On the migratory Black Sea lamprey and the nomenclature of the ludoga, Peipsi and ripus whitefishes (Agnatha: Petromyzontidae; Teleostei: Coregonidae)
Authors: Kottelat M. , Bogutskaya N.G. , Freyhof J.
Published: September 2021

The data on the extinct migratory Black Sea lamprey are reviewed. The records from the Prut (Danube drainage) apparently refer to Eudontomyzon mariae while those from the Dnieper and Don refer to a larger species, which is apparently extinct. No museum material is known to survive, and its identity cannot be resolved. Coregonus ludoga Polyakov, 1874 is an unnecessary replacement name for C. widegreni Malmgren, 1863. Coregonus lutokka nom. n. is proposed here as a new replacement name for C. ludoga Berg, 1916, the ludoga whitefish of lakes Ladoga and Onega. Coregonus maraenoides Polyakov, 1874 is the valid name of the Peipus whitefish. Coregonus ladogae Pravdin, Golubev & Belyaeva, 1938 is the valid name of the ripus of Lake Ladoga.
REDUCING THE ADVERSE EFFECTS OF THE OPERATION OF GAS FIRED MELTING FURNACES ON THE ENVIRONMENT
Authors: Straka Luboslav , Krenicky Tibor
Published: September 2021

Due to the growing production on a global scale, the use of fossil fuels is also increasing. Therefore, the control of pollutant emissions produced in the industrial sphere has become a global concern. In general, an imperfect combustion process has a negative impact on the overall efficiency and economy of plant operation, but at the same time increases the share of total emissions in the environment. We also encounter this problem when operating gas fired melting furnaces. Therefore, the paper aimed to describe the results of experimental measurements of the number of emissions produced during the operation of a gas fired melting furnace, which in practice is mainly used for melting alloys. Experimental measurements were oriented to find the most suitable variant of the operating mode of the gas fired melting furnace with regard to minimizing the total amount of emissions produced.
THE ENERGY OF SEA TIDES IN THE CONTEXT OF SOLVING CLIMATE PROBLEMS
Authors: Shirkova Elena , Shirkov Eduard
Published: September 2021

"The article presents an overview of the technical, economic, and environmental arguments in favour of wider use of the gigantic energy potential of sea tides to solve the most important climate problem today – the reduction of anthropogenic pollution of the Earth's atmosphere with carbon dioxide. The main idea of the considered solution is the replacement of carbon fuels for thermal power plants and transport with ""green"" hydrogen. The production of such hydrogen is carried out by electrolysis using the energy of carbon–free renewable sources. Tidal hydroelectric power plants are the cheapest, largest and most economically safe electricity supplier for the production of green hydrogen today. Until now, this direction of the energy sector has not become widespread due to the high capital intensity, as well as due to the geographic remoteness of the places where tidal energy is concentrated from large centres of electricity consumption. The explosive growth in global hydrogen demand in recent years alleviates the problem of very expensive transport and large losses in long distance transmission of electricity. Hydrogen can be transported without loss and relatively cheaply by pipelines and sea tankers over unlimited distances. The use of the energy of the highest tides and flow in the Pacific Ocean for the production of ""green"" hydrogen is proposed in the revived project of construction of the world's largest Penzhinsk Tidal Hydroelectric Power Plant (the Sea of Okhotsk’ north–east, Russia)."

Published: September 2021

Investigations were carried out to optimize the growth parameters of the symbiosis of cultures of the yeast Saccharomyces cerevisiae 121 and the fungus Geotrichum candidum 977 on whey waters formed from pea flour as a secondary product in the production of protein concentrates after precipitation of proteins at the isoelectric point. The whey remaining after protein precipitation is bioconverted at optimal parameters of crop growth (pH of the medium, amount of inoculum, temperature) with the formation of microbial plant concentrate (MPC) for feed purposes. Serum cultures assimilated stachyose, glucose, maltose, arabinose, and other pentoses. The mass fraction of protein in the concentrate was 57.90-61.68 % of DS. The composition of MPC obtained from biomass is balanced in essential amino acids with a speed of 107-226 %. The fatty acid composition is represented by 97 % fatty acids and 3 % - esters, aldehydes, ketones with the properties of fragrances, photo stabilizers, odor fixers, preservatives and other compounds. The ratio of the sum of saturated and unsaturated acids is 1:3, the content of cis-isomers is 91.1 %, trans-isomers are 5.1 %, omega-6 fatty acids are 19.73 %. The quality and safety indicators indicated that it is promising for use in the diet of animals.

