With an ever increasing demand for animal protein, sheep rearing has gained momentum in the recent years. However, occurrence of tick borne haemoprotozoan diseases has a major impact on small ruminant production in tropical and subtropical countries. Hence, the present study was undertaken to determine the prevalence of haemoprotozoan parasites in sheep by PCR technique in three different agro-climatic zones of Tamil Nadu and to identify the tick species involved in the transmission of haemoprotozoan parasites such as Theileria Iestoquardi, Theileria ovis, Babesia ovis and Anaplasma ovis in sheep.enVeterinary ScienceThesis
