The world's poultry population is increasing due to high consumer demand for poultry products. Due to the increasing growth of Galliformes breeding, this study aimed to investigate gastrointestinal parasites in the feces of some species of Galliformes. In this study, ۱۰۰ distinct fecal samples were collected from seven different Galliformes species, including rural chickens, peacocks, partridges, pheasants, turkeys, quails, and guinea fowls. Sampling of each bird was done separately. These birds were kept in cages. To identify gastrointestinal parasites, the samples were evaluated using the Clayton-Lane method, modified Ziehl-Neelsen, and Trichrome staining methods. Out of ۱۰۰ birds sampled, ۵۳% of birds were positive for gastrointestinal parasites. ۳۰% of birds were infected with Eimeria spp., ۱۸% of birds were infected with nematodes, and ۵% of birds were infected with Giardia spp.. The highest rate of parasitic infestation in Galliformes was related to protozoan infections and the highest rate of protozoan infection was related to Eimeria (۳۰%). Complex infestation was not detected. Considering that most parasitic infections have been detected in apparently healthy birds, it is recommended to observe hygiene and to regularly disinfect cages and reduce the density of birds in the nests. Due to the zoonotic potential of Giardia and due to the contamination of some birds with this parasite, this issue should be considered by public health officials, bird sellers' markets, owners, and breeders of these birds.
