  • Effects of implant Suprelorin on cytological changes of vaginal epithelial
           cells in female dogs (4.7 mg deslorelin)

    • Authors: T. V. Holumbiyovska, V. Y. Stefanyk, T. P. Basarab
      Pages: 3 - 10
      Abstract: Diagnosis of the estrous cycle in female dogs is important in veterinary medicine. The estrous cycle is divided into the following stages: proestrus, estrus, diestrus, metestrus, and anestrus, which due to the action of hormones, replace one after another. This feature of the estrous cycle leads to some difficulties with reproduction. It is hard to obtain newborns because of prolonged anestrus. Vaginal cytology is a simple and available diagnostic method of the estrous cycle. It is based on the analysis of vaginal mucosa epithelial cells changes. This method is used to determine the time of mating and diagnose pathological conditions in the reproductive system of female dogs. There are various drugs in veterinary medicine for the correction of the estrous cycle in female dogs. We used implant Suprelorin® to estrus induction. There were described methods of estrus stimulation using a subcutaneous implant Suprelorin (4.7 mg, deslorelin) and changes in vaginal epithelial cells using the vaginal cytology method. The study was performed on twelve (n = 12) adult female dogs in the anestrus stage. Implants were injected subcutaneously in the groin area and removed at the beginning of the estrus.

      Abstract: The scientific article presents the results of investigating the spinal cord`s morphology of a domestic bull (Bos Taurus). Data on the histo- and cytostructure of the spinal cord are given according to the results of histological, neurohistological, and morphometric studies. For their implementation, the selected material (spinal cord n = 8) was subjected to fixation in 10–12 % neutral formalin solution, followed by pouring into paraffin. Histological sections were made from paraffin blocks on a sliding microtome MS-2 with a thickness of not more than ten μm. Staining of sections with hematoxylin and eosin, according to Van Gieson's methods, as well as neuro-histological methods of impregnation of nerve tissue with silver nitrate according to the Bilshovskym-Gross method, was used for the morphometric studies, investigating the morphology of the cell, conducting and obtaining the review histological preparations. The histostructure of the spinal cord, the localization of neurons in the gray matter, and morphometric studies of structural elements were examined on histological specimens by light microscopy. The entire experimental part of the research was conducted following the requirements of the international principles of the "European Convention for the Protection of Vertebrate Animals for Experimental and Other Scientific Purposes" (Strasbourg, 1986). The spinal cord, medulla spinalis, an organ of the central nervous system of vertebrates, is located in the spinal canal. The spinal cord is protected externally by soft, arachnoid, and hard meninges. The space between the membranes and the spinal canal is filled with cerebrospinal fluid. It is well known that groups of multipolar nerve cells with the same functional value form the nuclei of the gray matter of the spinal cord. According to the results of our histological studies, a pronounced differentiation of nerve cells, which have different shapes and sizes. Among them are large, medium, and small nerve cells. The shape of nerve cells is different, which, in turn, depends on their location in certain areas of the gray matter of the spinal cord and the size of the cell. In general, there are multifaceted, stellate, spindle-shaped, elongated, rounded, and oval neurons. Small nerve cells have an oval or round, less often – irregularly rounded shape, medium – round, oval, spindle-shaped. Large nerve cells are dominated by a multifaceted shape with distinct processes. The nuclei of large nerve cells, in most cases, have a rounded shape, less often – oval, mostly in the center of the cells, seldom – eccentrically. According to the results of morphological studies, it is noted that the neurons of the gray matter of the spinal cord have different shapes and sizes. Consequently, in the gray matter, small cells are the highest quantity (47.91 ± 0.32 %) of the total number of nerve cells. The second place is occupied by average neurons (33.70 ± 0.46 %). The large cells are detected in the smallest amount (18.37 ± 0.50 %).

