Experiments were conducted to study sire family variation and variation among inbred lines in resistance to Marek's disease (MD). In three experiments chicks were challenged at 1 or 21 d of age with the BC-1 isolate of MD virus and the post-challenge test period was approximately 56 d. In a fourth experiment chickens were reared for 147 d at a field station where they were exposed to MD-infected birds. Sire families within each of the two strains studied, which had been selected for hen-housed egg production, were quite heterogeneous for resistance to MD and incidence ranged from 0 to 45.8%. The ranking of these sire families for incidence of MD did not correlate with ranking of sires for economically important traits measured in their sisters. MD among inbred lines in a 54-d experiment ranged from o to 88.9% and in a 147-d field experiment from 0 to 50%. In neither experiment was the inbreeding coefficient of inbred lines correlated with incidence of MD. |
