An epidemiological study was carried out from October 2016 to April 2017 in order to establish the epidemiology of Haemonchus contortus infections in small ruminants of Tiruchirappalli district. A total of 700 faecal samples were collected from randomly selected sheep and goats, and has been examined using standard coprological techniques. An examination of the conjunctiva’s colour has been associated with parasitic diagnosis to assess the degree of anaemia in animals. The study disclosed an endemic evolution of haemonchosis in the study region. The overall prevalence was of 335 (47.85%) with a mean eggs per gram of faeces (EPG) of 310 per infested animal. No significant influence could be attributed to host’s species or age. The season has been a major significant variation factor, wherein the prevalence of haemonchosis was higher in wet seasons (67.00%) than in dry (33.50 %). Elsewhere, a strong correlation was found between the conjunctiva colour and the worm burden but with a reverse influence of the season. In rainy seasons, degrees of anaemia have been low even though the intensity of infection was high. Inversely, moderate EPG levels induced detectable anaemia during dry seasons.
