First, do not simply feed. Purely corn-feeding pigs consume six kilograms of corn per kilogram of weight gain. The use of compound feed to feed pigs only 2.5 kg - 3 kg.
Second, 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 cylinder, then pour 2 times the quick-opening hot water and stir it into a paste. Sprinkle a 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 poor quality, can not fully meet the pig's growth needs. You can add 15% bean cake or rapeseed cake to your diet. Such as piglets should be added 5% fish meal.
Fourth, 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.
Fifth, supply vitamins. Low levels of vitamins in corn, feeding must be fed green feed, can be added to livestock and poultry vitamins.
Six, after long-term storage can not be crushed. The corn should be crushed and fed, and the comminuted cornmeal will be perishable 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.
7. Soak before feeding. Corn soaked absorbs water and expands and softens. Pigs are easy to chew and easy to digest and absorb. Soaking method is to add 1-1.5 times of water soaking in corn flour for 2 hours.
