Corn is the most widely used feed, but its nutrients are relatively simple. In order to maximize the feeding effect of corn, the following points must be paid when feeding pigs.
Feed after saccharification . After mashing corn flour, some starch can be converted into sugar, which can make pigs eat fast. The main method is to put the corn flour into the tank, then pour 2 times of hot water to make a paste, and sprinkle 5 cm thick dry powder on the surface, and saccharify after 3 to 4 hours.
Add trace elements . 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.
Add 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.
Soak before feeding . After soaking, the corn can absorb water and expand and become soft. The pig is easy to chew and easy to digest and absorb. Therefore, it should be soaked in corn flour for 1 to 1.5 times of water for 2 hours.
Add protein feed . Corn has low protein content and poor quality, which cannot meet the growth needs of pigs. Therefore, protein feed must be properly supplemented, 15% bean cake can be added to the diet, and 5% fish meal can be added to the piglet.
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. Because corn has a high fat content, it is 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.
Do not feed alone . Pure corn is used to feed pigs and consumes 6 kilograms of corn per kilogram of weight gain, while feeding pigs with compound feed requires only 2.5 to 3 kilograms.
