Abstract
The paper presents the data on the analysis of rabies manifestation characteristics and the role of wild animals in the formation of natural focus of the infection in the transborder land of Russia (Buryatia) and Mongolia. In Mongolia, rabies was registered in 15 out of 22 aimaks. The highest indexes of animal morbidity recorded in 2010 were revealed in Bulgan and Khovsgol aimaks. In 2011, 58 animals got sick that was 57.7 % as little as in the year 2010. In 2010, the main part to maintain the natural focus of the infection was played by the fox (56.1 %) and the wolf (33.3 %), and two cases of the disease were revealed in the bat. The share of livestock made up 45.8 and 55.2 % in 2010 and 2011, respectively. In 2011, rabies diseased animals- wild and domestic- were recorded in Buryatia’s Zakamensk area bordering Mongolia, 25 km north off the border line. A mere 32 samples were examined in the republic research and production laboratory; of them, 15 results (46.9 %) were positive. The causative agent was detected in 7 foxes, 1 badger, 1 wolf, which constituted 60.0 % of the total positive results.

Abstract
The tests of α-cypermethrin in the form of water emulsion and aerosol were carried out during cattle demodecosis. The efficiency of 5 g/l α-cypermethrin water emulsion was studied with the method of cattle local treatment in the concentrations 0.3, 0.5 and 0.75 % versus 5 g/l α-cypermethrin aerosol («Alpha-spray»). To test 25 animals were selected with the method of analogs and divided into 5 groups (4 experimental and 1 control). Demodecosis was diagnosed clinically in all the animals. The experimental animals were treated by local placing the preparations on the damaged parts of the body 3 times with 5-7 day intervals (groups 1-3 received 200-300 ml of α-cypermethrin water emulsion in 0.3, 0.5 and 0.75 % concentrations; group 4 was exposed to «Alpha-spray» aerosol for 20 seconds. The control animals were treated with water on which base working emulsions were made. «Alpha-spray», the α-cypermethrin aerosol, did not show high efficiency (intensity - 26.4 %), but 0.75 % α-cypermethrin water emulsion possessed pronounced acaricide activity during cattle demodecosis (intensity - 67.2 %; prevalence - 66.7)

Abstract
Multiple experiments and clinical examinations carried out in our country and abroad in the last century 80-90s identified that the infection of bovine leucosis virus (BLV-infection) is an obligatory, but not sole factor for the leucosis process to progress. A secondary, but not less important factor is genetic predisposition to the disease. A tertiary place is occupied by immune deficiencies of both primary and secondary nature (acquired). The most critical (the highest risk) period, when animals are likely to get BLV infected, is an early postnatal one (up to 30 days of life) due to the characteristics of immunologic resistance formation in this period. In relation to this, the advantage to take passive immune preventive measures against BLV is justified, the technique to make goat’s hyperimmune serum (HIS) against cattle leucosis virus (BLV) is given. HIS targeted application is shown to prevent early postnatal calves in the infection-vulnerable herds from being attacked by this leucosis infection. HIS is applied once. HIS preventive efficiency was tested on 18 newborn lambs that were experimentally infected with BLV-containing material in the background of HIS single dose per os. The effect was 100 % preventive. The infection level made up 50 % in the control group of calves (no HIS applied)

Abstract
The paper studies changes in the activity of enzymes (aspartate aminotransferase, AsAT), alanine aminotransferase, AlAT), alkaline phosphatase, AP), gamma-glutamate transferase, γ-GTF) in mice’s liver supernatant in the background of cadmium intoxication. It was identified that in the background of daily receiving cadmium sulfate per os at the dose of 40 mg/animal, liver weight goes down (significantly from the 3rd day of the intoxication), fermentemia progresses with its maximal expression determined both by the time of exposition to the toxicant in the body and the role of fermentative reactions catalyzed by AsAT, AlAT, AP and γ-GTF to maintain metabolic flows in the cells of the liver and body on the whole. Thus, the activity of aminotransferases in the liver supernatant maximally increases the day after the intoxication start reflecting the level of catabolic processes; that of alkaline phosphatase - on the third day characterizing the level of power deficit; γ-GTF - on the eighth day determining the degree of amino acids borrowed from the body tissues. Fermentemia is the index of liver compensatory possibilities and dynamics of pathological changes.

