Presently, the use of plant components with antimicrobial, antiviral, antioxidant, anti-inflammatory, hepatoprotective and immunomodulatory effects is of particular interest for the preparation of biologically active additives in animal husbandry. Of great biological value as components of herbal supplements are Japanese kelp (Laminaria japonica) and spotted milk thistle (Silybum marianum (L). Gaertn), a wide range of biological action of which is due to the rich chemical composition. The uniqueness of spotted milk thistle lies in the content of silymarin − flavolignan with pronounced hepatoprotective properties, used throughout the world for the manufacture of medicines with a pronounced hepatoprotective effect. Another feature of milk thistle is its rich macro- and microelement composition, which, among other things, includes such a rare essential element as selenium (22.90 mg per 1 g of seeds), the deficiency of which in food and feed leads to the development of endemic microelementoses in humans and animals. The biological feature of Japanese laminaria is the presence in its composition of alginic acid, its salts, mannitol, laminarin and fucoidan, which have immunomodulating, antimicrobial, antacid, antiallergic and hemostatic activity, as well as a large number of minerals (26.6-32.9 % by weight of dry matter) and vitamins. Laminaria japonica thallus are rich in organic iodine, the content of which in the extracts amounts to 5.4 mg/g, which is important in the conditions of iodine deficiency, which is present at the most territory of Russia and the world. At the same time, the problem of the use of these plants as dietary supplements for animals is still under study. There is very little data on the effect of each plant on the productivity of farm animals and the quality of their products, and no information about their joint use has been obtained yet.

In various soil and climatic conditions of the Udmurt Republic, according to yield data (2016-2018) of state variety testing plots (GSU), ecological plasticity, stress resistance, genetic flexibility of 10 zoned and new varieties of winter wheat (standard - Volzhskaya K) were evaluated. The soil of the state variety testing sites: soddy-telopodzol sandy loamy - Uvinsky state varietal test site; light-gray forest heavy loamy - Sarapulsky state varietal test site; sod-mid-podzolic medium loamy - Mozhginsky state varietal test site. The agrometeorological conditions of the growing seasons differed in terms of heat and moisture supply: 2016 - hot and dry (hydrothermic coefficient – 0.70), 2017 - excessively humid (hydrothermic coefficient – 2.14), 2018 - wet (hydrothermic coefficient – 1.21). A high yield of winter wheat varieties was revealed in the southern zone of the Udmurt Republic (Sarapulskiy GSU - 3.32 t/ha and Mozhginskiy GSU - 2.95 t/ha). Weather conditions of the year mostly influenced the formation of winter wheat yield - 64.8-98.5 %. The share of participation of the variety is 0.8-31.7 %. A relatively high (3.40-3.47 t/ha) "genetic flexibility" of varieties Darina, Mera and Kazanskaya 285 was revealed, 7-9 % higher than the Volzhskaya K standard. The highest level of environmental sustainability was established in the varieties Volzhskaya K and Mera ‒ d = 67.36-67.44 %. According to the indicators of plasticity, a strong response to changes in environmental conditions was revealed in Darina, Mera, Universiada varieties (bi = 1.05-1.09); weak reaction – in Biryuza and Ilot varieties (bi = 0.91-0.92); plastic varieties - Volzhskaya K, Bashkirskaya 10, Italmas, Kazanskaya 285 and Moskovskaya 39 (bi = 0.96-1.01). The smallest gap between the maximum and the minimum yield (stress resistance) was noted for the Ilot variety ‒ 2.91 t/ha.

