Further development of this sub-sector is of great importance for the agro-industrial complex of Russia. Since 2021, support for reindeer husbandry has been allocated in a separate direction of subsidies, including for the purchase of breeding breeding stock. Deer eco-farms located near cities have the opportunity to become part of the tourism industry. In addition, animals are a source of valuable products-dietary meat, high-quality leather raw materials, various types of medicines. However, to date, morphological features of deer representatives have been studied extremely insufficiently. This article presents the anatomical features of the flexors of the hip joint in the subspecies of the red deer – spotted deer. In particular, the points of fixation of the large lumbar, lateral and medial heads of the iliac muscle, tailor's and scallop muscles have been clarified. Topical bone landmarks on the pelvic (nameless) and femoral bones that are absent in the available literature have been identified: \"medial crest of the iliac wing\", \"roughness of the short tendon of the tailor's muscle\" on the iliac bone; \"roughness of the scallop muscle\" on the femur. The purpose of this study is to establish anatomical and topographic features of flexor muscles and adductors of the hip joint in the noble spotted deer, to determine the points of their fixation and to assess the functional significance of the studied structures.The research was carried out at the Moscow State Academy of Veterinary Medicine and Biotechnology – MBA named after K.I. Scriabin. The object of the study was a mature noble spotted deer (n=5), selected in the hunting farm of the Moscow region. The methods of fine macro- and microanatomic preparation according to Vorobyov were used, followed by functional analysis of the studied structures and skeletotopic projection of the points of attachment of parts of the muscle. The revealed anatomical features of the studied muscles are the reference in assessing the structural and functional state of the musculoskeletal system of the hip joint in the noble spotted deer.","PeriodicalId":14419,"journal":{"name":"International Journal of Veterinary Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83077997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":14419,"journal":{"name":"International Journal of Veterinary Medicine","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84836327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In individuals of the same species and breed, quite high discrepancies can sometimes occur in the topography of the coronary arteries of the heart. When studying the coronary bed of the heart of animals, we recorded a case of the presence of a right-handed type of blood supply in a two-month-old Blackand- White calf in the absence of a left coronary artery. In this regard, we set ourselves the goal of studying the features of the vascularization of the right half of the heart in a two-month-old Black-and-White calf with a right-sided type of blood supply.To achieve this goal, the heart of the corpse of a two-month-old Black-and-White calf, obtained from a private farm in the Leningrad Region, was studied. The study was conducted at the Department of Animal Anatomy, St. Petersburg State University of Veterinary Medicine. To study the vascularization of the heart of the studied animal, classical and modern anatomical techniques were carried out, such as fine anatomical preparation, photography, and the manufacture of corrosion preparations using latex.According to the results of the study, it was found that in the absence of the left coronary artery in the studied two-month-old calf of the Black-and-White breed, the right coronary artery completely and completely compensates for its absence. The presence of the right interventricular artery was established, which has such branches as the artery of the right septomarginal trabecula and atrioventricular branches that supply blood to the tricuspid valve area and the right septomarginal trabeculae of the heart. It was determined that the vessels that vascularize the structures of the right atrium and right ventricle in their topography in the studied individual are inferior in the number of S-shaped bends and sharp corners in comparison with the arteries of the left half of the heart, which can reduce the risk of developing coronary pathologies in the right half of the heart. It was established that the subsinus artery differs from the generally accepted classical topography and plunges into the thickness of the myocardium of the right ventricle and interventricular septum, and practically does not pass as part of the subsinus sulcus.","PeriodicalId":14419,"journal":{"name":"International Journal of Veterinary Medicine","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89507277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory assessment of the hepatobiliary system has several goals, including: determining the presence of hepatobiliary pathology, determining the presence of liver disease, including primary or secondary hepatitis, determining the definitive type of liver disease, and monitoring response to therapy or disease progression. We have comprehensively analyzed existing studies in the field of using various methods for diagnosing pathologies of the hepatobiliary system, identifying the most promising approaches from the point of view of veterinary hepatology for their further possible introduction into industry practice. The search and processing of scientific publications was carried out according to the recommendations of H. Snyder [10] for writing review articles. An assessment is given to the positive and negative sides of each technique.Based on the analyzed literature, it can be concluded that, despite the knowledge of the issues of hepatology and the diagnosis of liver diseases, there are gaps and weaknesses in any diagnostic model. Thus, one potential diagnostic model that is promising but little studied is the use of clearance tests. Functional tests allow not only to diagnose and differentiate hepatopathologies, but also to visualize their course and liver recovery.Also, unlike statistical tests, clearance tests allow you to evaluate the work of the liver in dynamics.","PeriodicalId":14419,"journal":{"name":"International Journal of Veterinary Medicine","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77129420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This situation also applies to indicators of the content of toxic elements, which include selenium and heavy metals such as zinc, copper, iron, capable of accumulation in the body and migration through food chains. In connection with the above, the purpose of the research was to monitor and analyze the content of heavy metals and selenium in compound feeds for productive animals and poultry sold on the territory of St. Petersburg and the Leningrad region as an indicator of toxicological safety.As part of the work, 40 samples of mixed feeds of domestic production were examined. The share of the studied compound feeds for pigs and piglets accounted for 50.0%, for broilers and cattle - 25.0% each. At the first stage, sample preparation and mineralization of samples were carried out in a muffle furnace. At the second stage, using the atomic absorption spectrometer Thermo Scientific Solaar S4, the amount of copper, zinc, iron, selenium in the mineralized sample was determined in accordance with the current regulatory documents. At the third stage, the results were analyzed in comparison with the temporary maximum permissible level according to MDU No. 123-4/281- 8-87 \"Temporary maximum permissible level (MDU) of the content of certain chemical elements and gossypol in animal feed and feed additives\".The detected concentrations of copper, iron and selenium in the studied samples met the requirements of the current regulatory documentation and did not exceed the established MDU.

The purpose of the conducted research is to assess the ecological and ichthyo - toxicological state of the Shlisselburg Bay of Ladoga lake, as one of the main fishery water areal and the only source of water supply of St. Petersburg (the source of the Neva River). Biological and chemical analytical studies of the water area of the Shlisselburg Bay in laboratory conditions were carried out in the summer-autumn period in 2022 in three water areas. A feature of the Shlisselburg Bay is the presence of a runoff flow, that initiates the removal of pollutants and the nature of bottom sediments, which makes the Bay less vulnerable to anthropogenic impact. Currently, the methods used to assess water quality for the fisheries perspective are biological – bioindication and biotesting, as well as the results of chemical analysis in comparison with the standards for the content of harmful substances in water, sediments, precipitation and fish. Preference is given to “express’ methods: biotesting and bioindication of fish research results. Analysis of materials from previous studies have given reason to consider a gradual decrease in anthropogenic load (exposure to pollutants) on fish, as generally recognized indicators of water quality, given from fisheries positions. The results of the research showed that the ecological and toxicological condition of the Shlisselburg Bay has now improved, but cannot be considered satisfactory.
