Pathology in Practice

摘要

A 1.5-year-old second-parity Large Black X Tam-worth cross sow from a well-managed 20-sow, unvacci-nated, pasture-raised herd of pigs in upstate New York aborted a litter of 7 variably mummified near-term fetuses and stillborn piglets. This sow had nosigns of ill health other than abortion; it was housed in a group with 4 other sows and a 2-year-old Gloucestershire Old Spot boar. One of the stillborn piglets from this litter was submitted to the New York State Animal Health Diagnostic Center for necropsy; no placental tissue was submitted with the piglet. A second sow from this group had aborted a litter at the same late stage of gestation within the preceding 2 weeks; however, none of the fetuses were submitted for diagnostic investigation. No signs of ill health were reported for the rest of the herd. The referring veterinarian indicated that these pigs had access to corn standing in the field and that, because of recent wet weather, there was concern that mycotoxin contamination might be the cause of the abortions.
