Asian Longhorned Tick Guide for Cattle Producers

Asian longhorned ticks are a growing concern for cattle producers in more than 25 states. The invasive species can rapidly multiply and infest cattle, transmitting Theileria orientalis Ikeda, a blood parasite that causes weight loss, decreased milk production, reduced fertility and even death. With only one vaccine currently available, cattle producers should work closely with their veterinarians to implement tick control measures and monitor herd health.