  • Antimicrobial peptide MPX alleviates the lethal attack of Escherichia coli
           in mice

    • Authors: Xueqin Zhao
      Pages: 16 - 21
      Abstract: Escherichia coli is an important zoonotic pathogen causing intestinal diseases. In recent years, due to the unreasonable use of antibiotics, the drug resistance of bacteria has been increasing, and the proportion of multi-drug resistant strains has also been rising, which directly threatens the health of animals and humans. The antimicrobial peptide MPX was isolated from wasp venom and had better antibacterial activity against Gram-positive and Gram-negative bacteria. Studies have found that MPX had better bactericidal activity against E. coli in vitro. However, whether MPX also has better bactericidal activity in mice is still unknown. This study found that E. coli infected mice lost appetite, diarrhea, and grouping together, while MPX treatment significantly alleviated these symptoms. The autopsy results found that the intestinal congestion, bleeding, thinning of the intestinal wall, yellow viscous fluid in the intestinal cavity, congestion of the lungs, necrosis in the liver, congestion, and bleeding of the spleen, and MPX treatment effectively relieved the above symptoms. The qRT-PCR results found that MPX could increase the mRNA expression of the antibacterial protein TFF3 in the jejunum and colon and reduce the expression of the antibacterial protein Remlβ and REG3γ in the jejunum and colon. H&E staining results further found that MPX could alleviate the pathological damage of mouse intestines and organs caused by E. coli infection. The above results show that MPX has good bactericidal activity against E. coli infection in mice, providing an essential reference for screening drugs for the clinical treatment of E. coli infection.

  • The influence of global warming on the productivity and quality of
           cow's milk

    • Authors: O. O. Borshch
      Pages: 22 - 27
      Abstract: The objective of this research was to analyze the dynamics of productivity, quality composition and energy value of cow's milk obtained during three periods (3 years each) in central Ukraine by various technological housing variants. Over the last 20 years, there has been a global trend towards of increasing in the average annual temperature, which is especially felt in winter and affects to the cattle body, their productivity and the energy value of milk. To more effectively overcome the consequences of changing weather conditions, various continentally-achieved spatial composition and types of facility for livestock housing are used, the impact of which is not sufficiently studied. We analyzed the main weather indicators for the last decade in the central part of the Forest-Steppe of Ukraine (Kyiv region). The time period from 2011 to 2019 was conditionally divided into three periods (3 years each): I moderate, whose main weather indicators corresponded to the average long-term (30 years) values inherent in this natural and climatic zone; II (with a deviation of +0.6 °C from normal values) and III (with a deviation of +0.9 °C from normal values). During cubicle housing in low cost facilities was observed that productivity increased by 0.19 and 0.97 kg in II and III periods compared to I. During cubicle housing in facilities with insulation systems productivity gradually increased by 0.47 kg during II periods and by 0.92 kg during III periods. The most uniform productivity indicators were observed by housing on a deep litter among low cost facilities. Thus, productivity increased by 0.24 kg during II periods period, and in III period it increased by 0.47 kg compared to the I period. The dynamics of average daily productivity have a slightly more uniform by housing in capital facilities compared to low cost facilities. During tie housing productivity increased by 0.18 kg in II periods, and in III periods it increased by 0.32 kg. Productivity increased by 0.19 and 0.43 kg in reconstructed capital facilities during II and III periods.

      Abstract: Studies on the effectiveness of the inclusion of sodium humate in the diet of young cattle were conducted on four groups of animals. Installed improvement in the consumption of hay by the bulls of the experimental groups by 12.5–20 % compared with the control young was found, as a result of which they consumed more feed units by 1.5, 2.3, and 3.5 %, exchange energy – by 2.4, 3.9 and 5.1 %, digestible protein – by 1.2, 2.1 and 3.7 %. As a result of the inclusion of sodium humate in the diet as part of the KR-2 compound feed, the amount of hemoglobin in the blood of animals of the II experimental group increased by 5.8 %, in III – by 6.8, in IV – by 7.8 % compared to control analogs. With the growth of calves in the blood, the bactericidal activity of blood serum increased by 1.3, 1.9, and 2.5 %, lysozyme activity increased by 0.1 %, 0.2, 0.3 %, which indicates an increase in natural resistance in animals whose diets were injected with the studied peat and sapropel preparation. The use of sodium humate in the feed of bulls in the composition of compound feed KR-2 has a positive effect on the feed consumption, physiological condition, resistance of animals, which provides an increase in the average daily increase in live weight by 3.2–9.4 % while reducing the cost of its production by 2.9–8.5 percent.

