A research project begins well before the experiment starts. That was the case of the recently completed collaborative effort at the University of Kentucky that associated the Eastern tent caterpillar and its frass (excrement) and Mare Reproductive Loss Syndrome (MRLS). Work on that project began last fall, even before funding was finalized.

Early test results of a University of Kentucky College of Agriculture study appear to show a correlation between eastern tent caterpillars, their waste--called frass--and foal loss in mares exposed to both.
The University of Kentucky issued an advisory Friday regarding the eastern tent caterpillar, which is still regarded as a primary risk factor associated with mare reproductive lose syndrome.
MRLS took the lives of some 3,500 foals in Central Kentucky, but a recent study indicates it did not affect the quality of life for surviving foals.
Weather forecasts for the evening of April 24 in Central Kentucky have prompted University of Kentucky scientists to advise farm owners to temporarily restrict horses from eating pasture grass. The advisory is because of mare reproductive loss syndrome (MRLS), which hit at this time last year after an unusual weather pattern.
The rate of reduction in foal losses in Kentucky is slowing, but it is still staggering. The latest figures from The Jockey Club show 32.4 percent less foals dropped in Kentucky this year through April 3 compared with a year ago.
A report detailing research of early fetal losses due to mare reproductive loss syndrome points to pastures as the suspected source of the syndrome.
On Thursday the press viewed soil and plant testing that is part of the monitoring program created in response to Mare Reproductive Loss Syndrome.

By Ray Paulick -- As live foal reports from The Jockey Club confirm the full impact of last spring's Mare Reproductive Loss Syndrome, the breeding industry continues to be frustrated by uncertainty over the cause of the problem.
Following a recent meeting of researchers and veterinarians, there was a new optimism that Mare Reproductive Loss Syndorme and other syndromes could be solved with the clues that have been, and will be, put together by these researchers and through the input of clinicians.
For the first 64 days of the year, The Jockey Club has reported a significant drop in the number of Kentucky-bred foals. The decline was expected as a direct correlation to mare reproductive loss syndrome.
The cause or causes of mare reproductive loss syndrome are still a mystery, but that hasn't lessened interest in the topic. During an informational session Monday, new questions were raised about circumstances surrounding the outbreak during last year's breeding season.
Gross purses rose 3.6% and pari-mutuel handle increased 1.6% in the United States for 2001, setting records in both catagories, according to the 12th edition of "The Jockey Club Fact Book," released online today.

Kentucky farm managers and owners are taking steps to prevent the reoccurrence of mare reproductive loss syndrome while fervently hoping last year's devastation was a one-shot deal.

The worst health problem to hit the Thoroughbred industry since CEM and EVA occurred during the spring of 2001. What was grouped by the industry under the heading of mare reproductive loss syndrome actually was two reproductive situations. The first was the loss/abortion of late-term or at-term gestations. Some foals were born compromised and later died. The second situation was early fetal loss.
