Karras Farm specializes in breeding East Friesian Dairy Sheep. We have been in the dairy sheep business since the late 1800's starting in Greece. Four generations later we are still commited to breeding the highest quality and genetically pure East Friesian Sheep in the world. In 1994 we moved our operation to North Carolina with the same focus of excellence to our animals and customers.
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.
The adult stage of this parasite lives in the bile ducts in the liver of sheep.
A very small number can pose a detrimental effect on the host. Larvae hatch eggs passed in the feces, but they must be ingested by a snail to move to the next stage of development. Flukes are usually found in damp meadows or wetlands where snails are present.
Prevention can be directed at drying up wetlands or fencing sheep away from them. Two available medications, Clorsulon and Albendazole are effective if given after the first of January when the larvae have developed into adults in the liver. After 2-4 years of use the number of eggs and larvae on the pasture should be greatly reduced and pose little threat. Continued use of these medications is necessary to prevent resurgence.
Coccidiosis is an acute contagious parasitic disease spread between sheep through fecal contamination of feed or water. Strict sanitation and proper arrangement of feed/water containers will greatly reduce the probability of contamination. Lambs must be prevented from tracking manure into feeding areas. Coccidiosis in lambs can be very deadly. This parasite causes severe diarrhea, sometimes bloody, usually dark in color resulting in extreme dehydration or death.
We recommend frequent fecal checks to ensure healthy Coccidiosis free animals. At Karras Farm we feed our East Friesian dairy ewes and lambs pellet feed medicated with Deccox or Bovatec (lasolocid) continually to control Coccidiosis and improve feed efficiency. Ewes should receive this continually from thirty days prior to lambing through shortly after the lambs are weaned.
Have a wonderful Columbus Day and Thanksgiving to all our friends in Canada~
