DETECTION OF AVIAN REOVIRUS ANTIBODIES IN DIFFERENT AGED OF LAYER BIRDS IN SMALL SCALE COMMERCIAL FARMS

Abstract

Avian reovirus (ARV) is associated with several disease syndromes in poultry and cause notable global economic losses in the poultry industry. Detection of avian reovirus antibodies from suspected field sera sample was based on serological test. The sera sample collected from ten age group (A1-A10) layer birds of different small scale layer farm in Dinajpur district of Bangladesh. Indirect ELISA (iELISA) was performed to detect the ARV specific antibody. In this study, the highest antibody titer was detected as 26120 and lowest as 288 by iELISA. The total 93.33 % sera samples were showed positive result. The highest mean titer was found in group A4 as 12648.88 which are 18 weeks aged birds. Therefore, to isolate and characterization of the reovirus further research is necessary.
