Prevalence of Tumours and Antibodies against Leukosis and Sarcoma Viruses from Subgroups A and B in Layers

Popis výsledku v původním jazyce

Viruses belonging to the leukosis/sarcoma group represent a frequent cause of neoplasm inpoultry. The aim of this study was to assess the frequency of tumours and the prevalence ofantibodies against leukosis/sarcoma viruses from subgroups A and B in laying hens of domesticfowl (Gallus gallus f. domestica), both in parents and production flocks from the Czech Republic.A total of 91 flocks of laying hens from three different slaughterhouses were examined for thepresence of tumours. The occurrence of neoplastic lesions was found to be low. Although tumoursoccurred in 82 flocks (90.1%), their incidence in 62 (68.1%) flocks was below 0.5%, and it onlyexceeded one percent in 3 flocks (3.3%). 9 flocks (9.9%) had no tumours. In order to determine thespectrum of the tumours, 14 randomly collected samples were histologically examined. Thetumours found in hens at the end of the laying period showed varied histogenesis (five cases ofpancreatic adenocarcinoma, three cases of adenocarcinoma of the o
