2001 Breeding Season Crisis: Many Mares Losing Foals; Links to Related Stories

Two "syndromes" of unknown origin that began in late April are causing Central Kentucky farms to lose an excessive number of foals and fetuses. The first syndrome results in what broodmare owners know as "red bag," or premature placenta separation. The placenta comes out before the foal, often causing the foal to suffocate if the birth is unattended. The second syndrome was discovered a short time later, when veterinarians began to perform 60-day ultrasound fetal checks and found many mares either were not pregnant or in the process of ending their pregnancies. Some farms have experienced losses from 25-75% of next year's foal crop. There is no evidence the problems are slowing down.

Foal Loss Outbreak of 1980 Eventually Discounted as 'Artifact Epidemic'

An outbreak of early-term fetal loss in 1980 was eventually discounted by researchers as an "artifact epidemic" caused by earlier than usual examinations. Still, that outbreak now is viewed by many as similar in nature to the current syndrome that many Central Kentucky farms are experiencing. According to experts such as Dr. David Powell of the University of Kentucky Gluck Equine Research Center, the current problem is much more widespread than in 1980.

Epidemiologist Q&A on Excessive Foal Losses

University of Kentucky Diagnostic Lab Seeking Answers About Foal Loss

The director and staff of the University of Kentucky's Livestock Disease Diagnostic Laboratory have been working long hours conducting necropsies and running tests in an attempt to find answers to the questions raised during the ongoing losses of fetuses and foals in the state. While there hasn't been time yet to compile official numbers of incoming horses for testing, more than 60 have come on some days. The normal number of incoming abortions per day at this time of year is five to six, with a little higher number per day of dead foals.

Kentucky Farm Managers, Vets To Meet About Foal Loss

The meeting will begin at 5 p.m. (EDT).

Excessive Foal Loss Great Concern to Central Kentucky Farms

Two "syndromes" that began near the end of the third week of April are causing Central Kentucky farms to lose an excessive number of foals and fetuses due to an as yet unknown cause. The first syndrome results in what mare owners know as "red bag," or premature placenta separation where the placenta comes out before the foal, often causing the foal to suffocate if the birth is unattended. The second syndrome was discovered around May 1 when veterinarians began routine 60-day fetal checks and discovered that many mares either were empty (not pregnant), or were in the process of losing their pregnancies. Some farms have experienced losses ranging from 25-75% of next year's foal crop. And there is no evidence that this problem is slowing down.

Sales Prepping Yearlings

As spring moves into summer, the primary focus of activity on many breeding farms is preparation of yearlings for sale. There isn't much scientific research on exercising horses at that young age, yet many farms are using forced exercise to make these youngsters look like little athletes rather than the gangly teenagers they are. While it is good that ...
