- •
We assessed the seasonal changes in RBC values and infection rates of a tick-borne pathogen between grazing and indoor cattle.
- •
The Theileria orientalis infection rates for pastured cattle were increased after grazing.
- •
RBC values showed a dramatic decrease after grazing, leading to a remarkable increase of ticks in mountainous areas in the summer.
- •
These hematological changes may be associated with T. orientalis infection caused by tick-biting.
