Background: Gastrointestinal (GIT) parasites can reduce poultry productivity by negatively affecting the health of birds and altering specific blood values. Few published studies have addressed this issue in Libya, particularly in Al-Bayda and the surrounding areas. Aim: This study aimed to evaluate the presence and impact of GIT parasites on selected hematological parameters in selected free-range chickens (crossbreed chicken, Libyan chicken, and Fyomi) in Al-Bayda and the surrounding areas of Al-Bayda in Libya. Methods: A total of 50 fecal samples from adult chickens collected from local poultry breeders were examined for GIT parasites using the flotation technique. Blood parameters, including RBC, hemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and WBC, were also collected and analyzed using an automated hematology analyzer (Mindray). Statistical significance between complete blood count parasite positivity and reference parameters was determined using the mean standard deviation (mean +/- SD). Results: We detected GIT parasites in 100% of the samples. Among these, 48% had a single infection, 36% had two different parasites, and 16% had three parasites. The common parasites identified included Ascaridia spp. (24%), Heterakis spp. (14%), Capillaria spp. (18%), Eimeria spp. (64%), Trichostrongylus (12%), and Choanotaenia (20%). Several factors were significantly associated with the presence of GIT parasites, including farm location, years of operation, number of employees, proximity to water sources, fecal cleaning practices, and other animal presence. Conclusion: GIT parasites were found in the poultry of breeders in selected areas of Al-Bayda, Libya. These findings highlight the need for regular monitoring of GIT parasites and emphasize the need for consistent deworming or rotation of dewormers in the region.
