Prevalence of gastrointestinal parasites in three groups of domestic poultry managed under backyard system in the Savanna subregion, Department of Sucre, Colombia.

Objective: To identify the prevalence of gastrointestinal parasites that affect the backyard poultry system in the Savanna region, Department of Sucre, Colombia.

Materials And Methods: Fecal samples were collected from 860 native birds, both hens (), ducks (), and turkeys (), regardless of age and sex. Samples were processed using direct techniques with ZnSO and indirect methods such as modified Sloss. Data were presented as frequencies, and the nonparametric odds ratio test was used for two independent samples.

Results: A total of 77.3% (665/860) of the birds were infected with one or more species of gastrointestinal parasites. Among the nematodes, spp. (45.6%), (18.4%), (59.4%), (38.9%), spp. (25.2%), and spp. (12.2%) were recorded. The cestodes were (22.6%), (42.3%), spp. (58.3%), and spp. (54.7%), while only spp. (90%) was recorded as protozoa.

Conclusions: The study showed a high incidence of gastrointestinal parasite infestations, the most common species being spp., spp., spp., and .
