The study of Helianthus annuus L. of domestic breeding in arid Crimea
Authors: Kostenkova E V , Bushnev A S , Vasilko V P 
Published: November 2019

Abstract
An increase in the temperature regime on the planet leads to changes in climatic conditions, as a result of which the aridity of many regions is increasing, which adversely affects, among other things, the productivity of agricultural crops. This issue is also urgent for the Republic of Crimea. The peninsula is characterized by a deficit of precipitation, droughts during the growing season of plants, and an elevated temperature during the period of crop formation. In addition, the situation was aggravated by the cessation of the functioning of the North Crimean Canal, which provided irrigation systems in the region with water. Steep reorientation of the farming system to rainfed conditions implies the introduction of drought-resistant crops into the structure of the cropping land, for which, first of all, it is necessary to identify adaptive varieties and hybrids, as well as to develop a cultivation technology. By order of the President of the Russian Federation No. Pr-1127 as of June 12, 2017, it is necessary to ensure that agricultural producers use, as a priority, competitive domestic seeding and planting material. Since Helianthus annuus L., due to its biological characteristics, is a drought-resistant culture, and the demand for its processed products increases every year, the purpose of our research was to identify the adaptive features of domestic hybrids and the study of plant density in arid conditions of the peninsula. As a result of studies conducted in 2017-2018 in the Research Institute of Agriculture of the Crimea, it was found that the highest yield of seeds of Helianthus annuus L. in agro-climatic conditions of 2017 was demonstrated by hybrids Garant (1.58 t/ha), Signal (1.68 t/ha) and Sprint (1.70 t/ha); in 2018, by Prestige (0.78 t/ha), Signal and Gorstar hybrids (0.59 t/ha). The highest yield of sunflower was observed after sowing with a plant density of 40K ha−1 and amounted to 1.70 t/ha in conditions of 2017 and 0.64 t/ha in 2018.

Abstract
The presence of unique natural and recreational resources in the Baikal region is a basic condition for the development of rural tourism. Rural tourism is becoming an ecological and social alternative to the technogenic development of agricultural areas. The optimal ecological, social and economic effect of the development of rural tourism requires a multifactor consideration of the territories specifics. This is particularly topical in relation to rural settlements located on the lands of specially protected natural territories. In the Baikal region, Tunkinsky administrative district (the only one in Russia) is located within the borders of the national park. Based on the analysis of the ecological, social and economic situation in the Tunkinsky district in the last decade (2009-2019), the authors conducted a preliminary assessment of the potential for the development of rural tourism. The most promising type of rural tourism, providing synergy of the social and economic development of the Tunkinsky district and compliance with environmental requirements, can only be eco-tourism, which is focused on recreational activities. The article proposes the creation of a tourist cluster of equestrian culture for the development of mobile recreation in a civilized manner. In particular, the Buryat ethnocultural equestrian center and the Cossack equestrian culture center in close cooperation and coordination with the administration of the district and the administration of the national park can conduct year-round work on programs and projects for sports, cultural, educational, ethnographic, and health tourism involving all the settlements in the Tunkinsky district.

Abstract
The paper gives a scientific idea of rural areas’ development models. The critical analysis of both theoretical approaches towards the perspective models of rural areas’ development and their various scenarios is given. The territorial disproportions of rural areas’ development conditioned by the long-term dominance of the national rural areas’ development model are identified. Based on the outcome of both domestic and foreign practice, the article gives a survey that shows certain ways of how to modernize and correct the rural areas’ development model. Analyzing the theoretical aspect of rural areas’ steady development, the correlation between a variety of rural economy structure and multifunctional character of rural areas is found out which necessitates the diversification of rural economy by means of different businesses stimulation. It’s proved that rural economy is a complex socioeconomic system and its diversification is conditioned by object-subject interconnection. The authors define the structure of diversified rural economy capable of mobilizing the areas’ available resources and accumulating their major spheres and businesses: agricultural (traditional and lost); non-agricultural (industry and construction, forestry, folk craft and handicrafts; service industry (education, health care system, recreation, service occupation). On the basis of the three-pronged approach - “function-structure-target”-the model of rural areas’ diversified economy which has either some predominant industry or combination of different industries is worked out. The perspective directions of restructuring rural areas’ economy based on expert assessment are also defined in the article.

