Spring wheat is considered to be one of the most important crops. The authors focus on relation between variety genotypes and environmental conditions as it is of great importance both for selecting new highly productive varieties and development of modern technologies of spring wheat cultivating in concrete climatic zone. The paper aims at studying influence of the weather on the crop yield and quality of spring wheat in intensive farming of Novosibirsk Ob forest-steppe zone. The experiments were carried out at on-the farm conditions of Irmen stud farm (Ordynskii district, Novosibirsk region) in 2014-2016. The authors estimate the crop yield and quality of spring wheat of different ripening groups in conditions of traditional and intensive farming. The paper shows that intensive technology cultivating resulted in increasing maximum and average leaf surface of spring wheat. The data of Novosibirskaya 31 variety varied in dependence on year conditions. The authors found out that intensive farming technology increased crop yield on 35.1- 41.7 % of mid-early ripening variety Novosibirskaya 31 and on 37.4 - 55.3% of mid-ripening variety Novosibirskaya 18. Intensive technology increased economic indicators whereas it varied in dependence of year conditions. The part of year conditions influence on crop yield and economic indicators was lower than the part of genotype influence and technology of cultivating.

Adaptability and resistance of potato varieties define potato productivity, quality and efficiency of its cultivating. The authors investigated the potato varieties of Moscow and Belarus selections and compared them with local varieties. The researchers found out that potato varieties resistant to weather conditions are highly productive. These varieties are selected in Siberian Research Institute of Plant Production and Selection, Kemerovo Research Institute of Agriculture and Siberian Research Institute of peat. The authors observed the highest productivity of theses varieties: 0.928 g pro a plant, bulb size - 80.0 g and high marketable value due to low number of bad bulbs. The varieties of Belarus selection were less adaptable and produced lower crop yield: 0.846 g pro a plant, low mass of a bulb and big number of bad bulbs. The same was observed in respect to resistance to Y-virus. Viral plants reduced the crop yield of bulbs on 112 g in Siberian varieties; 176 g - in Moscow varieties and 293 g - in Belarus varieties whereas the number of bulbs was reduces on 2.3, 0.2 and 3.8 correspondently. Moreover, the authors observed increasing number of bad bulbs in Belarus potato varieties. Thus, there were about 50% of bad bulbs observed in Belarus varieties and 18% in Siberian varieties. The authors outline that Siberian crop breeders should focus on breeding the genotypes resistant to viral pathogens, especially to potato virus Y (PVY). This disease is widely spread and destructive. Therefore, it is necessary to cultivate potato varieties that are adaptable to local climate and conditions in the cultivating area.

P. × jrtyschensis is widely-spread natural hybrid in geographic ranges P. laurifolia Ledeb. and P. nigra L. in Altai-Sayany highlands. In the basin of Tom it is observed sporadically in mixed timber stands of parental generations. Sometimes, it makes populations of hybrid habitual area appeared due to natural and anthropogenic factors. The first ones appear in the bottomland as a result of catastrophes caused by river-bed evolution. In some years, snow and icy floods result in destruction of vegetative ground cover and therefore natural hybrid populations. Their origin is cyclic and relates to hydrological water regimes. Anthropogenic populations appear within and outside the bottomland due to human economic activity that results in destruction of vegetative ground cover. Population age that is defined by means of the number of rings on tree trunks, doesn’t allow to date poplar planting on the sediments situated near a river channel. It defines the time when its growth is getting from bushy to tree one. It also shows that in spite of annual poplar bearing, the conditions for successful mass colonization of the sediments situated near a river channel appear approximately once every 10 years in the basin of Tom. The age of hybrids in natural populations exceeds 30 years whereas their number is reducing. This reflects the effect of natural selection in natural conditions that results in elimination of hybrids as they cannot compete with parental varieties. Variation of morphometric parameters of P. × jrtyschensis leaves in natural conditions is not high in spite of dominance of intermediary forms as they are closer to one of the parents. In anthropogenic populations selection impact is low, variation is higher, forms are of different age and quality according to morphology of leaves. Therefore anthropogenic hybrid areas are significant for selecting valuable forms of spontaneous hybrids. In natural and anthropogenic populations, hybrids turn to the P. laurifoli side.