"Nowadays we are witnessing an increased interest in phytotherapy and implicitly for herbal products that have lower side effects. One medicinal plant whose popularity has decreased significantly in recent years is Lythrum salicaria L., loosestrife, known in Romanian traditional medicine for its beneficial effects against gastrointestinal diseases. The aim of this study is to evaluate the biological activity of three different extracts (aqueous, alcoholic, acetonic) from the flower tips of Lythrum salicaria L. using the BSLA (Brine Shrimp Lethality Assay) test and the antimicrobial activity of the extracts on two reference bacterial strains which are important for the medical field (Staphylococcus aureus and Escherichia coli) through the diffusimetric method. We demonstrated the fact that the Lythri herba plant product extracts (aqueous, alcoholic, and acetonic) lack acute toxicity, as well as the moderate antibacterial effect on the Gram-positive reference strain, Staphylococcus aureus, thus highlighting the possibility of using the plant in biomedical applications."
ASSESSMENT OF ENVIRONMENTAL CHANGES DURING MINING OF FELDSPAR DEPOSITS IN UKRAINE
Authors: Rudko Georgii , Ozerko Maksym
Published: September 2021

"Possible negative impacts on the environment during mining of feldspar deposits with open-pit and underground mine are defined. The main changes have been identified, which are as follows: air pollution, soil destructions, change of relief, a local decrease in groundwater level, pollution by sewage and waste. Destructions of the soil cover are fixed under the dumps of the quarry and in the path of the movement of quarry equipment. Through the development of a pit and dumps, the primary relief acquires significant changes and the action of forces caused primarily by gravity is activated, aimed at smoothing out negative and positive relief forms. An increase in the height difference from the dump ridge to the bottom of the quarry and the formation of a significant, pronounced depression of the relief redirects the surface runoff, increases its speed, and reduces infiltration into the soil. Mining development caused drainage of groundwater due to its release to the surface and evaporation. Air pollution has a bigger scale than other components of negative impacts. The main impact of mining activities is due to emissions of pollutants into the atmosphere as a result of blowing dust from the surface of dumps and emissions from quarry transport and their deposition on the soil and storage of industrial waste. The main pollutants are inorganic dust with content of SiO2 - 65-82% and Al2O3 - 11-21%. Separately, the article discusses the impact on the environment during multi-components deposits` exploitation, where feldspar concentrates are produced as by-products. Several deposits in Ukraine belong to the group: Bakhtyn (fluorite ores), Nosachivske (titanium-ilmenite ores), Perzhanske deposits of rare metals, Mazurivske (tantalum and niobium ores). Most of them are planned to be mined underground, which saves more land resources in comparison with open workings. The placement of mine shafts and industrial sites for their maintenance requires an area of about 30 hectares. All of them have a complex ore processing with the separation of several concentrates, which necessitates the use of flotation and other reagents. The development of such deposits involves the organization of tailings and circulating water supply of the processing plant."
THREE-DIMENSIONAL SIMULATION OF FLUID FLOW THROUGH A DISCRETE FRACTURE AND MATRIX
Authors: Sharma Kunwar Mrityunjai , Ansari Tariq Anwar
Published: September 2021

