Selective deworming has been proven to prevent further development of dewormer resistance in a number of research studies. It works because the resistant worm eggs produced by resistant worms in de- wormed animals will have non-resistant worms to mate with from the animals that were not dewormed. The pool of non-resis- tant worms is called refugia (in refuge from the dewormer).
The five point check© includes FAMA- CHA©, checking for bottle jaw, body con- dition, diarrhea and nasal bots (which are only present in sheep, therefore, look at hair coat on goats). The
wormx.info website has considerable information on FAMACHA©. Bottle jaw is the double chin appear- ance of wormy animals due to fluid collect- ing under their jaw. Body condition is important in that wormy animals are often thin due to worms.
Many types of worms that do not cause anemia cause diarrhea. The hair coat of a wormy animal is often rough and dull. By checking these indicators, it can be dete- mined if an animal needs to be dewormed. Traditionally, we dewormed all animals used for milk or meat around the time of kid- ding. We know that this practice can promote the development of dewormer resistance. The Australians recommend deworming the first-time kidders, eldest and all animals car- rying twins or more. The does pregnant with singles are not dewormed to provide refugia and slow the development of dewormer re- sistance. When you do not ultrasound, you could leave animals that have not had a worm problem in the past not dewormed. What do you deworm with? There are only two dewormers approved for use in goats, fenbendazole (tradename Panacur or Safeguard) and morantel tartrate (tradename Rumatel). All other dewormers are off-label, which means that you have to get veterinary approval for their use. There is a chart on the
wormx.info website for correct dose and withdrawal interval. This is the number of days or hours after a dewormer is admin- istered before the animal can be used for milk are meat. There are three classes of de- wormers available for use on goats in the U.S. If you live in a warm humid area, you have to know more about your worm farm than your goat farm if you are going to suc- ceed at raising goats. You are going to have to spend some time on planning for worm prevention and the management to carry out those plans if you plan to stay in the goat business very long.

FAMACHA© is checking the color of the mucous membrane of the eye against a color chart to determine if the animal is anemic and needs to be dewormed. You can get trained by a local vet, county agent or can get online training from

wormx.info website for train- ing opportunities).
