Coproscopy a Premordial Diagnostic Tool in Avian Parasitology

Abstract

Parasitic diseases are a problem that affects all poultry farms, whether large commercial or small backyard farms, where economic losses can be significant. In this study, a survey on intestinal parasites of chickens was carried out in the Souk Ahras region over a period of 6 months. The faeces of a total of 90 chickens collected from different farm types were examined by flotation to detect gastrointestinal parasites. The results obtained from these chickens showed that all the examined faeces were 100 % infected. The qualitative analysis showed a flocculation of helminths and protozoa’s oocytes across the taken chicken samples at different farms with different infection percentage. Broiler chicken reported infected with Ascaridia (50%); Heterakis (35%) and Eimeria (15%). The laying hen infected with Ascaridia, Heterakis and coccidial oocysts which represented by 33.33%, 33.33% and 33.34%, respectively. However, for the local chiken, Ascaridia: (40%) Heterakis (35%), Eimeria (15%), Syngamus (5%) and Capillaria (5%) were recorded. The high infection rate recorded in the study area suggested that an intensive poultry management system and regular chicken control should be held.
