ВПЛИВ ЗАНЯТЬ АЕРОБІКОЮ НА ФУНКЦІОНАЛЬНІ МОЖЛИВОСТІ СТУДЕНТОК НЕФІЗКУЛЬТУРНОГО ФАХУ

The material of this scientific publication is, in fact, a confirmation of the verification of the effectiveness of the training system model using various types of recreational aerobics for non-physical education students. The obtained statistical data of the pedagogical experiment confirmed the hypothetical nature of the research tasks outlined by us. Analysis of the latest research and publications confirmed the relevance of our scientific search, the logical algorithm of which was based on the results of solving a few problematic scientific questions, which were separate scientific tasks. Hypothetically, the results we expected had not only theoretical solutions, but were solved because of practical application in the educational and training process of the aerobics section. Information from relevant scientific sources and legal documents allowed proving the relevance of the declared topic, building a logical basis of scientific research, determining the purpose, objecting, and subjecting of a scientific article and predicting the results of a scientific experiment. In the literature we studied, we did not find any adequate methods or innovative physical culture and health systems for correcting the functional capabilities of non-physical education students by means of health aerobics. The results of the pedagogical experiment, analyzed in this publication, confirmed prognostic ideas and views regarding the use of the directions of physical culture and health aerobics for the correction of functional capabilities of non-physical education students. After the implementation of the tasks of the scientific research, we obtained a statistically probable improvement in the functioning of the respiratory and cardiovascular systems and the general level of work capacity of the girls of the Sumy Polytechnic. We also noted positive changes in the control group of female students at the Sumy National Agrarian University, but the errors were of a random nature, which indicates that the training effect of aerobics for a long period of time gives a positive effect. We recommend using the data of our scientific research to conduct training classes on aerobics in the conditions of a higher professional institution of education that does not have a physical education profile. Keywords: aerobics, health of female students, recreational types of aerobics, recreation, training system, fitness technologies, functional capabilities.

Agricultural education in times of war: Strategic visions, leadership practices and post-war reconstruction

In the post-war reconstruction of Ukraine, agricultural universities will provide the state with specialists capable of implementing the seamless integration of “green” benchmarks. The full-scale war has not only threatened the sustainable operation of all spheres of higher education institutions but also forced them to look for new ways of adaptation and development. This study aims to assess the readiness of higher education institutions in the agrarian sector to meet the personnel needs of the state in the medium-term of post-war reconstruction. The paper used a group of parameters with specific indicators: education (change in the number of graduates at the Bachelor’s and Master’s educational levels, the ratio of publicly-funded and fee-based education seekers, changes in the average entrance score), science (change in the number of articles published in Scopus and the corresponding h-index, the number of Erasmus grants received, the amount of budget funding for science), recognition (academic ranking of higher education institutions by the Webometrics and Top-200 Ratings), and financing (estimated amounts of funding from the general and special fund, and their ratio). The study offers a unique approach to calculating the Integrated Sustainability Index of higher education institutions. This index clearly illustrates how efficiently 15 agricultural higher education institutions have adapted to wartime transformations. For example, Sumy National Agrarian University and Lviv National Natural Resource Management University have this index exceeding 30%. The study draws attention to the problematic areas of university activity during the war and suggests extending the valuable experience of Sumy National Agrarian University.

The article examines the peculiarities of the implementation of an integrated system of marketing communications as an element of international marketing in the institution's activities. The author defined the main principles of the integrated system of marketing communications and developed a scheme of the main stages of implementation of this system in the international marketing activity of the institution. An integrated system of marketing communications in the structure of international marketing makes it possible to increase the effectiveness of marketing communications and ensure their integration, which is especially important in the conditions of growing competition and saturation of the global market. The Sumy National Agrarian University was chosen as the object of the study, which trains Ukrainian and foreign students, which proves the fact that the educational institution operates on the international market and uses international marketing tools. On the example of SNAU, the possibility of using an integrated system of marketing communications during the work of attracting education seekers from different countries of the world was investigated. The author determined that an integrated system of marketing communications for an educational institution will consist of advertising, career guidance activities, exhibition activities, public relations (PR), personal communications and the Internet. It has been established that in order to properly build an integrated system of marketing communications of an educational institution, it is necessary to implement the following steps in the international marketing system – the selection of the target audience using the 5W methodology, the selection of the main goal for the implementation of communications in terms of the strategic goals of the institution and the analysis of the communication channels of the educational institution and the selection of the best of them. The author identified the main advantages of implementing an integrated system of marketing communications in the international marketing strategy of an educational institution.

