Seven key points should be paid attention to in order to give full play to the benefits of feeding corn to pigs.

Corn is the most widely used feed. However, because its nutritional composition is relatively simple, there are many deficiencies. In order to give full play to the benefits of corn, we must pay attention to the following seven points when feeding pigs.

1. Don't simply feed. If you feed pigs with corn alone, for every 1 kg of weight gain, you need to consume more than 6 kg of corn. However, it takes only 2.5-3 kg of corn to feed pigs with formula feed.

2. Feeding after saccharification. After saccharification, corn flour can convert part of the starch into sugar, which can make pigs like to eat and grow quickly. The way to do this is to put the cornmeal into a human jar, then pour it into 2 times the fast-boiling hot water and fully stir it into a paste, then sprinkle 5 cm thick dry powder on its surface, and it will be saccharified after 3-4 hours.

3. Supply protein feed. Corn has low protein content and poor quality, which can not fully meet the growth needs of pigs. Therefore, protein feed must be supplemented. 15% bean cake or rapeseed cake can be added to the diet. 5% fish meal should be added to piglets.

4. Supply of minerals. The mineral content of corn is low, so bone meal, calcium hydrogen phosphate, selenium, iron, copper, zinc, manganese and so on should be added to the diet.

5. supply vitamins. The content of vitamins in corn is low, so green feed must be added when feeding. If there is a lack of green feed, multivitamins can be added to livestock and poultry.

6. It can not be stored for a long time after crushing. Corn should be crushed and fed, and the crushed corn flour should not be stored for a long time. Because of the high fat content of corn, it is easy to deteriorate after a long time. The amount of crushing should be used up in 15 days and 10 days in summer.

7. Soak before feeding. After soaking, corn can absorb water and expand and soften, and pigs are easy to chew, digest and absorb. Soaking method: soak the corn flour with 1-1.5 times of water for about 2 hours.
