is there a generic cydectin on the market?

Even though they had the appropriate measurable amount of 'ivermectin' in them, efficacy - as measured by decreased worm egg counts was, in some cases, worse than for control calves that weren't even dewormed. Source(China, for instance) of the raw product may have more influence on efficacy than folks had thought...
I'll keep on buying the 'real thing', thank you. So what if you save a few cents per dose - if it doesn't kill the worms, you've wasted your money AND lost performance on the cattle.

Otherwise, how do you know the cows don't have worms - or that the ivermectin product removed them, if they had them?
Just wondering.
The study I referred to looked at the effect name-brand and generic ivermectin products had on reducing fecal egg counts, comparing before/after and non-dewormed control animals.
For the most part, I'm not convinced that deworming most cattle older than 1st-calf heifers is economically worthwhile.

This is what's perplexing me - they clearly work on my place (for flies) and, at least, for parasite control. How is that possible to have some a scientific study that is so easily contradicted? I suppose that's true of all science though.
