SURVEY AND IDENTIFICATION OF GASTRO INTESTINAL PARASITES IN DOMESTIC CHICKEN (GALLUS DOMESTICUS L.) IN LOWLAND OF CAMBODIA

Abstract

In Cambodia, domestic chickens or backyard chickens are source of protein that are importance for people nowadays. Farmers raise the domestic chickens on their backyard. Chickens eat either insects or earthworm as intermediate host for parasites. Some of gastrointestinal parasites causes of zoonosis. The objective of this study was survey and identification gastrointestinal parasites in domestic chickens of lowland regions in Cambodia. 509 samples of gastrointestinal tract (GI) from carcasses were bought from markets and 409 fecal samples from caecum were examined by using the conventional methods. The GI samples were performed by gross examination and observed under stereo and light microscope. The fecal specimens were examined by simple sedimentation and simple floatation techniques. 483 from 509 (94.89%) specimens found the worm in GI tract. The most common parasites were nematode, cestode and trematode. They were positive 86.57, 84.47 and 6.09%, respectively. Echinostome, which is a zoonosis, was found 24 from 509 carcasses (4.71%) in Kandal, Prey Veng and Takeo provinces. The fecal examination was GI parasite positive 92.9% (380/409). The common parasites eggs were nematode, cestode, trematode and Eimeria oocysts,. They were positive 89.48, 13.2, 5.13% and , 60.88, respectively. This study showed the high prevalence of GI parasites in domestic chickens of lowland areas in Cambodia. Regarding from this information, it will be helpful for the veterinarians and researchers to design strategies for prevention and treatment the GI parasites in order to control some parasites that are causes of zoonosis
