Technical Abstract: Chickens from three commercial broiler breeders and two experimental lines were inoculated as embryos with strain ADOL-6803 of subgroup J avian leukosis virus (ALV-J). At various ages, chickens were tested for ALV-J-induced viremia, antibody and cloacal shedding; chickens were also monitored for ALV-J-induced tumors through 28 weeks of age. The incidence of viremic-tolerant chickens varied from 67% - 100%, whereas the incidence of tumors varied from 46% - 84%. Results suggest that chickens from commercial broiler breeders, regardless of breed were more susceptible to ALV-J infection and tumors than chickens from two experimental lines.
