A second foal has been confirmed as having died from mare reproductive loss syndrome (MRLS) in Florida, according to Dr. Dana Zimmel of the University of Florida's College of Veterinary Medicine.
At the industry-wide meeting on Thursday, May 10, Dr. Steve Jackson, an equine nutrition consultant and owner of Bluegrass Equine Nutrition, and Dr. Jimmy Henning, an extension forage specialist at the University of Kentucky's College of Agriculture, both mentioned that ergot or alkaloid types of toxins were being sought in the testing of pastures. In discussing the situation further with Jackson on May 11, he said that Merck's Veterinary Manual had a good explanation of ergotism in other livestock.
