Using Ivomec (Ivermectin) to control lice in goats

At one time or another, most people who raise angora goats find signs of biting or sucking lice on their angora goats. It strikes goats of all ages, nannies, billies and wethers equally. The first thing one might notice to indicate goat lice is a goat rubbing against fences or barns, or nipping itself. Patches of hair may be rubbed out or appear to be shedding from the goat. The biting and sucking lice increase in number and size. As the condition gets worse, the angora goat rubs, scratches and nips more. The animal needs immediate attention, as it is very uncomfortable, and might even begin to lose weight, or cause raw spots from rubbing that could get infected. The lice will spread to your other goats and pets, even cats and dogs. Don't wait till this happens! The minute you see signs of lice, take action. The first step is to call your veterinarian and describe the symptoms, age and condition of your goat, including any details that might be important, like the goat's age, whether it is pregnant or lactating, whether the milk is used for human consumption, or the goat for meat. Describe any other conditions you might observe.

If your vet is an overworked, country vet who doesn't have time to deal with your lice problem, here are some suggestions:

Shear the affected goat thoroughly. Burn the fleece. Remove goats from barn, or pen. Go to your feed dealer, or get a catalogue from a livestock supply company like ValleyVet, or Premier 1, or Jeffers Livestock Supply. Buy a product made specifically for killing lice, perhaps that has Permethrin in it. Mix in a spray bottle according to directions. After removing all feed and bedding (burn it), then spray the barn or goat pen, before putting down clean bedding. Clean the troughs and hay mangers.

You might also find a powder product for lice to sprinkle around. Some people use a lice powder that is made for chickens.

After angora goat has been shorn, wash him with Permethrin solution, or powder.

Buy a lice killing product like 1% Ivermectin Cattle injectible, that speaks of treating biting and sucking lice. Draw about 2 or 3 CCs into the syringe, remove the needle, and squirt the solution well into the goat's mouth. Repeat in ten days. This should do the trick.

Usually, about every three months, and especially after shearing, I treat the angora goats with Ivomec for lice, even if I do not see any symptoms. It also takes care of a variety of other parasites and worms, though you may want to rotate your wormers, if your vet thinks it is desireable.

Remember, if you plan to use the goats for slaughter, or for milk, be sure to follow withdrawal instructions on the medication.

Also, be sure to thoroughly launder, burn, or bury your goat barn clothing. I usually wear some old thrift store special when working around animals, and throw the clothes away or burn them afterwards.
