Selective control of Rhipicephalus microplus in a dairy cattle herd from different genetic groups
Alternatives for Rhipicephalus microplus control are needed in the light of its resistance to acaricides. One of the ways to decrease the use of acaricides in a herd is selective control (SC). In the present study, SC was evaluated in a dairy herd consisting of different genetic groups: Holstein, Je...

description | Alternatives for Rhipicephalus microplus control are needed in the light of its resistance to acaricides. One of the ways to decrease the use of acaricides in a herd is selective control (SC). In the present study, SC was evaluated in a dairy herd consisting of different genetic groups: Holstein, Jersey, crossbreed and Girolando. Ticks were counted in the right anterior third region on around 90 cows, totaling nine evaluations at intervals of 21 days. Commercial pour-on acaricide was applied only when the infestation was greater than or equal to eight ticks larger than 4 mm in the anterior third region. Tick counts were transformed into log(10) and analyzed using mixed models. There was significant difference among groups: Holstein had the highest averages of tick numbers, as expected, although 34.3% did not receive tick treatment. In the other groups, SC reduced the use of acaricides by 79.1% for crossbreed, 81.5% for Jersey and 94.9% for Girolando. The criterion used for applying the acaricide successfully kept the tick population under control. The great advantage of SC was savings to the system, without harming the animals, in addition to generate fewer residues in the animals and in the environment. |
