Article Synopsis
  • The study examined the susceptibility of taurine and zebuine cattle to the cattle tick Rhipicephalus microplus, focusing on tick population dynamics within the same herd over two experiments.
  • In the first experiment, researchers analyzed tick burdens in various age groups of cattle, noting that nursing calves reared in groups had higher tick burdens compared to those raised individually and that tick peaks occurred more frequently in weaning calves and lactating cows.
  • The second experiment involved infesting cattle of different ages with tick larvae to measure how many fully engorged females detachment occurred, with the results indicating age and previous tick exposure affected tick burden and treatment needs.

Data regarding parasitemia (blood smears), rectal temperature (RT), packed cell volume (PCV) and vaginal mucosa coloration (VMC) of Gyr x Holstein female calves between 3-7mo were accessed to evaluate different techniques for monitoring the bovine tick fever agents (TFA). The 1 experiment determined the correlation between the TFA parasitemia with RT and PCV. The 2, evaluated the associated risk of A.
