Double-barrelled attack puts worms on back foot

摘要

Sheep producers will now be able to tackle worms and anthelmintic resistance with "double barrels" thanks to the introduction of the UK's first dual-action wormer. Startect from Pfizer not only contains two active ingredients from two different wormergroups for the first time, but also includes an entirely new purple class of wormer. Derquantel is from the new anthelmintic class called spiroin-doles (purple class) and abamectin is a potent ML wormer (or clear wormer) which has never previously beenused on UK sheep.
