Published: February 2020

Recently the livestock farmers of Baltasinsky, Kukmorsky, Sabinsky, Alkeevsky and other regions of the Republic of Tatarstan have increasingly frequently faced the young cattle diseases associated with pathology of the gastrointestinal tract that have not been treated by the classical scheme of diseases with diarrhea symptoms.Sick calves had acute and subacute catarrhal gastroenteritis mainly in the later stages of which accompanied by the inflammatory process in the posterior segment of the small intestine. The manifestations of structural changes in the subepithelial lymphoid tissue of the intestine, in the stagnant digestive glands and regional lymph nodes were increased with a severity level of the clinical symptoms of the disease.In this regard, in order to obtain a complete picture of the effect of cryptosporidiosis invasion on the peripheral blood condition of sick calves, hematological studies were conducted in the dynamics of the development of the infectious process. We have studied the content of red blood cells, white blood cells including lymphocytes, granulocytes, as well as monocytes and hemoglobin on the 7th, 14th and 30th days of the experiment. Hematological studies of calves infected with spontaneous invasion of cryptosporidiosis, and after treatment, had been carried out in 2016 2018 at the OJSC “KukmorAgroChimService” in the Kukmorsky district of the Republic of Tatarstan in the Russian federation. Cryptosporidiosis clinically insane calves had erythropenia and leukocytopenia in the blood and low hemoglobin. Reduced oxygen capacity of the blood contributed to the development of the secondary destructive changes in the organs of hematopoietic organs. The established dynamics of a decrease in the content of eosinophilic granulocytes in the blood of calves in the first and especially in the second groups indicated a high therapeutic effect of the drugs used. Starting from the 7th day, due to the therapeutic effect of the tested medications in the places of the pathogenic effects of cryptosporidia, regenerative processes were intensified. It affected the morphological parameters of the blood.

Published: February 2020

Modern crop cultivation technologies use biological products with adaptogenic and biofungicidal properties. The article studies the influence of Streptomyces sp on the growth, development, and formation of buckwheat crops. The treatment of seeds with biological products reduces field germination; however, their environmental sustainability increases. The maximum grain yield of 249.7 g/m2 was obtained when applying actinomycetes in the amount of 2.0 l per ton of seeds. The ability of the biological product to preserve the activity of nodes and shoots increased the number of inflorescences. The dynamics of biosynthesis and the fractional composition of chlorophyll in the leaves were studied. The biosynthesis of pigments was the most intensive during during seed treatment with Streptomyces sp in the amount of 1.0 to 1.5 l/t of seeds. The relative amount of chlorophyll “a” to chlorophyll “b” during the intensive development and mass flowering was relatively stable (2.5 ... 2.7). In the phase of fruit formation, in the control plants and plants treated with Rizoplan and actinomycetes (0.5 l/t), the proportion of chlorophyll b increased. In variants with a lower proportion of chlorophyll “b”, the seed productivity of plants was higher.

Published: February 2020

In 2018, studies were conducted to assess the impact of foliar feeding with complex fertilizers on the yield and grain quality of two soybean varieties. Weather conditions throughout the year were noted periodically dry in May, June and August. Metallocene® fertilizers with different mineral nutrition elements were used for soybean spraying. The fertilizers were used for spraying in the soybean beginning bloom stage. Epy control served as a variant without foliar feeding. It was found that the variety Annushka in the conditions of 2018 was more productive than the variety Milyaushaa. The difference between the varieties in the control was 0.3 t/ha. Low yield in the control sample was associated with the negative effect of drought on the existing root system and the nudeles on it. Spraying Annushka crops by Metallocene® A with copper has high positive effect on the yield. The yield increase from this fertilizer was 0.72 t/ha. In case with Milyaushaa, the best indicators were achieved by Metallocene® D spraying with manganese. In case the yield increased by 0.79 t/ha. The use of foliar feeding had positive effect on soybean seed size. The maximum 1000 seed weight Annushka was for Metallocene® A with copper. For Milyaushaa the largest seeds were when using Metallocene® D with manganese. Foliar feeding by Metallocene® D with manganese had positive effect on phosphorus accumulation in seeds.

