The present study examined the prevalence and risk factors of anaemia in sheep in Shivamogga region from March 2023 to February 2024. The study involved screening of 200 sheep of which 166 (83.00 %) were anaemic based on matching the conjunctival mucus membrane with the CSWRI developed color chart. Anaemia was most common in sheep less than 6 months (87.25 %), and in female sheep (84.82 %). Monsoon season had highest prevalence of anaemia (90.16 %) followed by post-monsoon (86.11 %) season, winter (78.00 %) and least in summer (77.35 %). Based on aetiological agents the endo-parasitic infection was the most common cause (96.00%), followed by ecto-parasitic infestation (81.60%) and least in mixed parasitic infection cases (69.23 %). Risk factors of anaemia were found in animals reared by farmers with lack of awareness about deworming and acaricide, no education, not using dose based on body weight, lack of acaricide usage, sheep shed with mud floors, extensive type of rearing, feed which included only green fodder without concentrate and sheep drinking pond water all had higher rate of anaemia.