Abstract
The characteristic of management for ecologically-friendly produce manufacturing is that any action is to be regulated by legal norms. In Russia, there are practically no well-defined standards to estimate the produce as ecologically-friendly. The manufacturers and consumers of ecologically- friendly produce find it urgent to develop and put into practice the mechanism to regulate organic produce manufacture, certification and consumption. The terms «organic produce manufacture» and «organic farm produce» have been coined today. The following provisions were agreed upon, such as state support for and control of organic farm produce manufacture as well as state support for the events to improve soil fertility, protect agricultural lands and realize organic agricultural manufacture. Informational and methodical extension is to be provided for the manufacture of organic farm produce. In the air is the burning issue of designing the mechanism to regulate all manufacturing stages: processing, packaging, labeling, transporting and merchandizing the ecologically-friendly produce as this shall make it possible to enter the world market and make its contribution to more consolidated food safety and support for healthy nutrition of our country’s residents. The main trends of the mechanism are to be the following: to update the legislative and normative base in the field of ecologic agriculture, design the plan of organic produce market advance for long-term perspective on federal and regional level, develop national trade marks for certified organic products, set up sufficient number of accredited bodies to certify, set up the center for providing the information and marketing research regarding the organic produce as well as found the monitoring center for food produce electronic accounting. The events proposed to update the mechanism of organic produce manufacture, certification and consumption shall allow to arrange the manufacture of organic produce in Russia, but this is one of the most perspective trends to provide competitive ability and quality of the products and important source of economic growth.

Abstract
High efficiency of agricultural production is inseparably connected with the development of integration of all AIC organizations. Unless the farm producer receives the equivalent part of the proceeds from produce and stock obtained from the output grown, it is difficult to rely upon the producer’s high motivation. As investigations showed, the proceeds from the sales of the stuffs of processed farm raw material are 3.9 times as much as those from realized farm output of producer’s own. This refers in full to the enterprises of industrial crops subcomplex. Herewith, the profit grows with the producer’s transmitting to low-waste production. The development of low-waste production based on flax produce leads textile enterprises and the ones manufacturing nonwoven fabric, kashtë slabs, and ecologically-friendly and cheap building heat-insulations to be included into AIC. Oil flax is the most high-yielding among the oil crops cultivated in Novosibirsk region. For the data of three-year estimation (2011-2013), the best was Sokol (falcon) variety which productivity accounted for 14 hwt/ha of seeds and this is 1.4 % higher than the standard. In 2010, it significantly exceeded the standard variety Legur by 1.6hwt/ha. The varieties tested are distinguished by the content of fiber in a stem: in 2012, the standard content made up 12.9 %, Yantar (amber) variety - 16.1 %, Bilton - 18.5 %. To improve economic efficiency of industrial crop production it is necessary to transfer the production to the integrated basis.

Abstract
The paper shows changes in agricultural production systems of Kostanaisk region that took place in the period of market relations establishing and advance. It also examines specialization and combination of industries, scope of crop production output, structure of the areas under crops, livestock output in the region at large and for the categories of farms; the paper provides the indexes of agricultural gross output calculated per land area unit. The main problems of production systems advance are revealed for the period examined: abandoning the conventional specialization of agricultural enterprises, spring wheat grain production monopolization, strong variation of crop productivity and the number and productivity of livestock populations with nature and climatic conditions, consolidation of large-scale livestock production in the house holdings of rural people and, as a consequence, poorly managed small commodity production, low animal genetic potential and productivity, insufficient veterinary service. All these are reflected in the indexes of efficient utilization of land resources and result from non-available scientific approaches to the formation of production systems under modern conditions. Based on the problems identified the paper designates the main trends to improve the efficiency of agricultural production systems.

