The purpose of research is the creation of apricot fruit varieties able sustainably fructify in the environment of forest-steppe of the Middle Volga Area. Experimental studies were carried out on the Cultivar Collector of Samara Research Institute of Horticulture and Medicinal Plants «Zhiguli Gardens» from 1985 to 2010. Since 2011up to present the work has been performed in a Samara State Agricultural Academy on the basis of horticultural farm Ltd. «Kutuluk» Bogatovskiy district. The objects of research were different varieties of apricot eco-geografic groups of selected forms of national selection and varieties bred in Samara Research Institute «Zhiguli gardens». The study, selection and transfer of hybrid seedlings to the state variety-testing were performed, under the methodology of selection and program of Cultivar study of fruit, berry and nut crops. As a result of long years of breeding under interkind hybridization in Samara Region 9 apricot varieties have been developed and transmitted to state variety-testing , 4 of which have been included into the State Register of the Russian Federation. In a period of organic resting the varieties are able without significant damage of the wood resist severe winters with a minimum temperatures at –39… –40°C. Favorable microzones for apricot cultivating have been identified, the yield, diseases resistance and technological qualities of fruit studied. As a result of 16 years of observations the apricot hasn’t fructified for 6 years. Because of the flower buds frozen in severe winters there was no yield 3 times, 3 times the harvest perished as a result of freezing of flower buds from frost occurred after long thaws. Variety differences of resistance to moniliosis shock were revealed. Such a resistance out of Samara region fruit the sort of Samara apricots has got. Samara apricots are smaller in size than any southern ones, but the biochemical composition and fruit taste compete to the latter.

The purpose is to justify the use of minimum and zero tillage in conditions of forest-steppe Zavolzhye region from the position of the biological activity of the soil. One of the factors forming and determining the fertility of the soil, is the activity of microorganisms that inhabit it, the active surface which reaches up to several hundred acres for 1 ha of surface topsoil. Important role in building of soil fertility is the number of major groups of microorganisms, which, being the catalysts of metabolism, objectively reflect the nature of biochemical processes. Another academician S. P. Kostychev (1937) pointed out that without the study of biodynamics the knowledge of the soil, especially from the agronomic point of view, may not be complete. Microorganisms occupy a key position in maintaining biochemical capacity of the soil, so monitoring of soil microflora is essential for the maintenance and reproduction of its fertility. This work is devoted to studying the role of soil microorganisms in the process of maintaining and reproduction of soil fertility in the development of new technologies in agriculture. The article presents data on the effect of basic tillage on the number of different groups of soil microorganisms (micromycetes, bacteria, actinomycetes), Shows the number of soil microorganisms, such as micromycetes (mold fungi) and bacteria are significantly influenced by seasonal changes in temperature and humidity than the soil treatment methods. From which it follows that the reduction of the mechanical load on the soil in the forest-steppe of Zavolzhye a significant impact on the number of major groups of microorganisms has not.

The purpose of the study is to increase the strength of the collected compounds and to expand the technological accuracy of the method of Assembly with an interference fit. Fixed press-fit connection with interference are widely used in machine building, when the transfer of substantial axial forces are required, torques or combined loads from their joint action. Resistance to mutual misalignment of the parts in these compounds is created and supported by the forces of elastic deformation on the mating surface of the covered part (shaft) and stretching on the mating surfaces of the covering parts (holes) is proportional to the magnitude of the preload in the connection. In such compounds, the diameter of the shaft before Assembly is always larger than the diameter of the hole. In the article the analysis of the known different ways of joining parts with interference fit, including hydraulic presses. The second problem is solved due to the fact that the connection details with tightness is carried out by pressing the press stroke from one detail to another, and the breakdown of the compounds obtained by the relative longitudinal movement of parts, in which the breakdown is carried out periodically in the process of pushing through the transfer of force from the press stroke to pressed items to the elastic connection. The force on the press stroke is created by a hydraulic cylinder with large displacement, a resilient connection between the slider and pressed item performs in the cylinder, the fluid pressure and volume which can be adjusted by changing the stiffness and capacity of the drive RAM, as well as the magnitude of its longitudinal movement during the disruption. The scheme of Assembly of the connection de-hoist with tension. Original technical solution for press fit connection parts extends the technological possibilities of the equipment, increases the strength of the collected compounds and can be used in machine building, particularly in mechanical Assembly processes and, in particular, in the repair and production of agricultural machinery.

