Published: November 2019

The objective of this study was to determine the influence of environmental factors on milk yield in mestizo goats. Analyses of variance was performed for milk yield for test-day in the last third of lactation. The information for this study was taken from the goat production system of the Universidad Francisco de Paula Santander, Seccional Ocaña. The productive system has 90 animals, of which 840 samples of milk belonging to 20 goats were analyzed. Milk yield averages for 5th months lactation and 6th months lactation were 1.29±0.85 kg and 0.95±0.55 kg, with coefficients of variation from 29.11% to 39.46%, respectively. The initial results with the available information suggest that the non-genetic effects of birth month and year (and their interactions) were highly significant. While, the covariable age (linear effect) was not significant in any milk yield for test-day and the quadratic effect was highly significant and significant for fifth and sixth month of lactation, respectively. Consequently, it can be suggested that test-day milk yield in mestizo goats of Ocaña’s region is influenced by non-genetic factors such as the month, year and age of the female at kidding.

Authors: Dubrovskaya A B , Lebedeva L F , Schukis K A
Published: November 2019

The histomorphometric indices (height of the lining (LE) and glandular (GE) epithelium, diameters and density of glands) in endometrial samples (n=21) of young gynecologically healthy mares of 3–8 yo (n = 4) and older problem mares of 12–19 yo (n=7) were studied in estrus and diestrus of one cycle. The height of the LE and GE in aged mares was slightly higher than in young ones, but the difference was not significant. It was found significant differences between groups in diameters and density of glands, more obvious in stratum spongiozum (SS) then in stratum compactum (SC) of endometrium. It has been shown that diameter of endometrial glands in older mares was two to three times larger than in young mares in both estrus (55.9-22.5 μm, p<0.05) and diestrus (62.5-20.1 μm, p <0.01), respectively. The density of glands in SS in young mares in diestrus significantly (p<0.01) increased, compared with this in estrus (9.8-17.5 units/field), while in older mares it almost did not change (11.1-11.3 units/field). The difference of histomorphometric indices in estrus and diestrus can serve as indirect characteristic of an elasticity of an endometrial tissue probably connected with clearance of the uterus. Therefore the double biopsy carried out in estrus and diestrus can be useful for endometrium function assessment in mares.

The paper considers the biological effect of probiotic, enzyme and antibiotic agents on metabolism, efficiency and the element status of chickens. Joint inclusion of soybean-bifidum (0.7 ml/kg of feed), Tselloviridin G20x and Biovit-80 resulted in the increase of the egg weight by 9.8 and 9.0%, respectively in comparison with other groups. The group receiving Sporobacterin (10 ml/kg of feed) with feed was characterized by high fat availability (68%). The greatest conversion of feed gross energy was observed in groups in case of joint inclusion of Tselloviridin with probiotic and antibiotic agents (2.8 and 3.0%) and crude protein (6.2 and 7.0%). The spectral microelement analysis showed that the additional inclusion of biologically active agents caused their redistribution towards the increase of the need for main micronutrients for metabolism. All groups were characterized by a reliable increase of essential and conditional-essential elements such as Ca, K, Mg, Na, P, Cr, Cu, Fe, I, With, Mn, Se, Zn against the background of decrease such toxic elements as As, Al, Ag, Sr, Pb, Cd. The received results confirm the modeling role of probiotics, enzymes and antibiotics in the exchange of micro- and macronutrients.

Published: November 2019

The flood meadow was analyzed in the conditions of radioactive pollution of the territory to study the effect of mineral fertilizer on the efficiency of a meadow and 137Cs content in green grass stand. The experiment was conducted in alluvial meadow sandy soil with 137Cs pollution density of 559-867 kBq/m2 in the subzone of soddy-podzolic soil of southern taiga of the Belarusian province of sod-podszolic slightly humic soils and low-land swamps. The study revealed that the efficiency of natural grass stand is low, the introduction of mineral fertilizer increased the productivity of green grass stand of a meadow to 37 t/hectare with nitrogen fertilizers being the main factors. The decrease of 137Cs in green grass stand triggered the use of potash fertilizer. The use of a flood meadow as a pasture at 137Cs pollution density of over 555 kBq/m2 is impossible for livestock production satisfying norms on 137Cs content in milk and meat without the use of mineral fertilizers.