Abstract
The work considers the dynamics and problems of Kazakhstan’s agrarian market advance under the conditions of Customs Union. The main conditions to achieve sustainable development of agricultural output production are: internal support for agrarian production, international integration strengthening in the AIC sphere, innovations and information infrastructure advance, interstate integration, outlets diversification, development of optimal transport routes. The burning issues of this period are the problems of interrelations among states under the conditions of Customs Union development, creation of common free market zone and possible risks of joining the WTO. When joining the WTO and common free market zone, each state anticipates substantial economic benefits, however, there are arising certain risks for agriculture advance to which Kazakhstan’s agrarian sector is very vulnerable. Prerequisites to the risks are natural constrains for farm crops cultivation, raw material orientation, general technical and technological lagging behind, minor integration into world economy, underdeveloped production and social infrastructure. The paper investigates the experience with subsides in the agriculture of developing countries. It provides some recommendations to improve subsidizing a country when it joins the WTO.

Abstract
Theoretical basics of AIC enterprise competitive ability management are considered. The types of competition are analyzed in the course of investigations conducted. Food competition arises between alternative stuffs and the ones substituting each other. The character and intensity of the competition are revealed at food market. Agriculture has the element of high risk related to the inability to promptly adjust to changing conditions. Agricultural producers are not able to control their own output the same way as non-agricultural producers do because the total output grown is determined by the work of many small producers that perform independently and production outcomes largely depend on weather conditions and biological systems. Agricultural producers cannot initiate the immediate production burst along with dramatically rising demand and hence, profit for the producers. These factors testify to high competitive conditions in agriculture.

Abstract
Credit worthlessness status is considered as one of the causes affecting the development of agriculture. The growth of regional agriculture credit worthlessness is determined on the basis of Novosibirskoblstat data (Novosibirsk region statistic) on accounts receivable and the scope of bank loans for agricultural commodity producers in Novosibirsk region. Herewith, it is shown that lately, the scope of bank loans for agriculture have not gone up in Vengerovo area. The number of borrowed funds on the part of agricultural producers does not increase with each year coming. Farms of the area are reluctant to contract debts. It is determined that the consequences of this and other negative processes are disappointing financial conditions of agricultural organizations in Vengerovo area. To solve the problem concerned the municipal authorities are suggested to inform agricultural commodity producers about the possibility to take credits and build up production.

Abstract
The paper provides the data on three-year investigations of growth regulators in 3 potato varieties (Nevsky, Borodyansky Rozovy and Pamyatu Rogacheva). It is shown that under the conditions of Novosibirsk Preobye forest steppe the treatment of potato tubers with growth regulators (el-1 at the doze of 10ml/t, crezacin at the doze of 2g/t and epin-extra at the doze of 1-ml/t) discloses potato bioresource potential. Potato plants passed through all the developmental stages 3-6 days earlier than those in the control, productivity grew by 17-35 % varying with the variety, potato quality indexes improved (starch content increased by 0.3-1.9 % varying with the variety and growth regulator, dry matter and vitamin C went up by 0.3-1.9 % and 0.4-1.4 mg/100 g, respectively. The treatment with growth regulators allowed to decrease the level of nitrates in potato tubers by 6-34 mg/kg). As a result of the investigations conducted one can recommend to apply domestic growth regulators - el-1, crezacin and epin-extra - for production and private households to treat potato tubers prior to planting when cultivating early potatoes in Novosibirsk Preobye. The procedure concerned contributes to increased productivity and quality of early potatoes. The doze of the investigated formulations with working liquid involved at 10 l/t of tubers is to be 10ml/t for el-1, 2 g/t for crezacin and 10ml/t for epin-extra.

