What about milk fever? or this......
Feeding the Pig During Lactation. Sows’ milk does not contain enough iron for baby pigs. Iron must be given to pigs within their first 3 or 4 days to prevent anemia. Pigs can be supplied with iron by giving them clean sod (not from a hog lot), iron injections (iron dextran in the ham or heavy neck muscle), or iron compounds mixed with other minerals which pigs can eat. When pigs are about 1 week old, start feeding them a prestarter (about 20% protein) or starter feed in a shallow pan.
The prestarter is usually more acceptable and pigs will start to eat earlier. It is used only to get pigs to start to eat. A little prestarter or starter feed mixed with some clean sod will often start pigs eating earlier.
After pigs start to eat, switch to a starter feed (about 18% protein) and feed this until the pigs weigh 25-30lb. At this time, the ration can be switched to a lower cost (16%) pig grower feed. Clean, fresh water should be available to pigs even before they start to eat dry feeds. Clean, fresh water should be available to pigs even before they start to eat dry feeds.
Controlling Health Problems. Sows should be observed carefully during the first few days after farrowing. Lack of appetite, listlessness, and failure to respond positively to nursing activity of the pigs indicate need for corrective treatment. Prevention of these conditions will decrease incidence and severity of the MMA syndrome.
If MMA is prevalent, a prevention and treatment program should be developed through veterinary consultation and by management programs. The same is true for diseases such as atrophic rhinitis, transmissible gastroenteritis (TGE), parvovirus (SMEDI) and mycoplasma pneumonia. Checking for normal bowel activity and use of a rectal thermometer to detect fever can pinpoint early need for treatment.
