Abstract

Helminth infections of the digestive tract in ducks (Anas platyrhynchos domestica) can cause significant economic losses, as they can lead to growth disorders, decreased egg production, and death in the case of severe infections. This study aimed to determine the prevalence and risk factors of digestive tract worms infecting ducks in Bali, Indonesia, through post-mortem examination. A total of 200 Balinese ducks (3�12 months) were examined post-mortem, obtained from six districts in the province of Bali using random sampling. The ducks were necropsied, and their digestive tracts and livers were sampled to identify the presence of the worms. The worms were collected and fixed in aceto-acetic-formalin-alcohol solution, stained with Carmine, and identified based on morphology. The relationship between the district origin, sex, and age of ducks and the infection of each helminth was analyzed using the chi-square test. The results showed that 83.5 (167/200) of ducks were infected with worms, consisting of 78.5 trematodes, 27 cestodes, and 15.5 nematodes. The identification of trematodes revealed 12 genera, including Hypoderaeum spp. (41), Protechinostoma spp. (16), Paramonostomum spp. (14), Cotylorus spp. (13.5), Apatemon spp. (11.5), Notocotylus spp. (10.5), Echinochasmus spp. (10), Pseudapatemon spp. (6), Echinostoma spp. (5), Methorchis spp. (5), Parorchis spp. (2.5), and Catatropis spp. (3). The cestodes found belonged to three genera, including Hymenolepis spp. (26), Fimbriaria spp. (10.5), and Cloacotaenia spp. (1). The only nematode identified was Tetrameres spp., with a prevalence of 15.5. The district of origin of the ducks was associated with trematode and cestode infections, whereas the age of the ducks was associated only with trematode infections. Based on these findings, this study documented the presence of 12 genera of trematodes, 3 cestodes and one nematode in ducks from Bali, Indonesia. © The Author(s) 2026 Open Access.