Policy evolution of personnel management in Chinese educational institutions: A comprehensive policy circle analysis

The reform of education personnel management policies has been carried out progressively to ensure the achievement of educational goals. A systematic analysis of the personnel management policy circle, including policy design, content, and implementation, is crucial to improving the accuracy and effectiveness of such policies. Through a comprehensive review of policy evolution, this study aims to systematize the design and content of policies on personnel management in educational institutions in China. It was determined that personnel management is increasingly concerned with the efficiency and effectiveness of goal achievement, policy design, system reform, and mixed-used management methods. A questionnaire survey was conducted among 420 respondents in 25 preschool institutions in five cities of Henan province in China. A total of 362 questionnaires were deemed valid out of 397 retrieved, including 24 from principals and 338 from teachers. The statistical analysis results identified the problems in policy implementation, including the laxly enforced teacher qualification system, inadequate teacher professional development, poorly implemented training policies, unattractive salaries and benefits, and the undesirable assessment system. For example, 5.89% of the respondents still need teaching qualification certificates. Only 1.1% of the respondents had senior titles. 2.76% of the respondents are still paid less than the minimum standard. In response to the situation, this study suggests effective countermeasures for educational administrative authorities and institutions. The findings could provide a reference for further optimization and development of personnel management policies. AcknowledgmentsThis study is supported by Sumy National Agrarian University in Ukraine and the Talent Special Support Program for Doctoral Studies of Henan Institute of Science and Technology in China.

Improving of EFL teachers’ methodological preparation for the introduction of mobile learning requires further researches in this sphere.

RESEARCH OF THE QUALITATIVE COMPOSITION OF MILK OF COWS OF SIMMENTAL BREED

Modern dairy breeds of cattle have high milk yields. This is especially true of breeds created using Holstein breed [14]. At the same time, scientists have repeatedly stated that the use of Holstein breeders deteriorates the quality characteristics of milk productivity. Therefore, the influence of conditional blood by Holstein breed significantly affects productivity. However, researchers emphasize that the breed as a genetic factor has a significant impact on milk productivity. This explains the influence of the biochemical composition of milk on the profitability of the dairy industry.
 Dairy breeds that have been created in Ukraine over the past twenty years are characterized by a sufficient level of milk yield and quality indicators. The level of milk yield of animals is more than 7.0 thousand kg of milk with fat and protein content in milk above 3.8% and 3.2%, respectively. Some breeds, which are created on the basis of domestic combined breeds are characterized by a sufficient level of milk components. Their fat content in milk is more than 4.0%, and protein – more than 3.4%. During lactation, the content of milk components changes.
 The aim of our work was to investigate some indicators of the biochemical composition of milk of Simmental cows.
 Materials and methods. The research was conducted on Simmental cows kept in the Mykhailivka PZ of the Lebedyn District of the Sumy Region (n = 46) and the Urozhay SFG of the Romensky District of the Sumy Region (n = 30).
 For sampling of milk used counter – indicator IU-1. The milk sample was stored in a plastic container (25 ml) during the day at a temperature of +3C0, using the preservative chrompic. The content of fat and protein in milk was determined in the laboratory of Sumy National Agrarian University on the equipment Ultrasonic milk analyzer Master Classic manufacturer Milkotester Ltd (Bulgaria).
 The results of the research were processed by the methods of mathematical statistics using the "Statistica-6.1" package in the Windows environment on a PC.
 The animals fully meet the requirements of the breed standard for both the first (standard 2700 kg) and the third lactation (3500 kg).
 In terms of milk yield, Simmental cows met the requirements of the breed standard for both the first and second lactations.
 Biochemical analysis of milk was carried out to determine the level of such indicators as fat, protein, lactose, dry matter and dry nonfat milk residue. According to all the studied features, the first-born were inferior to adult animals. A statistically significant difference was found between the fat and protein content of milk in favor of adult animals. As a result, it can be argued that there is a significant difference in the amount of dry matter and dry skim milk residue between animals of different ages. Adult animals met the breed standard in terms of both fat and protein content, the first-born animals were slightly lower than the standard in terms of protein content.
 There are relationships of different directions and magnitudes between the contents of individual components. Statistically significant correlation coefficients were found between the content of: fat and protein; fat and dry matter; protein and dry matter; protein and skimmed milk powder.
 Conclusions. As a result of research, it was found that both first-born and adult Simmental cows are characterized by a sufficient level of milk productivity with high quality milk. In all respects, they met the requirements regulated by the breed standard, with the exception of the first in terms of protein content. There is a significant positive correlation between individual indicators (0.75 ± 0.03–0.96 ± 0.01).