The research was carried out in 1986-2016 on leached chernozem of Ob forest-steppe in multi-factor stationary field experiment in Siberian Research Institute of Farming and Chemicalization. From 1981 to 1990 the crops were cultivated in 5 crop rotation: “steam-winter wheat-wheat-barley-wheat”; in 1991-2006 this experiment was rearranged in 4-crop rotation “steam-winter wheat-wheat-wheat” ; since 2007 winter wheat was replaced by wheat: steam - wheat - wheat - wheat”. The variants of machinery tillage were as follows: 1) tillage in the steam on 25-27 sm, under the wheat (the second and third crops after steam) on 20-22 sm; 2) nonmouldboard cultivation by the stands of Siberian Institute of Mechanization and Electrification in the steam on 25-27 sm, under the wheat on 20-22 sm; 3) minimum tillage by Stepnyak cultivator on the depth 10-12 sm under all crops; 4) without fall tillage. Grain dockage was investigated by means of two chemical backgrounds: extensive and intensive ones. The authors make case that minimum soil tillage under the crops with no plant protection means enhanced grain dockage 1.4-1.8 times; no fall tillage enhanced grain dockage in 2.3 times in comparison with ploughing. The researchers observed spreading of perennial weeds in spring wheat: corn bindweed, yellow thistle and field milk thistle. The authors outline that changes in weed species in grain and steam crop rotation relates to minimum soil tillage and climate conditions as well. Climate warming in Western Siberia on 1.330 С resulted in the origin of such weeds as common fumitory, prostrate amaranth, goose grass and Mexican tea. The paper shows high effect of modern herbicides (Puma-super, low-volatile ester 2-D) in preventing weeds spreading. Application of plant protection complex on the intensive background influenced positively and the number of weeds in grain and steam crop rotation was not harmful in all variants of soil tillage. Cogeneration steam is considered to be one of the most efficient way to reduce the number of perennial weeds as it combines 2 mechanical cultivations on the depth 6-8 sm and 2 herbicide tillage with system specimens.

Seven species of dicotyledonous plants selected for their ability to accumulate high levels of total soluble protein in vegetative tissues were introduced into in vitro culture. To obtain an intensively growing loose callus, suitable for the preparation of a suspension culture, nutrient media compositions were optimized and the morphogenetic reactions of various types of explants were evaluated. After screening for the ability of callus formation of seven species of dicotyledonous plants, it was established that fast-growing suspension lines can be obtained for the cells of three plant species - Nicotiana tabacum, Daucus сarota, Amaranthus hypochondriacus, using the noted protocols of media and explant types. Based on the evaluation of the growth characteristics of the suspension cultures obtained from the calli of the three isolated plant species, it was established that all three cell lines analyzed were characterized by high viability and intensive biomass increment. The results of a comparative analysis of the growth of biomass in the three analyzed cell cultures revealed that the cell density increased most in the suspension culture of A. hypochondriacus. Using the reporter gfp-gene, the selected cell lines were evaluated for their ability to accumulate a recombinant protein. A direct correlation was observed between the accumulation of total soluble and recombinant proteins in the cells of the suspension culture. Cell cultures obtained on the basis of these plant species are of interest for biotechnology and will be used to create production lines for recombinant proteins, including medicinal products.

Aggression of water vole males (Arvicola amphibious L., Rodentia, Cricetinae) depends on the season and the number of populations. The impact caused by ontogenetic factors in aggressive behavior is not investigated. The authors explored the influence of conditions of early post-natal development on aggressive behavior of water vole males and the tendency to social dominance in the conditions of the Institute of Systematics and Ecology of Animals SD RAS . The researchers used dyad tests of 5-30 minutes for the experiment. The authors outline that there is no proof in scientific literature about the essence of any test duration. It is necessary for planning the experiment and design the test. The researchers placed water vole males in the space of 50 sm and recorded them during 10 minutes in order to register their behavior. They assessed aggressive and positive behavior of the animals in both parts of the experiment in order to define the appropriate test duration that would be sufficient for defining the degree of aggression and social rank of the animals. The authors observed positive correlation between animals’ behavior in first 5 and 10 minutes of the test. The authors make conclusion that data received in first 5 minutes of the test is sufficient for assessment of individual behavior of males’ interaction. The analysis results about the tendency of the water vole males to social dominance have shown that higher litter contributes to higher number of dominant males.

