Domesticated birds (515) consisting of 185 broiler (Gallus gallus domesticus), 130 layers (Gallus Sp), 75 free range local chicken (Gallus domesticus), 40 house pigeon (Columba livia), 70 ducks (Anas platyrhynchos) and 15 turkeys (Melleagris gallopavo) reared in valley districts of Manipur were investigated for intestinal protozoan and helminthic infections. Fresh faecal samples of these birds were examined microscopically by direct wet smear with 2.5 % potassium dichromate (K 2 Cr 2 O 7 ). Of these 412 (80 %) were found to be infected with different species of gastrointestinal parasites. The highest (90.8 %) prevalence of these parasitic infections was found in broiler followed by layer (78.5 %), duck (75.7 %), house pigeon (75 %), Turkey (66.7 %) and free range local chicken (65.3 %), etc. A total of 10 species of intestinal parasites were encountered. Among these, the protozoans Eimeria and Isospora were the most common (68.3 %) followed by mixed infection of protozoan and Helminths.
