Paralysis ticks can be deadly for calves and small breeds of cattle. See the preventative measures you can take to avoid toxic tick fever.

Tick fever is caused by the red blood cell (RBC) parasites Babesia bovis, Babesia bigemina and Anaplasma marginale.

It is transmitted between cattle by cattle ticks.

Tick fever is 3 times more common in Bos taurus cattle than in Bos indicus cattle, which have an inherent resistance to cattle tick.

Maternal antibodies from resistant dams protect calves to around 3 months of age and calves have an inherent resistance to around 9 months of age.