The current trend of winter rye breeding for the conditions of northern agriculture is development of aluminum and acid-tolerant cultivars. Studies were carried out in the central zone of the Kirov region in 1991-2019. The complex natural provocative background was used (aluminum ion content 25.5-26.7 mg/100 g of soil at a pH of salt extract 3.6-3.8; annual epiphytotic development of pink snow mold Microdochium nivale (Fr.). Winter-resistant and adaptive cv. Kirovskaya 89 served as the initial material. A rigid natural provocative background made it possible to select the best plants (500 pieces) that were transplanted in spring to an isolated area. Subsequent negative selections, field and laboratory assessments made it possible to create the Kiprez population. During the period of 1995-2013 population reproduction was carried out on a provocative background and 5 cycles of negative selection with simultaneous study in competitive varietal testing on two soil backgrounds. The first selection cycle contributed to an increase in the yield of the new population under conditions of edaphic stress over the original cv. Kirovskaya 89 by 12.6%; the second and third by 19.5 and 29.3%, respectively. Further selection did not show a significant effect. Since 2010, the further improvement of the cv. Kiprez has been carried out using individual-family selection and paired crosses. A multi-year competitive test (2014-2019) showed the advantage of the cv. Kiprez over the standard and the initial cultivar. The average yield increase to the Kirovskaya 89 variety under conditions of slightly acidic soils (pH − 5.3-5.7; Al3+ − 5.0-6.5) was 0.50 t / ha (Kirov) and 0.75 t/ha (Falenki); in the conditions of edaphic stress − 1.91 t / ha (Falenki). A combination of aluminum- and acid tolerance of the cultivar with drought resistance was revealed. In 2014, with a moisture deficit (31% of the norm) in the grain filling and ripening phase, cv. Kiprez exceeded significantly the cv. Falenskaya 4 (standard) by 0.82 tons/ha (19.1%) in a acidic background; initial cv. Kirovskaya 89 - by 1.97 tons/ha (62.7%). Cv. Kiprez is recommended for cultivation on low-fertile soils in harsh hydrothermal conditions of northern agriculture.

During the period from 2012 to 2019 in the conditions of the Kirov region there were some studies aimed at investigating the influence of hydrothermal factors (temperature, precipitation) on the duration of pea growth season, yield and constituent elements of yield productivity. The study objects were 3 pea varieties of different morphotypes bred by the Falenki Breeding Station (Falenskiy yubileynyy, Ryabchik, Falenskiy usatyy). The weather conditions during the research were contrasting in temperature regime and the amount of precipitation. The most favourable conditions for pea growth season were in 2014 and 2015, adverse conditions were in 2013, 2016 and 2018. The correlation analysis was undertaken to study the influence of weather conditions on the duration of the growth and interphase periods, yield and indicators of productivity elements of peas. It has been established that the duration of the growth season was largely influenced by the moisture regime (r = 0.71…0.76), the influence of the temperature regime was not significant. The highest grain yield of all varieties was obtained in 2014 (5.5…6.4 t/ha), the lowest in 2013 (1.9…2.3 t/ha) and in 2018 (1.3…2.5 t/ha). There was a close correlation dependence of the yield and the duration of the "flowering-ripening" period (r = 0.77…0.86) and the growth season in general (r = 0.72…0.87). Precipitation during the growth season influenced mostly on the yield of the Falenskiy yubileynyy (r = 0.70), Ryabchik and Falenskiy usatyy varieties had no significant correlation dependence between these characteristics. Hydrothermal conditions did not have significant effect on the productivity elements formation (except the mass of 1000 seeds). The significant influence on the yield formation of the Falenskiy yubileynyy variety was made by the number of rich pasture joints (r = 0.86), number of beans (r =0.88), number of grains (r =0.94) and the mass of seeds per plant (r = 0.85).