Published: February 2020

The results of many years of original research based on soil-ecological monitoring showed the development of degradation processes of previously drained peat soils of the Ryazan Meshchera. Structural amelioration (sanding) of peat soils had some positive effect. The aim of the research was to study the properties of the dried peat soil at reclamation site Tinki-II in the settlement of Polkovo, Ryazan District of Ryazan Region, as a result of sanding. The most common type of German mixed-layer sanding was used in investigations. The methodology was based on the principle of comparing the state of dried peat soil before and after sanding. The content of the less than 0.01 mm fractions was 4.3 %, the rest consisted of particles from 0.25 to 0.05 mm; the pH of the salt extract was 5.7. Mineral fertilizers were applied in the experiment in small quantities: ammonium nitrate – 180 g, superphosphate – 185 g and potassium sulfate – 260 g. The water supply was atmospheric-ground. Variant 2 was more effective – sanding with a dose of 1200 t/ha for sluicing and maintaining GWL = 90 cm, as evidenced by improved water-physical properties of the soil: the total porosity increased by 5 %; the total water capacity decreased from 270 to 70%, that was almost 4 times. Keywords: peat soil, degradation, sluicing, sanding, yield, potato.

Published: February 2020

The study has been carried out at two livestock complexes specializing in the production of beef to investigate the causes of non-productive retirement of animals. The structure of the causes of death or necessary slaughter of young cattle was determined by the results of pathological autopsy (n = 2816). Moreover, it was revealed that in 83.5 % of the animals, morphological changes in the respiratory organs prevailed, which in 40.2 % of the cases were thanatogenetically significant. The pathology of the digestive system was found in 29.6 % of animals, and in 14.9 % of cases they caused death. Pathology of the kidneys and urinary tract most often occurred at the age of 4–6 months and caused the retirement of 7.6–9.4 % of the animals. The role of cardiovascular pathology in the structure of the causes of retirement increases in young animals aged 8–11 months, while that of diseases of the joints and distal extremities rises at the final stage of their fattening. Clinical and expert evaluation of the activity of veterinary specialists (n = 12) showed that they correctly identified the underlying disease in 74 %, concomitant pathologies in 17.9 %, and complications in 5 % of diseased. Therefore, one of the problems of diagnosing diseases in young cattle during the period of growing and fattening is an incomplete diagnosis due to the low detection rate of concomitant pathologies and complications, some of which are of decisive thanatogenetic significance.

Published: February 2020

The article discusses prospects for use of the theory of adaptogens in demand in medicine and in the fish breeding practice. The obtained results show that the adaptogens use at the early stages of catfish ontogenesis (Clarias Gariepinus, Burchell 1822) can cause the condition of nonspecific increased resistance and expand the adaptive flexibility range of this specie. Adaptogen trekrezan used in our experiments (Oxyethylammonium methylphenoxiacetate) is a synthetic analogue of the natural ginseng. Its application in the embryo culture process has shown positive results. It has reduced the level of the developmental anomaly, increased the first stage larvae hatching and their viability, significantly decreased the mortality rate and reduced the level of cannibalism common for catfish larvae. We have determined that the larvae breeding in the trekrezan medium has considerably increased their growth rate, and weight gain. The obtained results are new, and the adaptogens use at the early stages of ontogenesis in industrial catfish aquaculture is recommended. The Russian Foundation for Basic Research has supported our study with the grant No. 18-416-730005.

Functional properties of platelets in piglets when changing methods of nutrition
Authors: Zavalishina Svetlana Yu.
Published: February 2020

