The purpose of the research, the results of which are revealed in the article, was to develop methodological approaches for calculating the genetic potential of productivity in pig breeding. The research was carried out in a breeding facility for animal breeding FG "Shubske", Bogodukhiv district, Kharkiv region. At the first stage, the productivity of the offspring (fattening qualities) of the UNI family saws of Welsh breed in the breeding facility for FG "Shubske", Bohodukhiv district, Kharkiv region was evaluated for two consecutive generations. The results show that in general for all evaluated uteri, there was a reduction in the fattening period by 0.60 days with a reduction in feed consumption by 0.04 feed units. At the same time, the thickness of the fat on the estimated family at the level of two estimated generations there was a regression of 0.10 mm. According to the obtained data, methodological approaches that are effective in direct indicators (reproducible qualities, slaughter qualities, etc.) turned out to be uninformative in inverse indicators, where it is desirable to reduce values (age of live weight, feed consumption, fat thickness, etc.). It is proposed to use the given formulas only for direct indicators, and for inverse indicators to use formulas for a slightly modified mathematical apparatus. Considering these features, a modified methodological approach to the calculation of this indicator by inverse indicators is proposed. Using this methodological approach, the calculation of the genetic potential of productivity by fattening qualities was carried out and the degree of realization of the genetic potential of animal productivity was determined. According to the results of the assessment of the genetic potential of productivity (according to the proposed methodological approach) of the fattening qualities of the offspring, the sow B19056 was was marked by the highest values of the genetic potential of productivity. Also, without considering the values of lifelong fat thickness in the offspring, for further breeding work, based on the assessment of the genetic potential of productivity, sows B19004 and G19308 can be used.

Structure And Functions

The accumulation of knowledge about the structure and functions of the epidermis will make it possible to solve the most important practical tasks of forming the animals’ productivity and health. Two breeding groups have been researched: 1) purebred young boars, 2) young boars with the blood of Finnish Landrace. The studies were carried out when the animals reached live weight of 100 kg, and the control slaughter was made. The results of the Poltava Meaty Breed pigs’ skin epidermal barrier research made it possible to trace significant differences in the ratio of the main epidermis layers in animals of different genotypes. The genotype influence was 15.45 %. An-imals with the blood of the Finnish Landrace have lower biological possibilities for life in the given climatic and technological conditions, that is, they are less promising for further breeding work.

Проведён анализ результатов селекционно-племенной работы в Ярославской области по данным за 2018–2019 гг. Так, на 1 января 2020 года в сельхозпредприятиях Ярославской области содержалось 95,4 тыс. голов крупного рогатого скота, в том числе 42,8 тыс. коров. В 2019 году было всего пробонитировано 36,6% скота, в том числе коров 52,5%. По результатам комплексной оценки большинство (95,3%) пробонитированных животных отнесены к классам элита-рекорд и элита, из них 95,5% коров. Валовое производство молока в регионе за анализируемый период выросло на 3,4 тыс. тонн и достигло 292,3 тыс. тонн. Надой молока на фуражную корову составил 6967 кг, в племенных хозяйствах – 8077 кг. Выход телят на 100 коров в племенных стадах остался на уровне 2018 года – 85%. Продолжительность сервис-периода составила 126 дней. Осеменение тёлок в среднем происходит в возрасте 16,4 месяцев (живая масса 431 кг). За исследуемый период продолжительность эксплуатации коров в племенных стадах составила 3,1 отёла, основными причинами выбытия коров остаются гинекологические заболевания и заболевания конечностей. Для полной реализации генетического потенциала стад Ярославской области необходимо повысить интенсивность выращивания ремонтного молодняка, проводить своевременное выявление половой охоты всеми доступными для предприятия методами (визуальный метод с использованием датчиков активности животных, окрашивание корня хвоста и т.д.) в сочетании с комфортным содержанием стада и полноценным сбалансированным кормлением. The analysis of the results of selection and breeding work in the Yaroslavl region according to the data for 2018–2019 was carried out. So, as of January 1, 2020, the agricultural enterprises of the Yaroslavl region contained 95.4 thousand heads of cattle, including 42.8 thousand cows. In 2019, a total of 36.6% of livestock were judged including 52.5% of cows. According to the results of a comprehensive assessment the majority (95.3%) of the judged animals were classified as elite-record and elite of which 95.5% were cows. Gross milk production in the region for the analysable period increased by 3.4 thousand tons and reached 292.3 thousand tons. Milk yield per forage cow was 6967 kg on bred livestock farms – 8077 kg. The yield of calves per 100 cows in breed herds remained at the level of 2018 – 85%. The duration of the service period was 126 days. Insemination of heifers occurs on average at the age of 16.4 months (live weight 431 kg). During the researched period the duration of the operation of cows in breed herds was 3.1 calving, the main reasons for the cow disposal remain gynecological diseases and diseases of the limbs. For the full realization of the genetic potential of the herds of the Yaroslavl region, it is necessary to increase the intensity of breeding replacement young animals of the cattle, to carry out timely detection of estruation by all methods available for the enterprise (visual method using animal activity sensors, coloring of the tail root, etc.) in combination with comfortable keeping of the herd and complete balanced feeding.

