Effect of Diet on Avian Leukosis
Abstract Boyd and Edwards (1966) showed that chickens fed diets deficient in essential fatty acids (EFA) or containing primarily saturated fat had high mortality when inoculated with Escherichia coli. In order to determine if other disease agents may cause the same effect, the diets described in the previous study were utilized and one-day-old chicks

Cell killing by avian leukosis viruses [PDF]
Infection of chicken cells with a cytopathic avian leukosis virus resulted in the detachment of killed cells from the culture dish. The detached, dead cells contained more unintegrated viral DNA than the attached cells. These results confirm the hypothesis that cell killing after infection with a cytopathic avian leukosis virus is associated with ...

Determination of the tumor virus b locus in turkish native chicken breeds [PDF]
Avian leukosis viruses (ALV) are retroviruses that can induce tumors in chicken. Typically, ALV is controlled through husbandry. However, genetic improvement and/or, selective breeding techniques, offer the unique possibility of true resistance.
