Shoe horses long enough, particularly performance horses, and you’ll eventually run into a problem with interference. Two accomplished farriers — Marcus Lybarger of Venice, Fla., who also works in the Chicago area, and Tim Cable, who splits his time between Buffalo, N.Y., and Wellington, Fla. — shared their knowledge to help you meet the challenge.

A postmortem study examined the records of 241 horses at least 15 years old that died following admission to a veterinary teaching hospital over a 10-year period to investigate their causes of death, including the relationship to pituitary pars intermedia dysfunction (PPID).

Joint Injections Compared Joint injections using corticosteroids, hyaluronic acid (HA) or a combination of the two are commonly used to treat synovitis and arthritis in performance horses. In this study, researchers compared the efficacy of one type of corticosteroid (triamcinolone acetate, TA) with and without HA for the treatment of lameness, localized to one limb only that responded to a diagnostic joint block. Eighty horses of various breeds were enrolled in the study with follow-up at 3 weeks by re-examining the horses and 3 months by an owner questionnaire. No other medications were permitted during the first 3 weeks of follow-up.
