This is a clinical examination of the general condition of the animal, organoleptic, physico-chemical, bacteriological research of the secretion of the mammary gland, radiological, ultrasound, laser, histological, cytological diagnostics, etc. Since all these methods in most cases are aimed at evaluating functional changes in the mammary gland and do not reflect the structural changes of the organ, so in the development of therapeutic and preventive measures to prevent the occurrence of pathological processes in the mammary gland in cows do not display information on pathomorphological changes in the tissues of mammary glands for mastitis of various forms. Histological diagnostics becomes an integral part of the clinical examination of animals in the activity of the doctor of veterinary medicine, because it allows taking into account the changes occurring in the tissues of the mammary gland, not only on the macroscopic, but also on the microscopic levels, which is especially important in differential diagnosis. Microscopic studies of biopsy revealed that normally the wall of the lacrimal alveolus consists of a single-layer cubic epithelium, a layer of myoepithelial (basintine) cells, a basement membrane and perialveolar connective tissue that contains numerous blood and lymphatic capillaries and nerve fibers. On the internal walls of the alveoli, there are secretory cells (lactoxytes) which, at different stages of their accumulation of secretion, or its separation into the lumen of the alveoli. The entire lumen of the alveoli is completely filled with a secret, which is rather intensely colored with eosin. In damaged alveoli, we detected the destruction of in situ lacticates, their excretion into the lumen with subsequent destruction there. In the destruction and removal of a small number of lacto-cysts in the lumen of the alveoli was a formed secret, in which an increased number of lactocytes and single neutrophils and lymphocytes were recorded. The given results indicate the pathohistological changes in cows’ mammary gland tissues under the chronic form of the mastitis. The method can be used as one of the important tests in the differential diagnosis of mastitis, which makes it possible to carry out in-depth study of the structure of the mammary gland of cows for various types of pathology using the method of biopsy of tissues from the affected area and the histological examination of the biopsy. Histology, as the most important scientific instrument of biology and medicine, is the only way to detect pathological changes in the tissues of the mammary gland. That is why histology of breast pathology serves as the most accurate diagnostic method in veterinary medicine and helps to choose the most effective way of treatment.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87383816","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}

The age of the fetus during pregnancy was established by anatomical parameters, whereas Pb and Cd levels in blood and substrates were measured by the method of atomic absorption spectrophotometry (GOST 30170896). The MPC (caruncle) and FPC (cotyledon) were analyzed separately. Their barrier function in relation to Pb and Cd was performed at its full extent in 4–5 months of pregnancy and coincided with the highest concentration in the fetal liver. Wharton’s jelly absorbed Cd in 3–4 months of gestation. With the approach of calving, Pb and Cd levels decreased in the amniotic fluid and increased in the allantoic fluid. Under the influence of fetoplacentat in MPC and FPC Cd accumulated better in AMF and ALF, whereas its levels were lower in the cortical mucus of the cervix. Pb deposited in equal concentrations in MPC of all the cows (0.46 ± 0.18 μg/kg in the contaminated environment and 0.47 ± 0.17 μg/kg in the relatively clean environment). In the relatively clean environment its levels in ALF were lower in 8 times (0.62 ± 0.16 μg/kg and 0.08 ± 0.04 μg/kg) and 26 times lower in AMF (0.52 ± 0.07 μg/kg and 0.02 ± 0.002 μg/kg), whereas Pb concentration in the cortical mucus of the cervix was 17 times lower (0.06 ± 0.03μg/kg) than that in the contaminated environment, (1.01 ± 0.28 μg/kg). Pb transited from MPC (0.46 ± 0.18 μg/kg) to FPC (0.51 ± 0.19 μg/kg), deposited in the internal environment of the uterus wherefrom it was absorbed by the cortical mucus of the cervix (1.01 ± 0.28 μg/kg).

