Superdog, we don't have those things here for pretty much the reason that Francismilker stated in his second paragraph. Better that you spend the dollars on a drench that is going to be effective for your cattle in your area.
Mtman, I agree with your post wholeheartedly. For years it's been dinned into us that we should be drenching on a regular basis irrespective of whether the stock needed it or not. Now we've got ourselves to the point where drench resistance has become a very real thing and we're very close to having ruined one of our greatest tools. I drench on a needs-to basis and there are cows on this farm that haven't been drenched for several years. Some of the older milking cows need it twice a year, mainly for Liver Fluke which is a killer in my area, and I guess with increasing age the ability to deal with producing milk, being pregnant, and keeping her own body weight up means that dealing with a worm burden of any type becomes more difficult.
Cheers,
Ronnie
