1. There are a large number of pigs and a certain number of sow farms. For the sowing period of sows, they should be planned and relatively concentrated in order to facilitate mutual trust of piglets. Otherwise, the number of farrowing pigs is excessive. However, the number of litters of the I sows is too few, the relative long period of time during the litter, and it is difficult to set up piglets; the adoption of concentrated litter by batch, not only can facilitate the fostering of piglets and sows and children, but also can make a few litter size distribution Bring a few sows. 2. Don't prematurely disconnect the umbilicus from piglets to avoid bleeding. The umbilicus should be cut off 10 minutes after the piglet is born. 3. Some primiparous sows have a violent temperament and give birth to one or two piglets that have just been born. One or two piglets that have just been born can be placed in a nursery basket. After the sow has produced more than seventy-eight piglets, the sows are placed together with the sow's abdomen. At the same time, the confinement workers should gently sow the sow’s The breast is adapted to breastfeeding and is also conducive to sow farrowing. 5 ml of chlorpromazine hydrochloride injection (50 mg) can be given intramuscularly to the sow. 4. The sense of smell of the pig is very sensitive. When the sow smells the smell of the piglets it produces, it will bite the foster piglet. When the sow is fostered, the most convenient way is: the foster piglet and the foster mother piglet are mixed in the nursery basket. About hours, the smell of piglets is the same. When nursing, the breeder also pays attention to careful observation to prevent the foster piglet from being harmed by the sow. 5. When fostering piglets, let the foster piglet raise enough colostrum. 6. Where the sow squeezing the piglet is usually at the corner of the wall. In this case, a larger piece of waste brick can be placed on the corner of the corner, or bricks can be placed on the corners of the box with a square of 20 cm in width and height. Not easily crushed. 7. In the litter of the newborn piglet, the grass should not be too much, because the newborn piglet is weaker, and the walking is unstable. Excessive bedding will cling to the piglet and it will be easily crushed by the sow. 8. Piglets less than one week old after birth should be given drops of oxytetracycline once daily, which is good for preventing diarrhea. Prescription: 1 gram of terramycin powder is dissolved in 100 ml of cold boiling water, and 3 ml of drops are taken per head per day. 9. Newborn piglets should be treated early. The route of administration is preferably oral, and drugs that can maintain high concentrations in the intestine and are rarely absorbed, such as streptomycin, kanamycin, and gentamicin, should be used. 10. The newborn piglet has a soft skin, and it will burn too long in the sunny sun. It will cause sunburn to the skin. Attention should be paid to it. 11. Some young piglets that are younger than the age of the day are swollen by sows or other reasons. Bubbling occurs on the body surface. Do not puncture the water immediately because the affected area will continue to have blisters. Repeated release of water, to promote the loss of nutrients in tissue fluids, will affect the growth of piglets, it is better to let it be natural, to be slowly absorbed by the tissue; or to be discharged when the age is large, and try calcium intravenously to reduce leakage Liquid. 12. Suckling piglets are susceptible to "iron deficiency anaemia". It is advisable to give an intramuscular injection of 100 mg of iron dextran injection to each piglet between 3 and 5 days after birth. 13. Sow should be fed less during the first week of the sow, and then increase the amount of feed from the 15th day after birth; piglets fed 5 to 7 days of age, can reduce the incidence of blight. 14. Within 3 to 5 days after the piglet is castrated, the breeder should carefully observe the suckling, feeding, and activity of the piglet, find an abnormality, and immediately perform the diagnosis and treatment. 15. When the piglets are around 1 month old, the farmer should spray 2% trichlorfon solution on piglets, sow body surface and pigsty wall at noon on sunny days to prevent piglet rickets. 16. In the first week before weaning, we should gradually lower the sow's feeding standard and reduce the sow's feeding amount so that the milk is reduced to a small amount, so that the separated piglets are gradually weaned. After weaning, a certain amount of coarse material should be added to the piglet feed, and the amount of feed should be controlled. After 10 days, gradually increase the amount of feed and reduce the amount of coarse material. These measures will help reduce the occurrence of diarrhea and edema disease in weaned piglets.