This research is aimed at studying the influence of no-till technology on the cultivation of Sorghum bicolor using a complex biological substance in comparison with traditional technology. Such parameters as growth and development of plants, yield, the quality of crops based on the quality of previous winter barely crops are considered. The research was carried out in 2016–2018 during a stationary experiment in the steppe of Crimea. The soil of an experimental plot is represented by a mycelial-calcareous black soil. The plough layer contains 4.4 mg of movable phosphates and 39.1 mg of exchangeable potassium per 100 g of soil. The weighted pH average is 7.5. The climate of the steppe agroclimatic region is extremely continental. The annual precipitation is 413 mm. The annual temperature is 10.4 °C. The yield of sorghum cultivated with traditional methods was 1.51 t/ha and 1.44 t/ha in the case of no-till technology (the least significant difference(0.5) is 0.21 t/ha). That means there is no decrease in yield in terms of direct seeding. Despite the lack of tilling in case of direct seeding, the yield is on the same level with both techniques. The use of a complex biological substance increased the yield of sorghum by 0.11 t/ha. The inoculation of seeds in the case of no-till technique helped to positively increase the yield by 0.22 t/ha in comparison with classic technology. In the case of traditional methods, the inoculation of seeds in the biological substance didn’t impact the yield. The mass fraction of ash varied depending on the studied variants from 2.40% to 2.58%, which didn’t provide a positive increase in this parameter. The traditional method, accompanied by the use of a microbial substance, gave a positive increase in the mass fraction of protein by 1.34% in comparison with a control sample and by 1.66% in comparison with direct seeding, accompanied by inoculation. The content of crude fat varied between 3.34% and 4.43%. In the case of no-till + inoculation, this parameter is 0.53% higher than in the case of no-till without inoculation. The traditional seeding with and without inoculation positively decreased the content of crude fat in comparison with direct seeding.

The paper studies the formation and use of water resources on existing irrigation and watering systems (IWS) of Stavropol territory in cause-effect relation with the global problems of Energy, Water and Food defining the tendency of modern development of agricultural production thus meting the vital food needs in social development. Both at the level of the global system “Nature-Society-Person” within terrestrial biosphere and at its hierarchical levels of river basin geosystems, where water resources are formed, agricultural production is carried out on existing IWS, on the example of the Kuban, Terek and Lower Don rivers and with the population of over 23 million people, the modern social development is characterized by a stable tendency towards water finiteness in limited conditions for further development. The analysis of formation of water resources within the spatial limits of basin geosystems and their subsequent use on IWS determines the technological scheme of water use on irrigated lands. The problems of Energy, Water and Food in agricultural production on irrigated lands, as it was established in the processes of their systemic interconnection, interaction and relationship on current IWS of the Great Stavropol Canal have identified the dominant problem, according to which there is a need to take into account the geomorphological characteristics of the earth’s surface topography, geological zoning of the Stavropol territory, development of the methodology to improve energy efficiency of water resources using both non-renewable and renewable sources of energy in accordance with system principles: “system integrity”, “reflection of objective reality”, “ecological suitability”, “vital purposeful activity”. Seven conceptual statements of Ecological Suitability contributing to new ideas for the creation of new and improvement of existing IWS were developed within the concept of “ecological suitability” for IWS operating within NTS “NE – IWS – P” based on basic system principles.

Authors: Tkachenko N A , Koshelev A V
Published: November 2019

Arid pastures, which account for 50-75% of the country’s natural fodder lands, are a unique natural territory of the Russian Federation. However, more than a half of the pasture areas, which are concentrated in the Caspian Sea region, are to some extent degraded. In Volgograd Zavolzhye, due to the plowing of virgin lands, overgrazing and irrational use of agricultural land, an outbreak of deflationary desertification occurred in the 70-80s. At present, the region continues to use its land resources unabatedly, which has led to the intensification of degradation and desertification processes on pastures and a decrease in their productivity. Feed-valuable species have disappeared or become rare. Coenotically and floristically full-membership pasture phytocenoses have become incomplete, biologically impoverished communities, so maintaining ecological balance, productive potential of pasture ecosystems and restoration of their biodiversity is a fundamental task for the region.