The tendency to increase crop acreage of oil flax requires the development of new varieties with high indicators of ecological plasticity, productivity and resistance to biotic and abiotic stresses. The application of modern biotechnolog ical approaches based on the use of molecular markers can accelerate the assessment of genetic differences and the dete rmination of potential of the source material for breeding. The research was aimed at assessment of the genotyping parameters of some oil flax varieties of VNIIMK breeding using the system of microsatellite markers. Seventeen variety samples of flax were used as the material for the research. DNA was isolated using CTAB buffer. Eleven SSR loci were used for the identification of varieties. Ten polymorphic loci were identified during the research. The total number of counted alleles is 32. The size of alleles varied in the range of 111-210 bps. The number of alleles per locus ranged from 2 to 6 with an average value of 3.20. The value of the index of polymorphic information content (PIC) was from 0.29 to 0.75 with an average parameter value of 0.51. The effective number of alleles for different loci is determined in the range of 1.40-3.94 with an average value of 2.28. The level of information content of the marker system (PIC 0.51) corresponds to that for identifying sets of genotypes from collections with a limitation in geographical origin. There were established differences in the frequency of occurrence of alleles. The discriminatory potential of the used marker system allowed to identify 15 variety samples. Two genotypes with common origin were identical. The degree of genetic relatedness of the studied flax genotypes has been evaluated. The obtained results will serve as the basis for the subsequent construction of genetic passports of oil flax varieties of VNIIMK breeding.

Currently, shallot (Allium ascalonicum L.) is a popular crop, it requires study and development of new varieties. Above all, it needs industrial production technology. The article presents the results of 2015-2019 research on the cultivation of salad shallot by transplanting method in the conditions of the Kirov region (North-East of the European part of Russia). It has been established that growing the Istobensky variety through seedlings allows to get a full-fledged marketable bulb during the growing season. To obtain full-fledged seedlings the seeds are to be sown on the first days of April. The optimal age of seedlings from germination to planting into open ground is 40 days. Depending on the variant, from 1 to 5 pieces of plants were grown in each cell. The control variant had one plant. During artificial illumination, LED lamps with light intensity of 5000-7000 lm were used. The recommended growing period was 20-25 days; the illumination period - 14 hours. Seedlings were grown in a polycarbonate greenhouse during 18-20 days, followed by planting into the open ground. The maximum yield with minimum cost of seeds was obtained by growing three plants in one cell. When grown by the transplanting method, the maximum bulb size of 400 g was obtained in 2016. The studies proved that the maximum yield of 5.8 kg/m2 (+1.6 to the control at LSD05 = 0.7) was obtained when sowing seeds on April, 4. Planting two plants into a hole reduced the average bulb weight by 33%, three – 40; four – 57; and five – 68% compared with the control. The study have shown that shallot of the Istobensky variety is suitable for the transplanting method of growing bulbs from seeds. During one growing period it is possible to get full-fledged bulbs of salad use with an average weight of 100-131 g, with a dry matter content of 2.99%, ascorbic acid – 13.99%, acidity – 0.61%.

The article presents the results of eight-year (2012-2019) field research on the formation of the production process of multicomponent legume and cereal grass stands while simulating pasture use. The comparison study was carried out with the use of basic grass mixtures: meadow clover (Trifolium pratense) VIK 7 + creeping clover (Trifolium repens) VIK 70 + timothy grass (Phleum pretense L.) VIK 9 + meadow fescue (Festuca pratensis) Sakharovskaya. Studied were agrophytocenoses with the use of pasture ryegrass (Lolium perenne) VIK 66 and festulolium VIK 90. As legume components, alfalfa changeable (Medicago varia) Nakhodka, birds-foot trefoil (Lotus corniculatus) Solnyshko and creeping clover VIK 70 were used. To increase the period of use, red fescue (Festuca rubra) Sigma, having the ability to regenerate itself was included into the composition of some mixtures. It has been established that alfalfa changeable, birds-foot trefoil and red fescue are the most adaptive to the conditions of drained lands. The analysis of the results of the study of the botanical composition of grass stands showed that over 8 years of growth, cereal grasses decreased their participation in the composition of herbage from 32.0-47.8 % to 1.8-22.3 % (excluding grass stands with red fescue). Four-component grass stands based on pasture ryegrass and festulolium with the use of timothy grass proved to be the most resistant to preserving sown grass species (46.3-63.7 %) and to weed infestation. Introducing additional legume species (alfalfa changeable and birds-foot trefoil) into the herbal mixture increased the period of use and significantly raised the yield of green mass of grass stands. The highest yield of green mass was obtained by herbage with alfalfa changeable and birds-foot trefoil - 23.7-26.4 t / ha, which in the seventh year of use exceeded the base grass mixture by 3.2-6.5 t / ha or 13.5-24.6 %. The results of fodder evaluation of legume-cereal ryegrass and festulolium grass stands, which denote the high-quality green fodder in conditions of drained soils of the Upper Volga Region, are presented.

