Authors: Berezhnov Nikolay 
Published: December 2019

AbstractThe studies were carried out to determine the compliance of traction-speed performance of the tractor as part of the machine-tractor unit with aggregation requirements, taking into account the random nature of changes in external factors. The work was carried out using the example of the assembly Fendt 936 Vario + AVA-12.6 “Agropitatel” in Leninsk-Kuznetsk district of Kemerovo region in 2017. Using the control dynamometer method, the probabilistic characteristics of the traction resistance of the machine, its dependence on the speed of movement in the operations of the main tillage and intra-soil liquid fertilizer application were determined. The studies were carried out on medium humus on stubble background with depth of soil treatment and fertilizing of 21 cm and the average length of run 1100 m. The tractor Fendt 936 Vario does not ensure compliance with the requirements for operating speed and slipping of propellers when working within the range of average specific drag. Power equipment with the estimated parameters will improve the traction coefficient of performance for 4.7…13.6% in comparison with the tractor Fendt 936 Vario, which will increase the average working traction on the hook, which is implemented without violation of the established requirements. The result will be an increase in the average operating speeds of the unit and an increase of its net hourly productivity.

Authors: Samokhvalova Elena 
Published: December 2019

Abstract
The work was done in order to improve the territorial organization of agricultural production in the context of the implementation of the adaptive landscape land use strategy based on the assessment and analysis of the spatial and temporal structure of the natural agricultural potential (NAP) of the territory. The results of dynamic statistical simulation of normative crops productivity and land bonitet assessment of administrative districts of the Samara region are used. GIS analysis of the results and mesoscale comprehensive assessed zoning of the territory is applied. As a result, seven mesozones were allocated in the region with assure accordance of the bonitet scales and crop productivity formation factors (correlation coefficients with many indicators 0.7-0.9), which include relevant assessment areas with the most uniform conditions (coefficient of variation of indicators within 10%). The zoning is done in the contours of the administrative division of the territory and forms the geographic basis for resolving the agro-production issues of the respective management and land assessment objects in the framework of the formation of the adaptive landscape land use system.

Abstract
Energy saving at any enterprise is an urgent problem associated with high expences for energy carriers and a constant increase in their cost. The aim of the study is to modernize the energy system of one of the poultry factories in the Vologda Oblast in Russia in order to reduce electricity costs. Modeling methods for a comprehensive assessment of possible options were usedas well as an experiment that showed that the most effective way to reduce electricity costs was to upgrade the energy system based on “small generation” using traditional fuels. The modernization allowed the poultry farm to produce up to a third of its own electricity with the help of mini-CHPs annually, and to keep the cost of the generated kW⋅h three times lower than the network. The experience of modernization of the energy system of a poultry farm in Russia has confirmed the possibility of joint use of PTL-6(10) and a steam turbine generator at the enterprise. The paper will be useful to researchers and energy specialists who are looking for ways to save energy on a poultry farms.

Published: December 2019

Abstract
The aim of the studies based on the modeling of hybrid genotypes of spring wheat is to study collection varieties of various origin at several test sites, different in soil and climatic conditions, in order to identify the best of them with high adaptive potential. Hybrids created using the set of limiting traits of varieties distinguished in three test points were involved in the biotechnological process to obtain dihaploid forms in order to accelerate the breeding process. Based on them, a new source material has been created. Using the optimized method of haploproducer Z.mays on the basis of a hybrid combination (Visa x Amir), the new variety of spring soft wheat Lisa was created, with a yield potential of 7.5-8.0 t/ha, resistant to lodging, meeting quality requirements in terms of quality to strong wheat. The variety is recommended for cultivation in 2 (North-West), 3 (Central) and 7 (Middle Volga) regions of the Russian Federation.