The paper describe the experiments in studying the impact of growing medium components on feed preferences of Galleria mellonella larvae. The researchers used the methods of mathematical planning of the experiment. The research group carried out the linear plan 29-5 for calculating the coefficients of regression equation taking into account compensation of spatial scattering factor. The experiments were carried out in the same manner in order to reduce dispersion and increase statistical significance of regression equation coefficients. The authors found out the regularity of average density of feed larvae. The average concentration of larvae was rather less in the centre than in the edges of content. Larvae concentration influences their position in the content as their number is much higher than their impact of variation ( ±10%) in the feed composition. The paper suggests 4 hypotheses of choosing the approximating function: hypothesis of average level; median hypothesis; factor hypothesis, that enhances larvae concentration on the edges; and hypothesis of reducing concentration of larvae in the centre of the content. On the basis of the hypotheses the authors define reference level and calculate experimental data for reducing the experiment dispersion. The researchers provided piecewise line approximation of experimental results and calculated compensation coefficients. Minimum sum of squared deviations was used as a criterion of choosing hypotheses. The appropriate hypothesis assumed the factor which enhances larvae concentration on the edges along the axial axis of the content where the larvae were grown. The concentration of larvae on the edges was 2.15 times higher in comparison with that in the centre; experiment dispersion was 3.7 reduced as a result of recalculation. This speaks about the significance of impact produced by spatial distribution of larvae concentration.

Application of promoter sites that provide tissue-specific expression of transgenes, allows accumulating foreign proteins in target tissues. This reduces the risk of bad influence on plants, human and environment. Otherwise, high-specific promoter sites often loose or change their specificity when being transferred to new genetic environment that requires beforehand checking of their expressive effect in transgenic plants by means of reporter genes. The paper aims at evaluating the nature and efficiency of reporter gene uidA expression when being managed by promoter sites of Arabidopsis thaliana, apеtala3 and rpt2a genes and transferring to genome Nicotiana tabacum. Gene apеtala3 is expressed in flower meristems and codes transcription factor of В group, which regulates flower development. Gene rpt2a codes 19S regulatory subunit 26S of proteasome and it is expressed in apical meristems of root and stalk mainly.The article shows that promoter sites of the genes provide tissue-specific expression of reporter gene uidA in conditions of allogeneic genome. The authors observed ectopical expression of transgene in relation to the type of promoter site used. This expression is restricted by meristem areas in the organs of transgenic plants. Comparative analysis of testing results on kanamycin resistance and hystochemical analysis has shown that GUS-coloring intensity was higher in derivatives of tabacco transformants, which carry two and more insertions of transgene in the genome. This speaks about possible additive effect of transgene insertions number that enhances expression and accumulation of reporter gene product in the tissues of transgene tabacco plants.

The authors outline that blood composition is a motile internal environment. Its hematological and biochemical parameters are changed in relation to animal genotype, age, sex, feeding conditions and keeping. The authors investigated concentration of macroelements in the blood serum of Black-and-White calves aged 18 months. The researchers selected blood serum from 26 healthy animals and defined biochemical and hematological parameters in the laboratory at the Chair of Veterinary Genetics and Biotechnology at Novosibirsk State Agrarian University. The authors used photometer 5010 and standard methods of blood inspection. The research found out that the basic parameters varied within the standard. Increase of calcium concentration in the blood. There is no much information in scientific resources about relation between macroelements and hematological and biochemical parameters. The paper explores relations between macroelements accumulation in the organs and blood parameters. The average data on concentration of macroelements in the blood serum should be considered as a tentative standard for Black-and-White calves aged 1.5 year in Western Siberia. The researchers received positive and negative relations of macroelements in the blood serum. They revealed some correlations that can contribute to studying biochemical status of organism. The authors speak about interspecies differences that certify the role of heritance in the number of some macroelements in the organism.

The paper explores hystomorphological peculiarities of thymus structure of newborn American minks of Standard (+/+ +/+), Sapphire (а/а р/р) and Lavender (a/a m/m) genotypes. The authors found out that minks aged 1 day have formed thymus, parenchyme of cones is divided into cortical and renal medulla. The authors observed clear cortical and medullary ration in Lavender minks and poor demarcation in Standard and Sapphire minks. Maximum parameters of relative and absolute mass of the thymus were observed in Standard minks and minimum parameters - in Sapphire minks. The sectional area of cones in the thymus of Lavender minks was higher in comparison with other groups (187516.50±20972.67 mkm2). The sectional area of cones in the thymus of Standard and Sapphire minks didn’t vary greatly and it was 111941.40±13262.30 and 114024.20±17013.83 mkm2. The authors observed wider space of cortical substance in Lavender minks in comparison with this parameter in Standard and Sapphire minks. Cortical/medullary ratio of Sapphire minks has the lowest ration 4.60±0.38 and reaches its maximum in Lavender minks - 7.57±0.85. Hassal’s bodies were observed not in all cones; they are seen as single-cell and simple forms whereas multicellular amylaceous corpuscles are rarely observed.