The studies were carried out in 2018-2019 in the conditions of the Kirov region on sod-podzolic middle loam soil formed on the eluvia of Perm clays. The range of fertilizer doses in the long-term stationary experiment varied from 30 to 150 kg a.i. (active ingredient). With increase in fertilizer doses, the yield of winter rye of Grafinya variety grew from 3.44 t/ha at the dose of P₆₀K₆₀ to 5.94 t/ha at the dose of N₁₅₀P₁₅₀K₁₅₀. Significant addition of grain yield was obtained in all variants except P₆₀, K₆₀ and K₁₂₀. Maximum addition of grain yield to the control without fertilizers were obtained in variants with application of 120 and 150 kg a.i. /ha NPK − 3.87-4.11 t/ha (LSD₀₅ = 1.2 t/ha). In 2019 the yield of rye varied from 2.65 t/ha in the control variant to 7.08 t/ha by application of a maximum dose of N₁₅₀P₁₅₀K₁₅₀. In 2018 it varied from 1.01 t/ha to 4.81 t/ha, respectively, which was 1.5-2.6 times less, as during the period of grain formation that year the amount of precipitation was 135% from the norm. The highest payback of 1 kg a.i. of mineral fertilizers was obtained by application of ammonium nitrate N₆₀ −42.5 kg of grain. Test weight of grain was significantly higher under favorable growing conditions of 2019 and varied from 696 to 728 g/l. With the increase in doses of mineral fertilizers, there was a tendency to decrease the test weight of grain. The 1000-grain mass of winter rye did not depend on the use of fertilizers and was in the range of 28-33 grams. The content of raw protein in the grain grew with increasing doses of fertilizers, but mainly the grain of the third class of quality with the protein content of 88.1 to 110 g/kg was obtained. Bakery qualities depended on the conditions of moisture supply during grain maturation: in 2018 grain of the second and third commodity classes was obtained, in 2019 – that of the fourth class. If full fertilizer was applicated in the dose N₃₀Р₃₀К₃₀, prime cost of 1 ton of grain was 3.663 rubles with a total profitability of 91.1 %. Application of ammonium nitrate alone in the dose of N₆₀ provided profitability of 156.2 %.