Abstract
It was revealed in the leached heavy loam black soils of Novosibirsk Preobye forest steppe that the elements of cultivation technology influence the productivity and quality of potato varieties different in ripening groups: Lubava - early ripening, Nevsky-middle early ripening, Khozyaushka (hostess) - middle ripening. The experiments were conducted in the middle loam black soils containing readily hydrolyzed nitrogen - 8.10-11.76, mobile phosphorus - 16.8-22.4 and exchangeable potassium - 11.2-13.8 mg/100g of soil, salt extract pH - 5.84. The potato varieties examined were grown according to the technology common in the zone that is three-year rotation: bare fallow-potato-spring wheat. Mineral fertilizers doses were calculated with balance method for programmed productivity on the basis of accounted nutrients consumed by the yielding output, coefficients of their having been consumed from the soil and fertilizers. The experiments showed the effect of agrotechnical practices on the indexes of photosynthetic apparatus and potato plants productivity.Leaf surface was calculated with the formulas established by us for the varieties different in ripening groups. Correlation for the formulas established made up 0.798-0.923. The complex of soil cultivations was applied to the varieties different in ripening groups: rotary tillage to the depth of 12-14 cm before planting with subsequent high hilling on the 14-16th day after the planting and this made mean leaf surface to expand by 38% and tuber productivity to go up by 20-32% followed by good qualitative indexes of the produce. Balanced mineral nutrition encouraged gains in potato output in the unfertilized background up to 71%.Optimized fertilizer doses allowed to obtain high quality produce containing nitrites 5 times as little as MPC for potato. It is identified that the planting for all the three groups is efficient when it follows the wide row pattern: 90 x 25 and 90 x 35 cm with 31% productivity gain versus the common planting with 70 cm interrow. Statistics revealed that potato productivity depended on the genotype for 20-28%, technology elements - for 28-42% and seasonal conditions - for 22%. The technological elements (complexes of soil cultivation, balanced doses of mineral fertilizers, planting pattern) studied in the varieties of the three potato ripening groups provide 64% increased profitability with the coefficient of energetic efficiency up to 2.5.

Abstract
Research data testify to the expediency of moldboard soil cultivation with harrowing before and after shoots emergence in forest grey soils of West Siberia’s subtaiga zone for the symbiotic apparatus of grain legumes to develop. Herewith favorable agrophysical properties of soil plow layer are preserved, particularly less compactness and hence, later soil transmission to natural balanced conditions. Growth stimulating preparations and mineral fertilizers encourage better formation and development of nodule bacteria and facilitate the highest productivity of green mass in leguminous crops in uni- and polyspecies sowings. As a result of the research conducted it was identified that in polyspecies sowings, there was observed positive interaction of the mixture components for nitrogen fixing activity and nitrogen consumption by plants, which added to higher rates of biomass formation and sowings productivity. Thus, the highest yield of green mass was obtained in the three-component mixture of oat x pea x broad beans, its best option averaged roughly 33.2-34.5 t/ha, dry matter obtained was 9.51-9.87, feed units made up 8.10-8.89 t/ha, digestible protein and exchangeable energy were 960-1045 kg/ha and 105-126 MJoule/ha, respectively. Moldboard soil cultivation with crops harrowing before and after shoots emergence with concurrent application of growth stimulating preparations and mineral fertilizers encouraged better formation and development of nodule bacteria in all the sowing options. Thus, in pea sowing as a unispecies the quantity and weight of nodules made up 54.6 mln. units/ha and 131.1 kg/ha, respectively. As for polysowings, nodules quantity and weight were 34.7 mln. units/ha and 88.6 kg/ha in a two-component mixture, 47.6 mln. units/ha and 134.0 kg/ha in a three-component mixture, respectively.

Abstract
The basis of proper usage of natural pastures is to know the regulations of formation and development of grass stand, pasturage effects on pastureland status as well as on economic demands for the one. Flora and vegetation ecological analysis allows for more substantial approach to the events on restoration of degraded pastures, their conservation and rational utilization, particularly on the lands of preserved natural territories. The following types of pastures are discerned on the territory explored: small grain-herbs-sedge (Carex), filamentous leaf herbs, herbs-bluegrass, steppe-like herbal meadow, leymus herbal pasture (virgin land). The most productive are herbal steppe-like meadow pasture (5.9hwt/ha) and leymus herbal pasture. Cereal (64 %) and leguminous (34 %) crops dominate among economically valuable plants, nutritious and high yielding ones. Ecological analysis was done in the flora of the most widely spread associations of herbal vegetation of forage land economic types and it showed that xerophytic and mesoxerophytic grass species of Рoaceae, Fabaceae and Asteraceae families dominate in the structure of pasture phytocenoses.