The changes of hematological parameters and titer antiviral antibodies at BLV-infective calfs after introduction Ivermec are analysed. At infected at virus leukemia calfs, reacting in reaction immunodiffusion are occurred authentic decrease in quantity of leukocytes and lymphocytosis in blood (Р < 0,05), reaching the maximum for 7th day after preparation introduction. Thus the quantity neutrophilia for 3-7th days (Р < 0,05) simultaneously has authentically raised. By 14th day of supervision indicators have returned to reference values before preparation introduction. At not reacting in reaction immunodiffusion calfs after introduction Ivermec similar changes were smoothed and doubtful. At control reacting and not reacting in reaction immunodiffusion calfs which did not enter Ivermec, authentic changes in hematological parameters it is not revealed. The tendency to some decrease in a caption of antibodies to a virus leukemia in reaction immunodiffusion at infected calfs for all period of supervision till 28th day after introduction Ivermec (to 3,75 log2) is noted. At control infected calfs, reacting in reaction immunodiffusion whom did not enter Ivermec, a caption of antibodies to a virus leukemia was a little above (to 5,00 log2; P > 0,05). Taking into account the revealed changes in blood calfs after introduction Ivermec following recommendations to terms of carrying out of diagnostic laboratory researches on leukemia a horned cattle are offered. After introduction Ivermec carrying out hematological researches at horned cattle on leukemia should be begun not earlier than in 14 days. Carrying out serological researches at horned cattle in reaction immunodiffusion on leukemia should be begun not earlier than through for month after introduction Ivermec, because of possible decrease in a caption of antibodies and appearance of false negative reactions.

The paper explores the impact of immunoamplifier ImmuGuard on the basic immune biological parameters of Ross 308 broiler chickens blood. Innovative specimen ImmuGuard is developed by means of combination of fermentation of selected strains Saccharomyces cerevisiae and fructo-oligosaccharides by foreign company MicronBio-Systems. This specimen improves immunity, gastroenteric tract, condition and productivity of animals. The experiment was carried out in the housing room of Omsk Agrarian University and at the laboratory of Research Institute of Animal Science. The researchers arranged 2 experimental groups and a control group. Each group contained 30 animals. The conditions of housing, feeding and watering of poultry were the same for all the groups. The animals had free access to feeds and water. The authors applied immunoamplifier ImmuGuard dosed 150 g/t of water for the 1st group and 250 g/t of water for the 2nd group during 18 days from the moment of hatching. The 3rd group was a control one. The researcher collected blood samples on the 20th and 40th days. The results show positive impact of the specimen on biochemical parameters and immune status of broiler chickens. Positive impact was observed in more intensive metabolism, larger number leucocytes, T-lymphocytes, cytotoxic T-lymphocytes and B-lymphocytes. The authors also speak about lower concentration of immune complexes in the blood serum of broiler chickens despite the application scheme of the specimen.

The results of many-years research speak about the impact caused by probiotic specimens based on Bacillus subtilis on the animals. The authors declare that including probiotics in raising young cattle is the most effective and promising way to stay healthy and prevent diseases. This way is based ecologically free mechanisms of supporting colonization resistance of intestine. The authors investigated biologically active additive Vetom 4.24 that contains aerobic sporogenous bacillus Bacillus amyloliquefaciens strain VKPM V-10643 (DSM 24615). The research aims at studying the efficiency of preventive application of microbiological specimen vetom 4.24 for newborn calves. The researchers arranged 2 experimental and a control group and each group contained 5 animals. The calves from the 1st experimental group received the specimen twice a day in the morning and in the evening during 15 days. The calves from the 2nd experimental group received Vetom 4.24 twice a day in a day 15 prescriptions. The calves from the control group didn’t receive the specimen. The research shows that the specimen is adjusted to newborn calves physiology. The changes of investigated parameters varied within physiological capacities of the organism. Absolute body weight, relative and daily average body weight gain in the early postnatal period are increasing when applying vetom 4.24. The effective scheme of vetom 4.24 application is daily application during 15 days. The parameters of calves from the 1st experimental group exceeded those of the 2nd group on absolute body weight, daily average body weight gain and relative growth speed. The researchers didn’t observe any side effects when applying vetom 4.24.