Abstract
The problem of resistance of winter wheat to low negative temperatures is one of the most important in the agriculture economy, the solution of which will contribute to the increase of yield and gross grain harvesting in the Russian Federation. Therefore, the creation of winter wheat varieties capable of resisting the effects of frost during winter is very relevant. The aim of the study is to identify high frost-resistant winter wheat varieties for use in the breeding process by direct and indirect methods of assessment, and to define the possibility of using free proline content to detect genotypes resistant to low negative temperatures. The paper presents the results of complex studies on frost resistance of winter soft wheat varieties by three scientific centers: Agricultural Scientific Center Donskoi, National Grain Center named after P.P. Lukyanenko and Federal Rostov Agrarian Scientific Center. Therein is shown the possibility of using an indirect method - defining free proline content as a method of assessing frost resistance of samples. After freezing plants grown in sowing boxes at four different temperatures, varieties were identified that significantly exceeded the Tarasovskaya 29 classifier in plant safety: Polina, Volnitsa, Volny Don, Ascetic, Don Bezostaya, and Don 107. Samples that were distinguished by the safety of plants in direct evaluation methods also showed a high content of free proline in laboratory and field experiments. Correlation analysis between the values of various methods for assessing frost resistance showed their close relationship. Varieties of winter soft wheat characterized by high frost resistance, on average, accumulate more of this amino acid in the leaves in laboratory and field experiments.

Published: December 2019

Abstract
Conventionally, crop cultivation technologies are improved by developing (creating) more effective elements and implementing them in a fragmented way using a transformational approach. It has been found that a morphological approach is more promising and effective for these purposes when creating and implementing the holistic production agricultural technologies and the corresponding technological systems. For its implementation, the methods of engineering design of complex systems are proposed to be used. The presented paper outlines the main methodological issues of engineering technological design of agricultural cultivation technologies. The purpose of the research is the development of methodological provisions for the formation and selection of promising technological processes in technological modules when cultivating crops. To form options of technologies, the methods of morphological analysis are used. When selecting acceptable, promising and effective options for the designed projects, the decision-making theory methods are used. The analysis of scientific works shows that almost all the presented models have the same drawback: the lack of a mechanism for the formation and selection of promising technological processes implemented in a particular technology and so far, there is no effective methodological approach for its implementation. According to the results of scientific research, it was found that in the formation of systems of mechanization of plant growing processes, it is advisable to use the methods and techniques of engineering design of individual technological processes and technical equipment that have not been developed so far. A block hierarchical approach to the designing of crop production agricultural technologies is proposed. In the design process, the following basic principles must be maintained: a systematic approach, focus on obtaining optimal solutions, a comprehensive (multi-criteria) approach, a functional approach, iterative design process, focus on the final result, a combination of formalized and heuristic methods, the principle of open systems, the principle of modeling objects, the principle of functional completeness, etc. A general logical scheme of the process of engineering design of agricultural plant technology objects is proposed, where the main stages and design stages, design tasks and the main methods for solving them are defined.

Abstract
In order to ensure the best digestibility of feed, all the nutrients included in their composition should be given to animals in crushed form. Particle size of feed is different for all species and age categories of animals. The most common “shock” crushers give up to 30% of the dust fraction and up to 20% of the underground one. Nowadays, impact and centrifugal-rotor grain crushers that use a “slice-chipping” are the most effective ones. The small-sized horizontal impact crusher, which constructive and technological scheme of grinding is fixed in the patents of the Russian Federation, was made for carrying out experiments. The quality of the grinding process was assessed by three different indicators (the degree of grinding, the grinding module and the actual effectiveness of the process). Data on joint and separate grinding of wheat, barley, oats and corn were obtained. The conducted multifactorial experiment showed that the proposed design of the impact crusher allows obtaining up to 98% of the finished product balanced by the particle size at specific energy costs up to 2 WH/kg and productivity up to 260 kg/h. The most rational design and operating parameters of the horizontal impact crusher for various types of grinding were established on the basis of existing standards, zootechnical requirements and the latest scientific research. The developed horizontal impact crusher can be used instead of the widely used small-sized hammer mills, since, in comparison with them, its specific energy consumption is reduced to 50%.

