In veterinary practice, feed biologically active additives of plant and animal origin are widely used to improve digestion and absorption of nutrients, as well as to correct the normalization of metabolism. One of these biologically active drugs is denatured emulsified placenta (DEP) which has antiviral, anti-inflammatory, and immunomodulating properties. Therefore, the purpose of our research was to study the effect of DEP on the morphological composition of dog blood. During the research, it was found that the number of red blood cells in dogs of the control group was 1.57% or 0.12 x 1012/l more than in the experimental group. Erythrocytes of dogs in the control group had 0.37% more volume than the same indicator in the experimental group. However, each red blood cell of animals in the experimental groups was characterized by a high content of hemoglobin in it by 1.6%. Before the start of the experiment, the number of lymphocytes in the blood of dogs in the control and experimental groups was 4.07 and 2.34%, respectively, below the minimum reference value. The number of monocytes and granulocytes in the peripheral blood of dogs in the control group was 0.23 and 1.49% higher, respectively, than in the control group. The platelet content was higher in the control group than in the experimental group by 49.38 x 109/l or 27.3%. Changes that occur in the body of dogs under the action of a biostimulator indicate an increase in the production of antibodies to protect the body from infections and ensure the animal's immunity. They completely regulate the immune system
The urgent task facing the agro-industrial complex is the improvement of storage methods for agricultural products and the development of new ones. One of the actively cultivated crops, characterized by a variety of species, valuable taste and medicinal properties – grape. It is possible to provide the population with fresh grapes of high quality through the introduction of effective storage technologies that reduce losses, preserve marketable properties and biological value. One of the effective ways to preserve the quality of grapes during storage is the use of sulfur dioxide (SO2). This gas inhibits oxidative enzymes in berries, thereby reducing the rate of development of the phytopathogen Botrýtis cinérea, which causes gray rot. At the same time, it is especially important to control the rate of release of sulfur dioxide, since at the beginning of storage it is necessary to ensure the receipt of a large amount of it, which will eliminate Botrytis spores present on the surface of the berries and stabilize the existing damage. Further, during the entire period of storage of grapes, sulfur dioxide must be supplied in minimal quantities. Such dynamics of SO2 emission can be ensured by the use of two-phase generators of sulfur dioxide. The article investigated the effects of sulfur dioxide generators on the quality of grapes during storage. The study also investigates quality indicators of grapes of several varieties zoned in the Krasnodar region under long-term storage
The article presents the results of research on the impact of tillage technologies on the value of its density in the cultivation of winter wheat in conditions of insufficient and unstable wetting of the south of Russia. Experimental studies were carried out in the conditions of a long-term stationary experiment with a four-field crop rotation with different variants of tillage (dump, layer-by-layer, small, surface). The soil density was fixed at spring tillering of winter wheat and at the end of the growing season. Conducted analysis of variance shows that the soil has relaxation abilities, i.e. over time, it restores its properties by compaction ability, since studies conducted during the period of tillering of winter wheat show that Ffact. Ftable. (5,794,76), i.e. methods of treatment have an impact on soil compaction, which cannot be said for the case at the end of the growing season of winter wheat. The ability to restore its properties is a remarkable property of the soil, as it prevents them from over-compaction. The energy intensity of the compacted soil treatment increases to 30%, while the degree of crumbling is significantly reduced and its lumpiness increases. The most fundamental way to reduce the density of the soil is its timely loosening by working bodies of agricultural tools. Tillage methods affect soil density, the correlation coefficient between tillage methods and soil density varies between 0,929-0,979. The most radical way of soil decompression is exposure to it by a certain type of working bodies
At the Kuban Agricultural Association OJSC, Ust-Labinsky District, Krasnodar region, a research has been carried out on obtaining embryos from cows and heifers of donors using sexed and conventional frozen seed. In the first experiment, 159 doses of ordinary frozen semen from 3 different bulls were used to inseminate 57 cows and heifers - donors. In the second experiment, 63 doses of normal frozen semen from 3 different bulls were expended for insemination of 21 cows and heifers of donors after treatment with super ovulation for 9 days. On the 7th day after insemination, the embryos were collected in experimental cows and heifers of the donors, their number was counted, and the quality was evaluated. As a result of the study, it observed that the obtained embryos from each donor were different in quantity and quality. The number of embryos, using traditional sperm, was from 1 to 42, and on average per cow 13.68 ± 2.45. Among them, 8.40 ± 1.08 embryos belonged to the first class, 0.35 ± 0.45 - to the 2nd class; 4.90 ± 0.94 to the 3rd class, as well as 4.90 ± 0.94 embryos were degenerated. After donor insemination with sexed sperm, 1 to 22 embryos were obtained, an average of 9.01 ± 4.03. Including 4.92 ± 3.04 embryos belonging to the 1st class, 1.31 ± 1.02 - of the second class, 0.28 ± 0.27 - of the 3rd class and 2.48. ± 0.71 degenerated. The results showed that the average number of embryos obtained using conventional sperm is larger compared to the use of sexed semen, regardless of the donor cow or heifer.