The study of fluid flow mechanics in fractured porous rocks is crucial in the area of oil and gas production industries, enhanced geothermal system (EGS), CO2 sequestration, disposal of nuclear waste in deep geological repositories (DGR), etc. There are usually two types of flows in fractured rockmass setting. The dominant flow occurs through the fractures whereas there is also a slow movement of fluid through the matrix block. The fluid movement between fracture and matrix is often continuous across the fracture. The present study focuses on the development of a numerical model which can simulate the flow behavior through fracture and matrix simultaneously, which is also known as dual permeability model. To simulate this problem, a 3D model is built in COMSOL Multiphysics 4.3a where a cylindrical geometry is made, and a fracture is defined parallel to the axis of the geometry. The asperity of the fracture is defined by a variable ‘a’ which varies along the x-axis, in such a way that increases the value of ‘a’ alters the geometry of fracture and increases the roughness of fracture. Darcy flow physics is used to simulate the situation with known parameters like porosity, permeability, storage coefficient, etc. Pressure is applied as a boundary condition at two ends of the geometry which acts as driving force for fluid to flow through the block. The influence of fracture asperity on the flow behavior is examined by doing the parametric study and the study shows the decrement in the velocity magnitude with an increase in asperity. The formation of dual flow velocity regime, one along the defined fracture and the other along with the matrix, indicates the efficiency of the developed dual-porosity and permeability model.

Published: September 2021

Peanuts (Arachis hypogaea L.) are widely grown as a food and oleaginous species. Cultivation of peanuts offers important economic benefits, but one of the most important challenges that growers confront is the fight against destructive diseases. Culture is susceptible to a variety of pathogens, such as bacteria, fungi, viruses, and nematodes, resulting in low yields and degradation of grain quality. Among the most devastating fungal diseases of peanuts are Cercospora arachidicola, Puccinia arachidis, Sclerotium rolfsii which cause substantial loss of production. Loss of yields due to the incidence of peanut disease may be up to 50%. Fungicides can be used to combat fungal diseases, but there are alternative disease control options, such as cultural practices, cultivation of resistant varieties, which can be useful in combating diseases by reducing the frequency of application of fungicides.

Climate change has led to drought, the expansion of desertification, loss of wetlands, loss of biodiversity, declining agricultural output and productivity. In the area of sandy soils in the southwest of Romania, where, compared to the multiannual average, the average air temperature in the May-August period increased by 1.010C and the precipitations recorded insignificant increases (5.97 mm), being very low (227. 82 mm) and unevenly distributed in relation to plant requirements. In these conditions, it is necessary to cultivate some species of plants resistant to drought and to preserve and improve some genetic resources adapted to the arid climate. For the efficient use of the microclimate in the sandy soils areas at the Dabuleni Research & Development Station for Plant Culture on Sands, three genotypes of Aura 26, Ofelia, Doljana were developed, which were studied in a comparison comparative culture with Jiana variety. The production potential of the new varieties (2120-2706 kg / ha) was clearly superior to the control variety, the production differences being significant and very significant.
REDUCTION OF THE VOLUME OF PUMPING OF LIQUID WASTE FROM THE PRODUCTION OF APATITE CONCENTRATE DUE TO THE TECHNOLOGY OF PARTIALLY CLOSED WATER CIRCULATION
Authors: Artemev Alexandr , Biryukov Valentin
Published: September 2021

"The use of recycled water supply technology in mineral dressing plants solves current environmental and economic problems for the mining and processing industry. Usually, water treatment takes a long time and requires constructing large-volume tailing dumps. The paper proposes a technology of a partially closed water circulation with the purification of watered production waste from suspended particles and water-soluble impurities that negatively affect the flotation process, based on the regularities describing the interaction of flocculants with the phases of a heterogeneous system of process waters. The authors have determined the most effective reagents providing optimal indicators of recycled water. The proposed technology is implemented in hardware in a radial thickener and eliminates the discharge of process water into an external tailings dumps facility, which will reduce the area occupied by production waste. Based on the particle size distribution data for various preliminary treatment options, differential and integral particle size distribution curves have been obtained. Analytical expressions of the obtained curves have been used to create discrete functions of volume fractions of particles with different sizes when constructing a model of the initial feed. The hydrodynamic processes of highly diluted suspension flows in the thickener’s body were studied using computational experiments on a model developed in the ANSYS Fluent software package, which is based on the real 3D geometry of a radial thickener. To build the geometry, the authors used a standard module GAMBIT. A computational experiment on cleaning the apatite concentrate discharge was performed on a virtual stand. The distributions of the concentrations of volume fractions of particles and the velocities of their movement in the thickener’s volume were obtained. The results of laboratory studies and computer simulation data allow the authors to tell about the prospect implementation of the technology of intra-plant water circulation, which will reduce by 10% the amount of wastewater discharged into the tailing dump. The use of the most efficient reagents will provide optimal water parameters for the content of suspended particles and hardness cations and, ultimately, will increase the technological and environmental performance of the Khibiny apatite-nepheline ores processing."