Abstract
To cause herbicide toxic effects on grain crops to go down combined preparations are applied, such as Dialen, Chistalan, Super Dialen, Dimax, Super Biolan and others. However, these herbicides produce toxic effects on plants. Agroecological factors do not have the same effects on leaf square in the crops and biomass accumulation. Leaf surface accumulation in wheat plants in all the variants corresponded to the classical curve of accumulation dynamics. Maximal expanded wheat leaf surface in the control, in the variant with ammonium nitrate treatment, in that with Dialen as well as with Dialen in the background of ammonium nitrate were in the phase of wheat plants shooting. Minimal value of wheat leaf surface in all the variants was in the phase of plants anthesis. Wheat plants accumulated biomass minimally in the control variant throughout the entire vegetation. The variant with Dialen ranks second for the biomass accumulation, the one with ammonium nitrate ranks third. The maximal wheat plants biomass accumulation was observed in the variant with Dialen applied in the background of ammonium nitrate throughout the entire vegetation.

Abstract
Research data are presented on selective herbicides applied to spring wheat sowings and nonselective ones that were applied pre-sown, after-harvested and with fallow fields prepared. To control the complex of weeds of different biological groups under the conditions of minimal soil cultivation with concurrent traditional selective herbicides applied during grain crops vegetation period the system to use chemical means of weed control is required which includes different dates of herbicides application (pre-sowing and after-harvesting) and combined preparations in tank mixtures. It is established that with the treatment during the vegetation the ethers 2.4-D and mixtures based on them are the most effective against root-propagating weeds (particularly willow spurge and field bindweed), but the treatment with herbicide-combined humus growth regulators gives rise to additional grain productivity gain. To control wintering and root-propagating weeds under the conditions of minimal soil cultivation it is necessary to apply herbicides including nonselective ones in winter period or in the fall. When preparing fallow fields to efficiently suppress root-propagating weeds one should substitute herbicides for mechanical cultivation.

Abstract
The most continuous and efficient way to improve solonetz fertility is chemical reclamation that creates conditions for proper development of crop plants. A single application of gypsum in the solonetzes of Novosibirsk region northern forest-steppe produces a continuous reclaiming effect. It is established that for the first two years after the ameliorator having been applied and due to exchange reactions proceeding in the 0-20 cm reclamation layer the content of salts largely rose up to 21-23 t/ha versus the control 3-5 t/ha. The salts were mostly represented by Ca, Mg, Na and sulfate ions. In the subsequent years, when exposed to atmospheric rainfalls and with comparatively stable level of mineralized ground water-tables, the salts were washed through to the lower horizons. From the year 1987 and further, the depth of ground water-tables varied from 240 to 265 cm and this influenced the direction of soil formation process: the degree of soil profile gleyzation went down. In the too wet year 2013, ground waters went up to the 50 cm depth and this intensified solonetz salinization in the gypsum applied option. Solonetz alkalinity increased, carbonates and bicarbonates content, particularly Na cations, rose. Ground waters pH value has been in the alkali interval since the year 1987.The highest value of the index involved was 8.5 in 2013. In the solonetzes with low Na content the salinization process ran more intensively than in those with high Na content. In the fall, ground water-tables went down to 200 cm and reclaimed solonetzes desalted again.

Abstract
Histological method of examination allows to estimate the structure of the pelt in its different topographic parts, which is important from the point of market and technology. Cattle breed influences raw hides quality. Hereford bull-calves exceeded their Holstein x Black-and-White peers for the quality of raw hides. Thickness of derma, cancellous layer and collagen fascicles in all the topographic parts in Hereford bull-calves aged 18 months was higher by 12.5, 37.8 and 57.9 % (Р > 0.01), respectively, than that in the Holstein x Black-and-White peers. This ensured higher physicomechanical indexes of the pelt in beef bull-calves. Elasticity modulus in all the groups exceeded GOST requirements (State Standards) and the highest was in Hereford bull-calves. Leather strength depends on how far its coating withstands multifold bending. With dry rubbing, pelt samples taken from Herefords exceeded the indexes of their Holstein x Black-and-White peers by 7.9 % (P < 0.05), with wet rubbing - by 20.8 % (P < 0.01). Stiffness and elasticity of the pelt from the experimental bull-calves corresponded to standard specifications for soft leather. The pelts obtained from 1.5 year-old Hereford bull-calves and their Holstein x Black-and-White peers are valuable raw hides for the production of soft leather and are suitable for footwear tops.

