• Ivermectin is the first in a series of antiparasitic agents derived from the avermectin family of compounds. The avermectins are highly active, broad-spectrum antiparasitic agents isolated from fermentation of the soil organism Streptomyces avermitilis.

I. Breeding Animals:

At the time of initiating any parasite control program it is important to treat all breeding animals in the herd. After the initial treatment, use IVOMEC Injection regularly as follows:

Sows

Treat prior to farrowing, preferably 7-14 days before, to minimize infection of piglets.

Gilts

Treat 7-14 days prior to breeding. Treat 7-14 days prior to farrowing.

Boars

Frequency and need for treatments are dependent upon exposure. Treat at least two times per year.

II. Feeder pigs:

All feeder pigs should be treated before placement in clean quarters. Pigs exposed to contaminated soil or premises may need retreatment if reinfection occurs.

Note:

1. IVOMEC Injection has a persistent drug level sufficient to control mite infestations throughout the egg to adult life cycle. However, since the ivermectin effect is not immediate, care must be taken to prevent reinfestation from exposure to untreated animals or contaminated facilities. Generally, pigs should not be moved to clean quarters or exposed to uninfested pigs for approximately one week after treatment. Sows should be treated at least one week before farrowing to minimize transfer of mites to newborn baby pigs.

2. Louse eggs are unaffected by IVOMEC Injection and may require up to three weeks to hatch. Louse infestations developing from hatching eggs may require retreatment.

3. Consult a veterinarian for aid in the diagnosis and control of internal and external parasites of swine.
