A 12-year-old Quarter Horse mare displaying severe neurologic signs tested positive for non-neuropathogenic (EHV-1).
Diseases reported include African horse sickness, influenza, EHV, EIA, rabies, and more.
Four horses from the Oldham County facility have tested positive for neurologic EHV-1 so far.
Meanwhile, movement restrictions on horses that have recently been at the track are being implemented.
Four horses have now tested positive for EHV at the New Orleans, Louisiana, racetrack.
The facility was released from quarantine following repeated negative EHV-1 testing on resident equids.
This potentially fatal infectious disease continues to challenge the horse industry, but our experiences are teaching us how to prevent its spread.
Mares had higher pregnancy rates per cycle as sperm numbers and number of inseminations per cycle increased.
A 2-year-old Thoroughbred gelding stabled at the Louisiana track was euthanized after developing neurologic signs.
Foal size (and, indirectly, sex) appear to contribute to dystocia, especially among mares in New Zealand.
Scientists tested whether estradiol-17B, progesterone, alpha fetoprotein, and/or serum amyloid A could predict abortion.
Some quarantines remain in place at the Los Angeles Equestrian Center, in Los Angeles County, and in Inyo County.
Spring is an exciting time for many breeders, as it likely marks the last trimester of their mares’ pregnancies. Due to the rapid changes that occur in the last few months of gestation, it is imperative that owners monitor mares closely.
Meanwhile, no new cases have been confirmed in the unrelated Inyo County incident.
The codes are a guide to preventing and controlling equine diseases that could threaten the breeding industry.
Tests are being run on another Los Angeles County horse and an affected Inyo County horse developed neurologic signs.
