Abstract
The tick Rhipicephalus microplus causes huge damages to susceptible cattle that have high proportion of European genes. Conversely, zebu cattle are resistant to this parasite. The differences between tick-resistant and susceptible cattle have already been extensively studied, but some aspects of these differences remain undetermined. The objective of this project will be the study of the self-licking behavior of young Bos taurus and Bos indicus cattle artificially infested with 10,000 tick larvae. Other parameters related to morphology of the coat, skin and tongue and also those related to hepatic and renal function and well-being will be also evaluated in this artificial infestation. The quantification of acute phase proteins (Haptaglobulin, Serum amiloide A, Alfa-1-acid glycoprotein and transferrine) also the leptin and grelin hormones will be evaluated before and during the parasitic life cycle for monitoring the stress induced by tick infestation.
