Abstract:

The genetic control of resistance to RSV (RAV-50) in chick embryos inoculated via the chorioallantoic membrane route was studied in three breeds of chickens. The relative susceptibility to subgroup D infection was 0.01, 0.02 and 0.003 in broilers, White Leghorns and Bantam×Australorp crosses, respectively. The distribution pattern of putative d^r gene frequencies were 0.80, 0.68 and 0.90, respectively, in the same three breeds. Liver tumours resulting from the virus infection were observed in a very few birds about 28 days after hatching.
