Is it better to grind or fine corn to feed sows? Why?

The more unstable the factor, the more we must continue to strengthen our confidence and increase the intensity of science and technology breeding and management.

Pig raising is a scientific, meticulous and close industry, especially the breeding and management of sows, don't underestimate the size of corn grains. Because the various digestive organs of sows of different ages have different characteristics and requirements.

For example, gilts have just been weaned and changed their bellies, and the digestive system.

If the development is not perfect, the corn grains must be smaller, so that it is easier to digest, absorb and utilize, if the corn grains are too large, it will induce indigestion in piglets.

and diarrhea, which is not conducive to the absorption and utilization of nutrients. For example, young sows and adult sows have a well-developed and mature digestive system, and the corn grains should be coarser when feeding, so that it will be easier to digest and absorb and utilize nutrients.

Adult sows and young sows, if they continue to be fed fine and too fine corn pellets, form a fluid shape in the sow's stomach, which is prone to reflux into the stomach near the esophageal area. The lining of the stomach in the esophageal area against gastric acid.

The reaction of the increase is increase and thickening, enlargement. Hypertrophy is usually an effective defense mechanism, but if hypertrophy continues, these cells are not adequately nourished, and the connections between the cells are weakened to the point where gastric juice can come into contact with the structures of the submucosal tissues of the stomach.

This leads to damage to surface cells and erosions. In the long run, erosion can eventually lead to stomach ulcers.

of occurrences. This is the main reason for the sudden death of adult and pregnant sows in many large-scale farms in recent years.

Based on the above, friends should have a new understanding of sow feeding and corn grain size! In the daily corn feed grinding process, at least three sets of sieve blades are prepared for backup.

The sieve pore sizes are as follows:

Nursery sows: corn grains mm.

Young sows: Corn kernels mm.

Adult sows: Corn grains mm.

I think it's better to be finer, and the taste of the fine one is good, and the pig also likes it, and it's easy to digest after eating.

Good grinding can increase the satiety of rent, and it is also better for the digestion of pigs, if the corn is too rough, pigs will not eat it.

Coarse, because coarse cornmeal can promote his gastrointestinal digestion, and can also absorb nutrients better, so that it grows better.

Corn is the most basic food crop in our country.

One of them, in the northern region.

It is widely planted, especially in North China and Northeast China.

In 2019, China's corn harvest area was 41,284 thousand hectares, with a total output of 100 million tons, an increase over the previous year.

Corn is used as energy in feed**, accounting for the largest proportion of feed formulation, whether it is concentrate or premix, the proportion of corn is about 65%.

So is it better to beat the corn finely or coarsely when feeding the pigs? One of the misunderstandings about the use of corn is that the corn used for feed is not as fine as possible, but according to the growth stage of the pig.

Piglets rarely use premix or concentrate, because the farmer's own feed is raw feed, piglet digestive system.

The development is not perfect, and eating raw food can cause diarrhea.

Piglets use full price pellets at least before weaning, and the corn is puffed and pelleted, so that the piglets are well absorbed in the intestines.

Starting from nursery pigs, until the fattening pigs are slaughtered, the cornmeal is getting thicker and thicker, from weaning to 80 catties, the sieve pieces that can be used, from 80 catties to about 200 catties, the sieve pieces used, like this year, many people feed the pigs to 300 catties before they are slaughtered, and the sieve pieces that can be used.

The range of use of sieve discs is not fixed, and the size of the sieve discs to be used is determined according to the digestion of the feed by the pig herd.

Now piglets eat the opening material nursery material is puffed corn, corn after high temperature puffing, and puffed soybean meal.

and other trace elements.

One piece of granulation. The opening material made has a fragrance, which improves the feed intake of piglets, can also improve intestinal digestion, and reduce diarrhea, which can not be done with small sieve pieces to beat corn.

After weaning piglets, the corn sieve must be small, if the sieve is too large, the corn is too large, the piglet can not digest and absorb, and it is easy to have diarrhea.

However, if the fattening pig is more than 100 pounds, it is not good to use a small sieve, the corn is too fine, and the pig is easy to paste when eating, which is not conducive to the digestion and absorption of feed.

The needs of each stage of pig growth and development are different, and different sizes of sieve pieces are used to beat corn according to different stages to meet the growth needs of pigs.

It should be noted that before using corn, it is necessary to do a good job of inspection, and pick out the moldy and spoiled corn to prevent the mycotoxins in the prepared feed from exceeding the standard and affecting the growth of the pig herd.

It is better to use corn flour for pigs, which is conducive to the absorption and growth of pigs.