A functionally significant element in ensuring homeostasis of the internal environment of an animal organism is platelets. The state of their activity greatly influences the rheology of blood in small vessels and, thus, the metabolism in tissues. It becomes clear that the process of growth and development of piglets at any age substantially depends on the level of their activity. In this regard, the assessment of agerelated changes in platelet activity in piglets during their early ontogenesis is of great importance. In the work performed, it was found that in piglets during the dairy and vegetable nutrition phase there is an increase in the adhesive, aggregation and secretory properties of platelets. The leading cause of these changes can be the enhancement of receptor processes and activation of the work of post-receptor mechanisms of information transfer in platelets. This is noted in piglets during the milk-plant nutrition phase simultaneously for both strong and weak aggregation inducers. The growth of platelet activity in piglets found during the observation period apparently was due to the intensification of thromboxane generation in platelets as a result of the increased activity of their cyclooxygenase and thromboxane synthetase, as well as an increase in the secretion of ADP molecules from them. The increase in the severity of the hemostatic properties of platelets in piglets during the milk-plant nutrition phase seems to be a serious regulator of their microcirculation and metabolism processes in any environmental conditions.
Functional condition of the hemostasis in newborn calves with signs of iron deficiency, background to ferroglucin
Authors: Zavalishina Svetlana Yu.
Published: February 2020

Further improvement of approaches to breeding and raising cattle is possible with reliance on continuously collected information about its physiology at any age. Their active use in practice is already yielding positive results on the intensification of cattle breeding in different countries of the world. Unfortunately, still not all farms manage to provide optimum housing and feeding for pregnant cows. For this reason, it is still not uncommon for newborn calves to show signs of iron deficiency. In this work, the use of ferroglucin in 38 newborn calves with iron deficiency achieved an improvement in their general condition, normalization of serum iron levels, a slight increase in plasma antioxidant protection levels and a decrease in the intensity of lipid peroxidation in it. Excessive hemocoagulation and platelet activity and reduced hemostatic properties of the vascular wall in the outcome of these calves experienced some positive dynamics against the background of the use of ferroglucin. The weakness of the achieved dynamics of the indicators taken into account indicated the preservation of hemostatic disorders in animals that received ferroglucin, and their risk of microthrombosis, which can slow down their growth and development.

Published: February 2020

Potato production is associated with high energy and labor costs, and the final part (harvesting) accounts for the bulk of the costs. When designing potato harvesting technology, the main focus is on the separation of soil impurities, which make up about 97 % with a high yield of 300 kg/ha, and lower yields increase them to 98–99 %. Nowadays, with the advent of new materials and new technologies in agricultural engineering, there is modernization of existing structures using innovative materials, as a result of which some new and having no analogues models are created that can improve the quality of the machine, increase its service life, and reduce energy costs. The effectiveness of the working bodies of potato harvesters determines the ratio of the separating ability of the working body to its energy consumption. As a result of the studies, power parameters and the separating ability of the main working bodies were generalized. The modernization of the separating elevator consists in replacing the metal rods of an existing elevator apron with a similar apron with rods of some composite material. This modernization can significantly reduce the mass of the working body and the whole combine as a whole and reduce energy consumption.

Published: February 2020

It is known that the majority of pathological processes take place against the background of formation of active oxygen species and intensification of free radical oxidation of bio-substrates. In response to this, the antioxidant system of the cell is activated, and the glutathione system is an important link in this system. The latter can take part in the maintenance of the optimal state of biomembranes, in the processes of detoxification, antioxidant protection, etc. The biological role of glutathione reductase is to maintain high intracellular concentration of reduced glutathione. The aim of our study was to study the relationship between the distribution of glutathione reductase activity in blood serum and rat tissues. In order to achieve the goal of the study the following tasks were solved: the activity of glutathione reductase in blood serum and tissues of liver, brain, heart, as well as in skeletal muscle tissues of rats was determined; the interrelation of the activity distribution of glutathione reductase in blood serum and tissues of rats was revealed. The article presents the results of nonparametric correlation analysis to assess the relationship between the distribution of glutathione reductase activity in blood serum and tissues of small experimental animals.

Authors: Vasilev Roman , Vasileva Irina , Yugatova Natalya , Troshin Eugene
Published: February 2020

