ABSTRACT
Background: The avian reoviruses have emerged to induce various manifestations in chickens. They are associated with disease conditions including malabsorption syndrome, tenosynovitis etc. Reoviruses are an important cause of suboptimum performance in broilers, resulting in poor growth performance. Poultry industry in India is facing a catastrophe due to such infections which go unnoticed in field due to masking of the symptoms by secondary infections and commonly observed nutritional disorders. Aim: To investigate the effect of reovirus infection on overall performance of broiler birds. Material and Methods: The broiler birds were challenged with homologous strains of malabsorption syndrome and tenosynovitis syndrome of reovirus. The growth performance was recorded. Results and conclusion: The growth performance and immune response to NDV did not differ in the birds challenged with tenosynovitis syndrome strain of reo virus as compared to un challenged birds. However, poor live body weight, feed intake, FCR, PE and BPEI and better serum NDV titres were found in chicks challenged with malabsorption syndrome strain of reovirus as compared to the chicks from control group.
