Study on influence of increasing dozes (0, 30, 60, 90, 120, and 150 kg of acting matter) of full mineral fertilizer on productivity of different spring wheat varieties was conducted in six-field grain-grass crop rotation on long-term stationary of the North-East Agricultural Research Institute. Soil of experimental field is middle-clay sod-podzolic type formed on eluvium of Perm clay. Agrochemical parameters of arable layer before sowing were as follow: рНKCl – 4.8, content of Р2О5 – 46 mg/kg, К2О – 160 mg/kg of soil, humus – 1.5%. Mineral fertilizers were applied by hand in spring before pre-sowing cultivation. Ammonia nitrate, double super-phosphate, and potassium chloride were used as well. Productivity of the most part of varieties increased along with rise of dozes of mineral fertilizer up to N90P90K90 and in variety Svecha – up to N60P60K60. Input of higher dozes of NPK does not lead to increase in productivity. Maximal productivity of spring wheat in average for 18 years was 4.14 t/ha at application of full mineral fertilizer in doze 90 kg of acting matter, when productivity in control was 2.48 t/ha only. Recoupment of 1 kg of acting matter of entering fertilizers with grain of spring wheat was 3.6-8.0 kg in average for 18 years. The highest recoupment was in variant with minimal doze of N30P30K30 – 8.0 kg of grain. Each increase in doze of fertilizer led to lowering in recoupment with grain of spring wheat. In 1978-1980, variety Leningradka had maximal productivity 5.12 t/ha among all studied varieties at doze of fertilizer equal to N120P120K120. Productivity of spring wheat is governed mainly with use of nitric and phosphorus fertilizers, influence of potassium fertilizer was lower. At cultivation of spring wheat after clover, whole doze of fertilizer must be introduced in basic application before sowing. Apply of top-dressing with nitric fertilizer at flowering stage had no significant influence on productivity of studied varieties and content of protein and gluten in grain. Cultivation of spring wheat at application of full mineral fertilizer at doze 60 kg of acting matter per ha was the most effective economically.
Key words: sod-podzolic soil, mineral fertilizers, productivity of spring wheat, variety, recoupment of fertilizer with grain, economical effectiveness of fertilizers.

The varieties testing and the experiments were conducted on turf-podzol heavy clay loam soils widely spread in the Permsky Krai. These soils were characterized by the average cultivation. The experiments had been set up in accordance with the commonly accepted methods, agrotechnology in the experiments had been adopted to the zone system of agriculture. The agrometeorologic conditions at the variety testing and at the conducting the experiment strongly differed at periods during the particular years. The meteorological condition differences at these years allowed us to estimate the varieties having been tested according to their ecological plasticity and stability. The varieties being under consideration the Clover Meadow Permsky Mestny, Trio, Kudesnik created the similar yielding capacity. At sharp changing of the agroclimatic conditions the yield capacity of the varieties under consideration also differs therefore proving their low ecological stability. The weather conditions considerably influence the morphological and physiological indexes of plant development. The article is supplied with the comparative estimation of the level of yield capacity of perennial grasses grown at the state varieties sites, the Academy experimental field and at the agricultural organizations of Permsky Krai, that are the places with high and low level of farming. It has been established that the average yield capacity of the dry matter of perennial grasses in Permsky Krai is 2.9-3.5 times lower than at the state varieties sites of the region and of Perm State Agricultural Academy.

Conditions of growing effect on the area of spruce stands drying up in Bolchesosnovskii, Okhanskii, Ocherskii forest divisions of Permskii Krai were analyzed. Based on acts of nature investigations it was established that for 7 year period (2010-2016) spruce stands drying up has taken part in 280 sites. The drying up was observed in 7 forest types (green moss spruce stands, sour, lime, grass, simallzavine, green mess sour pine stands). As to the areas where spruce trees drying up was fixed, green moss spruce stands (45.35% of the area) and sour spruce (36.58% of the area) have the leading positions. Spruce stands in more productive forest types – lime spruce stands and small ravine forest stands appeared to by more stable as well as the ones growing in green moss and small ravine pine stands. The least stable is the planting of spruce wet, because these plantations account for 16.36% of the wooded area, while the proportion of square cells with shrunken spruce forest stands of this type forest amounted to 45.35%. The share of spruce forests linden forest type is 18.6% and the percentage of square areas with dried vegetation in this forest type does not exceed 4.08%. The stability of spruce stands in different forest types should be taken into account in silvicultural measures planning as well as in future forest stands composition forming.

