A DOUBLE guarantee to kill anthelmintic-resistant worms and increase lamb growth rates has been introduced on the dual-active worming drench Startect.
Vet Dave Armstrong from manufacturer Zoetis says when used as a knockout drench for just one necessary mid-late summer lamb treatment, it eliminates any resistant worms that have survived previous treatments.
Compared with similar lambs on the same farm wormed with any other product, he adds that higher growth rates can also be assured.
“Elimination of resistant worms can be confirmed by faecal egg count 14 days after giving a Startect knockout drench. Farmers are also encouraged to monitor lamb growth rates over at least the following month,” said Mr Armstrong
If these checks find worm eggs present or zero growth rate advantage, the Zoetis network of field-based vets will investigate alongside the farm’s own vet, SQP or both, and help create a farm-specific worm control plan. The company will also pay associated lab fees and supply product free of charge for the following season.
