Critical Mare and Foal Care

with Krista Estell, DVM, Diplomate ACVIM – Clinical Assistant Professor of Equine Medicine Foaling season is the most highly anticipated time of the year for professional horsemen and backyard breeders alike! In most cases, foaling is a joyous event that goes as expected, however, foaling can quickly turn problematic and both the mare and the foal can be at risk. Risk factors can be detected by comprehensive examination of the mare and fetus including ultrasonography, ECG, and blood tests. For high-risk pregnancies, including mares subject to placentitis, post-partum hemorrhage, dystocia, or foal complications such as neonatal dysmaturity or septicemia,...

EHV-1 Reported in Maryland

This past weekend, several reports citing that the Maryland Department of Agriculture placed three Maryland farms on hold due to exposure to equine herpesvirus-1 were circulating on social media. Horses from three farms, located in St. Mary’s County, Calvert County, and Montgomery County, attended a show in Virginia the weekend of February 24-25, where the exposure to EHV-1 occurred. According to the Maryland State Veterinarian Dr. Michael Radebaugh, “as of this morning no horses at the Calvert and St. Mary’s County locations have shown any signs of EHV-1.” Dr. Radebaugh stated that, “as long as everything continues in the right direction, both farms will have their hold orders removed this weekend.” The Montgomery County farm has one horse with a fever that tested positive for the wild strain of EHV-1, but according to Dr. Radebaugh is not currently showing any neurological symptoms. The hold order on the Montgomery County farm has been extended. As more information is provided by the Maryland Department of Agriculture, The Equiery will keep you...

Snotty Nose? CTs are a game changer for dental and sinus diagnostics

with James A. Brown, BVSc, MS, Diplomate ACT, Diplomate ACVS, Clinical Assistant Professor of Equine Surgery Nasal discharge in horses can be both alarming and frustrating. Pus coming from both nostrils can indicate guttural pouch or lower airway infection, whereas smelly pus coming from one nostril is commonly associated with sinusitis and dental infection related sinusitis. It is important to have a veterinarian exam the horse quickly to determine the cause and to insure there is not a contagious situation such as strangles, which can impact an entire barn. During the exam, a veterinarian will do a palpation of the head for swelling, an oral exam and perhaps an upper airway endoscopy. The vet may also assess the surface of the teeth for abnormalities such as fractures, caries of the infundibulum, and open pulp chambers, which can be accompanied by infection. Despite a thorough exam, sometimes the reason for sinusitis may not be evident and imaging of the head will be the most expeditious means for accurate diagnosis. The complex nature of the horse’s sinus compartments, combined with opacity (whiteness) from fluid, often make radiographs difficult to interpret. Without a diagnosis, horses are often treated with antibiotics and lavage of the sinus compartments. Resolution of symptoms sometimes occurs but in many cases, after treatment is discontinued the problem returns, which can be frustrating. For such horses with sinusitis or...

According to MJC, Sal Sinatra, President and General Manager of the Maryland Jockey Club, said that a horse who shipped to Laurel had tested positive for the EHV-1 virus. The horse has been removed from the grounds but the barn he was stabled in has been placed under quarantine. The horse will be tested off property again Tuesday. If the horse tests negative restrictions will be lifted immediately. If he tests positive again, the restrictions will remain in place until January 30. “We’re asking horsemen in other states and at training centers to check their policies before entering,” Sinatra said.