Maintenance of tractors in the agricultural enterprises and country farms of the Irkutsk region is carried out by three ways: centralized; decentralized; combined. Each object is expressed by the specific cost of technical tinning in which maintenance-1 and maintenance-2 are considered, and on the decentralized and combined objects in addition – specific costs of maintenance-1 and maintenance-2. The technique of determination of specific cost of maintenance tractors provides obtaining numerical values of an indicator assessment of the choice means maintenance tractors. Results of experimental studies show that the mathematical expectation of specific cost of maintenance tractors by the centralized method has the minimum value (133 rub/engine hour) that is 24.8% less than mathematical expectation by the decentralized method and on 21.1% – by the combined method. This results from the fact that at the decentralized and combined methods the agricultural enterprises in addition have costs of acquisition maintenance unit, its contents and intended usage. When accounting working conditions of the operator in the field – at the decentralized and combined methods of expense also increase at the expense of additional costs respectively of 11.3% and 2.2%. at the combined method additional expenses are 4.8 times less, than at decentralized due to carrying out in field conditions only of maintenance-1.

A structural-topological model is developed, which is presented in the form of connected graphs of the technological flows of grain and spike. Taking into account this model, the use of the main and additional formal features when searching for a non-optimal working element of a combine harvester is justified. For the reaping part, the search for a non-optimal working element is performed on the main formal basis, which characterizes the implementation of the main component of the principle of harmony of the structure. Due to the presence of common arcs of controlled and uncontrolled flows along simple chains, cuts in which two or more working elements, as well as the presence of circulating flows in the threshing machine of the combine, it is necessary to exclude the influence of circulating flows on the process when searching for a non-optimal working element. The search for a non-optimal working element of the thresher is performed on the basis of an additional formal feature, which is characterized by a decrease in the amount of flow along the controlled flow or an increase in the flow through the uncontrolled flow from the circulation flow.
Experimental substantiation of the effective height of a grain falling by a stream of liquid in an ergot release device
Authors: Saitov V E , Farafonov V G , Saitov A V
Published: November 2019

The bunker grain mass coming from the combines to the purification points contains, in addition to grain, weed and harmful impurities, which include toxic sclerotia of ergot, causing disease in people and animals, and even death. Existing grain cleaning machines do not provide for a single technological process the complete release of ergot sclerotium due to the similarity of their properties and the properties of the culture being cleaned. Ergot sclerotia are less dense than grains of rye, wheat, oats and barley, which are mostly affected by ergot. Therefore, the complete isolation of ergot sclerotia from grain in one process can be carried out in aqueous solutions of inorganic salts. In order to mechanize the separation of sclerotium ergot from the grain by the wet method and to develop a device for cleaning the grain material that is not complicated in design with low energy intensity of the technological process in comparison with the existing grain cleaning machines, practical experiments were carried out on immersion of winter rye grain of the Falenskaya 4 variety into the water and in the aqueous salt solution sodium chloride (NaCl). It has been established that the effective height of the location of the loading bin relative to the surface of the aqueous solution of salt in the bath of the device for extracting harmful impurities from the grain material by the wet method is 40.0–60.0×10−3 m, at which undesirable capture of the air bubble by the grains does not occur. This determines the improvement of the quality of the technological process of cleaning the grain from harmful impurities of the developed machine for the separation of ergot.

Authors: Berdennikov E A , Smirnov A M
Published: November 2019

Nowadays, a case-by case approach to optimizing and rationalizing the machine usage parameters is relevant. One of the ways to improve the efficiency of the machine and tractor fleet operation with regard to individual reliability indicators is to assess the rational tractor service life. According to the proposed model, the tractor is to be decommissioned when it ceases making a profit. Aiming to test the proposed model, ten 3 kN class tractors, operated in agricultural enterprises in the Vologda district of the Vologda region, have been under research for five years. As a result, it has been found out that all the tractors under study have different reliability and, consequently, different rational service life periods.

