Diagnostics of uric acid diathesis in birds of the parent herd of Ross-308 and Hubbard F15 crosses by pathoanatomic changes during post-slaughter veterinary and sanitary examination

Uric acid diathesis (gout) is a disease, connected with metabolic disorders, characterized by the formation and accumulation of uric acid in the blood, followed by its deposition in various organs and tissues. According to literary data, this disease in the industrial management of poultry farming can be recorded in 5-20% or more of poultry of different ages. The purpose of the work was to determine the degree of spread of uric acid diathesis in poultry of the parent herd of crosses Ross-308, Hubbard-F15 by pathomorphological changes in carcasses, internal organs during post-slaughter veterinary and sanitary examination and factors contributing to the development of this disease. The research work was carried out in the breeding farm of the LLC Bryansk Poultry Complex, a separate subdivision of the Tinyakovskaya poultry farm. The material for the work was chickens and roosters of the parent herd, slaughtered at the end of operation at the age of 448 days old for the Hubbard-F15 cross and 406 days for the Ross-308 cross. Besides, during the observation period, an autopsy of the fallen bird was carried out. Veterinary and sanitary examination of poultry slaughter products on the conveyor and autopsy of fallen poultry was carried out according to a generally accepted method. As a result of the work, it was found that the parent herd of the Ross-308 cross is more susceptible to the disease of uric acid diathesis than the Hubbard F15 cross. The characteristic pathological changes for uric acid diathesis during a veterinary and sanitary examination in a bird of cross Ross-308 were noted in 15% of the lot, the Hubbard-F15 cross - single, at the autopsy of a fallen bird - 20 and 15%, respectively. The following pathological changes were found on the slaughter conveyor: the kidneys were enlarged in size, impregnated with urates during the cut, urea salts were deposited on the liver, serous integuments of the intestines.