The paper studies the impact of selenium organic preparation DAFS-25k on thyroid capacity in pregnant cows. A stud farm which the work is done in is a biogeochemical province distinguished by a sharp deficit of selenium and iodine in the diet. DAFS-25k had been implanted into the animals subcutaneously during 1 month 30 days before the predicted calving. A sterile 0.6 % DAFS-25k oil solution was used in doses containing 2 mg/cow/day, 6 mg/cow/day and 12 mg/cow/day. It was found that the cows’ diet is deficient in iodine and selenium by 63 and 82 % respectively. Daily use of selenium in DAFS-25k in the dose range causes a decrease in the concentration of free thyroxine due to deiodination activating by selenium dependent deiodinases of the first and second types. Consequently, there is a progressive increase in the blood content of total triiodothyronine in all experimental animals as relating to the background values. In this case, the concentration of thyroid-stimulating hormone decreases in blood serum by the 30th day according to the principle of negative feedback. In control animals, an increase in the serum concentration of thyroid-stimulating hormone reached the point 1.8 by the 30th day, total triiodothyronine increased by 14 and 19 % by the 21st day and the 30th day respectively, while the concentration of free thyroxine was reduced by 19 % by the 30th day. The use of selenium in the setting of iodine deficiency leads to aggravation of iodine deficiency.

Authors: Nikolaev Semen , Konopeltsev Igor
Published: February 2020

The search for alternative drugs for treating inflammatory diseases of bacterial etiology in high yielding cows that do not cause antibiotic resistance and do not reduce the quality of the obtained products is an urgent task for veterinary obstetrics. As one of this remedy, the authors have tested ozonated flaxseed oil (OFO), obtained by bubbling flaxseed oil with an ozon-oxygen mixture for four hours by means of ceramic spray with the ozone concentration being 30 mg / liter. During the bacteriological studies, it was found out that a two-hour incubation of the drug with a bacterial culture inhibits the growth of Staphylococcus aureus and Escherichia coli at a dilution of 108 microbial bodies (m.b.) in ml, bacteria of the genus Citrobacter at a concentration of 106 m.b. and Streptococcus agalactiae at the dilution of 107 m.b. in ml. The therapeutic efficiency of OFO was evaluated on the basis of using it for the cows of the Kholmogory Holstein breed, with the signs of postpartum septic catarrhal endometritis. For this purpose, 2 groups of animals were formed on the basis of analogues. For treating the cows of the experimental group the OFO has been used, and the cows of the control group were treated with the antibiotic containing the drug tylosinocar. For 5 months of observation, all animals were fertilized in the control group, and in the group where OFO was used this number was 93.3 %. Moreover, in the experimental group 47 % of the cows were fertilized after the first insemination, which is 27 % more in comparison with the control group. The duration from calving to fertilization in the group where OFO was used averaged 104 days, which is 21 days less (P <0.05) compared to the control group. Studies have shown that the use of OFO did not lead to the inhibitors emergence in milk in the experimental group of cows.

Published: February 2020

One of the main tasks of drip irrigation is to predict the geometric parameters of the moisture contours by estimating the impact of the water rate and the irrigation water on the moisture distribution in the soil. In this paper the soil water retention curve and function of moisture conductivity are used to simulate the process of moisture movement taking into account both the state and the type of soil. A software tool has been developed to automate calculations and visualize them. One of the main advantages of this software tool is that it allows using three-dimensional arrays of porosity values, specific surface area and initial soil moisture for each elementary volume of soil. The results of simulating various initial conditions make it possible to form contours and maintain optimum soil moisture right in the area of the plant root zone development. The correspondence of the simulation results to real data was verified by a series of laboratory and field experiments having light-gray forest soil. The calculated coefficients of determination have average values, that are quite high for such tasks, namely 0.68 (horizontal surfaces) and 0.72 (inclined surfaces).

Published: February 2020

The article presents the possibilities of obtaining useful products from poultry and oil industry wastes using Mephosphon biologically active agent. The use of an aqueous solution of the Mephosphone preparation in ultra-low concentrations (10−6–10−8%) allowed obtaining the Compost UP-1 product from chicken manure and the Meliorant product from drilling waste. The Compost UP-1 belongs to the 4th hazard class in terms of physico-chemical and sanitary-biological characteristics, and the Meliorant product in terms of pollutant content belongs to the 5th hazard class. Studies on the influence of useful products derived from waste were carried out in the field in the experimental fields of the Laishevsky district of the Republic of Tatarstan. The Compost UP-1 and Meliorant products were introduced during pre-sowing cultivation in an amount of 26 t/ha and 1.3 t/ha, respectively. For comparison, during the research, reference plots were organized (Reference). The seeds were spring wheat of the Yoldyz variety (Compost UP-1) and Idelle (Meliorant). The analysis of growth and productivity indicators of plants grown in different areas showed that the use of the obtained products improved soil fertility: the introduction of the Meliorant product optimizes soil pH, activates mass transfer processes, and the introduction of the Compost UP-1 product increases the content of nutrients (N, P, K). So at the tillering stage in the section with Compost UP-1, the average phytomass per unit length of plants was 1.8 times higher than in the Reference. The use of Compost UP-1 leads to a significant improvement in grain quality: the mass fraction of protein increased by 32 %, vitreous content by 60 %, and the content of crude gluten by 34 %.

