abstract 1301706016 issue 130 pp. 243 – 252 30.06.2017 ru 41
The article presents the materials of research on studying of influence of various levels of crude fat in the complete feed (CF) for the young geese of Lindovskaya breed on chemical composition and organoleptic quality of goose meat. In the experimental groups we increased the concentration of crude fat in the start and finish of the CF to 7.4 % and 6,85 %, respectively. As the lipid supplement, we used sunflower oil. It is established that muscle tissue of geese, consuming finishing CF with sunflower oil, has a more pronounced taste, odour, tenderness and juiciness. We may highlight the tendency to increase the proportion of monounsaturated oleic acid, in the background of the decrease of specific weight of palmitic acid in the fat muscle 60 day goslings who received the start and finish of CFs with the addition of sunflower oil

ANALYZING THE COMPLEX OF HARMFUL ORGANISMS IN AGROCOENOSIS OF SOUTHERN FRUIT CROPS IN HUMID RUSSIAN SUBTROPICS

abstract 1301706024 issue 130 pp. 321 – 334 30.06.2017 ru 36
For the research period (2003-2016), 57 pest species and 46 pathogens were recorded on stone and pomaceous fruits in humid Russian subtropics, among which the representatives of the order Lepidoptera and the division Ascomycota predominate. The greatest number of the species was recorded on the apple tree - 35 pests and 25 pathogens, the smallest - on cherry and sweet cherry trees (13 and 10, respectively). 43,7 per cent of the species are polyphages, while the relative abundance of monophages among fungi is higher than among arthropods. The species with activity in the summer are prevalent. A group of species that are harmful in humid subtropical environments all year round (11 species of phytophages and 19 pathogens) was identified. Analyzing the changes in the species composition of the complex through the time, we can speak about the relative stability of the dominant species. The group of the typical dominant species of pests for almost a century has included Grapholita molesta Busck., G. funebrana Tr., Cydia pomonella L., Taphrina deformans (Berk.) Tul., Stigmina carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh. et Ruhland) Honey, M. fructigena Honey, Podosphaera leucotricha (Ellis & Everh.) E.S. Salmon, Venturia carpophila E.E. Fisher and pear V. pyrina Aderh. Eriosoma lanigerum Hausm., Scolytus mali Bechst. and Tranzschelia prunispinosae (Pers.) Dietel are currently dropped out from the group of the dominants; Halyomorpha halys Stål, which is a new pest for Russia, was added. Groups of the species with sharp fluctuations in abundance or frequently encountered were distinguished

THE CONTENTS AND FORMS OF LEAD COMPOUNDS IN LEACHED CHERNOZEM OF THE WESTERN CISCAUCASIA IN TERMS OF AGRICULTURAL SOIL GENESIS

abstract 1301706059 issue 130 pp. 833 – 845 30.06.2017 ru 38
The contents of lead in soils are primarily determined by regional factors: the composition of parent rocks, relief, climate, vegetation. In recent years, these factors have increased the anthropogenic source of element. In order to assess its impact, requires knowledge of the natural, i.e., background lead levels, the so-called reference points, which can later be used to monitor changes occurring in the soil. Under background refers to the content of the element in soils at a great distance from the areas of receipt of contamination. Background content of lead in each type of soil depends mainly on composition of parent rocks. The correlation coefficient between the content of lead in parent rocks and soils, with the background contents is equal to 0,86±0,17 at p=0,95. For each soil type there are low variations in lead content due to the composition of parent rocks. Lead concentrations in the soils increased at the expense of its receipt from the atmosphere, irrigation water, drainage during mining, as a result of agricultural use, lead containing chemicals. Comparing the obtained results with existing currently permissible concentrations (APC, MPC) it is necessary to note that the lead content in leached chernozem soil after three rotations of the rotation may not cause any pathological changes or anomalies in the course of biological processes and lead to accumulation in the agricultural plants, and therefore may interfere with biological optimum

