Abstract
The key problem of modern farming is the search for an alternative to traditional arable farming, which leads to a permanent decline in soil fertility, primarily to a decrease in organic matter and significant loss of moisture. The study was aimed at studying the effect of waste and zero tillage on the agro-physical indicators of the soil, yield, sugar accumulation dynamics and the economic efficiency of cultivation of a sugar sorghum hybrid Slavic homestead. The experience was conducted in Commercial Farmers Association “Kuznetsovskaya”, Ilovlinsky District of the Volgograd Region, on zonal subtypes of light chestnut soils in the period from 2009 to 2015. Research methods were used according to generally accepted methods and recommendations. When considering the effect of treatments on soil density, there was an increase in soil compaction due to zero tillage. When determining the state of aggregation of soil by zero tillage, the number of valuable aggregates was 69.43 % versus 65.43 % for land tillage. The coefficient of structure was zero tillage. The yield of sugar sorghum amounted to 54.7 t/ha, which showed an increase of 7 % relative to dump soil treatment. The zero tillage profitability ratio was 104 %. The transition to zero processing will provide increased productivity, reduce the need for labor and technology, reduce the time for field work, make it more optimal, increase the income of agricultural enterprises, increase the wages of workers and improve their social conditions, which is an important economic and social advantage of resource-saving technology.

Abstract
One of the urgent problems of reducing crop yields is the unsatisfactory phytosanitary condition of the fields, leading to economic losses in agriculture, especially when switching to resource-saving technologies [1, 2]. The aim of the work is to study the phytosanitary condition of agrocenoses depending on the method of tillage. For this, plots were laid in the Orenburg district of the Orenburg region. As a result of the experiments carried out with various processing methods, it was noticed that in experiments with small loosening, the amount of weed-field vegetation increased by 2 times, for example, FPV (phenoceptic threshold of harmfulness) of Panicum miliaceum L. was exceeded by 36 times, revealed a change in life forms towards xerophytic flora. On the same experimental plots conducted a study on the presence of root rot. In the experiment with deep tillage (plowing) of spring wheat, 46% of the plants affected by Fusarium rot were observed, and 50% of the plants affected by the pathogen were counted on the experience in tillage.

Abstract
The significance of rumen for the body of ruminants determines the prospects for improving the efficiency of ruminal digestion, which can be achieved through the use of probiotics, antimicrobial metabolites and other drugs. Recently, plant extracts of medicinal plants have been actively used, for example, oak bark extract (Quercus cortex). Based on the results of recent studies, antiquorum substances are one of extract components. According to the results of in vitro study, it was established that addition of oak bark extract (OBE) in various concentrations into ruminal fluid (RF) affects enzymatic activity and is accompanied by a change in feed digestibility from 2.42% (P <0.05) to 7.13% (P <0.01). The greatest digestibility is achieved after the introduction of OBE in a dosage of 3.3 mg/ml. The use of EKD leads to an increase in the pH of the ruminal fluid to 6.7-6.8 and stimulation of enzymatic activity of microorganisms, therefore, leads to an increase in digestibility and absorption of nutrients.

Abstract
The purpose of this study was to identify the characteristics of the redistribution of chemical elements in various biosubstrates when modeling thyrotoxicosis and hypothyroidism in animals. Male Wistar rats were the object of the study. Animals of the first experimental group were intraperitoneally injected with L-thyroxine to simulate the state of experimental thyrotoxicosis. Animals of the second experimental group were injected merkazolila to simulate the status of experimental hypothyroidism. The third group was the control group. The obtained data demonstrated the effect of thyroid status on mineral metabolism. The greatest changes in the elemental status were found in the thyroid gland: a high content was found in hypothyroidism Cr (p<0,05), V (p<0,05), Co, Fe, As, Ni, Mn, Se, Zn and lower values I (p<0,05) and Si (p<0,05); with hyperthyroidism – a higher content of Co (p<0,01), Ni (p<0,05), Cu (p<0,05), Zn (p<0,05), Cr (p<0,05), Li, V, Mn and lower content of Si (p<0,05). When comparing the experimental groups, statistically significant differences were revealed: hyperthyroidism was accompanied by accumulation of Cu, Zn, I in the thyroid gland; hypothyroidism - As, Se and V. Statistically significant lower values of Cr, Cu, Ni, Se, Si, V, Zn and a tendency to lower As, I, Fe and Mn values were recorded in the bone tissue of animals from the experimental group I, in animals of experimental group II a higher content of almost all the studied microelements was observed, however, statistically significant differences were obtained only in terms of As (p<0.05) and Ni (p<0.05). In the hair of animals, when modeling hyperthyroidism and hypothyroidism, higher values of Fe, Se, Si, V, Cr were observed as compared to the control.