Published: November 2019

The lands that turned out to be unclaimed for agrarian production pass into the category of waste, due to the spread of weeds on them. At the first stage, such lands pass through a wild grass stage with typical weed-field vegetation, where annual dicotyledons predominate, subsequently these plants are supplanted by perennial grasses, overgrown with shrubs and tree growth, and waste lands become uncultivated deposits. The presence of vegetation cover with a height of 1-1.7 m not only complicates the conduct of mechanical tillage, but also requires large amounts of energy. On lands left out of agricultural use, there is a noticeable change in soil properties. All agrochemical parameters of deposits have a lower value than arable land. On abandoned fields, along with a decrease in nutrients in the soil, there is a change in water and air conditions, which complicates the process of tilling. Entering abandoned fields in crop rotation for the production of agricultural products is an important economic problem of the day. The aim of the work is to develop the technology of the main tillage and dump plow for its implementation, ensuring the incorporation of tall plants in abandoned fields at low energy costs and high agrotechnical indicators.

The paper discusses a synergistic effect of the SHF electromagnetic field and high moisture content of the bran product with incorporated magnetic microparticles. The microparticles were standardized: the Fe size was 12.5–50 μm and the pycnometric density was 3.40 cm3. It was found that optimal processing conditions provide a significant increase in the temperature indicators of the experimental complex (EC) to 65 °C and 45% moisture content. It was shown that the SHF electromagnetic effect on the experimental complex allows production of a single complex of organic matter and magnetic agglomerates within a short period of time and energy range with the porosity of samples increased up to 74.14%. A microscope was used to examine the samples of the experimental complex and to analyze the microstructure of the resulting sample, where the structure was modified as a result of thermal exposure and it caused sintering of magnetic agglomerates and organic matter. The study results showed the necessity for further investigation of the synergistic effect of EC using the SHF electromagnetic method.

Published: November 2019

Nanoparticles of titanium dioxide (NP-TiO2) are the most widely used nanomaterial in various industries. However, the safety of NP-TiO2 has not been studied in full. The research was carried out with the «Wistar» rats (n=21). The nanoparticles of titanium dioxide obtained by the plasma chemical synthesis, were once administered intraperitoneally at doses of 15 mg/kg and 75 mg/kg (90 nm). On the 1st, 7th, and 14th days of the experiment, the emotional and motion activity was assessed using the Open Field test and the Infrared Actimeter system; the blood sampling was performed to evaluate the hematological and biochemical parameters. It was revealed that a single intraperitoneal injection of titanium dioxide nanoparticles at doses of 15 mg/kg and 75 mg/kg resulted the changes in the behavioral responses of animals, which were accompanied throughout the experiment by the increased motion activity and emotional stress. There were noted the changes in protein, fat and mineral metabolism, the enzymatic activity increased. Despite the fact that the administered doses were significantly different, the effects of exposure were similar, that indicates the absence of a dose-dependent effect. The greatest effect of exposure was recorded at the first day of the experiment.

Published: November 2019

Synthesized CoFe2O4 nanopowders in an aqueous extract from the leaves of Petroselinum crispum (“Green” synthesis) in an acidic and alkaline medium. Physical and chemical certification of the synthesized nanomaterials by UV spectrophotometry and scanning electron microscopy (SEM) was carried out. According to the UV spectra of CoFe2O4, obtained in an acidic medium, had a small shoulder at 242 nm and a peak at 292 nm, while the particles of alkaline nature had a plateau starting from 229 nm and a peak at 366 nm. SEM found that the synthesis environment also affects the morphology and size of CoFe2O4 bimetallic powders: during the synthesis in an alkaline medium, the particles were hemispherical in size from 30 to 100 nm, and in a slightly acidic medium (pH = 2), larger particles with cut diamond. The biological activity of cobalt ferrate was shown on the tolerance dynamics of Triticum vulgare L. plants (wheat). Wheat plants were grown in a hydroponic medium with the addition of CoFe2O4 nanoparticles in the range from 10–5 to 10–1 M to 14 days. CoFe2O4 powders of an acidic nature at concentrations of 10–2, 10–3, and 10–5 M reliably increased seed germination relative to intact samples by 48, 37, and 11%, respectively. In turn, CoFe2O4, synthesized in an alkaline medium, increased the index at dilutions of 10-3 and 10-4 M to 4 and 28%. A detailed analysis of metric indicators of T. vulgare seedlings after 14 days of exposure to CoFe2O4 allowed us to establish a higher resistance of test plants to nanopowders synthesized in an acidic medium. So, when exposed to particles synthesized in an acidic medium, in concentrations from 10-1 M to 10-5 M, an increase in the plant tolerance index of plants from 4 to 14% of the control was recorded. Alkaline CoFe2O4, under the same conditions, increased the rate from 1.2 to 16%. The intensity of the effect on the pigment apparatus of T. vulgare plants also depended on the synthesis conditions for CoFe2O4: at pH = 2, the amount of chlorophyll a decreased by no more than 2 times relative to the control, at pH = 9 - from 2 to 5 times (P≤0, 05).