The research was conducted in 2018-2019 in the conditions of the Republic of Mari El on sod-podzolic soil. Studied was the response of five varieties of spring triticale to the basal application of mineral fertilizers N₆₀P₆₀K₆₀ and nitrogen fertilization N₃₀ in the tillering phase. In 2018, grain productivity of the Rovnya (standard), Saur and Dobroe varieties (3.80-4.07 t/ha) was significantly lower than that of the Hajkar and Zaozerie varieties (4.31-4.81 t/ha). The application of N₃₀ in the tillering phase against the background without mineral fertilizers for pre-sowing cultivation provided a significant increase in yield of the varieties Hajkar (0.67 t/ha, or +15%), Dobroe (0.68 t/ha, or +17%) and Saur (0.77 t/ha, or +20%). The payback of mineral fertilizers used for pre-sowing cultivation with the increase in grain yield was not high (3.7-7.7 kg). The application of nitrogen top dressing on the background without the use of mineral fertilizers for pre-sowing cultivation was effective: Hajkar, Saur and Dobroe varieties provided a payback of 22-25 kg of grain per 1 kg of fertilizers. In unfavorable arid agro-climatic conditions of 2019, the yield of the studied varieties decreased to 2.17-3.84 t/ha, but was significantly higher by 0.4-1.0 t/ha of the control variety Rovnya. The yield increase from nitrogen fertilization was less substantial and achieved reliable values (LSD₀₅ = 0.25 t/ha) in standard Rovnya variety (on the N₀P₀K₀ and N₆₀P₆₀K₆₀ backgrounds) − 0.35 and 0.51 t/ha, respectively, Dobroe variety (on the N₀P₀K₀ background) - 0.39 t/ha and Hajkar variety (on the N60P₆₀K₆₀ background) – 0.44 t/ha. The basal application of N₆₀P₆₀K₆₀ for pre-sowing cultivation allowed to increase significantly the production of feed grain in comparison with the non-fertilized background: by 0.42 t/ha in Rovnya standard, by 0.42 t/ha in Saur variety, by 0.94 t/ha in Dobroe variety, by 0.32 t/ha in Hajkar variety, by 0.34 t/ha in Zaozerie variety. The protein content in triticale grain was the highest in the variants with the basal application of fertilizers and nitrogen fertilization (13.9-15.8 %.). Dobroe variety showed the greatest response to the application of mineral fertilizers during both years of research.

The research was conducted in the Nizhny Novgorod region in 2019 on light gray forest soil in the pea-oat crop rotation link. Studied was the effect of soil tillage systems (traditional mouldboard tillage with mouldboard plow; non- mouldboard "deep" tillage with boardless plow; non-mouldboard surface tillage with a Pottinger Synkro 5030 K chisel cultivator; minimal tillage with a disc harrow Discover XM 44660 nothad; zero tillage (No-till) with a Sunflower 9421-20 seeder) and the influence of mineral fertilizers (N₆₀P₆₀K₆₀ kg a. i.) and straw destructors (ammonia saltpeter in a dose of N₁₀ kg. a.i. per 1 ton of straw and Stimix ® Niva biologics, 2 l/ha) on changes in the yield and quality of Yakov variety oat grain. The traditional system of soil tillage provided the yield of oat of 4.82 t/ha when using mineral fertilizers in a dose of N₆₀P₆₀K₆₀ together with ammonium nitrate as a straw destructor, which was 1.04 t/ha (LSD05 =0.72) higher than the best result in terms of the yield of this crop obtained when it was cultivated using the No-till technology with the Stimix@Niva biological product on the background of N₆₀P₆₀K₆₀ (3.78 t/ha) . Use of the studied straw destructors is more effective for the N₆₀P₆₀K₆₀ background than for the non-fertilized background for all the studied soil tillage systems. When growing oat using No-till technology, the largest mass of 1000 grains was obtained when using ammonium nitrate - 46.5 g compared to other studied variants of using fertilizers and biologics (40.8-43.9 g, LSD₀₅ =1.1). Due to the unfavorable weather conditions of the growing season in 2019, the indicators of oat grain-unit were low. The lowest average grain-unit was found in oat cultivated using zero technology - 228.4 g/l, which is 16.2-18.4 g/l (LSD₀₅ - 3.0) lower than this indicator of grain quality when cultivated according to the rest of the studied tillage systems (244.6-246.8 g/l).

