Corn feeding pig's attention

One must feed 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 tank, then pour 2 times the hot water of quick-opening to fully stir into a paste, sprinkle 5 cm thick dry powder on the surface, and saccharification after 3 to 4 hours.

Second, add the cake feed. Supply crude protein content is low and poor quality, can not fully meet the growth needs of pigs, can be added in the diet 15% bean cake or rapeseed cake and so on. Such as piglets should be added 5% fish meal.

Third, add trace elements. 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.

Four to add vitamins. Low levels of vitamins in corn, feeding must be fed green feed, can be added to livestock and poultry vitamins.

Five to 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 in corn flour and soak for 2 hours.

Do not simply feed. Feeding pigs with pure corn consumes 6 kg of corn for every 1 kg of weight gain. The use of compound feed to feed pigs only 2.5 to 3 kg.

Do not crush after long-term storage. 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.