Abstract
Akhal-Teke is the ancient cultural horse breed of oriental origin. The study of genetic features different subpopulations of Akhal-Teke breed was carried out on 17 loci of DNA microsatellites (VHL20, HTG4, AHT4, HMS7, HTG6, AHT5, HMS6, ASB23, ASB2, HTG10, HTG7, HMS3, HMS2, ASB17, LEX3, HMS1 and CA425) to assess their genetic differentiation. The results of DNA typing of 5457 Akhal-Teke horses on 17 microsatellite loci show that gene pool of world population is represented by 121 alleles, among which 98 are found in all countries. Comparative analysis of genotypes of horses representing different subpopulations indicates that they differ in the number of alleles (100-117), allele frequencies, the level of polymorphism Ae (3.40-3.91) and the degree of observed heterozygosity Ho (0.661-0.724). The genetic distances between the subpopulations varied in range from 0.007 (Russia – CIS) to 0.051 (Czechia – Turkmenistan). Correspondence to HWE was maintained in all countries, which confirms the negative value Fis. Genetic options of the Akhal-Teke by index Fst varied in a range 0.001 -0.078 at the mean value Fst=0.022. Cluster analysis demonstrated more close relationship between Russian, CIS and European subpopulations.

Published: November 2019

Abstract
It is known that the use of native fats for feeding ruminants causes an inhibitory effect on the rumen microflora. One of the problems with the use of fats protected by various technologies is a change in the composition of the rumen microflora. It is necessary to improve existing and create new types of protected fats.
The research object was 12 red steppe calves divided by three groups - the control one and two experimental ones (n = 3). The animals of experimental group I were fed with a Palmatriks fatcontaining supplement at a dose of 0.4 kg/head, and the animals of group II - an experimental supplement (ES) at a dose of 0.25 kg/head.
The use of Palmatrix contributed to the growth of Firmicutes microorganisms (1.74%), Candidatus Saccharibacteria (by 4.5%), Actinobacteria (by 1.83%) and reduced the number of Bacteroidetes bacteria (5.19%), Verrucomicrobia (by 0.75%). Feeding pf group II with ES increased the number of Saccharibacteriageneraincertaesedis bacteria (by 14.77%) in comparison with experimental group I. The combination of fat supplements with components reduced the number of Bacilli, Negativicutes and Bacteroidia bacteria by 14.77%, 9.54 and 8.12%, respectively.

Abstract
The study covers bull-calves of the Kalmyk breed (n=182) aged 12-14 months. It considers the impact of polymorphism of the growth differentiation factor 5 (T586C in exon 1) ensuring development, maintenance and restoration of bones and cartilage on body parameters, body weight and musculoskeletal diseases. The frequency of occurrence of TT alleles in selection made 48.9%, TC – 46.7 and CC – 4.4%, χ2 test – 4.94. Bull-calves with CC genotype surpassed their analogues with TT and TC genotypes in terms of growth intensity and body measurements. The analysis of non-contagious musculoskeletal diseases (arthritides, bursitides, arthrobursitides) since birth until the 12th month of age revealed diseases among 17 heads (19.1%) with TT genotype, 9 heads (10.6%) with TC genotype and absence of diseases with CC genotype. There is a need for further study with increasing the group of animals with C homozygous genotype.