Formation of economically useful traits in cows of ukrainian black-and-white dairy breed of different genotypes by kappa-casein

The influence of kappa casein genotype on the formation of economically useful traits of Ukrainian black-and-white dairy cattle has been studied. Genotyping of 25 heads of cattle of the Ukrainian black-and white dairy breed belonging to the Breeding Plant of the State Enterprise "Research Farm of the Institute of Agriculture of Northern East of NAAS" was carried out. Determination of polymorphism of the kappa-casein gene was performed in the genetic laboratory of the Bogomolets Institute of Physiology of NAS using molecular biological analysis of allele recognition by polymerase chain reaction (PCR) in real time. To assess the economically useful features used an electronic database of SUMS "Orsek". The content of milk components was determined in the laboratory of Sumy National Agrarian University on the equipment Ultrasonic milk analyzer Master Classic. It was found that the animals met the breed standard in almost all indicators of milk productivity. Between animals of different genotypes the difference on separate economically useful signs is revealed. However, in different periods and on different grounds, it varied greatly, and in some cases it was statistically significant. The genotype for kappa-casein did not have a significant effect on live weight in all study periods. Animals with the AA genotype predominated on this trait of animals of other genotypes. At the same time, animals of all studied genotypes in almost all age periods exceeded the breed standard. According to the results of the assessment of the reproductive capacity of animals, it was found that the youngest age of the first insemination is characteristic of animals with genotype AA, and the highest - with genotype BB. The age of first insemination in animals with genotype AA was less than the average for the herd. The live weight of these animals was the largest and was higher than the average for the herd. The average duration of the service period for the herd was 130 days. It was lowest in animals with homozygous BB genotype (P <0.05). Accordingly, the duration of the period between calving and the value of the reproductive capacity were the lowest in homozygous (BB) animals (P <0.05). The level of average milk yield of an animal with the desired genotype (BB) was lower than the average yield of animals with other studied genotypes. They were also inferior to the average indicator of the herd. The level of milk yield of animals of all genotypes was higher than the breed standard. It was found that the average fat content in the milk of animals of homozygous genotypes AA and BB slightly prevailed over animals with heterozygous genotype AB. Animals with the BB genotype (p <0.05) were statistically significantly superior in protein content. Compliance with the breed standard in terms of fat content in milk is positive, and only homozygous (BB) animals met the standard in terms of protein content. In terms of dry matter content, dry nonfat milk residue, casein, animals with homozygous BB genotype were preferred. In terms of lactose content, animals with the AA genotype were preferred. It is proved that the formation of herds with BB genotype for kappa-casein will not have a negative impact on the economically useful characteristics of animals. Key words: genotype, kappa-casein, live weight, reproductive capacity, milk productivity.

POTATO SELECTIVE BREEDING FOR SUITABILITY FOR INDUSTRIAL PROCESSING FOR FOOD PRODUCTION

At the Research Institute of Potato-breeding of Sumy National Agrarian University, using own potato varieties as basic forms, 23 promising hybrids were obtained according to the main economically valuable traits (yield – up to 50 t/ha, starch content – 22 %, starch yield – up to 8–10 t/ha). Based on the results of the technological assessment, 35 % of hybrids of the early and medium early ripening groups with a high (28–30 %) dry matter content and low (0.2–0.4 %) reducing sugars content turned out to be the most suitable for industrial processing into potato products. The potential maximum yield of dried potato production was up to 27.7 kg from 100 kg of raw materials, crispy – up to 44.4 kg, which is almost 20 and 10 % higher than the established quality standard. Providing the processing industry with high-quality raw materials in the early stages is one of the factors in increasing the efficiency of enterprises and unloading them in
 the most stressful autumn period.

 Conclusions. It was found that the most sensitive to the preparation “Sukhodez” were the culture of Salmonella enteritidis – at a rate of 25 g / m2 and action on concrete and wooden surfaces, the disinfectant inhibited the growth of the culture when exposed to 5 hours, and at a rate of 50 g / m2 – for 2 years. Staphylococcus aureus was the most stable bacterial culture, so at a rate of 50 g / m2 on concrete and wood surfaces, bacterial growth was inhibited for 4 and 5 hours, respectively. At the same time, in the study of fungicidal properties, “Sukhodez” showed a fungicidal effect on Candida albicans when applied to a concrete surface at a rate of 50 mg / m2 for 3 hours, when applied to a wooden surface – for 4 hours.
 In general, at a rate of 75 g / m2, “Sukhodez” has an instant bactericidal and fungicidal effect on bacteria and fungi applied to concrete and wooden surfaces

