Avoiding the reliance of drenching for worm control can provide more efficient worm control, and reduce the rate of development of resistance by worms to drenches.
Non-chemical worm control methods should be part of an integrated parasite management program that incorporates both chemical and non-chemical controls. On-farm management practices should be assessed for their economic benefit on a farm-by-farm basis and should also ensure animals do not suffer from poor health or welfare issues by not being drenched.