Conclusion: the use of traditional frozen semen allows us to get more and better quality embryos from cows and heifer donors
This article is devoted to the definition of criteria for the functioning of agrocenoses. It is determined that the functioning of agrocenoses largely depends on the resource potential: used ecological zones, applied technologies, technological operations and regulations. The basis of effective reproduction and sustainability of agrocenoses is the optimal balance of resources used. The work purpose is the substantiation of optimal parameters of resource intensity of the technological processes in horticulture and the determination of the limits of sustainability of agrocenoses under anthropogenic influences. The integrated assessment of resource intensity of production and technological processes in industrial fruit growing for optimization of its parameters of resource intensity is given. The optimum of reproduction possibilities and limits of stability of agroecosystem components in comparability with the level of technogenic load is achieved by means of regulation of permissible anthropogenic loads in separate elements of agroecosystem and resource balance of elements and processes. The limits of sustainability of fruit agrocenosis under anthropogenic influences are substantiated as well. Regression dependences on technological processes in the context of certain types of resources used are established: capital (depreciation), turnover (material consumption and coefficient of consolidation) and labor (wage). The complex coefficient of efficiency of the economic mechanism of resource saving is defined. The article substantiates optimal parameters of resource-intensive production and technological processes in industrial horticulture. We have also calculated the normative value of the total index of resource intensity of technological processes
At present, the problems of blocking network traffic in computer networks, in particular, in the global Internet, are becoming increasingly topical. Understanding blocking mechanisms, opening new opportunities to circumvent such protection will give us, on the one hand, both new methods and methods of protection against unwanted blockages, and the vector of development of funds, in fact, stopping unwanted traffic, obstacles passing through network nodes. The article proposes an approach to effectively bypass access restrictions to websites based on HTTP tunneling with minimal costs, combined with the approach used in peer-to-peer networks. A description of the algorithm and its key features. A new approach has been introduced in the task of ensuring the accessibility of websites, which has several advantages and eliminates the disadvantages of existing solutions in the form of anonymous networks - the use of special node solutions and a strong dependence on the number of nodes in the anonymous network. The level of development of modern network infrastructure, the transition of society and most of human civilization to the information-network existence dictates new requirements for technical means of monitoring and analyzing network traffic. That, in turn, requires the development of new approaches to solving relevant problems
The article presents the results of studying the influence of the reproduction zone on the sowing and yield quality of seeds of wheat varieties of soft winter selection of the NPC named after P. P. Lukyanenko. From the sowing qualities regulated by the state standard of the Russian Federation, the following indicators were studied in the experiment: viability ( % ) and weight of 1000 seeds (g). The P-1 seeds obtained in the NPC were sown in different agro-climatic zones of the region in the optimal time with the same seeding rate of 250 seeds/m2. The obtained seed material was supplied for the study of sowing qualities and yielding properties of learning in the nursery ground control. The yield quality of seeds significantly differed depending on the area of their production in the previous year. According to the results of four years of research, the seeds of varieties obtained in the Northern zone of the region had higher sowing qualities compared to seeds from other agro-climatic zones. The average seed viability for four years in the Tanya variety was 97.6%, in the Yuka variety-97.7% and in the Grom variety-98.0%. The largest mass of 1000 seeds was also observed in the studied varieties from the Northern zone of the region. Consequently, a more complete realization of the potential of the three studied varieties was also observed in the Northern zone of the region

The article carries out an analysis of morpho-chemical parameters of ostrich eggs when l-carnitine is included in the diet. Studies were conducted on two groups of ostriches: I-received a standard diet, II-to the standard diet received L-carnitine at a rate of 300 mg per 1 kg of feed. From April to August we were studying the ostrich egg production, morphological composition of eggs, chemical composition of albumen and yolk, the amino acid composition of egg yolk, the level of cholesterol, fatty acids including saturated, unsaturated and polyunsaturated. It has been determined, that L-carnitine increases the egg production of ostriches by 24%. The weight of protein in the groups was 56.9-56.2%; yolk-27.6-26.7%; shell-16.4 -16.2%. The amount of cholesterol in the egg yolk of the 1st group ostriches was 12.2 mg, in the 2nd one it decreased by 7.4% (P>0.95) and amounted to 11.3 mg per gram of yolk. The level of amino acids in the egg yolk of the 1st and 2nd groups was approximately equal. The number of fatty acids in the 1st and 2nd groups was: saturated 39.5 and 39.7%, monounsaturated 49.99 and 49.80%, polyunsaturated 10.37 and 10.47% respectively. The sum of unsaturated and polyunsaturated fatty acids in ostrich eggs was 60.36 - 60.27%. The sum of ω3 and ω6 fatty acids is 10.18 and 10.25%. Ratio ω3: ω6-1: 3,3. The ratio of polyunsaturated to saturated acids was approximately 1:3, and polyunsaturated + monounsaturated to saturated-1.52 units (approximately 1.5 : 1).
We took 20 samples of centralized water for bacteriological studies at two farms of the collective farm “Limann” and the collective farm “50 years of the name of the October Revolution” of the Neklinovsky District of the Russian Federation and sent to the Rostov Regional Veterinary Laboratory. Thus, according to the results of laboratory studies of water, it was found that in the first farm in 7 samples out of 10 under No. 1, 2, 4, 5, 8, 9, 10, common coliform bacteria were found (the number of bacteria in 100 ml according to MUK 4.2. 1018-01), as well as thermo-tolerant coliform bacteria (the number of bacteria per 100 ml according to MUK 4.2.1018-01), in the second farm in 5 samples out of 10 under No. 3, 4, 5, 7, 8 common coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01), as well as thermo-tolerant coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01). According to the results of studies using the rapid test "Biocontrol" revealed that in the first farm in 2 samples out of 10 under No. 4.9 per 1 ml of bacteria 105, which indicates water pollution, and in 5 out of 10 samples No. 1, 2, 5, 8, 10 per 1 ml of bacteria 107, which indicates a strong pollution of water and is the basis for the prohibition of watering animals. In the second household, in 3 samples out of 10 under No. 4, 5, 8 per 1 ml of bacteria 105, which indicates water pollution, and in 2 out of 10 samples No. 3, 7 per 1 ml of bacteria 107, which indicates severe water pollution which is not recommended for animals. Thus, the studied water samples by the bacteriological method coincide with the “Biocontrol” rapid tests, which makes it possible to practically use it in farms