Abstract
The paper provides the data of the introductory crossing between Precocious Meat sows SM-1 (Kemerovo breeding) and stud-type KM-1 boars. The research data showed that F1 and F2 progenies were characterized by the best fattening and meat traits. When withdrawn from the control fattening, the F1 and F2 animals examined had advantages in daily weight gain and precocity over purebred ones; they increased the indexes by 18.6-11.4 % (Р < 0.001) and 9.0-4.8 % (Р < 0.001), respectively. Hereto, it should be noted that feed costs were little different for groups and averaged a mere 3.71 feed units. The outcomes of control slaughter testify to a high enough level of meat traits in the animals examined both purebred and mixed. The gilts of the blood share 3/4SM-1 + 1/4KM-1 are observed to have the trend to decrease fat thickness from 25.2 to 24.0 mm over 6-7th thoracic vertebrae and increase meat output per carcass from 59.7 to 60.8 %. The animals from the 3rd group are marked to have the trend to increase the content of erythrocytes and hemoglobin in blood: 6.39 · 10 12/l and 100.0 g/l. The gilts of the 3rd group happened to have the content of lymphocytes higher (61.3 %) than their analogs from the control and 3rd groups. On the whole, the analysis of blood readings indicates good physiological state and high natural resistance of the examined animals’ body.

Abstract
Blood serum alkaline phosphatase activity is studied in the pigs of three West Siberia’s breeds: Large White, Kemerovo and Landrace which were kept under equal conditions of feeding and housing. Interbreed differences were identified for the activity of alkaline phosphatase in the blood serum of pigs on fattening, which indicates a certain genetic determination of the trait. Alkaline phosphatase activity was higher in Kemerovo pigs both on 100 and on 120-140 kg fattening and this is characteristic of high adaptability of the animals to West Siberia’s conditions. Landrace animals, when 100 and 120 kg fattened, occupied an intermediate position for the activity of the enzyme studied. In different ontogenesis periods, the lowest activity of alkaline phosphatase was observed in Large White animals. In all the examined periods of growth and development the phenotypic variability of alkaline phosphatase was not high (Сv = 5-9 %) it was the same, indeed, in the animals of the three breeds. With ageing, alkaline phosphatase activity went down in the animals of all the breeds.

Abstract
Not less than 22 amino acids are involved in the formation of animal body tissues. Protein synthesis runs following the genetic code and depends upon the supply of the number required for separate amino acids in the body. If the lack of amino acids can be corrected with synthesis or transamination processes, the deficiency of nonessential amino acids causes protein synthesis to break down. The paramount importance of amino acids for the animal organism made us conduct examinations in Romanovskaya sheep’s bone tissue to identify the content of 16 amino acids, eight of them were essential and the rest was nonessential. The material to examine was lower jaw, shin and breast bones of Romanovskaya sheep. The bone sock was obtained from clinically healthy animals from 11 age groups. Amino acids percentage was determined by ААА-881 automatic analyzer. The numerical material obtained was processed statistically. The examinations conducted identified that the percentage content of amino acids in the sheep’s bone tissues was not permanent and had the indexes varied with animas’ age. Each amino acid has its own certain age when its content in bones has minimal and maximal indexes. It should be noted that the number of amino acids, such as arginine, proline, glycine, alanine and glutamic acid is the highest, while the number of tyrosine, cystin, lysine, valine, methionine and isoleucine is the least.

