For the treatment of infections and infestations caused by the following internal and external parasites in growing swine:

Gastrointestinal roundworms: Ascaris suum (adults and fourth stage larvae), Ascarops strongylina (adults), Hyostrongylus rubidus (adults and fourth stage larvae) and Oesophagostomum spp. (adults and fourth stage larvae).

Kidney worms: Stephanurus dentatus (adults and fourth stage larvae)

Lung worms: Metastrongylus spp. (adults)

Lice: Haematopinus suis

Mites: Sarcoptes scabiei var. suis

Level of medicating ingredient in a complete feed

2.0 mg/kg (0.0002%) of ivermectin in the complete starter, grower and finisher feed.

Directions for use in a complete feed

Feed this medicated feed to appetite as the sole ration for seven (7) consecutive days.

Warning

  1. Treated pigs must not be slaughtered for use in food for at least five (5) days after the latest treatment with this medicated feed.

Caution

  1. Since the effect of ivermectin on mites is not immediate, care must be taken to prevent transfer of infestation to untreated animals or clean facilities. Generally, pigs should not be moved to clean quarters or exposed to uninfected pigs for approximately one week after treatment.
  2. Pigs exposed to contaminated premises, soil or pasture may need retreatment if reinfection occurs.
  3. Louse eggs are unaffected by ivermectin and may require up to three weeks to hatch. Louse infestations developing from hatching eggs may require retreatment.
  4. Consult a veterinarian for aid in the diagnosis and control of internal and external parasites of swine.

Accepted Compatibilities

Ivermectin is compatible with the following drug/drug combinations. In cases where there are differences in withdrawal time for the compatible medicating ingredients, the longer withdrawal time is the one that must be used, and is the only one that is to appear on the label of the finished feed.
