5. Supply vitamins. Corn has low vitamin content and must be fed with green feed when feeding. If you lack green feed, you can add multivitamins to livestock and poultry. 6. Do not store for a long time after crushing. Corn should be smashed and fed, and the crushed corn noodles should not be stored for a long time. Due to the high fat content of corn, it is prone to deterioration after a long 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. Soaking method: soak 1 to 1.5 times of water in corn flour for about 2 hours.