      Abstract: Abiotic (water quality) and biotic (Phyto-, zooplankton and benthos) factors in the Kantivka fattening pond the Khmelnitskrybhosp Private Joint-Stock Company were studied during the vegetation seasons in 2020. The aquaculture objects in the pond are cyprinid fish species (carp, grass carp, silver carp, pike). The ecological conditions of the pond were evaluated as good enough for the fish fattening purpose. The critical water quality parameters were following traditional values accepted for fish farming in Ukraine. The taxonomic composition of plankton and benthos was represented by widespread and Ubiquiti species mainly. The 124 species and intraspecies taxa of microalgae and the 34 species of zooplankton were identified in the Kantivka fattening pond. The mean abundance and biomass for the phytoplankton were 183.8 million cells/dm3 and 35.61 mg/dm3, respectively; for zooplankton, those were as 336600 ind/m3 and 14.83 g/m3, and for zoobenthos, those values were as 309.6 ind/m2, and biomass as 5.84 g/m2. Such parameters of natural forage base correspond to the optimal values for natural fish food according to fish farming standards in Ukraine. In the late summer, the free-living copepod stages and mature adult females of the parasitic copepod crustacean Ergasilus sieboldi Nordmann were registered in plankton. This copepod causes the invasion of fish diseases like infection and destruction of gill arches, which leads to a severe disturbance in fish respiration, emaciation, delaying in growth, and the potential death of commercial fish even. The development of natural fish food in the Kantivka fattening pond is shown an intensive level of biomass and abundance of phytoplankton, zooplankton, and zoobenthos. It is considered sufficient to meet the natural nutritional needs (in combination with artificial feeding) for older age groups of the cultivated cyprinid fish species.

      Abstract: Despite the increased interest in the quality and safety of cooked sausages, the situation in the field of food is becoming more complicated and more threatening every year. As a result of research, it should be noted that the consumer market of the Rivne region is saturated with products of good quality, which are made mainly by mini-shops or private enterprises. When inspecting sausages, it was found that the city's stores in 2020 sold more than 50 tons of high-quality products in a wide range. These include boiled sausages, hot dogs and sausages, semi-smoked, boiled-smoked, raw-smoked, beef, pork and chicken delicacies, pâtés, loaves of bread, ham, and skewers. Experimental studies have shown that their name and manufacturer influence the evaluation of cooked sausages. The highest score was given to the sausage “Molochna” and “Teliacha z vershkamy”, which has become an authentic brand. Buyers of our country should prefer it. According to organoleptic and physical studies, further Examination of five samples of cooked sausages from different manufacturers showed that the samples meet the requirements of DSTU 4436: 2005. Microbiological tests revealed that the samples of cooked sausages met the requirements of regulatory indicators. Sausage “Likarska”, Yalovycha “Liuks” and “Z vershkamy” on two physical indicators: the content of mass fraction of moisture and mass fraction of salt, did not meet the requirements of DSTU 4436: 2005, this product is a counterfeit.

  • Antagonistic effect of Bacillus subtilis isolated and identified from
           different honey species against Klebsiella pneumoniae bee pathogens

    • Authors: A. R. Lakhman, O. Ye. Galatiuk, T. A. Romanishina, V. L. Behas
      Pages: 48 - 53
      Abstract: The search for alternative methods for treating and preventing bee dysbacteriosis is a priority for beekeeping as a branch of veterinary medicine. Lime honey, buckwheat honey, flower honey, forest honey, and acacia honey were tested to evaluate their antagonistic effect against a test culture of enterobacteria of bees of Klebsiella pneumoniae species. The study was conducted in several stages: 1. Determine the activity of honey microflora against a pure culture of enterobacteria of bees of Klebsiella pneumoniae bee pathogens; 2. The identification and isolation of Bacillus subtilis – bacteria-antagonists against Klebsiella pneumoniae bee pathogens; 3. Determine the antagonistic effect of pure culture of Bacillus subtilis against a pure culture of enterobacteria of Klebsiella pneumoniae bee pathogens. The antagonistic action of honey microorganisms and the determination of the most effective honey species were established by the diffusion method in agar wells. Staining of typical colonies from different types of honey revealed bacillary colonies of Gram-positive bacilli with endospores. Isolation of clean culture was conducted by a method of Gold. The cultural, tinctorial, and morphological signs of bacteria have been consistently determined in all investigated kinds of honey and coincided with characteristics of the Bacellaceae family. Specific belonging of bacteria-competitors was identified by biochemical typing. After determining their physiological properties in reactions and tests (activity of catalase, oxidase, urease, the ability to grow at different temperatures and to ferment carbohydrate substrate), the distinguished stamms of microorganisms from the investigated kinds of honey belong to the type of Bacillus subtilis. The repeated estimation of antagonistic action of pure cultures of Bacillus subtilis (isolated from each type of honey) against a pure culture of enterobacteria of bees of Klebsiella pneumoniae species confirmed their high activity. This type of microorganisms can represent the alternative component in probiotics at the therapy of dysbiosis of bees.

