[QUOTE="Lucky_P, post: 1838639, member: 12607"] Regardless of what folks want to think, it doesn't get hot or cold enough on this planet (other than in erupting volcanoes) to eliminate parasites. It's wishful thinking on folks' part. The macrocyclic lactones (ivermectin, doramectin, moxidectin) have been so widely used that Ostertagia ostertagii, the most important stomach worm for adult cattle, is almost extinct on most premises; at least east of the Rockies. I spent most of 40 years as a veterinary diagnostic pathologist, doing necropsies on cattle and 25 years of that time teaching parasitology to undergraduate students. I have not seen a mature cow that died from 'worms' since back in the early 1990s. Disclaimer: I've never lived, practiced, or worked in a location where liver flukes were present. Will cows have nematode parasites? Sure. Will they be present, in a healthy cow, at levels that they impact health? NO... Unless you are in an area where liver flukes are an issue... in that case, regular treatment with an effective trematocidal drug is indicated. [/QUOTE]
