Effects of different epidemiological factors such as season, age, sex and manage mental practices of animals on the prevalence of gastrointestinal (GI) helminth infection were studied in buffaloes of Red Laterite Zone (RLZ) West Bengal. Monthly 120 faecal samples of buffaloes of RLZ were screened by standard parasitological techniques from April, 2016 to March, 2017. The prevalence of naturally occurring GI helminthoses was 54.17% in buffaloes. Paramphistome (34.37%) was found to be the predominant parasite followed by Strongyle (21.50%) and Toxocara (10.07%). Highest prevalence was recorded in monsoon (60.42%) followed by winter (54.17%) and summer (47.92%). Young buffaloes (63.93%) were more susceptible to GI helminth infection than the adult buffaloes (49.32%). The prevalence of GI helminths was higher in female animal (60.67%) than the male (49.41%). Semi-intensive system (59.17%) of rearing showed higher infection than the intensive method (41.36%). The results of the present study should be exploited to formulate control program against GI helminths infection in buffaloes of West Bengal.
