[QUOTE="Lucky_P, post: 1664930, member: 12607"] No prob, KT. Sat in on a few parasitology webinars this week. When the macrocyclic lactone dewormers (ivermectin types) came on the market, they had 99+% efficacy against Ostertagia(brown stomach worm)... today, that efficacy has dropped to about 6%... virtually no longer effective on many premises. Those pour-ons were approved/licensed back in the day when effectiveness was high... but no longer. Add to that, differences in absorption between animals and the greater issue of 'misapplication' - improper dosing, improper application (needs to be applied along topline from withers to tailhead - not just squirted at/on the animal - pour-on on the ground or sides of the chute doesn't do anything ) to animal with dry clean unmatted haircoat. Use of pour-ons for fly control has played a big role in pushing us rapidly down the road to irreversible anthelminthic resistance to all members of this class of dewormers. [/QUOTE]
