Cattle ticks (Rhipicephalus (Boophilus) microplus) are a serious economic problem for the Queensland dairy industry. The effect of tick infestation of dairy heifers is mainly lost production due to reduced growth. Other costs include the extra handling needed for treatments, acaricide costs and equipment and facilities for treatments. Cattle ticks also transmit organisms responsible for tick fever. Vaccination for tick fever is recommended for heifers between three and nine months of age.
As a dairy operator, you are obliged to follow animal welfare codes; in particular, freedom from parasitic diseases.
