Approved claims

For growing swine (starters, growers and finishers) - Claim 1

Note:

IVOMEC 0.04% Premix is approved for claim #1 only.

Claim 1: 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 Drug:

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

Directions:

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

Warning:

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 uninfested 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.

Claim 2: For the treatment of infections and infestations caused by the following internal and external parasites in breeding swine:

Gastrointestinal roundworms: Ascaris suum (adults and fourth stage larvae), Ascarops strongylina (adults), Hyostrongylu rubidus (adults and fourth stage larvae), Oesophagostomum spp. (adults and fourth stage larvae) and Strongyloides ransomi (adults and somatic larvae).

When given in the feed during the last month of gestation ivermectin prevents transmission, via the colostrum or milk, of infective S. ransomi larvae from the sows to the piglets.

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

Lung worms: Metastrongylus spp. (adults)

Lice: Haematopinus suis

Mites: Sarcoptes scabiei var. suis

Level of Drug:

100 mcg/kg body weight daily in the complete feed for sows, gilts and boars.

Directions:

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

Note:

Feed labels will be required to state both the bodyweight of the swine being fed, as well as their daily feed intake.

Warning:

Treated breeding sows must not be slaughtered for use in food for at least fourteen (14) 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 uninfested pigs for approximately one week after treatment.
  2. Louse eggs are unaffected by ivermectin and may require up to three weeks to hatch. Louse infestations developing from hatching eggs may require retreatment.