Under the conditions of a two-year of vegetative experiment we evaluated the effect of a liquid complex fertilizer (LCF 11: 37: 0) on the yield and quality of grain varieties of peas «Stabil» in Nizhnii Novgorod region in 2015-2016. The light gray forest soil is light loamy, low-humus, with a slightly acidic (2015) or close to neutral (2016) pH, has a mean or enhanced provision of mobile compounds of phosphorus and potassium. Fertilizer was added to the soil prior to seeding, at doses of phosphorus from 0.1 to 0.4 g / kg soil; the background fertilizer — NK dose of 0.1 and 0.2 g / kg, respectively. To evaluate the effectiveness of fertilizer we used indicators of the structure of the commodity crop yield and aboveground biomass of grain, grain protein content, fiber, fat and ash. Fertilizer demonstrated its high efficiency in the background compared to the absolute control. It was found that the addition of phosphorus in the composition of a liquid complex fertilizer to nitrogen and potash background is effective, helping to improve the yield of green vegetative mass and grains (15-40%), the amount of beans per plant (increase to 0.34 pc. /plant) and seed in a pod (increase to 0.31 pcs/bean) compared to N0,1K0,2 variant (background). Quality of grain peas from liquid complex fertilizer was improved by the increase in protein content (25-26%) while maintaining fat, fiber and ash in the range average statistical of published data. Maximum agronomic efficiency was obtained by introducing liquid complex fertilizers in the dose of phosphorus an equal 0.3 g / kg of soil (the ratio N: P: K in the fertilizer composition, which were used for the nitrogen-fixing culture was 1.0: 1.6: 1.1).

At the Department of Farm Machines of the Perm State Agricultural Academy, the estimation of vibro-pneumatic separator with an improved design by the seeds’ purification from lightweight impurities is curried out. Different experimental research methods (laboratory, including the method of experimental planning, and industrial) are used by the achieving this goal. By the solution of a compromise task based on the experiments with the vibro-pneumatic separator with the vacuum chamber it is stated that at the tuning feed value Q=1000 kg/h the degree of impurities’ output is over 97 % while seed loss into waste comprises 7,5 %, at vibration amplitude A=0,015 m, longitudinal deck tilt β=6…7º, installation angle of deck edge α=22…26º, directional angle of vibrations ε=30º, and frequency of deck’s vibrations n=450…460 min-1. Industrial researches of vibro-pneumatic separator with the vacuum chamber showed that at the tuning feed value 1000 kg/h seeds’ output amounts to 90 % while degree of impurities output is 96,3 %. Under the given experimental conditions and machine parameters the content of weed seeds is within 0-3 p/kg, other crop seeds – 0-6 p/kg, unit weight of seeds – 798,4-799,65 g/dm3. Laboratory experiments of vibro-pneumatic separator with force-chamber gave the following results: the degree of wild oats output from the wheat seeds reaches 96% by the output of them at 79 %. Frequency of deck vibrations is 430-450 1/min at the amplitude 0,015 m, cross and longitudinal tilt, respectively, 0 and 5 degrees.

The ensuring of uninterrupted operation of the technological and energy equipment which is involved and is planned to be involved belongs to one of the important tasks. At solving this problem the transition to the system of technical maintenance of the agro-engineering structures in their current condition is of a special interest. Monitoring the technical condition, the metal structures in particular, is made difficult by the low observability of the hidden processes of degradation of the technical condition of the exploited engineering systems. It is suggested to use electrical conductivity of metals and alloys that refers to their structural-sensitive physical properties as one of the diagnosed parameters. To facilitate the constructive realization of monitoring the technical condition of metal structures it is suggested to use the ratio (principle) of Wiedeman-Franz-Lorenz. The measuring of the electrical conductivity of metals is technically carried out easier than in the case of their thermal conductivity. There has been specified the dependence of the Lorentz Lo from the molar heat capacity c_ (rμ) metals and alloys in a recording of the type Lo=π^(2/3) kc_pμ/(e^2 N_A), where k is a Boltzmann constant, e is an electron charge, NA –a number of Avogadro. At room temperature cpμ=3kNA, that allows to come to the ratio Lo=3π2/3k2/e2, known from the quantum theory. These equations correspond to the known dependencies which are experimentally confirmed (by the other authors) in a wide temperature range for the particularly pure metals, and for the alloys. The necessity for the further research has been underlined.
Key words: metals, alloys, engineering design, the current technical condition, technical condition control, thermal conductivity, electrical conductivity, the Wiedemann-Franz-Lorentz principle, the Lorentz number.

