Description
The article presents a study on agro-biological and technological indicators of Don indigenous wine grapes in the conditions of the Anapa-Taman area of the viticulture of the Krasnodar region. It was found that the introduced varieties are consistent with the conditions of the area and can be recommended for growing in production plantations in southern Russia. On ripening, the varieties are as follows: the early ripening varieties are Sibirkovy; a group of middle-ripening - Aligote, Plechistik, Varyushkin; to the medium-late - Bessergenevsky 10 and Krasnostop Anapsky. Highest yield was proved to for such grape varieties as Bessergenevsky 10 (150 kg / ha) and Varyushkin (140 kg / ha). Test grapes of Aligoté and Krasnostop Anapsky showed an average yield of 120 and 130 kg / ha, respectively, red and Sibirkovy Plechistik - 140 and 135 kg / ha. Comparing the current literature with the results, we noted the following notable differences: all the studied indigenous wine grapes in the conditions of the Anapa-Taman area of the Krasnodar region matured earlier, had higher productivity indexes and gave higher yields, than in the conditions of their homeland Rostov region

FOREST AMELIORATION OF SANDY SOILS OF TERSKO-KUMSKOYE INTERFLUVE PLAIN WITH PINE CULTURES
DescriptionThe article considers the regularities of the growth and development of the plantations of Crimean and Scotch pine on sandy soils of Tersko-Kumskoye interfluve plain, presents the classification of forest suitability, estimates the forest growing efficiency and prospects of the use of pine species when forest amelioration of soils, suggests the technologies for forestations arrangement. During the past century there had been grown over 60 hectares of pine cultures on sands of Tersko-Kumskoye interfluve plain under the strict conditions of transition zone dry steppe-semidesert. The Achikulakskaya NILOS VNIALMI (N. K. Lalymenko, V. I. Kabalaliyev, N. S. Zyuz) managed to plant about 60 hectares of Crimean pine and over 5 hectares of Scotch pine cultures in the 70-80-th of the last century, about 50 % of them are still growing. The study of the said forestations led to the following conclusions. On the thick sands (6-8 m) of Bazhigansky forest area the stable growth of Scotch pine continues up to 25-30 years, that of Crimean pine – up to 30-35 years. By the age of 40 the productivity of Crimean pine forestations (170-260 m3/ha) exceeds visibly the accumulated reserve of Scotch pine forest stand (60-100 m3/ha). The increment in height decreases sharply starting at the age of 15-20 years for Scotch pine and at 25-30 for Crimean pine plantations. On the clay sands with the level of low-mineralized ground water of 2,5-3,0 m and despite high fall the stable growth of Crimean pine continues up to 35-40 years and more. On the monophase sands of Tersky forest area the Crimean pine grows relatively slowly during the first 10-15 years though more evenly year by year. The thick lamellar deposits and monophase sands with the depth of sweet ground water of 3-5 m provide the best conditions for forest growing. The longevity of Scotch pine plantations of 50-55 years and that of Crimean pine of 60-65 years can be achieved by current planting technologies and effective conservation of the forestations on the thick sands, while on the medium thick clay sands it can be 60-65 and 70-75 correspondingly, and on the monophase sands on the sites with the additional life-long sweet ground water nutrition – over 80 years. The following measures should be the most effective when afforestation of highly overgrown sites – the many-year fallow and thorough cultivation of inter-rows of young cultures and their planting with coulisses and blocks. When planting of cultures on interfluve plain on lightly overgrown sands of low water capacity the planting of seedlings by combined aggregates type MPP-1 provides the best results. The ecological and economical effectiveness of forest amelioration of pastures forms of the costs of the woody and non-woody forestation resources, their soil-conservation, environment improvement and recreation functions. The effect of one hectare of pasture protective pine coulisses planted on lowdegraded pastures should be about 35 thousand rubles during 50 years (average longevity of forestations), when amelioration of highly overgrazed pastures it would be 130 thousand rubles per year. The main part (80-90 %) of the benefit takes the costs of the prevented loss caused by wind erosion

POLYMORPHISM IN PROMOTER OF PROLACTIN GENE AND ITS ASSOCIATION WITH PRODUCTION TRAITS IN CHICKENS
DescriptionProlactin (PRL) - is a peptide hormone. It effects on metabolic processes in mammals and birds. Indel genotype mutations in a prolactin gene were determined in 595 hens and cocks. Polymerase chain reaction (PCR) were used. We studied four different breeds: Cornish, White Russian, Pushkin, Yurlov crower. Homozygous of insertion II, homozygous deletion of DD and heterozygous ID were observed in all groups. The differences in frequencies of genotypes and alleles were observed in all groups. Homozygotes II and allele I (frequency is 0,83) were the most common for Russian white chickens with high egg production and the lack of the instinct of incubation. Prolactin gene deletion was more common for beef Cornish. The frequency of D allele was 0,84. Pushkin chickens proved to be closer to the egg type. A significant number of heterozygotes with this mutation were noted in a population of Yurlov crower. It is recommended to use gene prolactin as a marker of productive indicators in chickens

VARIETY OF MICROORGANISMS GROUPS LIVING ON BERRIES OF GRAPES
DescriptionThe wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes

BIOLOGICAL AND PRODUCTIVE RESOURCES OF LACTATING COWS AT DENITRIFICATION
DescriptionThe article presents the results obtained in the process of two scientific-practical experiments carried jut on two milk cows (Shvitskay breed) aimed at the antioxidants detoxication properties and mould inhibitor revealing. This factor is actual in the Republic of North Ossetia-Alania as the intensive technologies of the fodder crops cultivation using the nitrate fertilizers are widely applied in the region leading to the excess nitrates and nitrite penetration into the animals’ organism. During the first experiment, the antioxidants of epophen and vitamin C were added into the ration of the lactating cows with the subtoxic dosage of nitrates both separately and in complex. The complex feeding proved to increase the milk productivity, the fat mass and protein mass in milk while reducing the fodder expenditure per product unit. Beside, the lactating cows revealed the digestive and intermediate exchange betterment and the reduction of nitrates and nitrites level in blood. The second experiment helped to study Khadoks antioxidant and mould inhibitor called Mold-Zap efficiency use for the nitrates and aflotoxicin B1 detoxication. The researches showed that the complex admixtures of the said preparations introduction into the rations of the animals increased the milk productivity, fat and protein content and reduced aflatoxineM1 content. The cows activated the digestive and intermediate exchange, accompanied with the nitrates and nitrites level reduction in the organism

DESCRIPTION OF CERTAIN ASPECTS OF THE PRODUCTION POTENTIAL OF SOILS TAMAN PENINSULA
DescriptionThe work presents the results of the scientific research in the Taman Peninsula soil properties. We carry out the historic review of the studies in the Taman Peninsula soils, and its geological structure. We present morphological characteristics of the soil profile for the southern, calcareous, ultra heavy loam chernozem developed from the loessial loams and forming genetic horizons. The studies of the humus content in the soils show the associations between its percentage and the type and intensity of the agricultural use. Studies of the soils structure and composition demonstrate marked aggravation of the soils physical properties caused by grape growing. The best results of the particle size analysis have been achieved for the woodland soils. In woodlands, after their establishment, the soils under the grass and crown layers develop free of the anthropogenic impact. We register self-supporting growth of organic matter and natural processes of soil fertility recovery; therefore, such soils are characterized with a greater content of organic matter as compared to the soils under grape plantings cultivated in the monoculture regime. Reduced soil organic matter (humus) content in vineyards results from the disturbed biological interchange of the matter and increased anthropogenic impact causing erosion processes
