Gastrointestinal parasites (GIP) have a profound impact on livestock farming because they can significantly overshadow the productivity of animals. Retrospective study of diseases is an evidence-based and cost-effective study to understand the prevalence of a disease in a particular population and to outline effective treatment and prevention measures. This retrospective survey was carried out to estimate the prevalence of GIP and to identify risk factors of GIP infections in livestock (cattle, sheep and, goats). Fecal samples of 1733 livestock were examined using the simple sedimentation and floatation technique in the present survey from January 2018 to December 2018 at Haluaghat Upazila, the hilly part of Mymensingh. The overall prevalence of GIP in ruminant livestock was 49.7% (861/1733). GIP were more prevalent in goat (51.1%, 384/751) than cattle (48.9%, 425/870) and sheep (46.4%, 52/112). Twelve different GIP were recorded, where Eimeria (13.8%), Fasciola (12.1%), Paramphistomum (10.0%), Toxocara (4.2%), and Strongyloides (3.7%) were predominant. Amid sexes, infection was significantly higher in female (60.4%, 508/841) than male (39.6%, 353/892) counterparts. Age-wise prevalence showed the highest infection in young animals of goat (68.0%), sheep (60.0%), and cattle (53.2%). GIP infection was significantly higher in the rainy season collectively (64.1%, 452/705). GIP is highly prevalent in livestock of the study area therefore; proper attention must be given to outplay the causal association and risk factors between host and parasites.
