At what age is Anaplasma most commonly seen in cows?

Anaplasma is a bacterial disease that can affect cattle, leading to various health issues including anemia due to the destruction of red blood cells. The age group most commonly affected by Anaplasmosis, particularly in cows, is usually between 2 to 4 years.

This demographic is particularly susceptible because they are often more exposed to vectors like ticks and may have developed enough of an immune response to be affected by the disease. Younger cattle, under 2 years, may not yet be exposed to the conditions that lead to infection, while older cows tend to have developed some level of immunity due to previous exposure. Additionally, the prevalence of the disease tends to peak within this 2 to 4-year age range, as these animals are typically more active and integrated into herds where transmission is likely to occur.

Understanding the timing of peak susceptibility can aid in effective management and vaccination strategies within cattle herds to minimize the impact of Anaplasma.