Published: November 2019

Abstract
Soil degradation caused by human activities currently remains one of the most important environmental problems. Phytoremediation is a group of technologies for environmental clean-up and soil restoration by plants. The level of soil contamination, the bioavailability of pollutants, as well as the accumulation of metals by the plant are crucial for phytoremediation. Currently, it seems relevant to study representatives of the herbaceous flora typical for the region from the point of view of accumulation of pollutant metals. For the study we selected 5 sites located in different areas of Orenburg city. The plots estimated the content of total and active forms of heavy metals in the soil. On the study sites, samples were taken from plants during the growing season. The study analyzed the biomass of 11 plant species from 5 families and 8 elements. As a result of a comparative analysis obtained, the paper presents calculated correlation coefficients (R) between the indicators of the concentration of heavy metals in the soil and plants from the point of view of the accumulation efficiency of Pb and Cd. Plants-phytoremediators accumulate Pb from inactive soil forms – Cichorium intybus L. (R2=0.72 at P<0.05) and Polygonum aviculare L. (R2=0.57 at P<0.05). Plant accumulating Pb due to the absorption of its active forms – Arctium lappa L. (R2=0.4 at P<0.01). Promising phytoremediators of available forms of Cd – Polygonum aviculare L. (R2=0.65 at P<0.05) and Plantago media L. (R2=0.55 at P<0.05).

Abstract

Achillea nobilis L. is a promising medicinal plant in the world. Ecological factors influence the metabolism of plants and their chemical composition. Researches were conducted in 5 districts of the Orenburg region (Perevolotsky, Aleksandrovsky, Pervomaysky, Svetlinsky and Buzuluksky). The spatial and demographic structure of cenopopulations on the ability of accumulation of biologically active substances (BAS) during the procurement of medicinal raw materials A. nobilis was analyzed. As a result of the experiments, it was found that soil fertility (humus content) directly affects the accumulation of pharmacologically active substances in A. nobilis. It has been established that the southeastern part of the Orenburg region is most suitable for growing medicinal raw materials of A. nobilis.

AbstractThe purpose of the study was to compare adaptive changes of the elemental status and hematologic indicators of blood of the Kalmyk cattle brought from the Republic of Kalmykia to the Republic of Sakha (Yakutia). Three groups of animals were formed for this purpose: brought cows (n=75), first-generation calves (n=28) and second-generation calves (n=16) received in Yakutia. The body weight of cows during bio-substrate selection made 480.4±13.8 kg. Age – 2.3-8.0 years. Wool samples weighing at least 0.4 g were taken from the top withers of animals. The proximal part of hair 15 mm long from the root was taken for analysis. The elemental analysis of samples was carried out via ICP-AES and ICP-MS. Blood samples were taken from a tail vein. The study was conducted using automatic hematologic analyzer: URIT-2900 Vet Plus (URIT Medial Electronic Co., Ltd, China). It is found that the wool of cows brought to the Republic of Sakha (Yakutia) had smaller concentration of Ca, Na, K, I, Mn, Zn, B, Sr at higher Hg value in comparison with the first-generation cows and smaller Cu and Zn and higher n Cr, Si, Pb content in comparison with the second-generation animals. The study of blood revealed significant changes in their parameters. Thus, the increase of erythrocytes and lymphocytes is observed from one generation to another with the decrease of the average volume of erythrocytes and hemoglobin in a separate erythrocyte.
Peculiarities of the bone-marrow hemopoiesis, peripheral blood, and the elemental status of the red bone marrow of poultry resulted from copper introduction