Studies to identify the effectiveness of bioagents and adaptogenic preparations on plantings of potatoes of the Vineta variety were carried out on gray forest medium loam granulometric composition of the soil of the Zemlyaki farm in the Nizhnekamsk district of the Republic of Tatarstan. Field experiments were carried out in 2019 by employees of the Department of Plant Growing and Horticulture of Kazan State Agrarian University. The humus content in the arable layer of soil according to Tyurin is 3.35 %, pH is 5.7, easily hydrolyzable nitrogen is 112 mg/kg of soil, mobile phosphorus is 156 mg/kg, exchange potassium is 136 mg/kg of soil, molybdenum is 0.07, copper is 0.52, boron – 0.7, zinc – 4.82 mg/kg. The paper presents the results of studies on the effect of the preparation RECB-95B obtained on the basis of bacteria Bacillus subtilus, RECB-44 – Pseudomonas fluorescens, RECB-50B – Bacillus sp. and RECB-74B — derived from the fungus Trichoderma viride for antagonistic activity against pathogens. Based on the results of our preliminary studies, we selected these preparations for preplant treatment of tubers and vegetative plants. It was found that the most effective option for planting potatoes was the treatment of tubers before planting with the strain RECB-50B (2 l/t) + adaptogen in combination with three times spraying during the growing season RECB-95B, RECB-4B, RECB-50B using them together with adaptogen. Our data show that the mass of tubers does not always correspond to the number of stems and tubers, however, in variants 7 and 8 with a high mass of tubers, a larger number of stems and tubers per bush was noted. Less nitrates 73 mg/kg contained tubers from the variant when used for processing tubers of strain RECB – 50 B (2 l/t) and triple treatment of plants during the growing season with bioagents RECB – 95 B (0.5 l/ha), RECB – 44 B (0.5 l/ha), RECB – 50 B (1.0 l/ha). The use of these drugs in conjunction with the adaptogen led to an increase in the number of nitrates in the tubers. A higher starch content in tubers of 13.02 and 13.01 % was observed when treating the tubers of the drug Maxim (0.2 l/t) and strain RECB – 50 B (2 l/t) and triple treatment of plants during the growing season with bioagents RECB – 95 B (0.5 l/ha ), RECB – 44 B (0.5 l/ha), RECB – 50 B (1.0 l/ha). In the dry matter, the starch content was higher when the tubers were treated with rhizoplan and amounted to 63.38 %.

The modern direction of landscape architecture to creation of ecological and naturalistic plant communities of perennial herbaceous species for the design of park walking routes in the style of “naturgarten” is highlighted in this paper. The principles of selection of herbaceous perennials developed by Russian scientists for planting in urban environments, as well as the principles of creating combinatorial plantings are given. The range of perennial herbaceous plants proposed to create a ground cover along the park walking route with an indication of their environmental requirements is presented in the Tables. The type and storey of plantings where these plants can be used, the flowering period and in the note the additional features of a particular species are indicated. This material can be further used in the design of structural modules of the ground cover according to the type of natural phytocoenoses for park areas with different environmental conditions.

Experimental samples of biological products based on endophytic microorganism strains were tested on sugar beet root plants. The studies were carried out at ZAI Agrofirm LLC, Zay District, the Republic of Tatarstan. The most effective preparations applied at the early stages (3–4 leaf phase) were RECB – 31 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 44 B (2.0 l/ha), RECB – 50 B (2.0 l/ha), and RECB – 74 B (2.0 l/ha). Biological preparations applied in the row closing leaf phase have an advantage over chemical preparations when applying RECB – 14 B (1.5 l/ha), RECB – 31 B (1.5 l/ha), RECB – 74 B (1.5 l/ha), RECB – 74 B (2.0 l/ha). At the late vegetation stages, experimental preparations increased the yield. A significant increase was observed when applying RECB – 95 B (1.5 l/ha).

