WHY CHOOSE FIRSTMECTIN?

  • Contains abamectin in combination with praziquantel

    Abamectin is a potent, short acting member of the macrocyclic lactone (ML) family of drenches. Praziquantel is the only chemical that controls both segments and heads of tapeworm. It makes sense to remove tapeworms to reduce the overall worm burden of your lambs, giving them the best opportunity to achieve peak performance.

  • Broad spectrum parasite control

    FIRSTMECTIN is highly effective against abamectin sensitive gastrointestinal roundworms, lungworm, nasal bot and itch mite. It also provides control of tapeworms (heads and segments).

  • Ideal for lambs

    For a young lamb, life is a risky business. They’re vulnerable to cold, predators and worms. As soon as lambs start to eat pasture, they are developing a worm burden. Unlike older sheep, lambs haven’t built up their immunity against worms. Worm infections lead to reduced wool production and lower bodyweights in sheep of any age; a high worm burden will have a far bigger impact on young sheep.

  • Unselenised

    Excess selenium can cause toxicity issues in sheep, particularly if they are suffering liver damage from eating particular weeds. Where sheep are receiving sufficient amounts of selenium in their diet, it may be better to use an unselenised drench. If selenium supplementation via a drench is required, FIRSTMECTIN® SE is recommended.