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

The present study was conducted to assess the effect of supplementation of Multi-enzymes with lysophospholipids on production performance of pure line White Leghorn layers. Body weights before and after the experiment did not differ significantly across the experimental diets. Irrespective of the dietary treatments, the birds gained 3.83 per cent of live weight relative to its initial body weight. Mean per cent Hen housed egg production was significantly (Pis less than 0.05) higher in diet supplemented with 0.10 MEC-L than other groups. Mean egg weight and average daily feed consumption during 25 to 35 weeks of age indicated no significant effect of enzyme supplementation. Average daily feed consumption per bird in control, 0.05 % and 0.1% multi-enzyme supplemented groups was 108.13, 105.66 and 107.67 g respectively and birds offered control diet recorded numerically more feed intake than enzyme supplemented groups. Comparatively low feed per egg was observed in 0.10 per cent group followed by 0.05 per cent group which offers economic benefits than control diets. However, the egg quality traits between different dietary enzyme supplementation groups showed no significant difference.

The objective of this study was to evaluate the associative effect of monensin sodium to virginiamycin and/or essential oils on performance, consumption of nutrients and dry matter, apparent digestibility, feeding behavior and carcass characteristics of feedlot finished steers. The experiment lasted 106 days with 10 days of adaptation and 96-day trial, and had 32 crosses angus steers, average age 12 months and average weight of 376 kg, divided into 16 stalls, the weighing took place every 21 days and at the end of the experiment. The treatments consisted of the combination of the following additives to the diet included: Monensin sodium, 200 mg day-1 (MO); Monensin sodium, a dose of 200 mg day-1 + essential oil dose of 1.5g day-1 (MO+EO); Monensin sodium, a dose of 200 mg day-1 + virginiamycin, 200 mg day-1 (MO+VI); Monensin sodium, 200 mg day-1 + essential oil dose of 1.5g day-1 + virginiamycin day, 200 mg day-1 (MO+EO+VI), each treatment had four repetitions, where each repetitions consisted of a bay with two animals. The MO+VI association in relation to MO only increase in average daily gain (ADG) of 24.44%, 22.35%, 21.10% and 17.31% in weighing 42, 63, 84 and 96 days, similar the combination of MO+EO+VI which provided an improvement of 21.94%, 13.59%, 15.45% and 14.75% respectively in the same weightings. The daily carcass gain and carcass overall gain were higher in associations MO+VI and MO+EO+VI and provided an average gain of 16.67 kg more compared to MO and MO+EO. In the parameters feed efficiency, dry matter intake and nutrient expressed in kg day-1 and percentage of live weight were not observed differences (P > 0.05) between treatments. Data on apparent digestibility, feeding behavior and carcass characteristics did not show statistical difference between treatment, except for fat thickness which was higher when associated with any of the additives to the MO, and farm weight was higher in associations containing VI. Associating MO+VI or MO+EO+VI proved to be best in this work compared to MO+EO or only MO in the diets of steers in termination.

The main goal of our article is to encourage personal reflection within the field of sport management as a tool to strengthen methodological approaches in our research. We explore and discuss the utility of collaborative self-ethnography as one way to acknowledge personal identities through a reflexive account of our experiences as sport fans and sport researchers with this methodology. We draw on a previous study of our experiences as sport fans to illustrate techniques, downfalls, and benefits of studying one’s experiences in a collaborative methodological approach. We have two objectives: First, we hope to encourage sport management researchers to acknowledge and reflect on their personal identities related to sport, such as being a fan, coach, volunteer, or former participant, in their research. Second, we aim to demonstrate the utility of collaborative self-ethnography as one way to incorporate reflexivity in sport management research and theory development.