Abstract
The data of multiple researches point out that the acclimatization of animals is followed by disorders in spermato- and ovogenesis as well as by increased embryo deaths. Decreased reproductive function shows up in poor offspring vitality, afterbirth delay, severe diseases of genital organs, no heating. Lately, the import of pig population to Ukraine has become more active. In 2009, the population of Large White pigs was imported from Hungary to Nikolaevsk region that belongs to Northern Black sea coast territory. In relation to this, fertility-related traits were being examined in the sows of the population through the entire three generations. The results of the examinations conducted testify to the effects of Hungarian breeding sows’ adaptation to Black sea coast territory for their fertility-related traits which decreased with their first farrowing. The animals of the first generation showed the poorest indexes as compared to the acclimatizer-generations. The first generation animals are marked to decrease plural pregnancy by 0.52 fetuses as compared to the acclimatizer-generations. Each of the subsequent generations manifested decreased variability of all the traits examined, but increased plural pregnancy in the sows of the second and third generations by 0.23 and 0.82 fetuses, respectively. The first generation animals are marked to have maximal number of stillbirths, but this index becomes lower with each subsequent generation during the adaptation. Herewith, the difference in this index is true for the first farrow-sows of the third generation versus the acclimatizer-animals. The similar tendency is observed in age-mature sows tested for the results of two and more farrows. This testifies to consolidated animals of the population for the indexes examined in the course of adaptation.

Abstract
The paper presents major research data about curds production based on soya milk with the culture of Lactobacterium helveticum, Streptococcus salivarius involved. The soya curds, whatever way they could have been produced, are tasteless, their protein content twice exceeding milk curds though. To add the flavor to the pressed freshly made soya curds different spices of pepper, garlic, boiled vegetable water are supplemented. Soya cheese tofu is just a mere pressed soya curds. Lately, the tendency to expand utilization of non-costly soya protein has been great in world economy. At the present time, only 10 % of the soya cropping is used as the indirect source of protein at the international market. With people’s suffering allergy and congenital intolerance to proteins, particularly milk and grain crop proteins, soya stuffs are today’s sole alternative to them. Soya stuffs can substitute ordinary milk in the nutrition of people with congenital intolerance to lactose as well as diversify the diet for those with allergic response to milk and eggs. With respect to food, soya protein is easily digested, high nutritious, sufficiently balanced for amino acid composition. As for biological value, it can be compared to the proteins of milk, fish and beef. Besides, soya stuffs do not contain cholesterol.

Abstract
The paper provides the pattern to produce modern mini-pigs which were created on the basis of mixers (Large White x Svetlogorsk mini-pig) in the 90s of the 20th century. CD RAS CGI diminutive pigs are considerably different from small laboratory pigs for molecular- and immune genetic markers and stud breeds for H-FABP НН genotype frequency, the carriers of the genotype involved being 36.1-57.1 % less than those of stud breeds. H-FABP hh homozygous genotype is revealed in a third of the diminutive animals whereas such animals rarely occur in stud breeds. The pigs of the population examined are liberated from mutation in RYR-1 gene, i. e. genetically, they are stress resistant. 76.2 % of animals have GG genotype of ECR F18/FUT1 locus. In leptin locus, ТТ and СТgenotype occurs in 45.7-46.7 % of individuals, but CC genotype does in 7.6 %. Bb allele with 0.117frequency is revealed in the animals of the modern population of diminutive pigs that has never occurred either in the population or in different stud breeds. The frequency of EAE aeg allele decreased by 0.29, but that of EAE bdg allele increased by 0.333 versus the year 2001. Genetic similarity index between the populations of 2001 and 2013 was within 0.990. Regarding the genetic structure of blood groups, SD RAS CGI diminutive pigs are closer to Svetlogorsk mini-pigs, mini-sibs and Vietnam Black breed and more distant from the stud breeds: Large White and Landrace. The genetic similarity index of the modern diminutive pigs with Svetlogorsk ones makes up 0.925, with mini-sibs - 0.938, Vietnam Blacks - 0.930; as for Landraces and Large Whites, it is 0.905 and 0.911, respectively.