Abstract
The aim of this research is to assess the varieties of winter camelina in terms of productivity and adaptability in a contrast agroclimatic environment of the Middle Volga region and the region of steppe Crimea in 2016–2018. The climate of the Middle Volga region is moderately continental. The precipitation varies from 350 to 750 mm a year. The average year temperature is 5.3 °C. The climate of the steppe Crimea region is continental. The average year temperature here is 15.1 °C and the precipitation varies between 350 and 450 mm a year. In average the yield of different camelina varieties fluctuated between 1.59 and 1.83 t/ha, depending on the environment condition index (Ii -0.19–0.46). In the Penza region, the Kozir and Baron varieties gave the biggest yield with the productivity of crops equal to 1.80 and 1.83 t/ha respectively. In Crimea, the biggest yield was given by the Dikiy variety (1.74 t/ha). The variability of productivity is low at 7.4–10.1% and medium at 11.5–13.2%. The Baron variety has a low variation factor (7.4 and 11.5%) regardless of a cultivation region. All varieties had high stability which was 1.20–1.25 and 1.30–1.46 depending on a region. The Baron and Kozir varieties had the highest stability reaching 1.46 and 1.25 respectively. All varieties had a high index of stability for this crop, equal to 0.50–0.59. Camelina is tolerant of all stress factors and forms a stable yield in different cultivation conditions. All varieties showed a great ecological adaptivity and flexibility with the bi values equal to 1 and varying between 0.92–1.07. The most stable and flexible variety in the case of the Penza region is Baron (bi=0.92; σdr2=0.07) while in the region of Crimea it is Kozir (bi=0.99; σdr2=0.07). The Dikiy variety has high adaptivity parameters in both regions (bi=0.93–0.97; σdr2=0.06). The variance analysis showed that the share of “variety” factor influence is from 38.4% (the Penza region) to 39.2% (Crimea). In the variety-region relationship the influence of a variety is 40.6%. The share of “years” factor influence is 21.7–24.6%, depending on a region.

Published: November 2019

Abstract
The prediction method of the variants of annual field work complexes provides justification for machine and tractor fleet structure. It gives a graphical view of the load of power machines, evaluation and selection of mechanization equipment for a particular job or complex of works, taking into account the condition that the cost of equipment should be covered by a decreased number of employed operators and harvest losses. The authors propose an algorithm for the implementation of this method, which has led to the creation of a program Agro. A simulation is carried out using the example of a model agricultural organization. The authors confirm the inverse relationship between increasing the power capacity of tractors and the need for machinery.

Published: November 2019

Abstract
Currently, various types of robotic systems are used to collect primary data. For example, UAVs can be used to collect various types of melon required for analyzing the effectiveness of agricultural operations and predicting the yield of certain types of crops. The problem of the transfer of information accumulated by the UAV, its analysis and making management decisions remains an urgent task. As a rule, wireless sensor networks are used to transfer data to a UAV, the main problem of which is the low bandwidth of the channel. To improve the efficiency of data transmission over low-speed communication channels and the subsequent processing of the information flows of the UAVs, it is necessary to develop traffic routing methods. As part of the study, an approach has been developed that allows taking into account not only the state of the communication channel at the current time but also to predict its characteristics ahead of time.

Abstract
Cell technology can bring veterinary medicine to a new level of development. Despite the success of modern veterinary medicine, this area is understudied having enormous opportunities and unexpected dangers. This article provides experimental data on the effect of the biologically active preparation “FPB” on laboratory animals, artificially created models of the inflammatory process. We took into account the effect of placental preparation on rat embryogenesis and embryo developmental abnormalities, since the ultimate goal of this preparation is treatment of the obstetric-gynecological pathology in dairy cows. The studies have shown that the use of drugs based on the fetoplacental complex (10%-30%) stimulates reparative and regenerative skin properties. The local irritant effect of 10% and 30% drug on the mucous eye membrane and skin of rats upon was not pronounced. In a series of experiments on reparative properties of the drug, burns caused skin hyperemia with marked exudation on the skin surface. On the sixth day of the study, the area of the burn decreased by 5.8% in the first group, by 7.7.% in the second group, and by 2.4% in the control group. On the 15th day, the blisters became crusted, in 65.0% of the animals, their rejection was observed. The area of the wound decreased by 68.0%, while in the the control group, it decreased by 31.8%. The biologically active placental preparation did not have mutagenic and embryotoxic effects during the critical periods of embryo development.
