The objective of this study was to evaluate environmental aspects that affect the infestation of the Caracu cattle breed by the cattle tick Boophilus microplus (Canestrini, 1887) and to estimate genetic parameters for the level of this infestation. Countings of the parasite were done on female cattle from two herds, during all four seasons of the year, in two consecutive years (from September 1998 through July 2000). The number of ticks (NC) on one side of the animal was counted, […]