Abstract
Metals in an electrically neutral form produced with the method of vacuum condensation from metals are finely dispersed powders. The role of chemical elements in an organism is versatile and multifunctional. However, it is necessary to pay attention to the reaction of an organism on the introduction of chemical elements with different biological roles, which is predetermined by the physiological role of organs and body systems. These include the red bone marrow, which primarily responds to endogenous and exogenous factors by its functional significance. In order to study the influence of copper nanopowders on hematopoiesis of birds, we selected 150 10-day-old broiler chickens which formed 5 groups by the method of analogs (n = 30). All said above allows us to conclude that copper nanoparticles ambiguously affect the bone-marrow hemopoiesis of poultry; increasing the dose and changing the type of introduction activate bone marrow hematopoietic function, in particular, granulocyto-, megakaryocyto-, and erythropoiesis. Different dosages and ways of introduction of copper nanoparticles, in our opinion, ambiguously affect the bone-marrow hemopoiesis of poultry when using copper in doses of 1.7 mg/kg of feed, which is 50% of the daily needs of the organism. E A Sizova et al. proved a stimulating effect of copper nanoparticles in the same dosage on liver cells of chicks.

Published: November 2019

Abstract
An analysis of the literature sources, where the main results of the use of antioxidants in the poultry industry is given in the review article. Adaptation of a bird occurs due to its use of exogenous and endogenous antioxidants under stress. Scientists put forward the natural concept of antioxidant protection of cells. The essence of this protection lies in the fact that antioxidants prevent the leakage of free electrons in the mitochondria of cells by purifying the original radicals. Biologically active compounds, which include antioxidants, are divided into two groups: natural and synthetic. Natural antioxidants in poultry farming are safer, cheaper and can prevent oxidative reactions in food during storage and do not cause metabolic diseases in animals and birds, are a good alternative to synthetic ones.

Abstract
The article compares merino sheep imported from Australian plants in 2004 and 2007 compared and domestic merinos of leading breeding plants of Russia and Stavropol. Australian merinos imported in 2004 did not have a positive effect when crossed with Manich merino ewes. At the same time, the 2007 importation of Australian rams by differentiated selection of Manich merinos depending on their live weight and age, increased meat productivity of their offspring but reduced the level and nature of their wool productivity and comprehensive assessment of animals. In the herds of the Stavropol and Caucasian breeds, the best results were obtained when using stud rams of domestic breeding plants.

Abstract
The problems of adaptation of a highly productive Holstein breed to new natural and climatic conditions and using their productive qualities are relevant. In order to study the influence of paratypical factors on the productive characteristics of Holstein cows, productive qualities of Holstein cows and their paternal half-sisters brought from the USA were compared. It has been established that during their first, second and third lactation periods, Holstein cows had better milk yield parameters than their paternal half-sisters brought from the USA. In Holstein cows, values of repeatability and heritability of milk yield parameters were higher than in their half-sisters. The influence of the “Region of reproduction” factor was observed for the milk yield per lactation. To the least extent, it was observed for the mass fraction of protein. The highest frequency, heritability, and factoriality of milk yield parameters were observed in Pilot’s daughters.

Published: November 2019

Abstract
At this time are underway the search and study of new feed additives with the properties of growth regulators. One of these is the feed additive TTK(G), made from greens wood of Fir siberian (Abies sibirica), soda ash and clay subjected to joint mechanochemical processing. It contains 4-5% triterpene acids and a large number of other biologically active substances, which have a positive effect on the body of animals and birds. The experience of feeding a new additive was carried out in an experimental poultry house by LLC "Kuzbass broiler» in 2018 on broiler chickens of cross ISA Hubbard F-15. Studies have found that the inclusion in the feed of chickens feed additives TTK(G) in the doses 1.0 kg/t and 1.5 kg/t had contributed to the increase in live weight on 6.8-6.3% (p<0.001), the average daily growth of 6.8-5.6% and a decrease in feed costs per 1 kg of growth by 6.0-5.2%. At the same time, hematological parameters (hemoglobin content, the number of red blood cells and leukocytes in the blood) were normal, which suggests that the feed additive from the needles of fir does not have a harmful effect on the body of broiler chickens.
