Prevalence of L.intracellularis on Farms (AAEP 2011)

If someone had said "equine proliferative enteropathy" 10 years ago, chances are most horse breeders would have shrugged their shoulders and paid little mind. Today, however, many breeders are mindful of this still-emerging young horse disease caused by the Lawsonia intracellularis bacteria. Researchers have made great strides in comprehending m...

Humeral Stress Fractures and Return to Racing (AAEP 2011)

A stress fracture is a stress fracture, regardless of its location, right?

Dental Health and the Performance Horse

When searching for answers as to why an equine athlete's performance has suddenly declined, many owners and trainers will look for problems from head to toe. But one place they sometimes neglect to check is the horse's mouth, where many dental issues can cause a performance horse to work at a less than optimum level.

Developmental Dental Disorders in Horses

One of the most common aspects people consider when selecting a horse to purchase is the animal's conformation. Are his hocks too straight? Is his back strong? And are his pasterns too long? But some horses that look flawless on the surface could be harboring a developmental dental disorder, some of which could be dangerous and performance-limiting if...

Colic in Horses: When is Surgery Necessary?

When a horse is in the midst of a bout of colic, many owners wonder if their animal will need surgery to fix the problem. For those owners who have never experienced a referral to an emergency medical clinic for surgery or intensive care, understanding their veterinarian's decision on how and where to treat the colic can be confusing.

Wobbler Syndrome in Horses: An Overview

There are few things more enjoyable than watching a herd of young horses frolic around a pasture.
