Make sure you have a strategy for parasite prevention and a plan B if parasite infections start to cause disease. Especially calves and young animals going out to pasture for the first time are at risk because they have not yet built up immunity to the parasites they encounter in the new environment.
This catalogue focuses on prevention in calves and young animals and provides an overview of the most common endoparasites. We have chosen to focus on lungworm, roundworm, grasshopper and liver fluke.
