Effect of Diet on Avian Leukosis

Poultry Science, 1968
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]

Journal of Virology, 1981
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 ...

Co-infection with avian hepatitis E virus and avian leukosis virus subgroup J as the cause of an outbreak of hepatitis and liver hemorrhagic syndromes in a brown layer chicken flock in China

Poultry Science, 2020
Hens of a commercial Hy-line brown layer flock in China exhibited increased mortality and decreased egg production at 47 wk of age. From 47 to 57 wk, average weekly mortality increased from 0.11 to 3.0%, and egg production decreased from 10 to 30%, with ...

Determination of the tumor virus b locus in turkish native chicken breeds [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2017
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.