Authors: Predajnianska Anna , Takács Ján
Published: September 2021

Thermal baths in Slovakia are producers of wastewater, which hides considerable energy potential. The wastewater from the thermal pools has often exceeds the maximum permissible value of the temperature of the wastewater discharged into the water recipient. As a result, there is undesirable damage to the environment, which results in sanctions for the operators of these facilities. Our aim is to present the concept of a single- and double-step heat recuperation system of waste pool water using applications of various types of heat exchangers or heat pumps. The aim of this application is to ensure a suitable temperature to the discharged waste pool water, efficient use of the energy potential of the waste water and saving of primary energy in the form of geothermal water, thus extending the life of the entire system.

DYNAMIC COEFFICIENT FOR 50 YEARS OF AREA BY CATEGORIES OF THE LAND CADASTER OF THE VOLGA MUNICIPALITY OF THE REPUBLIC OF MARIY EL
Authors: Mazurkin Peter , Efimova Ekaterina
Published: September 2021

In territorial planning and forecasting in the conditions of Russia, it is necessary to take into account the coefficients of dynamism of the area of all lands and by categories of the cadastre. On the example of the Volzhsky district of the Republic of Mari El, it can be seen that agricultural lands have contradictory three fluctuations, which decrease in amplitude until 2070. The largest number of fluctuations over 50 years occurred for two categories of lands: 3 - industrial lands (9 wavelets), 7 - stock (8 fluctuations). The maxima in modulus of the dynamism coefficient are as follows: Category 1 - 0.0799 in 1992; 2 - 0.0177 in 1976; 3 - 0.2384 in 1998; 4 - 0.0018 in 2000; 5 - 0.2714 in 1992; 6 - 0.0160 in 1999; 7 - 6.4204 in 2020; all lands of the Volzhsky region of the RME - 0.0135 in 1977. The most dynamic are stock lands. For agricultural land since 1970, there has been a constant half-life of 5.09737 years. In Russia, the Soviet system of land use in agriculture was preserved, and it was aimed at increasing dynamism. In this case, the first and third fluctuations are directed against (negative sign) the growth of the dynamism coefficient. Not enough attention is paid to the dynamics of agricultural land. The third wave will slow down: 1970 with a period of 4.7 years, in 2020 - 4.3 years, and according to the forecast by 2070 - 3.9 years. Such an increase in vibration frequency is already dangerous. Wavelets # 1 and # 4 of stock lands dynamism become especially dangerous, as they strongly influence the future. Stock wavelets # 3, # 5-7 are a thing of the past. And the rest of the wavelets will continue after 2020. Therefore, stock lands require special attention

Aleppo pine plantations were studied in the region of El Hamimet, the diameter at 1.30m from the ground, the total height of P. halepensis individuals were measured on 4 plots according to an altitudinal gradient. The establishment and interpretation of diameter and height structures are essential for forest management decisions. Knowledge of these parameters is an essential step in their sustainable management. The diameter and height structures were established according to diameter or height classes. The stand on plot 4 is characterized by the lowest diameter and height values. The analysis of the diameter and height structures reveals an increase in the frequency of young individuals. These results contribute to the improvement of the knowledge on the indicators of the current state of the natural Pinus halepensis stands that can be used as a basis for the management of the El Hamimet forest.