Abstract
The aim of the paper was to study the activity of nucleolar organizer zones of blood lymphocytes of Stavropol breed sheep in postnatal ontogenesis and during pregnancy. Blood smears for cytomorphology studies were painted with silver nitrate and subsequent additional coloring with azure and eosin. By measuring the parameters of the nucleus and parameters of the activity of nucleolar organizers (AgNORs), the changes in the morphofunctional state of the protein-synthesizing apparatus of blood lymphocytes in sheep of Stavropol breed in postnatal ontogenesis were evaluated. It was found that newborn lambs’ area of the nuclei of lymphocytes was 76.50 ± 2.30 µm2. By the age of three months, the area of lymphocyte nuclei in sheep significantly increased by 6.08% and amounted to 81.46 ± 2.45 µm2, and did not change significantly until the age of twelve months. The number of units of argentophilic nucleolar organizers in the nuclei of lymphocytes (AgNORs) is from 1 to 4. The average area of AgNORs in the nuclei of lymphocytes is in the range from 73.60 ± 2.45 up to 80.10 ± 2.41 µm2. In sheep of Stavropol breed on the 90th day of pregnancy, the area of the nucleus of lymphocytes was 68.70 ± 2.15 µm2. By 135 days of pregnancy, a significant decrease in the area of the nuclei of the lymphocytes by 14.66% was found. After childbirth, there was a slight decrease in the area of lymphocytes in sheep compared to the previous period of research. During pregnancy, sheep were found to have from 1 to 3 AgNORs with a total area from 0.70 ± 0.11 to 2.93 ± 0.43 µm2. On the basis of the conducted studies, it can be concluded that in postnatal ontogenesis and during pregnancy of sheep, the functional state of lymphocytes changes, this is manifested in changing the parameters of the area of their nuclei, the number and total area of AgNORs.

Abstract
The aim of the research was to study pathomorphological changes in the testicles of goats in acute anaplasmosis. Diagnosis of anaplasmosis in sick goats was carried out taking into account the characteristic clinical signs and studies of peripheral blood smears. Blood smears after fixation in alcohol ether were stained according to Romanovsky-Giemsa by hematoxilin and eosin. For histological examination, pieces of testicles and appendages of testicles of 0.5 cm thick were selected, which were fixed in an 8% neutral aqueous solution of formalin. The resulting material was poured into paraffin according to the generally accepted method. Histological sections of 5-8 microns thick were made from the obtained paraffin blocks and stained with hematoxilin and eosin using the method of Van Gieson and Mallory. Micro photos were made with a series of rendered images on the basis of Olimpus 2000. The study revealed the following changes: the spermatogenic epithelium has desquamation, in the lumen of the convoluted seminiferous, there were tubules protein detritus, exfoliated cells of seminiferous epithelium and macrophages. Sertolli cells were in a state of vacuole dystrophy and necrosis. In the interstitial tissue around arterial vessels and convoluted seminiferous tubules, focal accumulation of lymphoid-macrophage infiltration was found. Endocrine cells located in the interstitial were in a state of vacuole dystrophy and necrosis. Thus, in goats older than 6 months with acute anaplasmosis in the testicles, pathomorphological changes are characteristic of acute parenchymal orchitis.

