06.00.00 Agricultural sciences
DescriptionLodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

GRAPE VARIETIES OF THE ANAPA AMPELOGRAPHIC COLLECTION AND THEIR USE IN BREEDING WORK
06.00.00 Agricultural sciences
DescriptionIn the world, huge work is being done to create global information banks of plant genetic resources. The need for conservation and rational use of genetic resources in modern conditions has become very relevant. Genetic collections are the basis for selection work: creating new varieties, replenishing the assortment with new, classic, introduced and native varieties, adapted to the natural (soil and climatic) conditions of the cultivation sites. In the Anapa ampelographic collection, 4911 varieties of various ecogeographical and genetic origin are represented, the use of which provides great opportunities for creating and breeding new varieties, their state testing and zoning. In the gene pool of the ampelographic collection, most varieties of V. vinifera L. grapes are represented by local honeycombs of different regions of the grape culture, and more than one fourth of varieties of V. vinifera L. are obtained from intraspecific crossings. Despite the value of local varieties of grapes, they do not always meet all the requirements of production. Therefore, to improve the local assortment, it is necessary to carry out selection - breeding new varieties of grapes. This article presents the long-term results of the work on the selection of varieties of table and technical directions in the Anapa ampelographic collection used for breeding. Also, the role of the genetic collection in the creation of new generation varieties by combinative selection is shown - as donors for creating new varieties of grapes. Dedicated varieties are the sources of valuable traits, which are given primary importance and are especially important for the viticulture of the Russian Federation

06.00.00 Agricultural sciences
DescriptionUnder the current conditions, it is very important to boost the production of pork and improve its sanitary and hygienic quality for the successful handling of problems subjected to import substitution of meat products. This can be reached by means of strengthening of food reserve. For that purposes, in the frame of two experiments yacon tubers in combination with enzymatic agent protosubtilin GZx have been introduced in the intakes of fattening pork stores instead of fodder beat, and various doses of carbitox adsorbent have been additionally added when superfluous background of heavy metals was observed. During the 1st experiment, the substitution of fodder beet with the similar quantity of yacon tubers has allowed the animals of experimental group to outweigh the ones from the control group on 7,5% in the terms of gross formation of body weight, and to gain 100 kg of body weight for 7 days ahead of the animals from control group as well. Additionally, fodder costs per product have been reduced and the morphological and biochemical values of animals blood have been optimized. Based on the data from 2 nd experiment, it has been defined that the better dose for feeding of adsorbent carbitox was 2,0 kg per tonne of concentrates thereby the animals of 3rd experimental group had reasonably higher body weight gain and thereby higher feed-conversion ratio by products. Therewith, the animals intermediary metabolism has been speeded up due to optimization of morphological and biochemical values of blood and reduction of heavy metals content in blood serum, in other words level of zinc, lead and cadmium was not exceeding maximum allowable concentration

INCREASING OF BIOLOGICAL POTENTIAL IN POULTRY DUE TO THE USE OF PROBIOTICS
06.00.00 Agricultural sciences
DescriptionTo improve the quality, safety and competitiveness of the domestic raw materials of animal origin the use of probiotics in the poultry industry is a priority and promising direction of the development of organic agriculture. One of the key problems of the production of probiotics is to provide actively stable preparations. Biocompatibility of the indigenous microflora with probiotics, medical form and individual range of antibacterial activity of probiotics have a significant impact on the introduction of probiotics in new habitat conditions and its effectiveness. Consideration of these factors can enhance the effectiveness of probiotics. Currently, the available literature has insufficient justification of certain doses of administration and methods of using different probiotic preparations. The materials present and summarize the results of the research concerning the use of probiotics in the poultry industry, based on the achievements of Russian and foreign scientists. In addition, based on the analysis of various sources of scientific literature, we suggest ways to solve the problem of probiotic therapy and give some recommendations on the organization of the technological process of selection and application of different probiotics in poultryfeeding. Raw meat from poultry reared with the use of probiotic preparations is safe, because metabolites of probiotic microorganisms are not accumulate in the body tissues. Researches of biosynthesis regularities of probiotics were made at the cellular level, including genetic aspects, features of regulation of secretion, dependence on the cultivation conditions, interaction with binding sites on the cell surface, participation in the vital activity of the population of individual cells. The use of probiotics contributes to normalization of the intestinal microflora, activation of protein metabolism, productivity increase, reduction of feed costs per unit of production and increasing of poultry industry economic efficiency as a whole

DescriptionThe study was carried out during 2010-2015 years in the All-Russian research Institute of Grain Crops named after I.G. Kalinenko (the laboratory of the cultivation technology of plowing crops), situated in the southern soil-climatic zone of the Rostov region, which is characterized with the unstable and insufficient humidity. The trials were conducted on the heavy loamy, calcareous chernozem obyknovenny (natural blacksoil). The object of the study was the grain sorghum variety ‘Zernogradskoe 53’, approved to use in the Rostov region. The agroclimatic conditions during the years significantly differed during the vegetation in the amount of precipitations (from 110.2 mm in 2010 to 200.2 mm in 2013) and in the temperature regime (from 2512.9 0С in 2010 to 2788.8 ºС in 2015), that allowed evaluating the grain sorghum productivity more objectively. The article gives the study results of the effect of the weather conditions on the duration of vegetation, productivity and grain quality (content of protein, oil, ash and fiber). The article showed the estimated interconnection among the sum of active temperatures, precipitations and hydrothermal coefficient during the sorghum vegetation with the principal economic-valuable traits of grain sorghum. The sum of active temperatures showed the greatest effect on the duration of the vegetation (r=0.89); the sum of precipitations during the vegetation had the greatest effect on the productivity (r=0.80). There was determined the strongest positive correlation of the sum of active temperatures with the content of protein in the grain sorghum kernels (r=0.80) and the average negative correlation with the content of oil (r=-0.69). The sums of active temperatures and precipitations, when the grain sorghum gives the largest productivity, were established

DescriptionThe article deals with the issue of improving the profitability of sheep breeding by using improved mutant genotypes in the breeding system. The results of studies of the main indicators of economic-useful traits are given, the dynamics of growth, level and quality of wool productivity of sheep of improved genotypes obtained on the basis of such breeds as Soviet merino and Stavropolskaya, as well as firstgeneration daughters cultivated in themselves are estimated. It was found that at birth, the live weight in the groups of the 3 group (the breeding of half-blooded hybrids "in oneself") was higher than that of the females from the 1 and 2 groups, respectively, by 0.50 kg, or 13.1%, and by 0.20 kg or 5.2% (P> 0.95). At a more senior age, the young, having a large live mass at birth, retained its rank position. The highest indicator of the cutting of physical wool was observed in animals of the 2 group, obtained as a result of the use of sheepproducers of Stavropolskaya breed on sheep of the Soviet merino. The parameters of the 1 and 3 group were lower by 0.6 kg - 12.3% and 0.17 kg - 3.5% (P> 0.95), respectively. The conclusion is made that the use of sheep-producers of the Stavropolskaya breed on the uterus of the Soviet merinos breed had a positive effect on the wool productivity and the live weight of the hybrid offspring. Further breeding of half-blooded hybrids “in oneself” showed the possibility of reproducing improved genotypes without losing the acquired qualities
