A comparative cross-sectional study on prevalence of naturally occurring gastrointestinal (g.i.) helminth infection was conducted for five years between the sheep of New Alluvial Zone (NAZ) and Red Laterite Zone (RLZ) of West Bengal, India. Faecal samples of 160 sheep were collected and examined by the standard coprological techniques at monthly interval from each of the agro-climatic zones. The overall prevalence of gastrointestinal helminth was 68.60% and 68.90% in sheep of NAZ and RLZ, respectively. Strongyle group of nematodes and Paramphistomes were more prevalent (P>0.05) in RLZ compared to NAZ. In monsoon the overall prevalence was higher in sheep of RLZ (82%) compared to NAZ (76.3%) whereas in summer the prevalence was significantly (P<0.05) higher in NAZ (61.5%) compared to RLZ (55.85%). The intensity of g.i. nematodes was higher in NAZ (EPG – 584.5) than the RLZ (EPG – 557.58) of West Bengal. Haemonchus contortus was recorded as the predominant parasites of both RLZ (64.8%) and NAZ (66.4%). The present study showed no significant (P<0.05) difference in prevalence of helminthic infection except in few occasions between the NAZ and RLZ of West Bengal. Therefore a common worm control programme can be adopted for the sheep of NAZ and RLZ, West Bengal, India.
