Cattle are at risk of infection when moved to areas where infected ticks are present. Infected animals can also spread infection to ticks when transported to new areas. In turn, this can spread disease to uninfected animals.
Tick control is important during risk period. This is commonly mid-August to mid-March, but as long as the mean air temperature is above 7˚C ticks will be active to some degree. Tick control is also important during periods of stress, for example calving and peak milk production.
- New arrivals and returning stock should ideally be quarantined for at least 7 days to check and treat ticks.
- Ensure all stock being transported to new areas are healthy and free from ticks.
- Observe cattle regularly during the risk period.
- Apply tick control products during the risk period. Franklin vets recommends Flumethrin and Python for cows.
- Treat other animals (hosts) on the farm for ticks
Prevention is not possible in areas where ticks are present. For people moving stock into areas with ticks, we would strongly advice that you carry out blood tests to determine if the animals being moved have been exposed to the parasite. If they have been exposed then there should be relatively little risk of them developing clinical disease, however if they haven’t come across the parasite before then they will be at a high risk of breaking down with clinical Theileriosis.
Avoid exposing naïve animals to infected ticks 6-8 weeks prior to calving /peak milk production.
Consult a Franklin Vets veterinarian for advice on tick control and Theileria on your farm.