The purpose of the work was to study the effectiveness of modern antihelminthic drugs for the spontaneous capillariasis geese. Experimental testing of antihelminthic preparations of domestic production was performed: piperazine 45% (DR – piperazine adipinat), 22% phenzole (DR – fenbendazole) and brovadazole plus (DR – piperazine adipinat, phenbendazole). The efficacy of the drugs was determined by the results of helminthic autopsy and coproscopicof the geese of the experimental and control groups. The main indicators of the action of drugs were extensiveness and intensive. It was established that according to the results of helminthocoproscopic investigations, the most effective drugs for capillariasis geese were phenzole 22% and brovadazole plus, their effectiveness at day 15 of the experiment was 100.0%. Efficiency (EE and IE) of piperazine 45% was slightly lower and at day 5 of treatment, according to the results of the coproscopy, was 40.0% and 65.0% respectively, for 10 days – 70.0% and 76.0%, for 15 days – 70% , 0 and 82.0%. At the same time, according to the results of helminthic autopsy geese in the process of their treatment, the effectiveness of the preparations of phenzole 22% and piperazine 45% were lower. EI of experimental geese for 15 days with the use of phenzole 22% was 40.0%, and II decreased from 21.20 ± 1.16 to 2.00 ± 1.00 ex./head. In the application of piperazine, 45% of the experimental poultry EI for 15 days reached 60.0%, II decreased from 22.40 ± 1.12 to 3.67 ± 0.58 ex./head. Extens- and intensefficiency of piperazine 45% was 40.0 and 86.0%, phenzole 22% – 60.0 and 92.0%, respectively. It was determined that the most effective preparation for geese capillariasis is brovadazole plus (EE, IE – 100.0%), which is confirmed by the results of coproscopic studies and helminthic autopsy.

This could be explained by the presence in milk of various hormones, particularly insulin-like growth factor (IGF). This hormone is a mediator between somatotropin and tissues. In response to the increase of the blood level of growth hormone, hepatocytes begin actively synthesize the IGF, which accelerates the rate of the metabolism, including those of onco-cells. The majority of studies relate to humane medicine, and data on the dependence of IGF milk levels on breed, period of lactation, diet, physiological, and clinical status of an animal are lacking. Taking this into consideration, the purpose of this study was to analyze the concentration of insulin-like factor in colostrum, milk of cows and blood plasma at various stages of lactation. Study was performed on cows of Ukrainian black-and-white dairy breed in their from second to fifth lactation with milk yield 5100–5700 kg per previous lactation. Concentration of IGF was detected in colostrum, milk and plasma of cows, using enzyme immunoassay. Obtained material gives evidence that the highest IGF level is present in colostrum. After that hormone concentration decreases up to 10–14 day of lactation. High level of IGF in colostrum might be associated with necessity to stimulate metabolism of calves in early postnatal period of ontogenesis. Immediately after calving plasma level of IGF decreases. The highest level was observed on 10–14th days of lactation. Taking into consideration physiological function of the given hormone, there is no univocal explanation of the decrease of its plasma level in cows at the beginning of lactation. This could be associated with energy deficit, physiological condition of animals or with developing of lactation dominant and levels of other hormones. Potential of further research lies in investigation of the dependence of the IGF level in the secretion of the mammary gland on productivity, breed, age and diet of animals.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72735698","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}

They are of the utmost importance for the structure and function of all cells, tissues and organs. Proteins reflect the state of the organism, as well as those changes that occur in it under the influence of internal and external factors. We studied the dynamics of changes in indicators in protein metabolism in cows depending on the season of the year and the location of a farm. The research was carried out in two farms of the Lviv region: the Danylo Halytskyj LLC, near the State Mining and Chemical Enterprise “Sirka”, and FE “Lelyk” of Zhovkva district, in spring, summer, autumn and winter periods of keeping. The object of research was the blood of 20 cows of Ukrainian Black-Spotted breed. According to the results of the research, a reduction in total protein, relative to the physiological norm of 0.45 g/l. in spring, and by 0.64 g/l in the summer, dysproteinemia, a high level of gamma globulin fraction (50.30%) in cows from the Danylo Halytskyj farm, located in the zone of influence of the State Chemical Medicine Plant “Sirka”. In animals FE Lelyk, located in the conventionally clean zone, this indicator was significantly higher, and was 76.14 g/l in spring, and 78.17 g/l in summer, and also in animals of this farm dysproteinemia was not observed. In the autumn, at the end of the summer grazing period of the keeping, the index of total protein tended to decrease in the animals of the Danylo Halytsky's Ltd., and in winter it was normalized and invested in the limits of the physiological norm. Albumin fraction of protein in this group of animals, throughout the search period, had a tendency to increase. In the cows of the FE “Lelyk”, the indices of protein metabolism were within the limits of the physiological norm in all periods of research, with the inherent fluctuations in the season of the year. The obtained results due to the content of total protein and protein fractions in the plasma of blood of cows kept in territories with different ecological status indicate that the effect of the activity of the State Chemical Medicine Plant “Sirka” is sufficiently strong on the organism of animals.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73699274","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 especially true today, when almost 69.5% of meat is produced in private home farms. It is mainly sold in the agro-industrial markets. The State Service of Ukraine for Food Safety should perform the conditions of modern European regulation and base its activities on the basis of risk assessment. One of the risks are parasitosis, as their negative effect affects the health of millions of people in the world. In this cjnnection the purpose of the study was to analyze the dynamics of the identification of invasive diseases at the stages of slaughter of animals and the sale of slaughter products. Research material was reporting on veterinary medicine (Form № 5-vet and Form № 6-vet) of a number of districts of Odessa region for 2014‒2017.

