Yak rearing is considered to be a primary means of livelihood for nomadic people. Heavy infestation by parasites often causes significant loss to them. So far, a few studies have been conducted to determine the prevalence and effect of ecto-parasites in Yak. Thus, a study was conducted by taking 118 yak samples randomly categorised into different age groups during which ecto-parasites were found.
Of 118 samples, 26 (29%) yaks were infested by ticks. The study revealed that mostly ticks are found on the yak’s brisket, fore flank, on the neck region and anterior and posterior thighs. Moreover, the study observed that most of the ticks were found in young, old age and weaker animals probably because they are less resistant or more susceptible to ticks. This could be also because of age difference and different environmental factors while grazing in different ecological zoon. Those tick infested yaks showed clinical symptoms such as weakness, emaciation, restless with pale eyes that lead to anaemia for animals.