  • Amino acid composition of duck muscle tissue on using dietary supplements
           Activio

    • Authors: Ya. I. Kyryliv, I. S. Leshchyshyn
      Pages: 54 - 57
      Abstract: The optimal amount of protein is necessary for intensive growth. Protein malnutrition is one of the leading causes of poor growth and increased care of birds. However, excessive feeding of poultry with protein is impractical because the protein, in this case, is not fully used and harms the body, delaying its development. The lack and the excess of amino acids are harmful to a bird. Due to the imbalance of amino acids consumed with food, about 30 % of their amount is not used by the body for protein synthesis and is lost converted into energy. When normalizing the amino acid needs of poultry, it is necessary to consider the interaction of amino acids in the body with vitamins, micro-minerals, energy levels in feed. The article presents a study of the effect of the biologically active additive Activio, a selected combination of natural standardized active substances isolated from aromatic herbs and spices concentrated in one microencapsulated particle on the amino acid composition of Peking duck meat and cherry valley cross. It was found that the use of Activio supplement in the ducks feeding has a positive effect on the digestibility of amino acids.

  • Economic efficiency of different treatment schemes of cats microsporia

    • Authors: Ya. V. Kisera, Yu. V. Martyniv
      Pages: 58 - 61
      Abstract: The most common fungal skin disease in animals is microsporia; the principal causative agent is the fungus Microsporum canis. The disease is of fungal etiology and highly contagious. The pathogen can stay in the environment for a long time and pose a risk of human infection. Cats, especially those walking on the street, are a significant factor in transmitting the infection. Spores of Microsporum canis can persist on the surface of the cat's body for a long time and, under favorable conditions, can provoke clinical manifestations of the disease. Under these circumstances, they are intensively distributed in the environment. Therefore, choosing the optimal therapeutic approach to solving this problem is essential. Treatment of sick animals should be practical and aimed at preventing the spread of the pathogen and cost-effective and beneficial to both veterinary specialists and owners of sick cats, as the duration of treatment is on average 14–21 days in order to determine the cost-effectiveness of treatment of microsporia in cats with the antifungal agent “Micromar” and immunostimulant “Biogluk” in comparison with other schemes, the calculation of the cost-effectiveness ratio CER. This made it possible to obtain accurate and complete data, as it took into account the cost of treatment and the number of animals that recovered during the complex therapy. Sick animals were divided into three groups. Each sick animal received treatment for 21 days. The first group was treated with the systemic antifungal itraconazole and treated with a 1 % solution of clotrimazole. The second group was vaccinated twice with Vakderm antifungal vaccine and treated daily with a topical antifungal agent (1 % clotrimazole solution). The third group used the antifungal agent “Micromar” and immunostimulant “Biogluk”. To control the quality of therapy, culture was performed on the nutrient medium for dermatophytes from the affected areas of the animal's body. The calculation of cost-effectiveness indicators showed that the treatment of cats with microsporia is effective in all groups of studied animals, as recovery occurred in each patient. However, the costs of therapy are different. In particular, in the first group, the CER coefficient is – 48.00 hryvnias, in the second – 42.00 hryvnias, in the third – 13.00 hryvnias.

