This epidemiological survey was conducted during April to September 2015. Results: The overall mean population and preferred site of tick attachment to infested animals, in Gambat, Sobhodero, and Kot Diji tehsils, were observed on different body parts. The primary body area of infestation by ticks (head, thorax, abdomen, udder, and tail) ranged from highest in tail and udder part compared to lowest in the abdomen, head, and thorax. In all study areas, the infestation was higher (p< 0.05) in tail and udder than other parts of the body. In all the study areas, the overall highest population was found in the month of July.