One of the main problems of the livestock industry is forage production and animal feeding. Development and implementation of high-tech devices for mixing, expanding their scope, increasing the reliability of their operation, lowering of power consumption and top-quality products is one of the main and priority tasks in the mechanization of livestock and for the industry as a whole. The article proposes a solution to the problem of fodder production through the introduction of new structural and technological solutions used in feed preparing machines. The paper describes proposed installation for the preparation of mixtures and investigations on the quality of the mixture when introducing portions of the components. For the quality and stability of the mixture we used indicators of stability to coalescence (complete separation of the environment into its component phases) TC, and full stability (before the appearance of any visually observable changes in the composition of the sample) of the vehicle. The hexagon to two factors was implemented. The first factor was the frequency of rotation n, and the second – time of mixing t. The homogeneity of the resulting dispersion was estimated according to Cochran’s criterion values were Gоп1=0.010 and Gоп2=0.866 at the number of degrees of freedom f1=2 and f2=7. And the adequacy of the equations was tested using the F-Fisher criterion, at the five percent significance level and the number of degrees of freedom f1=4 and f2=14 — calculated values of F-criterion Fрасч1=2,223 and Fрасч2=1,3. In the study dynamic viscosity was bodyactive μ=1,002 (N•s/m2)•10-3, while the most stable state while cooking is at speed n=1000 min-1, and time t=3min, the optimal values of indicators of quality of mix will be as follows: stability of coalescence TC=98 hours, complete stability TC=57 p

In the current economic conditions the usage of organic and mineral fertilizers is being minimized. This policy of farming had led to such a level of content of organic matter in the soil that it shows its degradation and the low efficiency of fertilizers application for agricultural crops. The main sources of supplying the organic matter in soil are organic fertilizers and post-harvest residues. The article gives a brief survey of the experiment data on the usage of plant residues and their role in humus balance maintaining in turf-podzol soils at the Non-Black Soil Zone of Russia. The survey of native experience of the usage of the reaped-rooted residues at the Non-black Soil Zone for maintaining the soil fertility and for humus balance non-deficiency at turf-podzol soils had displayed that the data on the amount of the coming plant residues coming to the soil after harvesting are very different ( according to some authors’ data). This can be possibly explained, firstly, by the natural variability of the crops, secondly, by the different height of cutting the plants at harvesting, thirdly, by the various methods of determining the reaped-rooted residues. The many-year research has established that the leaders in accumulation of plant residues were the perennial grasses, therefore their introduction into crop rotation was to be of an urgent necessity so that it promoted the economical increase of organic matter coming into soil in a form of plant residues, that allowed (on the background of organic and mineral fertilizers to solve the problem of reproduction of the soil humus to its non-deficiency balance.

