While speaking to a client briefly today and thinking of the many other conversations I have had, I decided that a quick overview of Theileria in cattle is warranted.
Theileria orientalis is a tick-borne disease transmitted by the Asian longhorn tick pictured below. The disease appears to have entered this area 3-5 years ago. The organism enters the body and begins infection in the bloodstream, infecting white and red blood cells. Symptoms have been known to vary greatly. It can present similarly to Anaplasmosis, which we have dealt with for years. An adult animal with weakness, possibly unable to stand, and eventually death. But we have also found that it can cause a compromised immune system, which allows animals to be more susceptible to pneumonia, abscesses, and other diseases that usually would not be that severe. In these cases, it seems that the animals cannot recover from common illnesses. This also includes calves, whereas anaplasmosis only affects adults clinically.
Unfortunately, there is no approved treatment for Theileria in the United States, but it is essential to treat any other symptoms seen, such as antibiotics for pneumonia, abscesses, etc. Because the tick is the primary vector, it is crucial to be more vigilant in tick prevention. Also, consider not putting the herd in heavily wooded areas during peak tick season. As the tick is the primary vector, it can also be transmitted by needles when vaccinating and treating animals, so it is good practice to switch needles between animals. Please do not hesitate to reach out if you have any questions. (573) 477-3321

Remember in drought years we need to be vigilant in monitoring the nitrate levels in our forages. Drought causes the nitrogen to be elevated in the plant when considering how far it travels up into the plant and how much of it is in the plant. Some of the increased fertilizer applied to help grow more forage in the face of a drought can also increase levels. The most common types of forages that we see issues with are corn, Sudan, and Johnson grass but there are others to watch for as well. The nitrates can be in the grass, in the hay, or even in haylage or silage. The ensiling process does however decrease the amount of nitrates in the forage. Testing is readily available and can be done as a precaution. If you have any questions or concerns please don’t hesitate to contact us.

Update: After checking into it I found that the local feed stores have trouble getting the testing chemicals but if you call your local extension they usually have some availability or can get you in contact with someone that does. If not we can send a sample to the university.

The feed directive was put into place several years ago now by the FDA. This year in June (June 2023) they have decided that all medically important antibiotics will become prescription. This means that to buy medicated boluses, penicillin, tetracycline (LA200), etc you will have to have a prescription or buy it from your veterinarian. Just wanted to let everyone know to ensure that no one is caught off guard by the change. If you have any questions about this don’t hesitate to let us know.