The article deals with the problem of stable operation of various structures of drainage systems on heavy soils in the natural and climatic conditions of the Novgorod region during the first years after construction and after 30 years of operation. The experiment examines the effectiveness of drainage using shallow drainage structures with the depth of 70 cm and two variants of medium-deep drainage (110 cm) with filling the drainage trench with sand-gravel mixture (PGS) and wood chips to the arable horizon. Analysis of groundwater dynamics showed that the rate of groundwater decline in the early spring period in the first years of operation on all experimental variants was approximately the same: 2.0-2.4 cm/day. In recent years in the shallow drainage variant, the decrease in ground water levels occurred more slowly (2.3 cm/day) compared to the standard drainage variants (3.8-3.9 cm/day). The average humidity of the root layer of the soil during the growing season in experimental closed drainage systems has not increased for 30 years. The average moisture reserves for the growing season in the experimental systems were: 177 mm in the shallow drainage variant in 1991, 168 mm in 2018; 165 and 154 mm for the standard drainage with drainage chips backfill, respectively; 164 and 123 mm in the PGS backfill variant, respectively. The highest reliability and durability were shown by collectors with PGS backfill of the drainage trench, which have maintained a consistently high efficiency over a thirty-year period. During the drought period, shallow drainage systems provided more favorable conditions according to the degree of moisture in the root layer: in 2018, the shortest period of moisture lack in the root layer of the soil (10 days) was observed in shallow drainage systems, and the longest (1 month) - in systems with backfill of the drainage trench with PGS.

The purpose of the research is to study the effect of extractive substances from a complex of herbs (R. Carthamoides, S. Coronate, F. ulmaria )on individual indicators of the metabolism of laboratory mice, pregnant sows and piglets obtained from them. A phytoextract containing ecdysteroids and flavonoids was orally administered to white mice ( three experimental and one control group of 15 mice) in doses of 0.1; 0.2 and 0.3 ml during 14 days that provided an increase in the average daily weight gain by 20.8-48.5% (P <0.05) in comparison with the control. The introduction into the diet of pregnant sows (three experimental groups and one control group of 10 sows) of an additive containing a phytoextract once a day at doses 3, 5 and 10 grams per head within 30 days before farrowing did not cause deviations from the norm of the studied biochemical blood parameters (total protein, albumin, cholesterol, calcium, phosphorus, magnesium, urea, creatinine, ALT, AST). The blood parameters of sows in the experimental groups characterizing the metabolic status of the organism were within the reference limits: total protein 60.7±0.4-62.0±0.3 g/l; albumin 44.2±0.4-52.7±1.8 g/l; cholesterol 2.14±0.04-2.90±0.01 mmol/l; Ca 2.50±0.05-2.62±0.01 mmol/l; P 2.91±0.0-3.16±0.04 mmol/l; Mg 0.92±0.02-1.28±0.01 mmol/l; AST 27.6±2.4-29.3±0.5 units; ALT 23.7±1.1-26.9±1.3 units; urea 4.8±0.2-7.9±0.5 mmol/l; creatinine 101.2±3.5-110.0±2.1 mkmol/l. The number of newborn piglets obtained from sows in the experimental groups exceeded the indicator in the control (127 heads) by 6.2%, of which live by 10.6% (in the control, 113 heads), the number transferred for weaning by 11.2% (in control 107 heads), gross growth by 9.8% (control 887 kg). The rest of the studied parameters of piglets (average weight of a piglet during transfer, average daily growth, survivability) did not differ significantly from the control (P> 0.05). It has been established that the phytoextract had an anabolic effect on white mice, did not cause a negative effect on the studied biochemical parameters of metabolism in pregnant sows, and contributed to an increase in the number of live newborns in comparison with the control.

The chronology of extinction and restoration of the Eurasian beaver population in the Kemerovo region is analyzed. The beavers exterminated at this territory at the end of the 18th century were reintroduced 60 years ago. The animals of Voronezh, Smolensk and Belarusian origin were used as the pedigree material. The stages of formation of the Castor fiber population through artificial and natural resettlement and the vectors of dispersion over the main rivers of the region are investigated. The first stage of formation of the Kuzbass population lasted more than 30 years, until 1995. There was the formation, enlargement and closure of isolated colonies into a meta-population. The animals actively settled and developed the most favorable habitats. The second period, which lasted almost 20 years, can be conveniently classified into three stages of rapid growth in numbers, which alternated with stages of relative stabilization. During this time, beavers settled in all large river basins, began to explore anthropogenic landscapes and began to appear near of human settlements. The assessment of the current spatial distribution of beavers in the conditions of the foothills of southern Siberia is made. On the model territory in the east of Kuzbass - the Kuznetskiy Alatau Nature Reserve and adjacent areas - the dynamics of the development of mountain streams by beavers in the absence and/or minimum hunting pressure is shown. Specialized protected area have played an important role in the formation of the modern Kuzbass beaver population. Now beavers have formed stable settlements even in the zone of subalpine meadows at altitudes up to 1350 m a. s. l. and migrate through mountain passes to the Krasnoyarsk Territory and the Republic of Khakassia. The current population of the Eurasian beavers in the Kuzbass exceeds 18,000 individuals, however, this important hunting resource is not exploited efficiently enough. If this trend persists, supported by the weak economic interest of trappers, the further development of the Kuzbass population of the Eurasian beaver will largely be determined by natural factors.

