Researchers investigating mare reproductive loss syndrome (MRLS) have made a causative link between the ingestion of live eastern tent caterpillars in pastures and MRLS-type abortions.
"In the final analysis, we do not understand this disease," said Dr. Bruce Webb, an entomologist at the University of Kentucky who has been a leading researcher into the problem of Mare Reproductive Loss Syndrome.
A reproductive study examining the breeding records of four Central Kentucky Thoroughbred farms reveals that nearly 30% of mares bred between early February and early May 2001 who were declared at one time to be in foal, lost those foals.
