Anthelmintic resistance is an important consideration for every parasite strategy. It is important to monitor and treat animals selectively. That means only treat those animals who need it most. To slow or prevent antimicrobial resistance at least 30% of the animals must not be treated. More information on parasites and the 5 Star Worm Program can be found in the Handbook for the Control of Internal Parasites of Sheep and Goats developed by Canadian researchers and extension personnel.
