About 100 horses at EquiTransfer, an embryo transfer facility in Marion County, Fla., have died just in the past week due to an unknown illness that caused the horses to exhibit neurological problems and then collapse, according to The Gainesville Sun.
Although not confirmed, the owners, Jose Davila and Francis Ramirez, both veterinarians, believe the cause was contaminated hay. The suspect hay arrived Sept. 26 and 27 and by Sept. 28, the first few horses became sick, the newspaper reported. The couple did not say who they bought the hay from, but that EquiTransfer is the supplier’s only customer.
Samples from the dead horses, as well as from the hay, have been sent to toxicology labs.