      Abstract: Agriculture, fisheries, and the food industry play a key role in ensuring the country's food security. The modern fishing industry in Ukraine is a highly industrial, capital-intensive, integrated production with high production costs, which is designed to ensure the socio-economic development of many coastal regions and provide the population with valuable protein products necessary for healthy eating. The total volume of extracted aquatic organisms in III and IV zones of aquaculture of Ukraine was studied; dynamics of catches of aquatic organisms by regions and fishery zones on the territory of Ukraine; the structure of fishing by regions in the inland waters of Ukraine is analyzed; the leading representatives of catches in inland waters of Ukraine by regions were identified. Considering the dynamics of catches of aquatic organisms in inland waters from 2005 to 2020, it was found that production decreased significantly in almost all Ukraine regions and some regions decreased to almost zero. Studies have shown that the total production of aquatic bioresources in 2005 amounted to 42.364 tons, in 2010 – 37.615 tons, in 2015 – 35.985 tons, in 2020 – 22.267 tons. In all periods, leaders among the production in inland waters are Odesa and Cherkasy regions. Comparing the data for 2005 and 2020, it can be seen that catches have almost halved. It is established that, according to the analysis, the main representatives of the caught ichthyofauna are: grass carp, carp, crucian, bream, silver carp, ram, pike perch, pike, perch, catfish. The structure of catches for the whole period remains almost unchanged. The largest catches (2019) are: carp – 1704 tons; silver carp – 675 tons Sumy region; crucian carp – 398.8 tons; ram (flat) – 364.5 tons Kyiv region. The main species found in the catches of other regions are – the Volyn region – carp (237 tons), Zhytomyr region – silver carp (300 t), Lviv region – carp (499 tons), Rivne region – carp (134 tons), Ternopil region – carp (342.4 tons), Khmelnytsky region – carp (279.2 tons), Chernihiv region. – carp (352.8 t). Pike, grass carp, and catfish were the least caught in the whole territory of Ukraine. It should be noted that several factors that affect fish stocks of inland waters, and consequently catches, most often consider the impact of environmental factors, destruction and inefficiency of spawning grounds, age and sex structure of populations, poaching, etc.

      Abstract: The study aimed to investigate the effect of the drug “Bendamine” on dogs' clinical and morphological parameters in heart failure. Two groups of dogs were formed for research: control (healthy) and experimental (sick). The 30-day experiment included ten dogs from the control group, ten dogs of the observed (unhealthy) spaniel breed, and 10–12 years old dogs. The treatment regimen for sick dogs: furosemide was administered orally on an empty stomach at 2 mg/kg every 12 hours; enalapril was administered orally at 0.5 mg/kg every 12 hours; Bendamine was administered orally on an empty stomach at 20 mg/kg every 24 hours. It is recommended to divide the dose into two doses. In the study of hematopoiesis, we found that erythrocytes in dogs with heart failure increased by 18.2 %, while hemoglobin levels decreased by 1.8 %. Before treatment, red blood cell counts were found to reduce the mean hemoglobin in the erythrocyte and the mean erythrocyte volume. In the experimental group of dogs treated with the “Bendamine”, normalization of morphological blood parameters was found. The number of erythrocytes was 5.8 ± 0.06 T/L, and the hemoglobin level was 143.5 ± 4.7 g/L. The use of the drug “Bendamine” contributed to the gradual restoration of the functional state of the hematopoietic system in dogs with heart failure. This is also indicated by the red blood cell index of the dogs after the course of treatment. The therapy application in the experimental group significantly reduced the frequency and severity of shortness of breath and increased endurance during exercise. There was also a decrease in the frequency and duration of cough attacks. After treatment, signs, and intensity of ascites decreased in dogs of the experimental group. It has been suggested that this is due to an increase in myocardial contractile function due to the positive ionotropic action of Bendamine. The owners also recorded an improvement in appetite in animals after 30 days of therapy. Even in the dogs of the experimental group, after treatment, physical activity and emotional reactions improved. They were less depressed and more inclined to communicate with the owners. Thus, the use of the cardiac drug “Bendamine” in dogs with heart failure positively affected the restoration of hematopoiesis and the normalization of morphological parameters of the blood.
