šØ Attention Ringgold County Cattle Producers šØ
The Ringgold County Cattlemenās Association would like to make producers aware that the Asian longhorned tick (ALT) is making its way towards Iowa, carrying the bovine theileriosis (Theileria orientalis Ikeda) disease.
While this is concerning, awareness and early detection are the best tools we have to help protect our herds. This has been in the U.S. for 15-20 years as it started on the east coast and has worked its way west. Cattle will eventually create immunity to it, however this will only come with time.
š What is the Asian longhorned tick?
The Asian longhorned tick is an invasive tick species that can reproduce rapidly and feed on cattle, sheep, goats, wildlife, pets, and people. Large numbers of these ticks can cause irritation, blood loss, and reduced animal performance.
š¦ What is bovine theileriosis?
Bovine theileriosis is a disease caused by the parasite Theileria orientalis (Ikeda strain), which can be spread by the Asian longhorned tick. It presents similar to anaplasmosis but infected cattle may experience:
ā¢ Anemia
ā¢ Weakness or lethargy
ā¢ Weight loss
ā¢ Decreased milk production
ā¢ Jaundice (yellowing of the eyes or gums)
ā¢ In severe cases, death
Some infected cattle may show few or no signs while still carrying the parasite.
ā
What should producers do?
There are currently no FDA approved treatments for Theileria as it is a protozoan red blood cell infection. To mitigate against the issue you may:
ā¢ Regularly inspect cattle for ticks, especially around the ears, neck, brisket, udder, and tailhead.
ā¢ Work with your veterinarian if cattle appear anemic, weak, or unthrifty.
ā¢ Discuss tick control options that fit your operation.
ā¢ Continue practicing good biosecurity when introducing new animals.
ā¢ Report unusual tick infestations or suspected cases to your veterinarian.
This is a developing situation, and we encourage everyone to stay informed. The Ringgold County Cattlemenās Association will continue to share updates and educational information as it becomes available. Having a great relationship with your vet to ask them questions and to help mitigate against this in YOUR unique operation is a great resource to take advantage of!
Please help spread the word by sharing this post with fellow cattle producers. Working together, we can help protect the health of our local cattle industry.
