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.
Materials 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 reo
virus as compared to the chicks from control group.
