How to treat lice in goats?
There are two types of chemical treatments for goat lice: topical and systemic. Treatment depends on the type of lice present. Biting lice can be controlled with a topical treatment (a liquid or powder applied directly to the skin) while sucking lice may be controlled topically but usually require a systemic treatment (oral or injected). Almost all treatments used to control goat lice are “off-label,” meaning that the medication is not specifically labelled or approved for goats, nor is a dosage given on the package. For that reason, we cannot recommend treatment. A veterinarian must be consulted to advise on the off-label use of medication. You may also find an experienced herdsman or goat mentor who can share their parasite management practices with you. As with all medication, care must be taken for dairy and meat animals to respect withdrawal times and not harvest meat or milk while the medicine is still present in the system. For pregnant and very young animals, some medications may not be safe to use. Because of the drug-resistance of parasites in goats, is important to use a chemical targeted at the specific parasite. While a chemical dewormer may be effective, if the lice can be eliminated topically by using an insecticide, it is preferable.