The paper explores the impact of vetom 3.22 and vetom 3 on livestock measuring and body weight of Orel roadster weaning colts. The research results were assessed after finishing the period of application of the specimen and in 6 months. Vetom 3.22 and vetom 3 increased height at the withers, body length, chest girt, metacarpus girt and absolute body weight. Exterior parameters of colts when applying vetom 3.22 and vetom 3 increase in the period of application and during 6 months after. The specimens didn’t affect the colts condition. During application of the specimen the researchers observed increasing of height at the withers on 1.76-2.58%, body length on 0.10-24.56%, chest girt on 0.10 - 3.94%, metacarpus girt on 0.43 -5.36% and absolute body weight on 2.49-6.35%. In 6 months after finishing the application of the specimen, livestock measurements were definitely higher than that of the control group on height at the withers of thew colts from 1st, 3rd and 5th group, body length - 2nd, 3rd and 5th groups, chest girt-2nd, 4th and 5th group; metacarpus girt - 5th and 6th group and absolute body weight - 1st, 4th and 5th groups. The authors observed the highest exterior parameters in the colts of the 5th group where vetom 3.22 dosed 1 mkl/kg was applied. The positive impact depended on the explored specimen, dose and application scheme. Maximum increase of all livestock parameters was observed when applying the specimen dosed 1 mkl/kg of mass once a day, 5 days and then in a day 9 times. The specimen is liquid. The probiotics improve sport capacities of colts as there is a relation among height at the withers, wide chest and speed of a horse.

The paper studies hepatoprotective effect of new injection hepatoprotective specimen liquirol on the model of severe toxic experimental tetrachlormethane hepatitis of rats. The authors found out that liquerol has pharmaceutical and therapeutic effect when tetrachloromethane affects the liver. This is proved by better condition of tested rats and morphofunctional condition of their liver. Applying the specimen, the authors observed reducing of cytolytic and cholestatic syndromes, improving of metabolism that reduces the effect of aspartate aminotransferase on 24.0%, glutamyl pyruvic transaminase on 33.9% , alkaline phosphatase in 1.2, gamma-glutamiltrans-peptidase in 1.1, cholesterine in 1.6 and total bilirubin in 1.45 times; crude protein increased on 24.8%. Liquerol enhances inhibiting of lipid peroxidation and increases capacities of endogenous antioxidative system. The number of dien conjugates reduces in 2.15 times, ketodien number reduces in 1.67 time, and malondialdehyde - 1.36 time. The level of midmoleculepeptides reduces in 2.38 times that confirms the effect of treatment.

The paper explores the results of observing and testing 70 animals of german Black-and-White cattle and reveals different diseases of displaced abomasum (Dislocatio abomasi sinistra et dextra). The researcher uses BCS method and studies the condition of cows with displaced abomasum in relation to feed consumption and duration of pre-clinical period. The paper analyzes cases of displaced abomasum and describes the results by means of total population of suffering cows and specific experimental groups formed according to the features of sex cycle current period. Total population revealed lower condition of moderate degree (µBCS was 2.7 points) in comparison with average parameters of appropriate degree and permissible range for condition in dairy cattle breeding. The author speaks about the highest and lowest values in total population: only 4% of total population cows had BCS condition according to one of extremum and showed the features of fattening (4.0 points of two animals) or attenuation (2.0 points of 1 animal). Moderate reducing of condition was observed in 4 experimental groups: AMBCS - 2.8; 2.8; 2.6; 2.4 points. The most evident reducing of condition of cows with displaced abomasum was observed in the pregnancy period of (1 experimental group) and post-calving period (2 experimental group). The author speaks that the lower reducing of condition was observed n cows with right displaced abomasum in comparison with left displaced abomasum (AMBCS - 2.6 vs. 2.8 points). Condition in nosology and diagnostics of left and right pathologies of abomasum should be considered as a factor of these pathologies but not the reason.

