Always used closamectin twice a year on the calves, 8-10weeks after turnout and a month before weaning/selling in the autumn without a problem. Vet advised save money and use ordinary wormer(non fluke) for the spring worm, didnt work in my opinion so got them in and wormed again but with closamectin which cured the husky/flukey coughing. Never have much problem with pneumonia tbh
The pneumonia reference was about the only reason I could think of for fluke causing a cough, but it would be a very extreme case where cattle would be pretty much cruelty cases, so it as good as certainly is not fluke causing the cough.
Which wormer didn't work?