BIOENERGETICS ESTIMATION OF LONGTIME FERTILIZERS’ APPLICATION IN THE CROP ROTATION

abstract 1301706061 issue 130 pp. 856 – 872 30.06.2017 ru 23
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of winter wheat varieties was investigated and bioenergetics estimation was given. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten field crop rotation: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content (0-30sm), depending on the power of nutrition backgrounds in the arable soil layer. It was found that the selection of predecessors and the differentiated application of mineral fertilizers ensure stable high yields of grain and they exceed the varieties without fertilizers by 40-79%. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. A strong correlation between yield and agronomic methods was determined. The most effective predecessor for the wheat cultivation by the turnover of furrow slice is sainfoin, peas and wheat. More labor intensive and energy-consuming predecessors are grain maize and sugar beet

abstract 1301706070 issue 130 pp. 958 – 974 30.06.2017 ru 12
The trials were conducted in 2013-2015. Research objects: apple trees cv. Zhigulevskoye/62-396, year of planting – 2007, at 4,5x1m. Place of research – experimental orchard of ”I.V. Michurin Federal scientific centre " in Tambov region. The goal of research: to study the effect of fertigation and foliar nutrition in an intensive apple orchard. During the research there were done yield records, was determined the content of nutrients in leaves and soil. In the soil there was also determined humus content and acidity, fruits were analyzed on vitamin C, saccharides and organic acids contents. Nitrogen in leaves and soil was determined by Kjeldahl method, phosphorus by photocalorimeter KFK-3, potassium and calcium by flame photometer Jenway PFP-7. We have established the optimal average application rate for fertigation in conditions of the Central Chernozem zone of Russia, which could be used to calculate specific application rates with data of soil-leaf diagnostics. In our research, it is shown that the use of this application rate had no significant negative impact on the studied parameters of soil. It is shown that the biochemical composition of fruits is largely determined by weather conditions of the year of vegetation and foliar nutrition. Maximum efficiency of measures for mineral supply optimizing is achieved only with the good combination of fertigation and foliar nutrition

THE PATH FOR IMPORT- SUBSTITUTION OF THE USE OF FOREIGN BREED PIGS

abstract 1301706078 issue 130 pp. 1058 – 1065 30.06.2017 ru 11
The extensive path for development in the country in the twentieth century caused low competitiveness of Russian pig production. The productivity of domestic pig production was significantly lower than in Europe, US, Canada and China. Feed costs per 1 kg of gain were 2-3 times higher with a low yield of piglets from a sow per year: 14-16 with an average European 25-27 heads. The country did not have enough meat; as a result, a significant amount of meat products was imported to Russia. Restrictions on imports in connection to the imposition of embargoes contributed to the increase in demand for domestic products and opened new opportunities for Russian producers. One way to increase the production of pork is to use pigs with a high genetic potential for productivity, imported for breeding from Canada and Europe. Based on the conducted studies, it has been established that pigs of foreign breeding have high reproductive qualities, which proves the expediency of their application in commercial pig production to increase the efficiency of the industry development and reduce the import of pedigree youngsters from abroad. The implementation of two breed gilts will help increase productivity in the industrial pig production

abstract 1291705020 issue 129 pp. 236 – 247 31.05.2017 ru 11
The presented research is devoted to the development of the import-substituting production technology of the proteins dresser for food from local vegetable resources, in particular, of lupine. Lupine seeds contain about 40% of protein rich in all irreplaceable amino acids. Protein of lupine noticeably differs from protein of soy in inhibitors content, and namely, proteases, that does not cause allergic reactions. The main part of oil composition of oil of lupine is maid up of linolenic, linoleic and olein acids. Use of lupine seeds in production of complex raw structure products will allow to increase the biological value of a proteins component of a traditional type of raw materials of phytogenesis and to reduce the available deficit of protein. It is a will-know fact, that lupine is added to the recipes of buns, fermented milk and cottage cheese products, rich crackers and long cookies. Technologists have recently received a certain concentrate from lupine seeds of high biological value, and a pastelike concentrate of lupine which can be used as a filler in milk, meat, baking and confectionery industries is being under development. The results of the research show that seeds of lupine can be considered as one of the perspective sources of white and competitive ingredient for developing new recipes and technologies of different types of multicomponent food. It is necessary to continue the research on creation of different types of food with use of lupine seeds. Thus, the products received from lupine seeds can be used as raw materials for improvement of quality of food and as additives for creation of compoundings of new types of foodstuff
