The objective of this study was investigation the prevalence of gastrointestinal helminthes (GIH) among sheep in Kalubia Governorate, Egypt. A total of 830 native breed of grazing sheep both sexes with age between 6 months to 3 years old were examined for the presence of gastrointestinal helminthes during the period from January 2019 to December 2019. 830 Fecal Samples from sheep were parasitologically examined. The current study revealed that a total prevalence was 71.44%, the highest seasonal prevalence was significantly (P<0.05) recorded in autumn (95.75%) followed by winter 67.98% while summer showed the lowest prevalence (58.81%). The total prevalence of single infection was (50%). The highest significant single prevalence (P<0.05) was recorded by Trichostrongylus spp. (41.7%), While the lowest prevalence was by Avitellina spp. (1.9%). The total prevalence of mixed infestation with different helminths species was 34.2%. Fecal culture examination of positive feces revealed that Trichostrongylus spp. and Chabertia ovina were the most and least prevalent larvae (24.2%, 10.8%; respectively). There was no significant effect of sex on the prevalence. Sheep of 6 months to one year old expressed a high prevalence (84.8%) , but sheep > 2 years old had a relatively low infection (52.2%). . In conclusion, it was noted that GIH are endemic at high levels among sheep in the study area and need great effort to control these parasites.
