“…Важливе діагностичне значення має аналіз гістологічних і цитологічних змін внутрішніх органів трупа тварини, які являють собою відображення біохімічних і біофізичних процесів, що відбуваються після смерті, особливо в ранній постмортальний період, коли макроскопічні морфологічні зміни виражені ще не достатньо чітко (Jankowski & Piesniak, 2007;Zhukov & Lenskaya, 2010;Humphreys et al, 2013;Muzhikyan et al, 2014;Koptyaeva et al, 2018).…”

The cytomorphological changes of a cat’s cadaver’s parenchymal organs in the early postmortem period in the aspect of forensic veterinary examination are established in the work. The aim of the work is to clarify the processes of necrobiosis at the cellular level under aerobic environment in the first day after the death of the animal as a cytomorphological criterion in terms of forensic veterinary examination in deciding the age of death in the early postmortem period. It is proved that the most dynamic cytomorphological changes are found in the spleen and pancreas tissue; cytoarchitectonics of liver, lung and heart tissue changes less intensively. Intense cytomorphological changes in kidney tissue and brain were not observed. It was found that parenchymal organs samples cytological research after the first day of the postmortem period to determine the cells histological topography is impossible. It was found that the cytoarchitectonics dynamics of kidney and brain tissue is uninformative to solve the problems of forensic veterinary examination, but the necrobiosis of liver, lung and heart cells is moderately informative. High informativeness of cytomorphological picture change in spleen and pancreas tissue has been established, as the intensity of cytomorphological changes dynamics and their informativeness to solve the question of the age of death are directly correlated. It is recommended to use the cytological rapid method as an additional in the practice of forensic veterinary examination to address the issue of animal death age in terms of its non-obviousness before the appearance of late cadaveric phenomena.

Yorkshire pigs occupy one of the first places in livestock farms in different parts of the world. This is due to the fact that breeding boars of this breed are widely used by farmers and owners not only of large livestock complexes, but also by private farms for crossing with other breeds of adapted pigs to increase the meat indicators of offspring. Pigs of this breed are very sensitive to sudden changes in ambient temperature, often suffer from overheating or hypothermia, which can affect the health of internal organs and body systems and can lead to diseases of the urinary system in general and in particular the bladder. The purpose of our study is to study the features of the histological structure of the bladder wall in Yorkshire piglets in the age aspect. Cadaver material for the study was delivered to the Department of Animal Anatomy of the Federal State Budgetary Educational Institution of the Russian Academy of Sciences from the Idavang Agro pig breeding complex in Nurma village, Tosnensky district of the Leningrad Region. The study was conducted in three age groups, according to the periodization of pig life: the first stage of development – newborn piglets (1-4 days of the postnatal period); the second stage of development – the first dairy (5-21 days of the postnatal period); the third stage of development – the second dairy (22-45 days of the postnatal period). From the first stage of development, newborn one-day-old piglets were used; from the second stage – animals 10-14 days; from the third – piglets 28-30 days of the postnatal period of ontogenesis. The average body weight of piglets of group 1 is 550 g.; Group 2 is 1800 g.; Group 3 is 3000 g. In total, five piglets were inherited in each age group. The age was determined by the bonus cards and from the words of the chief veterinarian of the farm. To achieve this task, a set of traditional morphological research methods was used: fine anatomical dissection, histological, photographing and morphometry. Histological examination revealed that in Yorkshire piglets, the bladder wall has a typical histological structure and consists of mucous, muscular, and serous membranes. Morphometric indicators of histological structures of the bladder wall were determined and it was concluded that these values of thickness and diameter in males slightly exceed those in females.
