A dip tank could provide excellent coverage, especially in areas that are difficult to reach. Our biggest concern is the stress of repeatedly putting cattle through that process every few weeks. Good coverage matters, but reducing unnecessary stress is also important when cattle may already be fighting disease.

Fogging every two to three weeks has worked well on Dr. Woodersonโs herd. He also applied Exalte on June 25 and had not fogged or treated the cows again at the time of this video. Approximately 30 days later, he was still seeing good fly control and no obvious signs of ticks.
For producers who cannot regularly fog cattle or use additional mineral strategies, Exalte may offer another option to discuss with your veterinarian.

Sulfur blocks may be a useful and affordable addition to a broader tick-control program. We do not consider them a single solution, and care should still be taken with overall sulfur intake, but they may help when used appropriately.

Garlic, sulfur, fogging and other preventative practices are being used by some producers as part of a layered approach. Many of these strategies do not have extensive research behind them, but we also have very few proven options for controlling Theileria and the Asian longhorned tick.

At this time, we have not seen enough evidence to recommend relying on it. There are currently no strong studies or proof showing that it effectively protects cattle from Theileria.
Theileria is a protozoan parasite, and vaccines against protozoa have historically been difficult to develop. We have seen this challenge with other diseases, including trichomoniasis in cattle and EPM in horses.

The first and most common concern is anemia. Cattle may also become thin, unthrifty, long-haired or appear to be struggling.
Prolonged anemia means the body is not receiving enough oxygen. Over time, that can contribute to kidney damage, liver damage and other organ problems. Even after the original problem is addressed, it takes time for the animal to rebuild red blood cells and recover.

Yes. We have seen cows experience significant decreases in milk production. In some herds, affected cows may produce 30 to 50 percent less milk.
That can lead to calves receiving less colostrum and nutrition, slower growth and weaker immune systems. Some calves may also be born already weak or anemic. We have seen estimates suggesting that as many as 10 percent of calves in an affected herd could be born with Theileria.

Yes. We are seeing higher abortion rates in herds affected by Theileria.
Remember that an โabortionโ does not always mean a dead calf. Premature calves, unusually small calves, calves with short hair or calves born weak may also be the result of a pregnancy ending before full term.

The most devastating situations we have seen are herds dealing with both Theileria and Anaplasmosis at the same time.
There is currently no vaccine or direct treatment for Theileria. However, there are preventative and treatment options for Anaplasmosis. Reducing the Anaplasmosis burden gives cattle one less major disease to fight.
CTC mineral and the Anaplasmosis vaccine may be important tools depending on your herd. The vaccine carried at our clinic requires two doses during the first year, followed by one annual booster when administered properly.

Cattle coming from areas farther north, south or west may be facing several new stressors at once, including Theileria exposure, ticks, flies and fescue.
Reducing stress wherever possible is important. Depending on the cattle and where they originated, producers may also need to discuss fescue-support products, fly control, mineral programs, Anaplasmosis prevention and tick control with their veterinarian.

We are still learning about the Asian longhorned tick and Theileria, and we likely have not yet seen the full long-term effect on cow fertility, milk production, replacement heifers, breeding bulls and future calf crops.