In the experiment, the analogues of the control group were fed basic diet of the farm. Weaned piglets of the second group were fed bentonite additionally to the basic ration with the particles diameter depending on their age: at the first feeding stage (2 months) particles diameter was 4-6 mm, at the second stage (3 months) – 8-10 mm. It was established that piglets fed with bentonite had a tendency to increase of dry matter digestibility coefficient by 1.8 % in comparison to the coefficient in the first group. Dry matter digestibility was (Р≤0.05) by 2.3 % higher in the second group. As a consequence of the fact that the bentonite clay possesses adsorb features, crude protein digestibility coefficients increased (Р≤0.05) by 2.3 %, and nitrogen-free extractives – by 2.9 %, respectively, in comparison to the first group. The animals of the second group better digest protein, since the content of digestible nitrogen was by 3.4 % more compared with the piglets of the first group. Balance of calcium in the first group amounted 5.57 g or 41.13 %, in the second group – 5.92 g or 43.56%, by 0.35 г or by 2.13% higher than figures of the first group. Balance of phosphorus in the first group amounted 32.80 %, in the second – 36.24 %. Difference in the groups constituted
3.4 % for the benefit of the second group that influenced the growth intensity. Feeding with bentonite allowed decreasing the concentration of heavy metals in blood. Increase of nutrients digestibility coefficients in the experimental group was noticed, as well as better digestibility of nitrogen, calcium and phosphorus, increase of slaughter output in weaned piglets in the experimental group compared to the control group by 1.8 %.
Key words: weaned piglets, bentonite clay, digestibility coefficients, heavy metals, lethal exit.

In the situation of the small towns the working dogs (the males of German Shepherd Dog breed) had been fed both with dry ready-made commercially produced feed of the brand Royal Canin MAXI Adult GR 26 and with that made of natural products ( in the quantities determined by the order of administration . Both types of feeding had ensured the equal (according to the quantity of dry matter) animal daily need but had been different in volume due to the technology of the feed prepared. In the physiological experiment the dogs kept on a diet based on the feed made of natural products consumed the nutrients in a better way due to the higher energetic food value at 8,19% in comparison with the experimental group. During the research it has been established that the coefficients of digestibility of nutrient substances had been lower concerning the experimental group of dogs (fed with the ready-made feed) in comparison with the group of animals consuming that prepared of natural products at the following values: in raw protein – at 2,09%, in fat – at 1,98%, in crude fiber — at 1,9% (P < 0,05), in non-nitrous extractives – at 5,46%, in organic matter — at 4,23% and in dry matter in general – at 4,65 %. The morphological study of the semen of the male dogs of the experimental group revealed that the spermatozoa concentration in the semen was at 278.5 mln/ml, that had been at 99,50 % (P<0,01) lower in comparison with the control group, therefore/thus having more pathological forms of sperma. The testosterone concentration in the male dog’s blood exceeded the norm index of healthy animals at 25,47 % in the control group and at 31,05 % in the experimental one. Concerning the biochemical composition of blood, no clear/distinct/certain difference/distinctions in the indicators of the groups had been found/ revealed. There was established in the course of the experiment that the transfer of the animals from feed prepared of natural components to that of the ready-made dry feed had caused a deterioration of the quality of the sperm received from the male dogs and of their harmonic status as well.

For many years scientists from Russia and abroad are conducting research in the field of feeding dogs a complete dry food. Experiments on the use of prepared feeds show that often their quality is low and negatively affects the health of dogs. In veterinary medicine, feed dietary supplements of plant origin are widely used for feeding to improve digestion and absorption of nutrients, as well as to correct and normalize the metabolism. The composition of biologically active additives «Transversal» is composed of herbal ingredients: TRANS-resveratrol and quercetin, which prevent the development of cardiovascular diseases and their complications, as well as premature aging. We conducted a research on studying of influence of biologically active additive «Transferal» on morphological and biochemical composition of blood of dogs. It was established that the studied dietary supplement accelerates the metabolic processes in the organism of dogs. Thus, the number of red blood cells in dogs of the experimental group was higher compared to counterparts in the control group on or 25.9% (P<0.05). The level of hemoglobin in dogs of the experimental group tended to increase compared to counterparts in the control group by 11.34 g/l, or 6.7% (P<0.05). The level of monocytes in dogs of the experimental group was 5.00±0.25% (P<0.01), which is 1.67% higher than in the control group. At the end of the experiment the value of total protein in the whey of blood in dogs of the experimental group tended to increase compared to counterparts in the control group 6.54 g/l, or 9.4% (P<0.05). The blood sugar in dogs of the experimental group at the end of the experiment decreased compared to the control group and amounted to 3.41 mmol/l, thus, increased antioxidant function and improved functional status in dogs prone to excessive sugar in the blood.