The article is devoted to the export of agricultural products and foodstuffs of Russia. The assumption of perspective development of the market of agricultural products and food, including organic products for the Russian agriculture, mechanisms of development of export-oriented agriculture are proposed. The research substantiates the resource potential of the Russian regions of agro-industrial direction, in particular, the Altai Territory, and the prospects for the expansion of the production of ecologically clean, organic agricultural products and foodstuffs, their exports in order to improve the nutrition quality of population not only in Russia, but also in other countries. In this regard, the development of multilateral commercial and economic cooperation among the countries of the Shanghai Cooperation Organization (SCO), which includes China, Russia, Kazakhstan, Tajikistan, Kyrgyzstan, Uzbekistan, India and Pakistan, is reasoned. In recent years, within the framework of this organization, the creation of a free trade zone, as well as infrastructure for trade and investment, is expected. It is economically feasible to attract business investments of these countries in the regions of Siberia and the Far East in order to create joint processing agro-industrial enterprises, including enterprises for advanced processing of grain in Altai. At the same time, it is necessary to conduct scientific research in the direction of substantiating strategic vectors and mechanisms for international cooperation in order to improve the quality of nutrition of population within individual countries and international associations.

This article discusses the occurrence of toxic wastewater from the production of ethylenediamine by aminating 1, 2-dichloroethane with ammonia. It is shown that wastewater from ethylenediamine production is formed at the stages of evaporation of ethylenediamine dihydrochloride and rectification of a mixture of amines obtained as a result of evaporation. In the first case, the wastewater contains a saturated NaCl solution with a content of 1÷2% of polyethylene polyamines, and in the second case, the wastewater is a solution containing about 1% of ethylenediamine and about 2% of ammonia. To study the toxicity of these wastewaters, watercress (Lepidium sativium) varieties Zabava and Krupnolistovoy were used. The assessment of toxic properties of wastewater was carried out according to such indicators as seed germination, the average length of seedlings and the dry weight of seedlings. It is revealed that the studied wastewaters have an acute toxic effect on the watercress of both varieties. It is shown that the regression equations obtained for the dry weight of seedlings and seed germination, in contrast to the length of the seedlings, do not adequately describe the experimental results and cannot be used to determine the safe dilution ratio. The safe dilution ratio, calculated using the average length of seedlings, ranges from 489.1 to 892.9 for various runoffs and watercress varieties. It is shown that the most toxic is the runoff containing a saturated NaCl solution with a content of 1÷2% polyethylene polyamines. Zabava is the most sensitive to the degree of effluent toxicity.

The article is devoted to using wastewater of the Orenburg Gas Chemical Complex in the amount of up to 7.0 million m3 for irrigating agricultural crops with the purpose of additional cleaning of wastewater and increasing the yield of agricultural crops. Analyzing the obtained data, it is shown that in the arid climate with rainfall deficiency, the use of wastewater for irrigation of forage crops is the best variant in providing the necessary measures for preserving the ecological status of the agricultural sewage farms (ASF). As a result of own research over years 1982 – 2015, the influence on the ecological state of ASF soils was detected in the form of deterioration of the water-physical properties and increased content of easily soluble salts in the soil; with that, the content of gross and mobile forms of heavy metals is significantly lower than MPC, but slightly above the background values, which does not affect the quality of sorghum harvest. Pollutants accumulate in the top layer of soil; therefore, the impact on surface water bodies has not been established. The authors suppose that maintaining the ecological state of ASF requires some measures like the introduction of calcium-containing substances and optimization of the irrigation conditions. The practical importance of scientific research is that based on the obtained results, a project of ASF soil rehabilitation has been developed and put into production.