Published: September 2021

This work, which was conducted in the Chettaba forest about the viability of the stands can be given by the PHF index, a three-digit index that gives a judgment of the position of the tree (in relation to the others and thus indicating the dominance and the stage of competition or exposure to the dominant stage), of the general shape of the crowns, and of the shape of the shafts, it allows a more detailed silvicultural interpretation to predict the future of the stand and ultimately deduce the viability of the stands. Thus, there is an essential need for a study to be conducted in this regard to understand the existing problems and to bring about proposals on the appropriate intervention in logged surface. The slenderness coefficient of a tree is defined as the ratio of the total height (H) to the diameter at 1.3 m above ground level (d). For the stand level, the slenderness coefficient is calculated using the root mean square diameter and the average tree height as (H/D). It is well known that there is a direct relationship between the stand slenderness coefficient and the risk of stem breakage. It is well known that there is a direct relationship between the stand slenderness coefficient and the risk of stem breakage or tree fall due to abiotic factors such as wind or snow. Sustainability monitoring is crucial to the credibility, validation, value of the options implemented and should be considered early on in the planning process this allows us to say that these stands are stable in the forest and always in the 6 plots studied. Analyses results show a mid-viability for the forest and more of individual listed present instability which is indicated by a medium stability of forests stand’s quality (PHF = 123) and a slenderness coefficient (H/D = 34.47).

Authors: Punanova Svetlana
Published: September 2021

The article, based on the current informational material, provides an overview of the mineral resource complex of Australia and the ways of its development in modern conditions. Modern requirements for the development of the fuel and economic complex of countries are caused by new challenges in connection with the need to follow the Paris Convention on Climate Change and the installation on decarbonization – a significant reduction and then a complete rejection of CO2 emissions from the combustion of hydrocarbons. The work shows that the process of "greening" Australia provides for the creation and implementation of a completely new paradigm for the development of the fuel and energy complex. This is a complete rejection of the extraction and use of coal, an increase in gas production in compliance with environmental requirements, the development and implementation of new technologies, the expansion of gas storage facilities and a network of pipelines, as well as the parallel development and introduction of renewable energy sources.

Authors: Zazharska N. M. , Kibets K. H.
Published: September 2021

Sheep’s milk contains a significant amount of protein, iron, calcium, vitamins A, B and E, as well as phosphorus and magnesium, compared to cow’s milk. The purpose of research was to identify changes in physicochemical parameters, concentrations of immunoglobulins in sheep’s milk and colostrum depending on the day of lactation. The material of the study was 73 samples of ewes milk and colostrum of the Merinolandschaf breed sheep at the private enterprise «Ukrsilgosprom» in Dnipropetrovsk region. It was found that, in terms of organoleptic parameters, the samples of sheep colostrum of the first days after lambing differed significantly from the milk of the subsequent days of lactation. The color of colostrum in the first days was creamy yellow, in all other samples it varied from white to yellowish; smell – pleasant, specific to sheep’s milk, without foreign odors. The taste of colostrum was salty. The consistency of colostrum for the first three days was viscous, especially on the first day, on the following days, it was homogeneous, without mucus, not viscous. It was found that the acidity of sheep colostrum (1–7 days of lactation) ranged from 13.8°T to 34.0°T, density – from 23.2 °A to 94.1 °A. On the second day of ewes lactation, the number of somatic cells (706 ± 221×103 cells / ml) and immunoglobulins (18.72 ± 5.19 mg/ml) decreased by almost half compared with the first day (1 293 ± 231×103 cells / ml and 37.79 ± 7.45 mg/ml, respectively). Electrical conductivity was the only indicator that increased 1.5 times on the second day of lactation (4.23 ± 0.29 mS/m). On the fifth day of lactation, fat indicators (7.13 ± 0.83 %), density (34.90 ± 1.82 °A), acidity (16.7 ± 0.8 °T) almost halved in comparison with characteristics of the first-day colostrum. On the first day after lambing, the highest acidity was observed (33.9 ± 5.8 °T), which was caused by the maximum amount of immunoglobulins (37.79 ± 7.45 mg/ml) in colostrum. After lambing the number of immunoglobulins significantly decreased, on the 6th day – 4.92 ± 1.88 mg/ml (P < 0.001 compared with the first day). The obtained results allow producers of sheep’s milk and cheese to reduce the withstand of the colostrum period and to mix a secret with collected ewe’s milk on the 5th day of lactation.

