Novartis Animal Health has launched a 0.5L pack of the anthelmintic Zolvix to make the product more readily available for quarantine dosing, and for the smaller sheep farmer.

Novartis says that because Zolvix is a broad spectrum anthelmintic that has the ability to kill all common sheep gastro-intestinal nematodes, including those resistant to existing treatments, it has a key role to play in quarantine treatment to keep parasite infection down to a minimum.

Simon Harris, Endoparasite Brand Manager at Novartis Animal Health, said: "As the first of the new generation of the Orange or 4-AD anthelmintic group, Zolvix has demonstrated effectiveness in killing worms, even those resistant to other products.

"Sheep farmers are being encouraged to use Zolvix as a quarantine treatment that can significantly reduce worm burdens on farm. I would stress that it is essential guidelines are followed in order to preserve Zolvix's ability to combat nematodes that have acquired resistance to other classes of wormers.

"This new pack size is aimed at farmers who are introducing new stock to their flocks, but will also be convenient for the smaller sheep farmer and smallholders who don't require such a large quantity of product."

Novartis says that because Zolvix is a short-acting anthelmintic, it does not encourage resistance to develop through a long duration of action. It has a high margin of safety so can be used to treat sheep and lambs including pregnant or lactating ewes and breeding rams. Its short meat withhold period of just seven days allows flexibility when marketing lambs.
