Ivomec Injection is the original injectable ivermectin for cattle at 10 mg/mL, dosed at 1 mL per 50 kg. An injection puts a measured dose into every animal regardless of coat condition or weather, which a pour-on cannot promise — the trade-off is that cattle have to be crushed and handled one at a time.
Supplied in a 1L pack. For a backline option see Ivomec Pour-On, and for liver fluke cover in the same injection see Ivomec Plus.
Key points
- Ivermectin 10 mg/mL — 1 mL per 50 kg bodyweight
- Schedule 6
- Meat WHP 28 days, ESI 42 days
- Not for lactating dairy cows — do not use within 28 days of calving or during lactation where milk is for human consumption
Controls
Gastrointestinal roundworms (Ostertagia, Haemonchus, Trichostrongylus, Cooperia, Oesophagostomum, Nematodirus, Bunostomum, Strongyloides, Toxocara, Trichuris); lungworm; eyeworm; sucking lice; Sarcoptes scabiei var bovis and aids control of Chorioptes bovis; cattle tick including organophosphate-, synthetic pyrethroid- and amidine-resistant strains. It does not control the cattle biting louse (Bovicola bovis).
Safety
Macrocyclic lactone actives (ivermectin, abamectin, moxidectin, eprinomectin) are toxic to dogs, and severely so in herding breeds such as Collies, Border Collies, Australian Shepherds and Kelpies. Keep dogs away from treated animals until the product has dried, store the container out of reach, and dispose of empty packs and used syringes where a dog cannot get at them. Withholding periods and export slaughter intervals apply — read the label before treating any animal destined for sale, and rotate chemical groups between seasons rather than relying on one active, because resistance is the main reason a treatment stops working.