The amniotic membrane – the innermost of the three membranes, it develops from the fetal ectoderm, it is transparent, avascular and consists of an epithelial cell layer located on the basement membrane and connective tissue stroma. The application efficiency of the amniotic membrane transplantation technique in rabbits with experimental bacterial keratitis has been investigated. The animals were simulated with moderate bacterial keratitis (with preliminary exposure to long-wavelength mercury lamp beams) by the administration to each eye of the Staphylococcus aureus pathogenic strain. On the 14th day, the amniotic membrane was transplanted using two methods: by biological covering with episcleral fixation using simple interrupted sutures and layer-by-layer transplantation with fixation of the membrane within the damage of the cornea with simple interrupted sutures. The degree of the inflammatory process was assessed according to the author’s point scale, which included eight signs. On the 7th, 14th, and 30th days, the experimental animals were euthanized and microscopic examination of the cornea was performed. It was found that on the 7th day of application, complete epithelization of the corneal surface occurred, and on the 30th day, differentiation of its cells into layers. When using the layer-by-layer technique of amniotic membrane transplantation with using simple interrupted sutures, a more pronounced inflammatory reaction was observed in comparison with the biological covering technique. During all observation periods, most experimental animals did not show clinical and morphological signs of inflammatory infiltration. The obtained effect of both methods of amniotic membrane transplantation indicates the effectiveness of using this biological material as the main or supportive in the treatment of severe eye pathologies

Syndrome of anemia in foals manifests itself in the first weeks of their life, and occurs because of oxygen deficiency and excess of carbon dioxide after birth, and caused by a deficiency of trace minerals (iron, copper, cobalt, zinc, iodine, selenium), cyanocobalamin, and folic acid. For the experiment, we selected two groups of foals (age 20–30 days old) with pale conjunctiva. Animals of the experimental group were injected intramuscularly with Vitazal® 5 ml for 6 days. Foals of the control group received 6 ml of Ferrovet® intramuscularly, again after 10 days. The condition of erythrocytopoiesis was studied before drug administration and 30 days after treatment. It was found that 30 days after the administration of the drug in experimental group animals, the number of red blood cells increased by 31.4% (P < 0.001). In the control group, this indicator did not change significantly and did not differ from the values before the treatment. The hemoglobin content in experimental group foals after treatment significantly increased by 28.9% (P < 0,001). In contrast, 66.7% of animals in the control group showed oligochromemia. A similar trend of changes was noted in the determination of the hematocrit value. Changes were also found in the fractional composition of erythrocytes. In particular, after treatment in foals of both groups, the number of «old» erythrocytes decreased (P < 0.05). At the same time, the number of «mature» populations increased only in experimental group foals (P < 0.001). Regarding «young» erythrocyte populations, their number decreased in experimental animals by 8.3% (P < 0.001). However, in foals treated with Ferrovet® (control group), the proportion of «young» cells was increased after treatment, which apparently indicates the activation of proliferation and increased elimination of immature erythrocytes from the bone marrow. The iron content after the introduction of Vitazal® in foals of experimental group significantly increased by 45.6% and on average 26.8 ± 1.07 μmol/l (P < 0,01). In control animals after treatment, the content of this biometal did not change significantly. FTC values in the experimental group, namely TIBC and UIBC in 30 days after treatment significantly decreased (P < 0,001), while in foals of control group they remained unchanged. Iron metabolism directly depends on its transport form - transferrin protein. Throughout the study period, its content in control and experimental group animals was the same. However, the saturation of transferrin with iron in experimental group animals after the introduction of Vitazal® significantly increased by 19.8% and averaged 40.2 ± 1.26% (P < 0.001). In foals that received Ferrovet®, this indicator did not change 1 month after treatment. Thus, the study found a positive antianemic effect of the drug Vitazal® for anemic syndrome in foals.