In the context of the Republic of Bashkortostan in the period from 2012 to 2015 norms of feeding the probiotic «Vitafort» were studied in compare with economic control without probiotics and probiotic «Vetom». The study was conducted in order to determine the effect of probiotic «Vitafort» on the intensity of growth and development of piglets, their safety, and the use of nutrient digestibility of the diet substances, hematological and biochemical parameters of blood. The animals in the control and experimental groups were selected by the method of pair-analogues of weaned pigs grown under identical conditions and feeding. The diet of animals in the control and experimental groups was identical. The only difference was that the piglets after weaning in the experimental groups were fed the probiotic «Vitafort» in the morning before feeding for 5 days, followed by 7-day intervals. Probiotic was fed by the oral route. Duration of the experiment was 60 days. It was formed 5 groups: Group 1 – control-1 without probiotic, Group 2 – control -2 probiotic «Vetom» – 1.5 g / day / head,
3 group – experimental-1 with 0.05 ml of the probiotic «Vitafort», group 4 – experimental-2 with
0.5 ml of a probiotic «Vitafort» group 5 –experimental-3 – 1 ml probiotic «Vitafort». The daily dose of the probiotic feeding «Vitafort» is shown per 10 kg of live weight of pigs after weaning. The use of a probiotic «Vitafort» in rations of weaned pigs of Large White breed at a dose of 0.5 ml per 10 kg body weight contributed to an increase in average daily gain by 21.5% higher than in the normal control group (P <0.01) and by 12.4% than in the second control group with probiotic Vetom (P <0,05). Increase of digestibility (P <0.05) of crude protein (78.2 instead of 73.0% in the control) and the digestibility of nitrogen-free extractives (92.4 instead of 87.3% in the control) was revealed. Balance nitrogen, phosphorus and calcium were also the best in the fourth experimental group. The results of studies of the blood composition in showed that the studied parameters in all groups were within the physiological norms, but using probiotic «Vitafort» leads to an increase of indicators such as total protein, calcium, phosphorus, inorganic and reduced urea, compared with the first and second control groups (P <0.05).
Key words: pigs after weaning, growth and development, and probiotics “Vetom”, “Vitafort”, digestibility and nutrient digestibility, morphological and biochemical indices of blood.

The article presents a comparative analysis of the Salmonella isolation methods from meat and meat products. The aim of research was exploring the possibility of Salmonella isolated from meat and meat food products. The work was performed at the bacteriological department of the Perm Veterinary Diagnostic Center during 2014-2016. The material for the artificial contamination were strains of S. Typhimurium, S. Enteritidis, S. Gallinarum-Pullorum, S. Dublin, S. Choleraesuis, S. Infantis, S. Hamburg, S. Virchow, obtained from the State Organization «Scientific Centre for Expertise of Medical Products» of the Russian Ministry of Health and ones isolated from meat and egg products (n = 46). The test samples of meat products weighing 25 g contaminated by Salmonella suspension consist of 101 to 108 bacterial cell/cm3, homogenized and analyzed as an experienced and control (by GOST 31659-2012) methods. We used bacteriological method of research. During the investigation review, we consider the sensitivity of the methods and the rate of typical colonies formation, possibility of bacteriophages lysis, biochemical and serological properties of Salmonella, and time spent on research. Result of studies show that the developed method for isolating Salmonella exceeds the classical analogue. In particular, the sensitivity of the developed method is only 10 bacterial cells of Salmonella. After Salmonella spp. accumulation by self-constructed medium ones formed typical colonies into agar more quickly than when using standard nutrient broth. Thus, full analysis by our method takes 50 — 70 hours less depending on the number of viable Salmonella cells within the sample. It is important, that this method of Salmonella spp. isolating precludes false-negative results of analysis. This fact certainly contributes to the quality of food.
Key words: Salmonella spp., meat and meat products, sensitivity, typing, time.