Monitoring of parasitic diseases of dogs

During the study, dogs were diagnosed with the following helminthic diseases: toxocariasis, echinococcosis, uncinariosis, trichuriasis, capillariosis, dipilidiosis, which took the form of mono and mixed invasions.
 The aim of this study was to identify the intensity of helminth infestation of dogs of different ages and methods of keeping.
 Materials and methods. Experimental studies were conducted during 2018–2020 on the basis of the laboratory “Innovative technologies and safety and quality of livestock products” and “Veterinary Pharmacy” of the Department of Veterinary Examination, Microbiology, Zoohygiene and Safety and Quality of Livestock Products; epizootology and parasitology of the Faculty of Veterinary Medicine of Sumy National Agrarian University.
 In cities and villages, faecal samples were taken from dogs, taking into account the method of keeping (tethered or untethered) and their use (office, hunting, decorative, etc.), which were placed in airtight containers, labeled samples and sent to the laboratory for the research.
 The object of clinical and laboratory research were dogs aged one to seven years, admitted to veterinary clinics in the period from 2018 to 2020, with suspected helminthic diseases. Testing of dogs was performed by collecting medical history and clinical examination.
 Results. According to the results of the research, it was established that among helminthic diseases during 2018–2020 the following diseases were registered: toxocariasis, cestodes, uncinariosis of dogs. Among the blood-parasitic diseases for the period 2018–2020 were diagnosed with heartworm disease, babesiosis of dogs.
 Among ectoparathyroidism, the laboratory diagnosed demodectic mange, otodectosis, canine sarcoptosis, and carnivorous syphonepterosis. A total of 513 surveys were conducted in 2018, of which 80 were positive; for 2019–509, of which positive – 58; for 2020 – 488, of which 62 are positive.
 Conclusions. Intestinal helminthiasis has been found to account for the lowest proportion (11 %) of carnivorous parasitic diseases compared to blood parasitic diseases (19 %) and ectoparasitosis (70 %), but they are of great interest for study because of their significant epidemiological significance and may be the cause of disease in humans.
 It has been proven that helminthic diseases of dogs run as mixed invasion, and a minority of cases 31.7 % of cases run as mono invasion. Of the total number of patients with helminthic diseases, 73.4 % of the total number of animals were accompanied by other diseases of infectious and non-infectious ethology

Effect of feeding of chelated zinc form on security, productivity and slaughter parameters of broilers

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented.
 The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc.
 Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated.
 Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05).
 Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

Defining the Components of Student Training for Participation in International Programs

The integration of Ukraine into the European and transatlantic community is increasingly becoming more dynamic and vital. Ukrainian scholars, students, and professionals establish new diversified educational, business, cultural, scientific contacts in all spheres of life with European countries and throughout the world, which requires a number of special communication and activities skills. This paper investigates the student training process components, such as language learning, social and cultural skills development, psychological training, and patriotic attitude towards Ukraine abroad for developing a specific course for students. The students of Sumy National Agrarian University were surveyed about the ideal state of completing the international programs, both those who participated in the international programs and those who did not, but could assume the challenges they would encounter. The main problems which related to the participation in the international programs were found to be associated with language proficiency and social and cultural skills (about 45%), psychological and cultural adaptation to the foreign environment (about 25%), as well as the attitude towards Ukraine and the ability to represent oneself abroad adequately (about 30%). Many factors could influence the successful participation in international programs. However, we found clear indications that besides the language acquiring the course on preparing for the international programs should also include the social and cultural, psychological, and patriotic components.

University Impact on Regional Development in the Context of Smart Specialisation

Regional development on the basis of smart specialisation entails the involvement of stakeholders in innovation processes such as business, public organisations, local government and academic sectors. Universities are the drivers of a region’s development because they have a broad research base. Using the methodology of the Joint Research Centre (European Commission), the impact of Sumy National Agrarian University on the development of the Sumy Region was assessed by such criteria as its cooperation with stakeholders, innovative infrastructure of the university, development of academic entrepreneurship, and its role in developing the region. The method of collecting qualitative data involved conducting structured interviews with the university administration and relevant departments. The collected data were analysed by content analysis. As a result of testing the methodology, its high level of applicability was noted in the Ukrainian academic space, outside the EU. It is recommended to use the method of assessing the impact of the university on the development of the region during the entrepreneurial discovery process, which follows the definition of priorities for the development of the region in the context of smart specialisation. The recommendations were given on the revival of cooperation with stakeholders, possible ways of developing academic entrepreneurship and building innovation infrastructure. The results of the research presented in this article may be used in university promotion within the region and the country as well in the context of smart specialisation. Policy makers may use the research results in order to provide regional innovation policy.