The article provides a theoretical analysis of the process of milk movement from the milk chamber of the collector through the milk hose to the milk pipeline using a continuous model of the plug flow of a two-phase medium. There have been obtained analytic expressions that allow determining the values of pressure drop in the descending and ascending sections of the milk hose. According to the results of the theoretical analysis for two-stroke milking machine of pairwise action there was obtained a linear dependence (R2=0.9965) between the pressure drop in the milk hose and intensity of milk production. Experimental studies of the value of the pressure drop in the milk hose of the milking machine performed in a cowshed for 200 heads of one of the leading enterprises of the Kirov region confirmed a very close relationship (R² = 0.9967) between the current intensity of milk production and the pressure drop in the milk hose when the milk-air mixture moves. Over the entire range of variation in the intensity of lactation, the pressure loss in the descending section varies in the range Δр_тр12 = 0.85…1.47 Pa. According to the absolute contribution to the total pressure loss Δр_1-3 = 8293.80…12705.32 Pa, the pressure loss for overcoming gravity force in the ascending section of the milk hose Δр_гр = 6611.31…10992.27 Pa has the greatest influence. The results of calculations of the pressure drop in the milk hose performed according to the algorithm proposed in the article, fit into the confidence interval of the experimental measurement of the pressure drop with a 5% significance level. Using the results of the research will allow to predict pressure losses in the milk hose in dependence to the intensity of milk production and take into account the results of calculations when designing milking machines and developing their functioning algorithms for milking high-yield cows.

The research is aimed at profound study of the influence of the "machine" factor (M) in the "human-machineanimal" system ("H-M-A") with the detailed description of the functions performed by "M", taking into account the convey of "M" control and control functions from the subsystems "human-operator" (HO) and "animal" (A). The paper presents the scheme of transformation and expansion of machine functionality in a biotechnical system; mathematical modeling of the dependence of technological signals controlled by the functions of local biotechnological systems (LBTS); mathematical model of diagnostic signals about the corresponding parameters of technical blocks of LBTS. Algorithmization and digitalization of processes on a dairy farm include an extended list of control indicators: technological signals, diagnostic signals and "alarm" signals presented in the article in matrix form. Monitoring the parameters of the most important subsystem "M" of the complex biotechnical system "H-M-A" of a dairy farm provides an increase in the level of automation, digitalization and intellectualization of the corresponding processes of milking, feeding, manure removal and others which creates prerequisites for improving their work and servicing animals as well as increasing the level of autonomy of their functioning. The development of the "machine" factor of the system is advisable on the basis of the machine-centric model of the LBTS, which will gradually expand its functions due to the transferred control and management functions from the corresponding subsystems "HO" and "A". The control parameters are determined at the characteristic reference points of the quarter curves of milk output for the development of refined algorithms for controlling the milking processes of individual udder shares in automated and robotic milking machines of the new generation. A graphical and numerical model of a wheeled feed-pusher robot in the Matlab/Simulink environment is shown. The created mathematical model of motion control by a wheeled feed-pusher robot provides effective interaction of the positioning system and the wheeedl robot drive in digital of autonomous movement.
