LEXINGTON, Ky. - Early results from an ongoing experiment at the University of Kentucky have linked early equine fetal loss to caterpillars and their excrement, researchers reported Wednesday.
In clinical trials in Lexington, researchers announced that six of nine pregnant mares involved in the study lost their fetuses after exposure to caterpillar frass, or excrement, alone. Six of 10 pregnant mares aborted after exposure to large numbers of caterpillars and frass.