In particular, in the issue of cataloging and work on the corporate project "AgroCARS" on the exchange of analytical bibliographic records of periodicals and continuing publications on agricultural topics, the formation of an electronic distribution resource of agricultural libraries of Ukraine online. The corporate interaction of the National Scientific Agricultural Library with the subordinate network for compiling bio- and bibliographic indexes is considered. Thus, the dynamics of the formation of indexes of the series "Academicians of NAAS", "Correspondent Members of NAAS" and "Bibliography of agricultural scientists" were analyzed. The cooperation of agrarian libraries on the formation of a bibliographic index series of foreign publications entitled "Foreign agricultural book in the funds of NSАL NAAS, SRI and universities of agricultural profile" was studied. In total, 11 bibliographic indexes were prepared and published in this series. The importance of raising the professional level of librarians, especially those who take part in corporate interaction, is noted. The role of the National Scientific Agricultural Library in improving the professional competence of librarians has been clarified, first of all, through conducting annual advanced training courses for librarians and a conference. The work carried out by the Main Libraries of Territorial Associations of Agricultural Libraries in matters of corporate interaction is reflected. In particular, scientific libraries of Sumy National Agrarian University, Zhytomyr National Agroecological University, Vinnytsia National Agrarian University and Lviv National Agrarian University. The problems that arise in the "participants" of corporate interaction and ways to solve them are presented.

Fostering Media Literacy Skills in the EFL Virtual Classroom: A Case Study in the COVID-19 Lockdown Period

This investigation highlights the ways and means of students’ formation of media literacy skills under the conditions of total and emergent distance learning in the lockdown period of the COVID-19 pandemic. The case study involved 138 first-year students from Sumy National Agrarian University, Ukraine, who studied English as a foreign language (EFL). Analysis, synthesis, and generalization of scientific data were conducted to determine the requirements and materials for the survey. Media literacy of the participants in the experimental group was developed through performance of a series of social media projects, critical analysis of social media texts, and creation of social media content. Pedagogical observation and expert estimation were employed to obtain qualitative results of partiucipants’ progress during practical classes and extracurricular activities. Psychological techniques and mathematical methods were employed to measure and assess the quantitative data of the experiment. The outcomes of the study revealed the positive dynamics of the development of reflective-evaluative, collaborative, and searching-creative skills of participants in the experimental group as well as improvement in their English proficiency. The result of this study is potentially appropriate for educators who are interested in the application of media technologies in foreign-language teaching.

Determination of Toxicity of Experimental Disinfectant

Excessive use and abuse of disinfectants over the past century has created problems associated with the emergence of resistant microorganisms. In addition, there is always a potential risk to human and animal health, as the use of aggressive disinfectants can lead to diseases. The purpose of the study was to investigate the toxicity of an ex perimental disinfectant to determine the possibility of its use in the presence of humans and animals. Study material – an experimental product (water-soluble disinfection powder). Experimental studies were conducted at the premises of a certified vivarium of the ECOMEDCHIM regional centre of Sumy State University and Sumy National Agrarian University. Acute toxicity of the preparation was studied on 30 white mice weighing 19.5±1.0 and 15 white rats weighing 200±15.0 g. Determination of toxicity by prolonged oral administration was studied in two analogous groups of white rats, 6 animals each with a bodyweight of 185±10.0 g. The effect of the preparation on the state of internal organs was evaluated by comparing relative mass coefficients. The local irritating effect of the preparation was determined by skin applications on 10 rabbits weighing 2.97±0.3 kg. The disinfectant, when administered orally once at doses of 1,250, 2,500, and 5,000 mg/kg of body weight, did not cause the death of experimental mice and rats. When administered orally for 30 days at a dose of 2,500 mg/kg of body weight, the disinfectant did not cause any negative and toxic effects on the body of experimental rats, did not affect the growth and development of rats, and did not cause changes in the relative mass of internal organs. It was found that the average manifestation of erythema in rabbits is 2.46. According to the study results, it was found that the disinfectant can be classified as Hazard Class 4 according to the international standard GOST 12.1.007-76, or Category 5 according to the international global classification Global Harmonised System (GHS) (LD50 with oral administration exceeds 5,000 mg/kg of body weight). The results obtained give grounds to assert the possibility of using an experimental disinfectant in the presence of humans and animals
