How to breed sows

After the sow is pregnant, the fertilized egg begins to grow and develop. Sows not only meet their own nutritional needs, but also provide nutrients needed for embryo growth and development. Therefore, sows must be fed more protein and vitamin-rich feed in the early stage of pregnancy, and the feed quality must be better with good green feed. About 20 days after pregnancy, fertilized eggs begin to transplant to the uterine horn to form placenta, but it is easy to miscarry during this period. Therefore, it is necessary to strengthen the management of sows at ordinary times to prevent sows from falling, fighting and squeezing, and to prevent sudden changes in feed and environment from getting sick. It is forbidden to feed moldy, rotten, deteriorated and frozen feed, and the feed should be comprehensive in nutrition, so as not to cause the fertilized egg to stop developing and die. After two months of pregnancy, you should be kept in captivity alone, strengthen exercise, bask in the sun every day, and it is strictly forbidden to whip and jump into the ditch to protect the fetus; After three months of pregnancy, sows enter the second trimester. At this time, the green feed can be reduced appropriately, and the concentrated feed is increased compared with the previous period, and the daily feed is about 2.5 kg. Pay special attention to feed and calcium supplementation in protein. When sows are near delivery, they should reduce the concentrate properly to avoid mastitis and dry stool, so as to ensure the smooth delivery of piglets.
