Circovirus diseases of pigs, manifested by the defeat of many body systems, are  widespread  and  cause  great  economic damage in industrial pig farms. The study of the  formation  of  specific  immunity  during vaccination of piglets against circovirus infection is of scientific and practical interest. The purpose of the research is to study the formation  of  specific  immunity  in  piglets during vaccination against circovirus infection. It was found that vaccination is accompanied by activation of the innate immunity system, which initiated the launch and formation  of  an  antigen-specific  adaptive  immune response. In animals 6 days after the introduction of the vaccine, compared with intact piglets, an increase in the content of pro-inflammatory  cytokines  IL-1ß,  TNF-α, IFN-α and IFN-γ and the anti-inflammatory mediator IL-4 was found, indicating a cellular  and  humoral  immune  response.  An  increase in the indices of inflammatory activity of mediators and the ratio of pro- and anti-inflammatory cytokines indicates an increase in the activity of T-helper I and the prevalence  of  cellular  immune  response.  Under the influence of technological stress caused by weaning from sows and transfer to rearing,  animals  14  days  after  vaccination showed a decrease in the level of IL-2, IFN-α and IFN-γ, inducing cellular immunity, as well as cytokine index, the ratio of pro- and anti-inflammatory  mediators,  which  indicates a shift in the direction of the immune response in the side of activation of the functioning  of  T-helper  II,  indicating  the  predominant formation of humoral immunity.","PeriodicalId":14419,"journal":{"name":"International Journal of Veterinary Medicine","volume":"511 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138982920","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 animals with clinically pronounced pathologies, blood samples were taken for biochemical studies. The following parameters were taken into account: ALT, AST, alkaline phosphatase, total protein, albumin, globulin, creatinine, urea, calcium, phosphorus. The nature of pathological changes in the distal parts of the limbs is influenced by the sharply continental climate of the Republic of Tatarstan, a sharp change in the ground for a short time, rocky or swampy terrain. The anatomical features of the structure of the hooves are determined by the environmental conditions and the features of the static and dynamic functions of the limbs under these conditions. Compared to cattle, the horny wall of the hooves is up to 8 mm thick, the angles of the toes are more obtuse, the shape of the hoof is rounded with a horseshoe-shaped protrusion. The main pathologies of the hooves in animals kept on soft ground are deformations of the hoof horn in the form of acute-angled and curved ones. On rocky ground there are a large number of cracks and clefts concentrated on the heel parts of the wall. The consequences of injuries are inflammatory processes of an acute and chronic nature: aseptic diffuse laminitis (namins) localized on the side walls of the pelvic limbs in the area of the heels and the toe part of the sole of the chest limbs.

According to experts, dyspepsia is a multifactorial disease, the positive outcome of treatment of which depends not only on the effective action of antibacterial therapy, but also on the timely prevention of the development of endotoxic shock, developing due to dehydration and overexpression of the nervous system.The studies were carried out on cattle calves up to 10 days of age of the Holstein breed. To study the therapeutic efficacy of the proposed treatment protocol, three groups of analogues were formed: two experimental and a control group (n=12). The calves of the first experimental group were prescribed: a decoction of oak bark inside, an antibiotic intramuscularly and intraperitoneal preparation \"Sterofundin isotonic\". In the second experimental group, pathogenetic therapy in the form of visceral novocaine blockade was carried out in addition to the first scheme. In the control group, they were prescribed: inside decoction of oak bark, an antibiotic intramuscularly, the drug \"Sterofundin isotonic\" intravenously. During the observation period, the general clinical condition was determined daily in the morning and evening. At the end of the experiment, the number of recovered calves, the severity of the disease, and the percentage of animal deaths were determined. On the first day and after 10 days, blood was taken from all animals to determine the dynamics of hematological changes.The use of a treatment regimen for toxic dyspepsia of calves with the inclusion of antibacterial, infusion therapy with simulta neous visceral novocaine blockade allowed to reduce the incidence by 2.7 times, increase therapeutic efficacy by 2.4 times compared with the control group. The duration of treatment with the use of the proposed treatment was reduced by 1.9 days, a significant increase in hemoglobin was noted in the blood of calves by 11.48% higher, lymphocytes by 1.68 times (p<0.05).