The theoretical aspects of the organizing of the effective development of the native agro-industrial complex in the conditions of the current economic uncertainty have been under consideration. The improvement of the mechanisms and implements of the agrarian activity management nowadays goes under the aegis of ideological innovations, the correlating influence of surroundings factors, mutually forming the preconditions for organizational renovation of the process of management. Re-considering of the scientific approaches and their practical transforming conditions the necessity for the improvement of the apparatus of the categories, marking the theoretical aspects of building-up of business processes of management decisions on organizing the effective development of the agro-industrial complex. On a basis of the research conducted (that is summarized in the article) the specified definitions of the categories “effective development” and “effective development of agro-industrial complex in conditions of current economic uncertainty” were added and introduced in the scientific surroundings. The unique quality of the author’s supplements to the agrarian economic theory is that reflecting the strategic objective-providing the public reproduction in the interests of today’s population and of the future one, these supplements consolidate the main forms of development (evolutional and transformational) and the directions of their realization. On the foundations of the theoretical research for formation of adaptive institutional surroundings for managing the agrarian production there had been based a necessity of introducing the process approach, that differs by the more complicated algorithm of actions than a traditional structural-functional one and the typology of business processes had been fulfilled. There had been formulated a thesis on the necessity of further development of the theory of the effective development of the agro-industrial complex in the direction of concreting the tasks of the institutional building-up on the basis of developing inner-branch and inter-branch interfering, stimulating the organs of management to the search of optimum structure and inner-system defragmentation of rights and responsibilities.

The article gives the consideration of the problem of import phase-out as a new economical phenomenon guaranteeing a substitution of providers of import provision by the Russian producers of goods (in conditions of agricultural production modernization). There had been made a sociological inquiry for estimating import phase-out in the conditions of sanctions economy. The author’s definition, the principles and the system of import phase-out have been given. The factors forming the dependence on the import and the import phase-out have been distinguished. There have been worked out and presented the principal directions of import phase-out of agroindustrial complex for Permsky Krai, these underlining the necessity for technical modernization of the branch, innovational machine-building creation, modernization the finance-credit system and innovation technologies. The current economic situation dictates the necessity of import phase-out at the market of agricultural technics so that the technical dependence may transform into a technological one. The import phase-out cannot be achieved without a synchronic and carrying out ahead development of the other branches of economy that tells us of a necessity for adopting a federal inter-branch program for import phase-out of agricultural product and provision, of production of resources providing the development of agro-industrial complex. At this the scientific providing must be the full-rights component of this program.

The research is aimed at searching for optimum values of the level of the outer surroundings of agricultural producers of the three categories: agricultural organizations, farms, town farms. There has been displayed the theoretical-methodological approach, in terms of which the methodology of using an integral indicator of estimation of a potential of agriculture of a territory of well developed ( in the agricultural aspect) region has been carried out. On a statistic analyses base we proved that, having the optimum of outer terms(conditions) the producers of goods were able to increase gross production of agriculture considerably. However, the optimization of the outer surroundings of an agricultural branch is a complicated task. For solving the problem of its studying there has been applied a system of methods: 1. The usage of the results of the accomplished research, specifying on the presence of the influence of the certain outer factors on farming; 2. The author’s systematization of the knowledge about outer factors constituted in its classification with differing/separating to the groups of economic, political, social, technological, informational, ecologic, natural, law, military factors presented at the consistent/successive/gradual hierarchical levels of the global, national, regional and branch outer surroundings. 3.Conducting to the correlated form all the factorial elements, influencing the results of functioning of the agrarian sector, but having the different units of measurements, and the revealing the collective force of influencing all the levels of the outer surroundings on production at agricultural organizations, farms, town farms; 4. Determining the purpose-oriented levels of the factors of outer surroundings which maximize agricultural production on a basis of built equations of the developed equation of multiple regression. There has been presented the accounting statistics of the potential of the production volume of agricultural product at North-Caucasus Region.

Illegal logging which are being carried out in a great scale in Russia is not only one of the most important indicators of instability of the forest management but one of the main obstacles to its introduction as well. They lower the motivation of the owners of forests and the forestry employees for stable forest management. The problems of revealing and detecting the crimes in forest industry complex are under consideration in the paper. The statistic data reflecting the indicators of activity of forestry complex of the Permsky Krai for the last years had been used in this research. There had been offered the methods for revealing and determining the criminality level in the sphere of FIC (forest industry complex), including the estimation of the illegal turnover of timber, presented by the carrying out the criteria and the methods of determining the damage of the criminal economic activity of the forest industry complex field to the state. The applying of implements suggested for detecting the crimes in the FIC helps to estimate and sometimes to prevent criminalization in this sphere.
