To evaluate the effect of vaccination with a Russian live vaccine (LTF 130) against ringworm in specialized beef production, half of the calves on 3 farms were vaccinated on arrival with 5 ml. A booster vaccination was given 2 weeks later. Statistically significant protection was achieved only on 1 of these farms. When the vaccine dose was increased to 2×10 ml on 2 farms, a statistically and biologically significant preventive effect was recorded at both.
