The present study was undertaken to study the etiopathology of dead-in-shell embryos of Vanaraja bird egg procured from the bird being maintained at AICRP on Poultry Breeding, in the Institute. Total 1173 egg were incubated, out of which 101 (35.94%) were found with dead-in-shell embryos and 180 (64.05%) were found as infertile. Various abnormalities detected in the dead-in-shell embryos were malposition (29), malformation (10), dehydrated (3), adhesion (2), pathological condition (23) and undiagnosed (34). Out of 23 dead-in-shell embryos having pathological condition, 10 dead-in-shell embryos were sent for cultural examination from which 7 embryos showed septicemia. The organisms isolated from such embryos were Streptococcus spp., Staphylococcus spp. and Escherichia coli.
