Hello and thank you for visiting the Awassi Sheep blog. This blog is dedicated to the history, genetics and breeding of Awassi fat tail sheep. I'm Andy Karras a fourth generation sheep breeder and owner of Karras Farm in North Carolina. We specialize in Awassi Sheep, Assaf Sheep and East Friesian sheep. Karras Farm was the very first to sheep breeder to import the highly desireable Awassi Fat Tail Sheep into the United Sates.
Nasal Bots are the adult stage of the female fly. They lay tiny eggs on the nose of sheep, then the larvae crawl up the nose and into the sinuses where they mature into large larvae. Eight to ten months later the bots come out of the nose, drop to the ground and develop into flies. While in the sinus, the larvae may cause severe irritation. Ivermectin products are most effective against the larvae stage but sheep may be repeatedly affected as new larvae migrate to the sinuses.
