NEUROLYMPHOMATOSIS 25 



Necropsy Report on Birds in Mating 2 

 Bird No. Nerves, Plexuses, and Organs Involved 



Hens: 



VQ-1803 Coeliac, proventriculus, and ventriculus 



VQ-1908 Coeliac, right and left brachial 



Roosters: 



VQ-1847 Ciliary 



VQ-1870 Right and left sciatic 



VQ-2241 Ciliary 



Chickens from Mating 2, which developed Neurolymphomatosis 

 Chicken No. Age (Days) Sex Nerves and Plexuses Involved 



VQ-1908— C-13 204 Cockerel Right and left sciatic 



VQ-1908— C-14 117 Cockerel Right sciatic and left brachial 



Neurolymphomatosis did not occur in the 15 chickens produced by hen 

 VQ-1803 and rooster VQ-1847, or in one chicken resulting from the crossing of 

 hen VQ-1908 with rooster VQ-1870. Hen VQ-1908 and rooster VQ-2241, 

 however, gave 14 chickens two of which showed symptoms of the disease after 

 204 and 117 days, respectively. Hen VQ-1908 showed no infiltrations in the 

 ovaries, nor rooster VQ-2241 in the testes. The hatchability from Mating 2 

 was 69.76 percent and the percentage of neurolymphomatosis was 6.66.