Benthic foraminifera of the Maastrichtian sediments from the Maliboğazi (Kalecik, Ankara) and Irmak (Kırıkkale) areas in Türkiye
Authors: Gormus Muhittin , Akoraler Hacer
Published: November 2019

The investigation focuses on benthic foraminifera and their paleoecology, particularly on the Orbitoides genus in the Maaastrichtian sediments from the northern and western Ankara City (Turkey). The hard and soft rock samples from two measured sections, namely as Malibogazi (N Ankara) and Daryaka-Irmak (W Ankara, Kirikkale) were evaluated. More than one hundred equatorial and axial sections of the Orbitoides genus were prepared. The benthic foraminifera of the Maastrichtian sediments are as follows: Dorothia sp., Marssonella sp., Lenticulina sp., Saracenaria sp., Oolina sp., Cibicides sp., Gavelinella sp., Orbitoides apiculatus, O. gruenbachensis, O. medius, Pseudomphalocyclus sp., Omphalocyclus macroporus, Lepidorbitoides sp., Sirtina sp., Sulcoperculina globosa, S. vermunti, Siderolites calcitrapoides, Laffitteina mengaudi, Laffitteina sp. In the Malibogazi area, biometric data based on the internal and external parameters of the Orbitoides genus present reliable interpretations for paleoecological approaches of the Maastrichtian time. The calcareous siliciclastics comprise abundant Orbitoides apiculatus and O. gruenbachensis species. We have identified two ichnospecies as Maeandropolydora osmaneliensis and Curvichnus semorbis in the Orbitoides tests. It is thought that meandered microboring activity are related to parasitic life modes while cave shaped ones are associated with hermit type life modes. Orbitoides bearing siliciclastics overlies reefal sediments including biostromal limestones with rich rudist fauna, Thalassoniodes rich carbonates and massive, thick bedded limestones in the Maliboğazi area. In contrast, siliciclastics indicating open sea sediments outcrop widespreadly in the Irmak area. The obtained stratigraphical, sedimantological and paleontological data show that northern part of the Ankara was shallower than western part of the Ankara during the late Maastrichtian.
Passive Seismic Tomography as a Tool of Rock Burst Hazard Prognosis in Copper Ore Mine in Poland
Authors: Gogolewska Anna Barbara , Smolak Daria
Published: November 2019

In Poland, underground mines of copper ores, which belong to KGHM Polish Copper JSC, have been struggling with seismic dynamic events such as tremors and rock bursts since almost the first years of exploitation i.e. the 70s of the twentieth century. Mining activities infringe the original stress balance and make the rock mass accumulate energy and then release it, which triggers seismic hazard even far away from a tremor epicentre. Therefore, prediction of the position, time and energy of tremors plays a significant role in mining operation especially in work safety. For this purpose, many observation methods including seismology, seismic, geotechnical-geological monitoring, are used; unfortunately, most of them help describe the state of the rock mass after but not prior to the occurrence of the seismic phenomena. Only passive seismic tomography is promising since it can be used to forecast, to some extent, the location of places of seismic energy excessive accumulation. In this method, on the basis of seismic events recorded in a given period, zones of high and low seismic wave velocity are determined (calculated), which in the near future may pose areas of increased seismic activity. The phenomenon of the increase of seismic longitudinal wave velocity with the increase of stress in rocks makes the ground of tomography calculations. The prime purpose of the paper is to assess passive seismic tomography as a means for forecasting and evaluation of seismic and rock burst hazard. To accomplish this, the analysis of seismic activity and archival seismic tomography results (seismic wave velocity zones and seismic anomaly zones) with reference to seismic phenomena, their energy, number and location were carried out. On the basis of obtained the results, the effectiveness of seismic hazard forecast with the use of passive seismic tomography was assessed. The research was carried out for one mining division of the Polkowice-Sieroszowice mine and covered ten years. This division was selected due to its high seismic activity and the permanent use of the passive seismic tomography to assess the seismic risk. Linear correlation and determination coefficients between seismic activity characteristics and seismic anomaly as well as longitudinal wave velocity were calculated. It was found that in the study area the effectiveness of passive seismic tomography in forecasting the seismic hazard is relatively satisfying since about half of the tremors were located within zones of high seismic activity (substantial velocity of P-waves and seismic positive anomalies)..
