The study was carried out from October 2013 to September 2014 in both organised and small sheep and goat farms of all the six taluks of Cuddalore district of Tamil Nadu, India. The objective of the present study is to determine the seasonal prevalence of gastrointestinal parasites in small ruminants. A total of 2160 faecal samples (90 from goat and 90 from sheep per month) were collected and subjected for analysis. Among the analysed samples 51.66% of sheep and 48.88% of goats were positive for endoparasites. The prevalence of gastrointestinal parasites was higher in sheep than in goats. The nematodes found in small ruminants were Haemonchus spp., Trichostrongylus spp., Oesophagostomum spp. and Bunostomum spp., and Haemonchus sp was found to be predominant in both sheep and goat. The results of season wise analysis indicates that the overall infection percentage was higher in rainy season, northeast monsoon (77.03% and 74.07%) followed by winter (58.88% and 55.55%) and in south east monsoon (48.61% and 27.77%) than in summer (25.55% and 22.96%) in sheep and goats respectively.
