Abstract: Most of the dairy cattle in Nandi County are found in smallholder farms, where ticks and tick-borne diseases pose challenges to their productivity and survival. Dipping of the cattle in chemical acaricides, on weekly basis, is used to manage the ticks. Examination of the Countys tick control records for the period 2000 2012 revealed that 84.11 % of the registered cattle were dipped in communally-owned and managed plunge dips, while 15.89 % used privately-managed dips. Varying numbers of cattle were dipped annually (266, 178.330, 963), in either chlorfenvinphos, amitraz or synthetic pyrethroid acaricides. The dip-wash tests indicated that 56.36 % of the samples were at the standard dipping concentrations while 38.81 % were under-strength, and 4.83 % over-strength. Anaplasmosis and East Coast Fever were prevalent tick-borne diseases, at 47.74 % and 47.08 %, respectively. Babesiosis and heart water remained low. In conclusion, the plunge dips were prominent tick control facilities, but their use was not consistent with the recommended operating procedures, leading to persistence of tick-borne diseases.
