A total of 350 and 200 eleven-day-olc embryos (pooled breeds) of twelve hatch replicates were inoculated with pseudotype of Bryan high titre, RSV(RAV-49) of subgroup C viz CAM (chorioallantoic membrane) and YS (yolk sac) route, respectively. An increase in hatchability (about 16%) and decrease in the incidence of CAM(+) [71%] and LT(+) [47%] phenotypes was noticed when inoculation was done via YS route as compared to the inoculation via CAM routes. A delay in LT(+) mortality was also recorded in YS route of infection. Chi-square analysis within a route basis indicated highly significant contingency (P < 0.01) in association of CAM infection phenotypes and LT incidence phenotypes for CAM route of infection in contrast to the YS route of infection.
