Comparative efficacy of Keetguard, amitraz and Deltamethrin in naturally infected Rhipicephalus spp. ticks in cows

M Kumar, SN Yadav, S De, MN Singh, J Roy, AK Nath and MP Baishya

A total of 32 clinical cases of cows infested with Rhipicephalus spp. ticks were divided into four groups with eight animals in each group. Group A were given weekly tape water bath for 3 consecutive weeks whereas group B, group C and group D were applied externally keetguard liquid, deltamethrin 12.5% and amitraz 12.5% at their recommended dose at weekly intervals for 3 consecutive weeks. Amitraz or keetguard treated groups showed complete knock down of all ticks from cows after 2nd weeks of application while deltamethrin treated groups revealed complete knock down of ticks after 3rd weeks of application. Treatment with keetguard showed 66.02% and 100% efficacy while amitraz treatment showed 77.08% and 100% efficacy against ticks on the seventh day and fourteenth day, respectively compared to day 0 values. However, deltamethrin treated cows revealed 54.08%, 96.60% and 100% efficacy against ticks on day 7, day 14 and day 21, respectively compared to day 0 values. Amitraz and keetguard showed comparable in-vivo efficacy against tick infestation in cows.