The physiological aspects of the implementation of the cow milk transfer reflex during machine milking are the result of exposure to the threshold force of a given value of a variable vacuum and simultaneous mechanical irritation by the teat rubber of the udder of the cow udder system. This effect leads to the discovery of sphincters with the subsequent release of the hormone oxytocin by the pituitary gland and the milk accumulation from the alveolar udder tissue. Signal environmental factors (sounds of a vacuum pump, milking machines, feeder) cause reactions in cows not only by irritation but also by frequency. It has been established that exposure to a high-frequency electromagnetic field destroys most of the common causative agents of mastitis-staphylococci, streptococci. For the treatment of mastitis, stimulation of lactation and the reflex of milk flow in cows, it is promising to apply the effect of a high frequency electromagnetic field modulated by radio frequencies, which contribute to the conversion of electromagnetic field energy into energy of nerve impulses and chemical reactions of mitochondrial cellular mechanisms of udder alveolar tissue cells. The use of alternating sets of specific frequencies of a modulating electromagnetic field of high frequency allows the alternation of “killer” frequencies for microbes with stimulating secretion of alveolar cells of the udder and with frequencies that act anti-inflammatory. It is essential to determine the frequencies that create protective inhibition from exposure to extreme irritations of milking factors (increased vacuum, durable worn nipple rubber). With prolonged exposure to an electromagnetic field, such frequencies a repeating conditioned stimulus of a weak strength, which precede and accompany the impact of the milking machine, and stimulate the activity of the nerve centers of the milk yield reflex in cows, creating a dominant lactation.

Measurements of neutron-induced cross sections to generate nuclear data are a core activity of the JRC-Directorate G Standards for Nuclear Safety, Security and Safeguards unit in Geel. Thin 10B layers are of great importance in this activity as they are used to measure the absolute neutron flux in the beam using the standard 10B(n,α)7Li reaction cross-section as a reference. After a period of reduced activity and in line with a renewed interest for nuclear data, the demand for high quality 10B targets increased. In this paper we describe the design and features of a new e-beam evaporator specifically customized for the preparation of boron targets as replacement of the old dysfunctional equipment. Several 10B targets of varying thicknesses were prepared and characterized as part of the factory acceptance tests and implementation in the JRC-Geel target preparation laboratory. Differential substitution weighing was applied for mass determination and in order to calibrate the thickness monitor. Comparative time-of-flight measurements relative to 10B and 235U standard targets were conducted at the GELINA neutron time-of-flight facility at the JRC-Geel site as second methodology for the determination of 10B areal density. The morphology of the layers was assessed by means of Scanning Electron Microscopy (SEM). The determination of impurities was realized by means of Energy Dispersive X-ray (EDX). Finally, two boron targets were prepared in the frame of the measurement of the neutron induced fission cross-section of 230Th at the n_TOF neutron time-of-flight facility at CERN.

High electronic excitations in radiation of metallic targets with swift heavy ion beams at the coulomb barrier play a dominant role in the damaging processes of some metals. The inelastic thermal spike model was developed to describe tracks in materials and is applied in this paper to some systems beams/targets employed recently in some nuclear physics experiments. Taking into account the experimental conditions and the approved electron-phonon coupling factors, the results of the calculation enable to interpret the observation of the fast deformation of some targets.

Published: February 2020

Electroporation ablation is a promising non surgical and minimally invasive technique of tumor ablation, for which no monitoring is currently available. In this paper, we present the recent advances and challenges on the numerical modeling of clinical electroporation ablation of liver tumors. In particular, we show that a nonlinear static electrical model of tissue combined with clinical imaging can give crucial information of the electric field distribution in the clinical configuration. We conclude the paper by presenting some important questions that have to be addressed for an effective impact of computational modeling in clinical practice of electroporation ablation.
