Gastro-intestinal Parasites of Domestic Ducks (Anas platyrhynchos) in Ibadan Southwestern Nigeria

摘要

A six month study (January to July, 2008) was carried out to determine the prevalence of gastro-intestinal parasites of domestic ducks {Anasplatyrhynchos) in Ibadan and environs. A total of 175 faecal samples were collected from ducks in six differentlocations and examined using formol-ether concentration method and modified Ziehl Neelsen staining technique, sodium chloride floatation and zinc sulphate sedimentation methods. Out of the 175 faecal samples examined 167 (95.4%) were positive for Gastro-intestinal parasites. A total of five different helminths and three different protozoan parasites were isolated from the faecal samples and identified. Among the helminths identified, Ascaridia galli 82 (46.8%) was the most frequently observed followedby Heterakis gallinarum 41 (23.4%), Capillaria sp. 38 (21.7%), Echinuris uncinata 20 (11.4%) and Syngamus trachea 13 (7.4%). For intestinal protozoa. Eimeria spv 60 (34.3%) was the most frequently encountered followed by Tyzzeria sp. 29 (16.6%) and Cryptosporidium sp. 27 (15.4%). Mixed infections with two or more parasites were common. A total of 75 (42.9%) had single infection, 38 (21.7%) double infection and 54 (30.8%) triple infection. We recommend intensive system of management for rearing ducks aswell as adequate Veterinary care for the ducks and strict hygiene for the owners and/or attendants.
