Surgical Options for Managing Roaring in Horses

You might not be able to see a roarer from a mile away, but you sure can hear them. Horses with recurrent laryngeal neuropathy (RLN, often referred to as roarers due to the sound they make breathing) frequently require surgical intervention to both reduce the noise produced during exercise and to increase the amount of air they can take in while working.

Effects of Selenium Source on Mares and Foals
