Fact #1Gastro-intestinal parasites, A.K.A. Worms, are the primary health problem affecting sheep and goats in warm, moist climates.
Common names: barber pole, wire worm, large stomach worm.
Blood-sucking roundworm that pierces the mucosa of the abomasum, causing blood and protein loss to the host.
It needs warm (60°F), moist conditions to complete its life cycle.
Pasture is the primary mode of transmission.
It is estimated that 80% of the worm larvae is found in the first two inches of grazing vegetation.
Young animals and highly stressed adults are most vulnerable to its effects.
It has a short life cycle.
On average 2 to 3 weeks
As short as 7 days
It has a direct life cycle.No intermediate host is required.
It is a prolific egg producer.
It has been estimated that 20% of the flock is responsible for 80% of the egg output.
Loss of body condition
Anemia (pale mucous membranes)
Edema – “bottle jaw”accumulation of fluid under jaw
Only 3 drug families!
Deworm every month
Deworm before breeding, before lambing, before shows, etc.
Deworm because you haven’t done it lately.
Deworm because you’re handling the sheep for another reason.
Deworm to prevent problems.
Deworm everybody, all the time.
Deworming to get rid of all the worms.
Deworm because you’re a good manager.
Integrated Parasite Management (IPM)
Management of grazing height
Alternative forages and treatments
Within and between breed selection
Fecal egg analysis
Proper anthelmintic use
A novel system for monitoring barber pole worm infection in small ruminants.
Developed in South Africa due to the widespread emergence of drug resistant worms.
Originally developed for South African sheep, but has been validated for sheep and goats in the United States.
Named for its originator Dr. Francois “FAffa” MAlan CHArt
A color eye chart for evaluating clinical anemia in sheep and goats.
Anemia is the primary symptom of barber pole worm infection.
FAMACHA© enables the selective deworming of clinically parasitized animals, while leaving healthy animals untreated.
Reduces the number of animals that are dewormed (though some animals may need treated more often).
Saves you money on drugs
Reduces chemical/drug use
Reduces selection for drug resistant worms, by increasing refugia: worms not exposed to drug(s).
Identifies susceptible and resistant animals in the flock (parasite resistance is moderately heritable).
Always use the card.
Don’t use a copy of the card.
Replace the card every year (colors fade).
Check often enough (e.g. every 2-3 weeks during the “worm” season).
Have an easy way to handle your animals.
Test for drug resistance. You must know if an anthelmintic is effective!
Eliminate the need for other parasite control practices.
Save you time.
You may deworm less frequently, but you’ll spend more time checking your animals.
Help with other potential parasite problems
Other GI worms
FAMACHA© is not a magic bullet. It is another tool.
84 Katahdin and Katahdin crossbred lambs from a sire comparison study (Suffolk, Texel, and Dorper sires).

FAMACHA is distributed under the auspices of the South African Veterinary Association.
U.S. distribution is made through the SCSRPC via the laboratory of Dr. Ray Kaplan (University of Georgia)
FAMACHA cards are only to be sold directly to veterinarians.
Producers are required to take an approved training in order to receive a card.