Abstract
The aim of the research was to study the dynamics of thyroid hormones and thyroid-stimulating hormone of the pituitary gland in Stavropol breed sheep in postnatal ontogenesis and the establishment of thyroid status in animals before insemination, during pregnancy and after childbirth. Determination of concentration of total triiodothyronine, free thyroxine and thyroid stimulating hormone in serum was performed by solid-phase enzyme immunoassay (ELISA) using standard test systems. As a result of the studies, the level of thyroid hormones and thyroid-stimulating hormone in the blood of sheep of Stavropol breed in postnatal ontogenesis was determined. It was established that at the birth of lambs, the lowest level of triiodothyronine (2.55 ± 0.04 nmol/l), thyroxine (19.47 ± 0.45 pmol/l) and thyrotropic (0.31 ± 0.05 Mme/ml) hormone was observed in the blood, compared with other age periods. By the age of three months, the levels of triiodothyronine and thyroxine increased significantly by 7.7% and 24.8%, respectively. When comparing the data in six monthly young ewes, the concentration of all studied hormones was the highest in comparison with other age groups (triiodothyronine – 3.11 ± 0.21 nmol/l; thyroxine – 26.29 ± 0.97 pmol/l; thyrotropic hormone – 0.81 ± 0.09 Mme/ml). In the age of nine months, a significant decrease in triiodothyronine by 16.8%, thyroxine - by 13.2% and thyroid-stimulating hormone - by 34.6% was observed, compared with ewes of 6 month old. By the age of 12 months, only free thyroxine was significantly changed, its serum concentration increased by 9.5% and amounted to 25.21 ± 0.31 pmol/l, compared with the data of nine-month-old sheep. It was found that the concentration of triiodothyronine changes significantly in sheep after childbirth and is 2.53 ± 0.03 nmol/l, which is 6.3% more than in pregnant ewes. The level of thyroxine on the 90th day of pregnancy decreases by 5.3%, and by the 135th day by 16%, compared with the previous period of the study. Thyroid-stimulating hormone in the blood serum of sheep on the 90th day of pregnancy becomes significantly lower by 29% (p ⩽ 0.05) than its concentration in non-pregnant ones. After childbirth, thyroid-stimulating hormone significantly increased by 26.66% (p ⩽ 0.05). As a result of the studies, in sheep of Stavropol breed, standard sizes of the level of thyroid gland hormones (triiodothyronine, thyroxine) and thyroid-stimulating hormone were established.

Abstract
In this work, the clinical significance of changes in the activity of adenosine deaminase (ADA) and the content of polyamines in the blood plasma of cats with breast cancer was studied. There were examined 30 cats aged 1 to 20 years, operated on in veterinary clinics due to spontaneous neoplasms. Histological studies of surgical material were performed to establish nosological forms of the tumor. The results of the measurements showed that there were no significant differences between ADA activity in the blood plasma of cats diagnosed with invasive non-specific carcinoma and ADA activity in the blood of healthy animals. In the plasma of animals diagnosed with fibroadenomatous breast hyperplasia, ADA activity was reduced by 35% compared with the control group. The content of putrescine in the red blood cells of cats with benign neoplasms of the mammary gland (fibroepithelial hyperplasia) was statistically significantly increased 5 times compared with the control group. In malignant neoplasms of the mammary gland (invasive non-specific carcinoma, tubular cancer and fibrosarcoma), the content of putrescine and spermine in the blood significantly exceeded the control values by 60 and 10 times, respectively, compared with the control group. Thus, the data obtained indicate the possibility of using polyamines in order to improve the accuracy of diagnosis and treatment of cats with breast cancer. The determination of ADA activity in the blood plasma of cats with breast tumors in the early stages of cancer is not an informationally significant indicator as a tumor biomarker.

Published: December 2019

Abstract
The paper considers solutions for producing functional food based on products of infra-red drying obtained with the use of original compact multilevel closet facilities designed to be applied at agricultural enterprises. These facilities originate thermal impulses influencing raw materials by means of controlled infrared radiation emitted by high-temperature linear incandescent lamps and reflected in mirrored surfaces. The facilities ensure effective dehumidification and high-grade preservation of biologically-active agents contented in raw materials. This is due to smooth uniform evaporation of moisture from the material within the entire volume of the facilities, management of heat regime through direct control of material temperature and minimization of material’s contact with atmospheric air during drying. The condition of biologically-active agents in various agricultural products was estimated: raspberry, dewberry, drained white and red grapes. The paper gives organoleptic estimate of alcohol-free beverages with advanced biological value based on infra-redly dried products.
