    Central Kentucky Abortion Rate Appears Normal

    Mid-gestation abortions have generated concern in Central Kentucky, but according to officials, the 50 fetuses received in the last five months by Kentucky's Livestock Disease Diagnostic Center in Lexington do not represent a significant increase over past years.

  • The Caterpillar Is Innocent

    <i>By Jenny Taylor</i> -- The culprit for MRLS was an unseasonable weather-induced pasture change, which caused pregnant mares to have an acute nitrogen overload, and subsequent ammonia-induced abortions.

  • MRLS Monitoring Stepped Up, But No Problem Found

    Pathologists at the Kentucky Livestock Disease Diagnostic Center in Lexington noticed that a few more fetal losses were being seen than was usual during August, September, and October. That prompted increased surveillance and reporting, and meetings by the Kentucky Association of Equine Practitioners committee that was formed during the mare reproductive loss syndrome crisis of 2001.

  • Drop in Kentucky Foal Crop Not as Large as Projected

    The Jockey Club is predicting that the 2002 foal crop in Kentucky will be about 2,000 less than last year's figure, primarily because of mare reproductive loss syndrome, but the projected decrease isn't as large as earlier estimates.

  • Preliminary Results Find Caterpillars Cause Late-Term Abortions

    The University of Kentucky College of Agriculture has released preliminary results from a collaborative project involving the UK Livestock Disease Diagnostic Center, the UK Department of Veterinary Science, and the Hagyard Davidson McGee Equine Hospital.
