Assessing the impact of Theileriosis on North Coast NSW cattle producers

Why are we doing this survey?

Bovine anaemia due to Theieleria orientalis continues to cause losses on cattle properties in the
North Coast region. The disease was initially seen approximately 12 years ago in adult cattle
introduced to the area from regions which do not have bush ticks, and therefore those cattle were
naïve. Since then we have seen losses in homebred calves at approximately 2-3 months of age. On
some properties these losses have been significant. In conducting this survey North Coast LLS is
hoping to be better able to quantify the cost of this disease to local producers, as well as identifying
possible risk factors.

Participation in this survey is voluntary and other than the time taken for you to complete the
survey, there is no cost to you.

If you would like to discuss the risk of Theileria to your stock in more detail with a District Veterinarian, you can contact North Coast Local Land Services on 1300 795 299.

We thank you for your time.