The research objective is improving the mixing quality of the material and determination of structurally-kinematic parameters drum paddle mixer by means of numerical methods. The basis of modern society is the use of variety mixtures and composite materials on their basis. The preparation of the initial mixtures is carried out as directly by mixers, and in some cases by various devices, including extruders and screw presses. Among such devices drum mixers, dryers, mixers, etc are widely distributed. Their feature is the low intensity of mixing, as well as the ability for a relatively short period of time possible to achieve the uniformity of the mixture. Then the quality of the mixture practically does not change. Attempted use of commercially available cement- mixers of periodic action in order to prepare such a mixture as a feed, showed that their existing structures are subject to further improvement because of the impossibility of achieving zootechnical requirements for the preparation of feed on the basis of the purchase and BPD of their own forage. This requires additional theoretical research. The process of the blade drum interaction with the material operating with periodic mixing is shown. The obtained analytical expressions allow to determine the conditions of mixing of the material by major constructive and kinematic parameters of the lobed mixer drum on the basis of numerical methods.

The goal of the research is constructive adaptation of automotive diesel engines working by diesel mixed fuel. A perspective kind of an alternative motor fuel is biodiesel blend produced with mixing of vegetable oil and conventional diesel fuel in different percentages. The present diesel-powered machinery is not adapted to work on such kind of fuel because of the different properties of biodiesel and diesel fuels. Applying of the invented devices (such as dual-fuel supply system, the mixer-filter and ultrasonic fuel mixer) allows to adapt automotive diesel engines for work on biodiesel blend. The dual-fuel supply system performs engine start, warm-up and stop modes on mineral diesel fuel, and its work on biodiesel blend on other modes. The original design of the fuel mixer-filter provides effective mixing of components and filtration from contaminants. Due to the high frequency vibrations the ultrasonic mixer provides the obtaining of homogeneous fuel composition and molecular splitting of higher fatty acids contained in vegetable oil.

The purpose of the study is improving different body systems of animals in separate development phases of postnatal ontogenesis. To achieve this goal we studied the patterns of age-related changes of the activity of aspartate aminotransferase in the tissues of the duodenum of rabbits in different phases. Used rabbits breed gray giant at the age 1, 6, 12, 18, 24, 30, 45, 60, 90 and 120 days. The duodenum was divided into three parts: proximal, medial and distal. In every part of the duodenum was isolated two layers: mucous and muscle. In their studies of early postnatal life of rabbits was divided into phases. The studies show that due to changes in the structure and function of the muscular and mucous layers of the mucous membrane of the duodenum, due to changes in the composition and amount of food the activity of the enzyme varies. The activity of AST in the tissues of the mucous and muscle layers of the proximal, medial and distal parts of the duodenum at the age 1 day of rabbits in the colostrum nutrition phase, compared with other age groups, relatively low. In the first six days of life, in colostrum nutrition phase, the enzyme activity increases significantly. To twelve daily age rabbits, in the first dairy feeding phase, the activity of AST also increased significantly. Subsequently, the daily age of eighteen, in the second phase of dairy feeding, the activity of AST decreased significantly in the tissues of both layers ofthe proximal, medial and distal parts of the duodenum. Fromthedailyage of eighteen of rabbits in the tissues mucous layer of the proximal, medial and distal parts and in muscle layer of the distal part of the duodenum, the activity of AST is stabilized. In the muscle layer of the proximal and medial parts of the gut in subsequent phases of feeding rabbits the nature and intensity of age-related changes in activity of AST are slightly different. These distinctive features in the muscle layer of the mentioned parts of the duodenum, possibly associated with peculiarities of generation of their structure. Thus, the most intensive processes of transamination of aminoacids with the participation of aspartate aminotransferase in the examined tissues are seen in rabbits at early stages of postnatal period, toeighteendayold.

