There's more to feeding corn to pigs than meets the eye, and using the right method matters

Do not feed corn alone. Practice has shown that when corn is fed to pigs on its own, more than 6 kg of corn is needed for every 1 kg of weight gain, whereas with a compound feed only 2.5-3 kg of corn is needed, which lowers feeding costs.

Supplement with protein feed? Corn is low in protein and the quality is poor, so it cannot fully meet the growth needs of pigs. Therefore, protein feed must be supplemented. You can add 15% soybean cake or rapeseed cake, etc., to the pig's daily ration; when feeding piglets, 5% fish meal should be added.

Supplement with vitamins? Corn is low in vitamins, so green fodder must be added when feeding to supplement vitamins. If green fodder is unavailable, a multivitamin for livestock and poultry can be added.

Supplement with minerals? Corn is low in minerals and its nutrient composition is one-sided, so bone meal and minerals such as calcium hydrogen phosphate, selenium, iron, copper, zinc and manganese should be added to the pig's daily ration.

Feed after saccharification? After corn meal is saccharified, part of the starch can be converted into sugar, which pigs like to eat and which makes them grow quickly. Put the corn meal into a crock, pour in 2 times its volume of nearly boiling hot water and stir thoroughly into a paste, then sprinkle a 5 cm thick layer of dry corn meal on the surface; after 3-4 hours the corn meal will be saccharified.

Should it be soaked before feeding? Add 1-1.5 times its volume of water to the corn meal and soak for about 2 hours, so that the corn swells and softens, making it easy for pigs to chew and easy to digest and absorb.