The results of the study of Saanen goats milk productivity while feeding humic origin organic feed supplement of «VitaHum» are presented in the paper. Studying milk productivity of different goat breeds, as well as using balanced rations of biologically active feed supplements for therapeutic and prophylactic properties and improving metabolic processes and body functions, are important issues for animal breeding industry, since goat husbandry in Ukraine is in a state of formation. «VitaHum» is completely different from existing biologically active peat supplements on the market because it is received not as a result of peat hydrolysis by alkalis or acids, but by a natural way of chelation. It does not contain humic acids sodium salts with alkali residues with which no reaction had taken place, but residues of amino acids, peptides, carboxylic acids and other useful substances in pure «natural» organic form. This feed supplement meets European standards of organic products. It was found that with the industrial technology of the animal management and feeding with mixed diets when using humic origin feed supplement «VitaHum» during the entire lactation period, milk yield was increased by 15.9% or 137.3 kg, milk protein content by 0.11 abs. percent. However, the goats from the control group had the advantage in milk fat content by 0.09 abs. percent (P > 0.999). The maximum average daily milk yield of 3.55 kg was observed in the second experimental group of goats, which received feed supplements «VitaHum» in addition to the main diet. However, as a result of a significant advantage in milk yield from goats of the experimental group, a noticeably higher amount of both milk protein and milk fat mass fraction was obtained by 5.94 kg and 4.63 kg, respectively. Analysis of the qualitative milk composition of the experimental goats showed that the percentage of milk solids non-fat (MSNF) was in the range of 8.45–8.58%, and the content of somatic cells in the milk of control group animals was higher by 7.05%. The qualitative milk composition was quite satisfactory for this breed of goats, as the milk fat mass fraction was 3.94–4.03% and protein one 3.52–3.63%. The ratio of fat and protein at the level of 1.15–1.09 units indicated a good physiological state of the digestive system of the Saanen breed goats.

This study considers signs of a sow that affect the stillborn piglets number in the nest and the likelihood of stillbirth. The animals that were used for this study were kept on the pig farm of «Tavriys’ki svyni» LLC, located in the Skadovsky district (Kherson region, Ukraine). The experimental materials used for this study consisted of 100 animals from productive parent sows of the Large White pig. The reproductive indicators of each animal included in this study were evaluated. The total number of piglets at birth (both live and dead), i.e. total litter size and and sow farrowing number were monitored for the first eight farrows during the period of eleven years (2007–2017). Stillborn piglets were observed in 63.3 ± 1.7% of litter, and their average proportion in the nest was 11.5 ± 0.4%. The proportion of piglets born dead of the total piglets at birth obtained in this study is within the range of 5 to 15%, which has been previously noted for commercial pig farms in other countries. With an increase in the age of the sow (the number of farrowing’s), there was a gradual decrease in the proportion of the litter in which no stillborn piglet was observed (χ2 = 51.35; P < 0.001), and, conversely, the proportion of nests in which 2–4 stillborn piglets were recorded gradually increased (χ2 = 46.32; P < 0.001). The number of stillborn piglets and the frequency of stillborn piglets in the litter tended to increase in sows that had a large litter size at birth (in both cases: P < 0.001).The binary logistic regression analyses indicated that the probability of a piglet being stillborn was significantly associated with the farrowing number of the sow and the total number of piglets in the litter (χ2 = 155.00; P < 0.001). This model predicted well the presence of at least one stillborn piglet per litter (in 86.6% of cases) and more or less adequately predicted its absence (in 42.9%). Our results indicate that there is a significant interaction between the number of farrowing and the total size of the litter when determining the estimate of the proportion of stillborn piglets in the litter. The same predicted estimates can be obtained for a small litter in an older sow, or, conversely, for a large litter in a first-farrowing sow.
