Placentitis, an inflammation of the placenta caused by bacteria such as Streptococcus equi subspecies zooepidemicus, is one of the leading causes of foal death. It's challenging to treat, and researchers are still trying to identify effective therapies, particularly antibiotics. Currently, many practitioners administer the antibiotic ceftiofur crystal...
Some equine diseases come and go with little impact on the horse industry as a whole. Others affect only local or state industries when they rear their ugly heads. But when a disease has the potential to shutter the global horse breeding industry, controlling it becomes crucial. One of those diseases is equine viral arteritis (EVA). Fortunately, veterinar...
An infectious equine disease is bad news no matter what language you speak or which country you call home. But between countries, regulatory bodies, and animal health professionals, there often remains a difference in perspective when it comes to handling these diseases.
Foals have seemingly endless energy, darting around their fields, playing with their pasturemates, and recharging with a quick nap and a drink from Mom. But, occasionally, a foal develops a health problem that zaps that energy and leaves him in a collapsed heap, looking sickly and vulnerable. What should you do if this happens to your foal?
From equine herpesvirus and influenza to strangles and coronavirus, infectious diseases can cause quite a stir in the horse industry—quarantines, canceled competitions, and, in some cases, even horse deaths or the threat of human infection.

Somewhere between when the birthing process begins and when the long-legged foal takes his first wobbly steps, he transitions from an unconscious fetus to a conscious horse. And while owners might just be happy to see their new arrival waking up to the world, researchers now believe that the fetal consciousness transition could have a significant impact o...

Approximately 20,000 mares are bred in Kentucky each year, which means that it is literally “raining foals” in the spring, as long as things go as planned. Unfortunately, late-term abortions and even abortion storms can occur, resulting in massive economic and emotional mayhem.
When a horse contracts a disease, the owner or caretaker usually focuses solely on getting the horse healthy again and protecting others on the farm from illness.
