Cattle:
Ivermectin 1% Injection should be given only by subcutaneous injection under the loose skin in front of or behind the shoulder at the recommended dose level of 200 mcg of ivermectin per kilogram of body weight. Each mL of Ivermectin 1% contains 10 mg of ivermectin, sufficient to treat 110 lb
(50 kg) of body weight (maximum 10 mL per injection site).

Swine: Ivermectin 1% injection should be given only by subcutaneous injection in the neck of swine at the recommended dose level of 300 mcg of ivermectin per kilogram (2.2 lb) of body weight. Each mL of Ivormectin 1% contains 10 mg of ivermectin, sufficient to treat 75 lb of body weight.

Recommended Treatment Program
Swine: 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 Ivermectin 1% injectable 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 a year.
Feeder Pigs
(weaners/growers/finishers)
All weaner/feeder pigs should be treated before placement in clean quarters.
Pigs exposed to contaminated soil or pasture may need retreatment if reinfection occurs.
Note
(1) Ivermectin 1% injectable 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 Ivermectin 1% 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.
