Queensland worms, flies and lice update - August 2016

Texas: Noel O’Dempsey, Sheep Veterinary Consultant (odempseyn@gmail.com)

A sheep producer was describing his worm control program to me the other day. Like all of us, sometimes he drenches just in case, especially when the sheep are already in the yards. He said that even if the sheep were not wormy they would benefit from being drenched. I suppose the discussion came down to – ‘What does a drench do?’ Basically, a drench only kills worms—no worms then no benefit from drenching.
