I personally don't believe Panacur is 100% effective at killing off all EC spores as it is. What I do believe is it can help keep them at a manageable level so that the rabbit's natural immune system does not become over-run....allowing the rabbit to keep the infestation in check and hopefully therefor remain asymptomatic.
This is why I am unsure whether I feel all rabbit should be treated with a one off long course as youngsters (and possibly wreck natural immunity) or whether smaller annual courses work better as a control method.
I change my thoughts on this pretty much everyday and am exceptionally good at confusing myself :roll:
ETA- Just had a chuckle at the thread title....Confused? You will be now