Tadzhikistan has great capacities for increasing of fish yileds in the basins (lakes, rivers, basins and irrigation channels). The climate has patchiness and includes many climatic zones. The research was carried out in Gissarskaya valley in the zone with sharply continental climate. The main restrictive factor that prevents the growth of fish yield is low pond productivity and weak aspects of growing technology. When growing wish, it is necessary to take into account climatic zones as each climatic zone has its own thermal constants and duration of vegetative season. The research explores the influence of different fertilizers doses on the fish capacity of ponds and efficiency of growing herbivorous fish in the polyculture with application of pelleted feeds. The authors speak about efficiency of fertilizing ponds with nitrogen and phosphorus fertilizers and organic matter when growing grass carp and silver carp in the polyculture with a carp. This gives possibility to use efficiently the food reserves of ponds and increase their fish capacity. Carp livability was 86% in the period of growing; grass carp - 90 % and silver carp - 83%; average fish mass in the end of the experiment was 874, 3419 and 1426 g; daily average body weight was 4.1, 16.3 and 6.8 g; total fish capacity was 19.61 c/ha.

The research was carried out at pig complex (Melekesskiy district of Ulyanovsk region) and investigated efficiency of sorbing probiotic additive Bisolbi when feeding pigs, growing and fattening. Biospecimen consists of mineral siliciferous powder and probiotic bacteria Bacillus subtilis. Its Biospecimen dosed 0.5 and 1.0% of feedstuff changes the direction of metabolism, improves protein synthesis and increases daily average body weight on 4.94 and 9.19%; it increases pig maturity when their body weight is 100 kg on 8 and 19.9 days and reduces feed consumption pro 1 kg of body weight on 0.8 and 1.48. Fattened pigs of experimental groups have more intensive growth of the carcass (on 1.50-2.00 sm) and body weight (on 0.50-2.01 %), fat depth is reduced on 3.00-5.00 mm, loin eye area is increased on 1.62-6.69%, meat composition on 2.71-6.00 %, Р<0.05), output of the fat, bones and tendons reduces on 3.83-4.70 (Р<0.05) and on 0.92-2.65 % correspondently. Concentration of dry substance in the meat increases by means of protein (to 20.37-21.09 %). Application of feeding additive Bisolbi enhances qualitative and quantitative parameters of meat production, reduces feed costs pro body weight gain, fattening period on 8-19.9 days and increases profitability of pork production up to 18.43-20.62%. All changes mentioned above are mostly observed when feeding pigs with sorbing probiotic Bisolbi dosed 1.0%.

The paper explores the data of economic experiments on applying betonites as a source of macro- and microelements in feeding young poultry. The object of research was betonites at 10th Khutor area of the Republic of Khakassia, turkey poults of Hybrid cross and Hubbard ISA F15 cross broiler chickens. The researchers arranged a control group and three experimental ones of turkey poults, and a control group and five experimental ones of broiler chickens. The researchers applied betonites dosed 1-3% in feeding turkey poults instead of the main feedstuff; 1-4% of betonites as an additive to the feedstuff when feeding broiler chickens; 5th experimental group had free access to betonites. Due to mineral elements and adsorption properties, betonites influenced positively young poultry growth, its livability and meat quality. Betonites dosed 2% increased body weight of turkey on 23.9%, turkey poults - on 7.6 %, and broiler chickens - on 5.0 %. At the same time the authors observed 100 % poultry livability, slaughter yield increase on 2.9; 10.4 and 1.8% correspondently. Meat nutritional value has increased according to meat and meat-and-bone indexes. Application of betonites as a mineral feeding additive in the organism of turkey poults and broiler chickens contributed to better phosphoric and calcium metabolism. The lack of ketone bodies in the poultry blood speaks about good protein and lipid metabolism. Bentonites dosed 2% provide higher profitability of poultry meat: 46.6% when growing turkeys, 37.7 - turkey males and 32.7% - broiler chickens.

