ANATOMICAL AND HISTOLOGICAL CHARACTERISTICS OF ARBORACRES+ CROSS BROILER KIDNEYS WHEN EXPOSED TO A STRESS FACTOR
The purpose of the work is to study the state of the kidneys of broiler chickens under the influence of a stress factor. Research work carried out to study the topography, morphology, histology of poultry organs under the influence of a temperature stress factor was carried out in the laboratory of the Department of Anatomy and Physiology of the State Agrarian University of the Northern Trans-Urals. ArborAcres+ broilers were the subject of the study. The kidneys of both females and cockerels occupy an anatomically and topographically correct location. In females and cockerels, the left kidney is slightly smaller than the right one. The relative weight of two kidneys in females and males is on average 1% of body weight. Histologically, it was noted that the structural elements in females are significantly smaller in size than in males. Macrascopic changes were not revealed, however, when studying the histological picture of the kidneys, there was swelling of the cortex, granular dystrophy of the epithelium of the tubules, moderate plethora of blood vessels. All this points to the damaging effect of such a stress factor as high temperature, which negatively affects the function of the organ. This is due to the fact that the altered tubules do not adequately cope with their function, and with the defeat of an even larger number, the process may decompensate and the development of severe renal failure.
