Porcine reproductive and respiratory syndrome (PRRS) is a viral disease that causes a decrease in reproductive performance in breeding animals and respiratory disease in pigs of any age. PRRS is the most economically significant disease affecting swine production in the world today.
SOUTH KOREA - The Fourth Asian PRRSpective opened yesterday in South Korea's Jeju Island to update Asian pig farmers on the latest scientific research on PRRS and effective solutions in keeping it under control.
Porcine ileitis, a common disease also known as Porcine Proliferative Enteropathy, is caused by the bacterium Lawsonia intracellularis. The costs of the disease can be high and have been projected to exceed US$22 per affected pig and production losses can be significant even if physical symptoms aren’t apparent, writes JoAnn Alumbaugh.
Sow herd vaccination, i.e. against influenza and other viruses that can be transferred from the sow’s blood stream through the uterine blood supply thereby breaking through the uterine barrier: PRRS-virus, Circovirus, Parvovirus
Early and excessive iron supplementation can negatively influence health
Piglets are born with minimal iron-reserves (40 mg). This low iron concentration is a natural defence mechanism directed at combatting bacterial infections during and after birth.
Sow milk provides piglets with about 1 mg Iron/day. With a daily need of about 7 mg there is only sufficient iron for about 4 to 5 days.
