For pregnant sows to be scientifically fed, to meet the nutritional needs of the fetus at various stages of pregnancy. Give sows reasonable sensation, plus reasonable exercise. Smoothing the sow and secreting a high enough amount of milk makes the piglets grow up healthily. Specific practices include: limited breeding after 20 days of breeding. About 3-4 pounds per day with materials. Medium-term 4--5 kilos of material. Appropriate exercise, use high quality materials, reject mildew material. In the following month, the daily increase of the feeding amount of 3--4 was conditionally increased by the green feeding, and the feeding amount was reduced to the normal amount in the last week. The feed was stopped on the day of production.
2, production must be manually monitored
Artificial guardianship can help the weak, the dead, and the midwifery. Especially the reserve first child, there are not recognized pigs, arch bite and so on. Can be rescued in time.
3, cold and warm
After birth, piglets should be wiped dry to prevent body temperature from being excessively distributed, and be placed in a suitable incubator for piglet temperature. (1 day old 32--35 degrees. 2-2-3 day old 32--30 degrees. 3--7 day old 28--30 degrees) with a heat lamp. The distance between the piglet and the lamp should be more than 40cm to prevent the piglets from being burned.

prompt:
After the piglets were born, they were given oral gentamicin before colostrum, and 0.5-1 ml of sodium selenite was intramuscularly injected into the ear. After 3 days of iron supplementation, 7 selenium. 14, 21 days, respectively, iron, selenium.
6, disinfection, prevention of diarrhea.
In order to cut off the contact between piglets and pathogens, the sows should be sterilized before they enter the delivery room, cut off the umbilicus, cut the teeth, and break the tail.
