Topography and comparative morphology of kidneys in female and male broilers cross Ross-308 at the age of 60 days

Abstract

The study of the urinary organs of birds is of great practical importance when working in the field of poultry farming and makes it possible to improve the quality of the product obtained from poultry. Knowledge of the morphology of the urinary system in poultry is an important area for veterinary specialists. Kidney pathologies such as gout, nephritis, urolithiasis and neoplasia of various origins are a common problem in poultry farms. It is impossible to increase the productivity of poultry, as well as to carry out therapeutic and preventive measures without knowing its species and breed anatomical features. The work was performed at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. As the studied material, we used the corpses of Ross-308 cross broilers, aged 60 days in the amount of 10 pieces, 5 males and 5 females. The methods used for the study were fine anatomical dissection, morphometry and photographing. As a result of the study, we found that the length of the left kidney in males is 1.05 times greater than in females, and the length of the right kidney is 1.07 times. The width of the right kidney in males exceeds the females by 1.18 times, and the left – by 1.17 times. The girth of the right and left kidneys in males is 1.18 times greater than in females. We also found that in broilers of both sexes, the left kidney prevails over the right in size. On average, the left kidney is 1.02 times larger than the right one.
