How to improve sow lactation

Sows play a very important role in raising pigs, and the reproductive ability of sows determines the whole herd of pigs. Sows need to feed piglets, so their management is very important. When we raise and manage sows, we often have all kinds of problems. Especially the problem of postpartum lactation of sows, so how can we improve the lactation of sows when raising sows? Let's take a look at it with the editor.

1. Promote the development of breast.

The breast of a sow develops two and a half years before the sow grows. Lactation is the main time of mammary gland development, and mammary gland development and activity are carried out alone. Piglets habitually suck a nipple after birth until they are weaned. Therefore, if the number of babies is small, for example, when there are only about 8 nipples, only 8 nipples are used. So only the nipple used can develop, and the other nipples will stop developing. The reduction of solvent results in the reduction of other remaining nipples. Therefore, when the sows give birth to fewer babies, we should let the young pigs have the habit of sucking two nipples to promote the development of all nipples and mammary glands and ensure the lactation of the sows throughout their lives.

2. Feed preparation

When we feed sows, we should pay attention to rational preparation according to the nutritional needs of sows. Ensure the balance of energy, protein, minerals, vitamins and other nutrients. Inadequate nutrition will not only reduce the lactation of sows, but also easily lead to paralysis of sows. Therefore, increasing the proportion of feed nutrition in the first month of pregnancy and lactation of sows can effectively promote the development of mammary glands of sows and increase the amount of milk production. The nutrition of breast milk is very rich, as long as adequate feed and drinking water are guaranteed, the quality and secretion of breast milk can be guaranteed.

3. Regular feeding

Sows should be fed about three times a day, and it is appropriate to feed sows at 8am, 1pm and 8pm every day. And when feeding in the morning and evening, we should pay attention to increase the feeding amount properly, which can increase the food intake of sows and promote lactation. During lactation, sows have the greatest demand for nutrition during the whole breeding period, so they cannot be fed according to the method of pregnancy. In order to ensure that sows have adequate nutrition in lactation, it is necessary to feed them frequently and less at the same time. During the lactation period of sows, feed stability should be ensured, feed varieties should not be changed easily, feed quality should be guaranteed and milk production of sows should be improved.

4. Manual massage

The lack of lactation in sows is partly due to the imperfect development of the lactation system. Therefore, we can promote the breast development of sows by artificial massage of sows. It is usually carried out half a month before production and about a week after production. Twice a day before giving birth, gently knead the sow's breasts with your hands for about 20 minutes. After giving birth, massage with a warm towel of about 50 degrees on the breast, also twice, for ten minutes each time. In this way, it can effectively increase the milk yield of sows. At the time of massage, we can also observe whether the sow nipple is blocked, and the blockage can be extruded in time.

The above is a brief introduction to how to improve the milk yield of sows. To improve the lactation of sows, the breeding environment is also very important, and traditional Chinese medicine can also be used to promote the lactation of sows, which can effectively promote the lactation of sows. That's all for today's introduction. This article is for reference only. I hope it can help you all.