Subject. As digital technologies spread across all industries, active processes of digital transformation need to be managed both nationally and regionally. Assessing the extent of digitalization across types of economic activities is the key issue for setting up the socio-economic development strategy of the region and evaluating its efficiency. Objectives. The study is aimed to formulate and test methodological approaches to assessing the digitalization in types of economic activities and the potential of digital technologies for the real economy. Methods. The study relies upon the dialectical method, systems approach, questionnaires, expert approach, interpretation of empirical facts through tables, etc. Results. We devised a methodological approaches to assessing the extent of digitalization in types of economic activities across regions. The approach combines the quantification and evaluation of the process and helps determine the extent of local digital transformation at the regional level. We devised and tested the methodological approach to rating digital technologies, which have the high potential for raising the competitiveness and resilience to competition of the industrial sector in the Russian regions. As opposed to the existing approaches, the approach accounts for the current scale of digital technologies in the national economy, the potential for growth in the demand and supply in the domestic and foreign markets, and the potential for import substitution with respect to foreign technologies and products. Conclusions and Relevance. What makes the proposed methodological approaches more preferable is that they help assess not only the extent of digitalization in types of economic activities and the predominance of certain types in industrial enterprises, but also determine their potential for import substitution in terms of digital security.

Статья посвящена рассмотрению основных подходов к изучению музыки в шаманизме, сложившихся и функционирующих в современной антропологии и музыковедении. Автор характеризует различные направления в каждом из них, приводя в качестве примеров и анализируя наиболее показательные труды. Литература (источники и исследования) подобрана таким образом, чтобы позволить читателю самостоятельно расширить библиографический список. Изложение следует хронологическому порядку и отражает логику развития научного знания в избранной области. Два наиболее ранних подхода - музыкально-этнографический и музыкально-теоретический - продолжают сохраняться и развиваться до сих пор. Относительно недавно на их основе начал формироваться комплексно-текстологический подход. Все они ориентированы на изучение самой музыки в этнографическом контексте (тексториентированные подходы). Позже появляются многочисленные труды музыкально-антропологического и культурологического направлений, довольно подробно исследующие концептуальные и функциональные аспекты шаманской и, шире, сакральной музыки в разных традициях (контексториентированные подходы). В последнее время появляется все больше работ, в которых в разной форме реализуется музыкально-психологический подход, причем спектр направлений внутри него весьма широк - от культурологических до нейрофизиологических. Большинство подобных исследований проводится за рубежом. В результате предпринятого обзора автором определены наиболее актуальные направления изучения проблематики «музыка и шаманизм». Это комплексный анализ полных вербально-музыкальных текстов шаманских камланий, исследование характера взаимосвязи звукового компонента с измененными состояниями сознания, изучение региональных традиций, а также, в перспективе, развитие методологии сравнительно-исторического исследования музыкальной составляющей шаманских традиций. This article examines the main approaches to the study of music in shamanism that have been developed and those that are current in modern anthropology and musicology. The author characterises the different areas of research covered in each approach, giving examples and analyzing representative works. The presentation of the different approaches is chronological and reflects the logic of the development of scholarly knowledge in the given field. The two earliest approaches - musical-ethnographic and musical-theoretical - continue to be used. Relatively recently, an integrative and textological approach has begun to be applied on their basis. These textually-oriented methods aim at studying the music in an ethnographic context. Subsequently context-oriented approaches have appeared, applying musical-anthropological and culturological methods that explore the conceptual and functional aspects of shamanic - and, more broadly, sacral - music in different traditions. Recently there have been an increasing number of studies that implement a music-psychological approach in various forms. The range of directions within this approach is broad, from culturological to neurophysiological; most such studies are conducted outside Russia. The author also identifies the most relevant current areas of research. These include: the comprehensive study of the verbal and musical texts of shamanic rituals; study of the nature of these texts’ relationship to altered states of consciousness; and comparative research on the most significant regional traditions. She looks forward to the development of a methodology appropriate for comparative historical research on the musical component of shamanic traditions.