It helps to determine the optimal parameters for the implementation of the reproductive potential of the breeder boars. Biochemical methods of research can establish imbalance in metabolism, the nature and localization of cytolytic processes by the degree of enzymes activity in serum. However, in order to detect inflammatory or destructive changes in the connective tissue structures, in particular the musculoskeletal system, the most informative indexes will be biopolymers of the connective tissue – glycoproteins and proteoglycans. The results of a complex examination of clinically healthy breeder boars with different regime of their production use, which includes an extended set of biochemical tests with the determination of glycoprotein, chondroitin sulfate, total glycosaminoglycans and their fractions, are presented in this paper. It was found that the level of such parameters as the total protein and its fractions, urea, aspartate and alanine aminotransferase activity, and the MB fraction of creatine phosphokinase did not have any significant differences. For breeder boars that were used in reproductive events irregularly (group I), there was an indicative higher level of creatinine and glycosaminoglycans. In animals with regular use as the herd (group II), the level of creatinine and fractions of glycosaminoglycans (GAG) was lower, but there was an increasing in cholesterol, β-lipoproteins, and activity of total creatine phosphokinase. The probable difference in these indicators can be explained by the difference in the intensity of the energy metabolism processes in muscle tissue. Indeed, during long-term hard work of skeletal muscles, not only glycogen stores are used, but also the use of lipids is of great importance. In addition, the raising of cholesterol and β-lipoproteins may be due to their active involvement in the synthesis of steroid hormones. Increasing the activity of total creatine phosphokinase in blood serum of animals with the intensive use in technology probably is the evidence of severe physical activity and the development of destructive processes in muscle tissue (hyperenzymemia is detected in early stages of myopathy). The absence of the most inflammatory processes was evidenced by the unchanged level of serum glycoproteins, which are known as the acute phase tests. Differences in the parameters of the state of connective tissue were determined at the levels of general GAG, their I and III fractions (chondroitin-6-sulfate and heparan sulfate, respectively). In the first group of boars, there was a higher level of I fraction of GAG, that indicated a significant load on the joints' cartilages and the gradual development of destructive processes in them. About the III fraction of GAG, an increasing of the","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80352403","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}

For the purpose of treatment of blood parasitic transmissive diseases, domestic and foreign researchers tested a significant number of drugs of different chemical composition. In connection with the insufficient on the domestic market of drugs on the basis of imidokarb dipropionate for the treatment of blood-parasitic diseases in animals, the Scientific-Production-Technical Enterprise “Brovapharma” established and conducted the state registration of the drug “Imcar-120”, which blocks the synthesis of polyamine; it also has significantly less toxicity than dimeters of aceturates. It provides a broad spectrum of antiprotozoal effects on pathogens of pyroplasmiosis of the genus Babesia (Babesia bovis, B. ovis, B. bigemina, B. colchica, B. equi, B. divergens, B. canis, B. caballi, B. gibsonii i Francaiella colchica); Teilerian species (Theileria annulata, T. sergenti, T. mutans, T. orientalis, T. ovis, T. recondita, T. tarandirangiferis); Nuttallia equi and the genus of Anaplasma (Anaplasma marginale, A. ovis, Ehrlichia canis) with their mono- or mixed infestation. Pre-clinical research “Determination of toxicological properties of the drug Imcar-120” was carried out on the basis of vivarium of the Faculty of Veterinary Medicine of Sumy NAU. Study of parameters of acute toxicity of the study drug was performed on 50 clinically healthy white mice in males and females. Before the experiment, the individual weight of the body of animals selected for the experiment was 18–22 g, the age was 8–9 weeks. In the first stage, preliminary experimental studies were conducted to determine the variation of dose limits before the main stage of the studies. At the same time the drug was administered intragastrically in doses: 2500, 3500, 4500, 5500, 6500, 7500 mg/kg. Each dose was given to three animals. After the introduction of the drug for monitoring animals, the experiment was carried out 14 days, the first day – every hour. For the expanded stage of the experiment, four experimental groups (n = 8) of animal analogues were formed, in which the study drug was injected under the same conditions as in the previous stage of the experiment at a rate of 3800, 4300, 4800 and 5300 mg/kg of body weight.  In the course of studies to determine the parameters of acute toxicity of the drug Imkar-120 it was determined half-lettable dose of the drug. According to R. Kerber's method, DL50 was 4456.25 mg/kg, therefore according to the classification of GOST 12.1.007-76 the preparation Imkar-120 should be classified as hazard class III by injection into the stomach – substances are moderately dangerous.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86883330","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}