Abstract
One of the biologic characteristics in pigs housing is the arrangement of «lavatory» in a strictly certain place where it is wet, dark, but what is most important there must be the possibility to contact other animals from the neighboring stalls. The examinations showed that defecation places designated and the lateral wall made next to the automatic drinking trough encouraged fewer defecations in the first zone (lair) in the experimental group as compared to the control. This was observed in the first three days of monitoring. It was established that in the first zone, the second and third experimental groups defecated by 2.38 and 4.2 % less in number; in the second (feeding) zone, they did it by 6.6 and 15.5 less, but it was otherwise in the third (defecation) zone where they defecated by 8.3 and 19.7 % more. Ten days later, the amount of animal wastes in the first stall did not change notably. The highest number of defecations was observed in the second (58.9 %) and third (30.5 %) zones. No defecation was marked in the second stall in its first zone; as for the second zone, defecations made up 16.2 %, but the third zone was noted to have the highest number of defecations (83.2 %). The analogous regulation was marked in the third stall. No defecations were found in its first zone, in the second one they were 10.5 % and in the third - 89.5 %. The defecation places designated and the lateral wall of the stall made next to the automatic drinking trough also allowed to decrease aggression responses in pigs in the second zone by 33 and 60 %, in the third - by 75 and 100 %, respectively.

Abstract
To increase the efficiency of agricultural production is one of the most important problems which solution discloses further possibilities to intensify the rates of its advance and food supply for the country. Economic efficiency shows the final beneficial effect of production means and live labor applied and reward from summarized inputs. Increased economic efficiency in production facilitates the growth of production and rural population’s incomes, social conditions improvement. One of the priority ways to increase the agricultural production efficiency is to decrease labor-, stock- and fund consumption in production, to update specialization and consolidate production concentration, to arrange labor and introduce resource- and energy-saving technologies. An important aspect of energy saving in crop production is to involve crops, which are intended to be used as biofuel into crop rotation. The crop may be rape which oil is an alternative to diesel fuel; it is widely spread as fuel for machine-tractor aggregates.

Abstract
The work considers the problems to select a mobile mixer-distributor regarding the conditions of a farm. It also determines technical and technological factors which effects on the time for a single feeding procedure with a mobile mixer-distributor are the greatest. The graph of mobile mixer-distributor conditions is examined in the process of making and distributing feed mixtures on a dairy cattle farm. There are the data on computer modeling of the time for a single feeding procedure with a mobile mixer-distributor taking into account the likely character of time balance constituents and different conditions of the distributor performance. The paper estimates the effect of mixer-distributor performance conditions on the time for a single feeding procedure. It is identified that to purchase mixer-distributors with lifting power over 10,000 kg is not reasonable even for high livestock population; to increase the norm of feed mixtures distribution does not result in the same increase in the time for feeding. Every 100 m increase in the average distance between feed storage houses accounts for 10 % increase averaged over the time for a single feeding procedure. Such parameters as the time to cope with technical refuse, collecting the data on the technological disturbance and the time to do away with the technological disturbance influence the likely time for a single feeding procedure within the limits from7 to 10 %.

Abstract
The work provides theoretical foundation for determining the conditional viscosity of paint and varnish materials as well as other Newton liquids without time-factor accounted. Conditional viscosity determined with the technique proposed depends on the amount of liquid forced out into the measuring capillary of a viscometer. There are two viscometer constructs presented determining conditional viscosity with the technique. The device to measure viscosity allows to determine conditional viscosity of a liquid medium due to the fact that the liquid medium of a certain volume to examine is placed in a principle vessel connected with the measuring vessel through the system of pipes with free outlets. The conditional viscosity of the liquid medium examined is determined by the amount of the liquid forced out into the measuring vessel. The viscometer, that has a spring as a working element, cylinder capacity, measuring capillary, valve, piston rod and the piston, allows to determine conditional viscosity of the liquid examined for its amount forced out into the measuring capillary by the expense of the vacuum created by the piston exposed to the spring. The designed devices shall allow to increase the accuracies of measurements as well as the quality of materials preparation and works performed.
