Controlling parasites in sheep and goats
The development of dewormer resistance to nearly all three available anthelmintic classes is common in sheep and goats. Resistance has risen due to anthelmintics being used often, rotated too frequently, underdosed or using the cattle labelled dose. Sheep and goats metabolize the dewormer quicker than cattle, so their dosage is higher than cattle. Resistance makes control … [Read more...]
Managing parasite resistance; ‘set it and forget it’ no more
Ron Popeil popularized the 'set it and forget it' phrase in TV infomercials. The phrase could have been used to describe parasite control methods from past decades.

Change in cattle deworming practices may reverse resistance
Parasitologists saw dewormer resistance in cattle coming before most producers did. But, overuse of benzimadazoles, macrocyclic lactones and levamisoles in all their forms has increased reports of nematode resistance.
