Seven Tips for Feeding Pigs with Corn
Corn is the most widely used fodder, which also has many shortcomings because of its relatively simple nutrients. To maximize its benefits, we must pay attention to following points when feeding pigs.
1. Do not feed pigs with only corn. If use corn only, increasing 1 kg of pig needs to consume more than six kilograms of corn, while it only needs 2.5 to 3 kilograms of corn if feed pigs with compound feed.
2. Saccharify before feeding. Part of starch can switch into sugar after corn has been saccharified, which can stimulate pigs’ appetite. Specific operating methods are: first, pour corn flour into cylinder; then add 2 times hot-water and stir into a paste; at last, sprinkle 5 cm of dry powder over its surface. After 3 to 4 hours, the corn will be saccharified.
3. Feed with protein feed. Due to the low content and poor quality of corn protein, corn cannot fully meet the growing needs of pigs. Therefore, protein fodder is necessary. Farmers can add 15% soybean or rapeseed cake in the diet, and 5% fishmeal for piglets.
4. Feed with minerals. As corn has low mineral content, hence, bone meal, calcium hydrogen phosphate, selenium, iron, copper, zinc, manganese, etc. should be added in the diet.
5. Feed with vitamins. Vitamin contained in corn is low; then, green feed must be added. If not, multivitamin is also OK.
6. Corn cannot be saved for long-term after being crushed. Because of the high fat content, the crushed corn is easy to deteriorate. It is better to crush quantitative corn that can be used up in 15 days and 10 days in summer.
7. Corn should be soaked before feeding. The soaked corn is soft and easy to chew and digest for pigs. Soaking method: add 1 to 1.5 times water to corn and soak about 2 hours.
