With MRLS Outbreak, 2000 Was Year of Loss For Breeding Industry

The worst health problem to hit the Thoroughbred industry since CEM and EVA occurred during the spring of 2001.

Some foals were born compromised and later died. The second situation was early fetal loss.

Recommendations Forthcoming From Mare Reproductive Loss Survey

The survey of 133 Central Kentucky farms was designed to identify risk factors, not causes, of mare reproductive loss syndrome, said Dr. Roberta Dwyer of the University of Kentucky Gluck Equine Research Center.

Mare Reproductive Loss Survey Confirms Some Beliefs; Belies Others

Results from the survey of 133 farms in Central Kentucky regarding the early fetal loss and late-term abortions that occurred this spring substantiated the preliminary ideas held by researchers and veterinarians this spring.

Study: Growth Rates Not Affected by MRLS

While mare reproductive loss syndrome has had a devastating effect on in-foal mares in 2001, a just-released study indicates it had no affect on the growth rate of foals of 2000 and 2001 raised on Central Kentucky farms and foals of 2001.

A Kentucky veterinarian who specializes in mare reproduction, fetal ultrasound, and fetal sexing has studied pregnancy videos 1996 and 1998 and foal production the following years and has found that some degree of cloudiness in chorionic or amnionic fluid did not necessarily mean the mare would lose her foal or she would have an abnormal foal.

Researchers Zero In on Cyanide as Cause of Foal Loss Syndrome

Researchers at the University of Kentucky Gluck Equine Center have made significant progress in their quest to find the cause of the Mare Reproductive Loss Syndrome. According to reports presented Thursday during an informational forum at Keeneland, black cherry trees located in close proximity to horse pastures are the primary source of the cyanide that was detected in tests of dead foals and fetuses from mares that aborted.
