Very little scientific research has been done in the way of comparing the effectiveness of equine vaccines. However, several researchers have been hard at work over the past few years trying to determine if any particular U.S.-registered equine vaccines had advantages over others.

“For athletic horses, energy is the most important nutritional consideration,” said Geor. “Energy is not a nutrient per se, but rather a measure of a feed’s potential to fuel body functions.”

Junctional epidermolysis bullosa (JEB) is an inherited disease that causes skin lesions over pressure points of the body in newborn Belgian foals and results in large areas of skin loss. The disease is a lethal condition and affected foals typically are euthanized shortly after birth.

With chronic laminitis, O’Grady explained that toe-downward rotation of P3 (the coffin bone) often occurs, which results in more pressure placed on the solar corium (the highly vascular tissue from which the sole grows) under the apex of P3. This pressure can disrupt blood flow, altering the rate and even the direction of sole growth.

Results of a study from the University of Pennsylvania’s New Bolton Center suggest that there is a high chance that a horse can return to racing after surgery for laryngeal hemiplegia (partial or complete paralysis of the larynx, also called roaring) or arytenoid chondritis (inflammation of the arytenoid cartilages resulting in paralysis).

If there are any two words that can cause a foaling operation’s manager to shudder, they are probably “Rhodococcus equi,” since the bacterium is considered the most common cause of severe pneumonia in foals.

“Indications to evaluate this area include respiratory noise and a persistent cough, often along with poor performance,” he said. “When the cough is observed while the horse is eating or when bitting up, this is pathognomonic (is indicative of a specific problem; in this case, subepiglottic ulceration).