The purpose of the study is improvement of various in in animals body systems in separate development phases of postnatal ontogenesis. To achieve this goal, we have studied the regularities of age-related changes in the activity of gamma-glutamyl transferase in the tissues of the muscles biceps and triceps brachii, quadriceps femoris, gluteus and gastrocnemius muscles of the extremities in rabbits in different phases.Used gray giant breed rabbits at the age 1, 6, 12, 18, 24, 30, 45, 60, 90 and 120 days. Age groups were formed according to the principle of unique, taking into account gender, body weight, type of nervous system and general condition. The animal muscle tissue samples were removed and frozen in liquid nitrogen for further research. The activity of gamma glutamyl transferase was determined by photocolorimetric and spectrophotometric methods in the scientific laboratory of the Department of Agricultural Chemistry and Ecology of the Academy. The resalts show the nature of age-related changes of the enzyme levels in the tissues of the biceps and triceps the first forty-five days of life is about the same. But it should be noted that the increase or decrease intensity of GGT activity in the tissues during this lifetime differs. In the rest of the studied periods of life the nature of the activity of the enzyme in the biceps and shoulder triceps is different. The most intensive changes in the GGT level in the tissues of the biceps is detected from two-month to three-month age (increased 2.7 times, p<0.001) in the tissues of the triceps – from forty-five daily to two months (increased 3.9 times) and from three-months to four-months (increased 3.0 times, p<0.001). The character of changes of enzyme activity in the tissues of thigh quadriceps at different age rabbits differs from that of the rest of the studied muscles. The most intensive GGT activity changes from twenty-four to thirty days age (increased 4.0 times, p<0.001). Age-related changes in GGT level in the tissues of the gluteus and calf muscles are basically the same. The difference is found only in the first six days of rabbits` life. Enzyme level in rabbits in the tissues of the gluteus maximus during the first six days increased by 91.0%, p<0.05, and in the tissues of the calf muscle, it falls to 27.3%, p<0.05.

The purpose of research is beef production efficiensy growing of Black-Motley breed by use of natural drug Nukleopeptid. The research was carried out in SEC-farm «Hero» Chegmagushevskogo district of Bashkortostan. To carry out scientific and economic experience were formed 4 groups of Black-Motley breed calves at the age of 6 months, with 10 heads each. Groups were formed on the basis of analoge groups. The animals of the experimental group II had drug Nukleopeptid subcutaneously at dose of 20 ml, test group III – 25 ml and experimental group IV – 30 ml. The bulls of Group I is control and the drug is not administered them. In setting up the experience of the measurements of animals calves experimental groups had no significant differences in performance. Measurements of all groups of calves naturally increases with age. Studies have revealed that during the period of experience in the animals of group I height at the withers increased by 20.6%, height in the sacrum – by 17.9%, length of the body – by 38.4%, the depth of the chest – 37.3%, the width of the breast – 40.2%, putting backside – 25.5% femus width by 45.9%, whereas test groups in bulls (II-IV), these figures were above 0, respectively, 9-2.0; 0.5-1.4; 1.3-1.8; 0.1-1.0; 2.1-4.5; 1.8-3.6%. Indices body had the same trend. Gobies experimental groups, this applies especially to young animals of group III were more massive with well developed chest and back of the torso. It is proved that the introduction of new drug Nukleopeptid contributes to the meat productivity.

The purpose of research is heifers protein dairy raising of Holsteined Black-Motley cattle of Samara type. Studies on the identification of polymorphism and the definition of occurrence frequencies of alleles and genotypes at loci kappa-casein gene (CSN3), beta-lactoglobulin (LGB), and complex genotypes (LGB/CSN3) Holsteined Black-Motley breed cows of Samara type. It was established the influence of the genotypes of these genes for heifers dairy production. The cattle of CJSC «Lunacharsky» with genotype CSN3ВВ for dairy production during 305 days of lactation had an advantage over CSN3АА genotype at 348 kg and 468 kg in the CSN3АВ and butter fat content showed significant superiority to 0.16% (P˂0.001) and 0.23% (Р˂0,01). At the exit of butter fat and 28.1 to 23.9 kg of milk protein by 15.3 and 12.7 kg, respectively. The heifers of «Breeding Farm “Druzhba”» with these genotypes are equal. The heifers with genotype LGBВВ CJSC «Lunacharsky» had lower level to genotypes LGBАА, LGBАВ and the level of dairy production at 208 kg and 75 kg of milk. But had the advantage of butter fat content 0.08%, protein by 0.05-0.03%. The heifers of «Breeding Farm “Druzhba”» with the heterozygous genotype LGBАВ genotype produced significantly more at 478 kg (P<0,05) and 150 kg of milk compared with homozygous genotypes LGBВВ, LGBАА and that increased butter fat output 19.8 kg (P<0,05) and protein – 14.5 kg (P<0,05).
