Until this last week I was under the impression that theileria would not kill baby calves but I just had an 11-day-old calf covered in what looked like seed ticks dead from theileria. Usually I wait till at least 2 weeks of age to put a pour on on baby calves to kill lice ticks and flies but with this revelation I'm using cydectin pour on baby calves to keep them alive.
