Fact #1Gastro-intestinal parasites, A.K.A. Worms, are the primary health problem affecting sheep and goats in warm, moist climates.
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.Haemonchus contortus
It has been estimated that 20% of the flock is responsible for 80% of the egg output.the barber pole worm CAN be difficult to control.
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.
Selective dewormingFact #4Regular deworming of every member of the flock is not A SUSTAINABLE PRACTICE.
Management of grazing height
Alternative forages and treatments
Within and between breed selection
Fecal egg analysis
Proper anthelmintic use
Selective dewormingFact #5Nowadays, worm control requires a more integrated approach.
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 CHArtWhat is FAMACHA©?
Anemia is the primary symptom of barber pole worm infection.
FAMACHA© enables the selective deworming of clinically parasitized animals, while leaving healthy animals untreated.What is FAMACHA©?
Saves you money on drugs
Reduces chemical/drug use
Reduces selection for drug resistant worms, by increasing refugia: worms not exposed to drug(s).What FAMACHA© does
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
Etc.What FAMACHA© doesn’t Do
FAMACHA© is not a magic bullet. It is another tool.