The paper explores the impact of probiotic «Biological feed complex” on fertility of broilers. The research results show that application of biological feed complex enhances the growth and development of broilers during the research period. Since 14 days, age body weight in the experimental group is increasing in comparison with that in control group. This tendency was observed up to the end of the experiment. Body weight of broilers aged 21 days was 3.3% higher than that of control group (Р<0.05-0.001); body weight of broilers aged 28 days was higher than in the control group on 3.5%; aged 35 days - 5.8 (Р<0.05-0.001), aged 42 days - on 11% (Р<0.05-0.001). This effect is explained by positive influence of microorganisms that biological feed complex contains; it influences broilers’ flora intestine. The highest livability of broilers in the experimental group (97.5%) makes case that supporting microbiocenosis in the poultry organism by means of probiotics increases its immune status and prevents infections. Absolute growth of broilers from both groups was equal. According to this parameter, experimental broilers mostly surpassed their counterparts on the fifth week when difference was 18.8% and 15.7% on the sixth week. Application of biological feed complex for broilers aged 1 day and until the slaughter enhanced digestibility and nutrient availability of feeds. The authors outline positive influence of biological feed complex on blood biochemical parameters, better metabolism of broilers and morphological composition of carcasses.

The paper explores the existing approaches to classification of rural areas; it reveals the specific of rural areas and inappropriate suggestions on improving labour resources of rural areas. The authors classify the regions by means of cluster analysis which considers the degree of agricultural development, its specialization, situation in social and labour spheres of rural areas. The authors choose 3 most typical regions in each cluster. The author uses content analysis for exploring the content of legal regulations and standards at the regional level. These documents regulate rural development. The authors analyse the content of the document whether they are in line with Federal Target Programme «Sustainable development of rural areas in 2014-2017 and to 2020”. The results of content analysis assess the extent of concrete aims, tasks and measures in regional documents, make comparative analysis of program quality and reveal differences in programs quality in respect to clusters. Implementation of regional programs aimed at making comfort conditions for living in rural areas is characterized by means of financial support for program measures pro a rural person. The authors range clusters and regions that shows evaluation of documents content that specifies sustainable development of rural areas and extent of using state support. The paper makes conclusion about similarities in the sphere of regulation of rural development in frames of clusters and reserves for improvement of situation in the regions.

The paper analyzes development of logistics in Novosibirsk region in the aspects of fulfillment of agricultural producers’ needs in transport service. The authors analyze development of road system and indicators of transport complex development in the region. The authors found out that road system has increased in the period 2010-2015 in 1.9 times and hard-top roads - on 7862 km. The article shows statistical relation between transport complex and economic indicators of agricultural production. Correlation coefficient was 0.85 that speaks about close relation between these parameters. The analysis of scientific literature has shown that the auto transport is the main kind of transport for agricultural production. This transport has some advantages including “house-house” cargo delivery, high mobility and flexibility, possibility of using different routes and cargo delivery, possibility of different cargo size and wide range of choosing shipping carriers. Correlation coefficient between cargo size by cars and costs of agricultural producers work is 0.45, which speaks about imperfection of logistic market and its non-availability to suggest qualitative transport support for agriculture. The authors compare logistic development for agricultural production at the current moment and in the period of command-and-control economic system. The authors suggest the ways of logistic development in the region in order to improve the quality of logistics for agricultural production in Novosibirsk region.

The authors carry out agroenergetic and economic analysis of cultivating lucerne in the conditions of Privilyuysk (Nyurbinsk district) and Prilensk (olekminsk district) climate zones of Yakutia when applying different agrotechnological means: seed time and seeding rate. The analysis has shown that lucerne seeding on cryogenic soil in winter provides the highest profit and efficiency when cultivating lucerne for seeds and feeds. This profit and efficiency exceeded the control variant (spring period) on 28% and 30%; the efficient seeding rate is 1 kg/ha when growing for seeds (efficiency 72,6 %) and 8 kg/ha when growing for green mass (efficiency 126%). Lucerne sowing in the early spring provides the highest seed and feed productivity and maximum energetic coefficient (on seed sowings - 0.47; on feed sowings - 3.46) and economic efficiency (efficiency when cultivation for seeds was 89,4; when cultivating for feeds - 146%). The most efficient rates of sowing were 1 and 2 kg/ha when it is possible to reach the highest seed productivity of lucerne with energetic coefficient 0.51-0.52 and efficiency 81.5-78.5%. The authors declare that for feeds seeding rate should be 10 kg/ha in this climatic zone when it is possible to reach the highest parameters on energetic coefficient (2.91) and efficiency of production (126%).

Milk production in Russia and in Novosibirsk region is insufficient for efficient consumption rates by population. New technologies and breeding on increasing the productivity of dairy cattle breeding do not fulfil the necessity in producing milk due to reducing of dairy cattle. The capacities of dairy industry development and feed reserves are sufficient for rejecting from import of milk and even to export milk and dairy production.
