Corn is known as the “king of feeds” and it usually accounts for more than 60% of the pig's compound feed. Therefore, the choice of corn is very important.

First, choose fresh and high-quality corn, especially piglets and breeding pig feed, must use good. Now some corn traffickers will make a fuss and go to the countryside to collect some corn from the farmers to discard the moldy corn. Then they will be sold in good corn. Some of them are not mixed, and only some of them are mixed, but they don’t look closely. It is ugly to see that even if such corn is cheaper, it will cost more than the price of good corn. Do not buy such corn.

Second, it is best to buy large grain corn. This kind of corn generally contains more starch and has sweet taste. It is the best feed for pigs. It is best not to choose some of the small-grained, alfalfa. There are some things that are not available. After crushing, corn starch is also less. Poor sex.

Try to buy naturally dried corn. Naturally dried corn is easy to distinguish between good and bad, and many of the dried corn is immature corn and spoiled corn. After drying, it looks good on appearance and has a great chance of quality problems. This kind of corn generally has skin wrinkles. More pleats, poor fullness, not bright.

Third, corn contains more fatty acids, grated corn flour is easily rancid, try not to store too long, especially in the summer, to find people smashing the farmers must remember.

The grain size of corn should be appropriate. After the weaning, because the digestive rate is not good, it should be crushed with a small sieve to promote better absorption. For fattened pigs and sows, you can increase the size of the sieve holes. If your weight is too small, the pig's appetite will be reduced. It will also take time and effort to crush the feed.

Fourth, it is best not to use corn with high moisture content. First, mildew is prone to occur during storage. Second, the concentration of feed is decreased. If you forget to increase the proportion of corn, the dietary nutrition will be uneven. The corn moisture of the farm is best controlled at 14 to 15%. Choose a corn and grasp it with a stinging hand. Use your fingers to struggle and the teeth bite.
