At the present stage, the development of dairy farming needs to focus on increasing the livestock population with high productive indicators in the large-scale sector. In the period from 2000 to 2020, the number of cows in Ukraine decreased by 2.8 times (from 4958.3 thousand heads on 01.01.2001 to 1788.5 thousand heads on 01.01.2020), and in agricultural enterprises – by 4.2 times (from 1851.0 to 438.6 thousand heads respectively). An important factor in the growth of the large-scale sector should be the revival of the national selection system. Therefore, the issue of scientific substantiation of the organizational principles of effective management of breeding dairy cattle breeding is now of particular urgency. The purpose of the article is to carry out an evaluation of genetic resources of breeding dairy cattle Ukraine. The research was conducted on the observation materials of the State Statistics Service of Ukraine, the International Committee for Animal Recording, the State Register of subjects of breeding business in livestock breeding by using statistical methods. Cattle breeds are differ according to economic indicators of useful traits of animals, including the level of productivity, which significantly influences the economic efficiency of production. According to ICAR (The International Committee for Animal Recording), cows of the Holstein breed remain the leaders, whose productivity for the 305 days of lactation is at the level of 9–11 thousand kg of milk. Such achievements are the result of a long intensive breeding work aimed at increasing milk production. Among other breeds, which cow' productivity approachs the animals Holstein breed, Ayrshire (up to 9.0 thousand kg), Braunvieh, Montbeliarde, Fleckvieh, Norwegian Red, Swedish Red, Jersey (7.0–8.0 thousand kg) are next. A number of breeds are distinguished by qualitative features of dairy productivity. For example, the fat content in milk of cows of the Jersey breed of Canadian breeding is 5.1%. The milk productivity of these breeds is lower than Holstein dairy cows. But they have significant benefits in functional traits such as high reproductive capacity, extended duration of economic use, high payment of feed by the resulting products, which increases their competitiveness to the level of animals of the Holstein breed. In Ukraine, the highest milk productivity is Holstein (8965 kg), Fleckvieh (8877 kg), Ukrainian Black and White Dairy (7486 kg) and Ukrainian Red and White Dairy (6997 kg). Currently, in 344 breeding herds, 137.8 thousand cows are kept, which is one third less than 10 years ago. The most numerous is the Ukrainian Black and White Dairy – 68.829 purebred cows, or 49.9% in the structure of dairy cattle breeding herds. The share of Holstein – 25.2%, Ukrainian Red and White Dairy is 14.4%. It should be noted the extremely insufficient number of cows of the active part of the livestock (breeding stock-rearing farms that are certified as subjects of the tribal affairs and conduct breeding records) – 29.5% of the number of cows kept in agricultural enterprises, and 7.7% – at farms all categories. For example, in Israel (the world leader in the cows’ milk productivity in level about 12 thousand kg per cow) it is more than 90%. In other countries with a developed dairy industry, this figure is at 90% – in Denmark, 86% in Sweden, and 70% in Canada. The low proportion of the recorded dairy livestock in Ukraine greatly complicates the process of improving high-yielding herds. Over the past ten years, the number of breeding stock-rearing farms in Ukraine has doubled. Among them there was a tendency for livestock consolidation. Average number of cows in herds the breeding stock-rearing farms was: in 2007 – 241 heads, in 2012 – 334, in 2017 – 373, in 2019 – 401. In 2007–2019, as a result of ongoing concentrations of livestock, the average size of a purebred dairy herd increased almost one and a half times, which, due to the scale effect, made it possible for enterprises to reduce production costs per unit. The average milk yield of purebred cows in industrial enterprises increased from 4606 kg in 2007 to 7653 kg in 2019, or almost one and a half times. Due to the effect of the factor of natural biological antagonism on the milk productivity and reproductive capacity of cows, the raising of productivity with an increase in the heredity of the Holstein breed has led to a decrease in the calving output of 100 cows, and a decrease in the length of the commercial use of cows. This trend is also characteristic of all newly created dairy breeds. In particular, from Ukrainian Black and White Dairy cows the calving output per 100 cows decreased from 82.8 heads in 2006 to 77.4 in 2019; Ukrainian Red and White Dairy respectively from 82.2 to 69.5 calves; Ukrainian Red Dairy, where the proportion of the heredity of the Holstein breed is slightly lower than the first two, the calving rate dropped at lower pace. According to the results of dairy cattle recording, among the domestic breeds the highest milk productivity is in the Ukrainian Black and White Dairy cows – 7364 kg with a fat content of 3.74%, protein 3.22%; Ukrainian Red and White Dairy – respectively 6989; 3.78; 3.27; Ukrainian Red Dairy – 6549; 3.90; 3.26. Domestic breeds on genetic potential are at the level of the best European analogues, and according to indicators of reproduction and health they prevail them. Consequently, the breed of cows is an important factor in the economic efficiency of dairy cattle-breeding. Due to the long intensive selection work on cattle breeds, the milk productivity of cows in developed livestock countries has reached levels of 8.0–10.0 thousand kg and more for 305 days of lactation. The number of cows in breeding farms in Ukraine for 2006–2019 has decreased by 38 thousand head, or by 22%. The average milk yield of purebred cows in industrial enterprises increased from 4606 kg in 2007 to 7653 kg in 2019, or almost one and a half times. But the extremely insufficient number of cows of the active part of the livestock greatly complicates the process of improving high-yielding herds. In the breeding structure of pedigree dairy cattle, animals of Ukrainian Black and White Dairy (49.9%), Holstein breeds (25.2%) and Ukrainian Red and White Dairy (14.4%) prevail.

The current situation in the dairy sector of Ukraine has become threatening to the economic security of the state. During the years of independence there was a significant reduction in the number of dairy herds (from 8.5 million to 1.7 million), the production structure of dairy cattle changed from mainly large-scale production (where 74% of cows were kept in agricultural enterprises in 1990) to small-scale one (when now 75% of cows are kept in households). Due to the systematic reduction of the dairy herd and the reduction of its own full-fledged fodder base because of the reorientation of the agricultural sector to more marginal crops, the gross production of raw milk and its receipt for industrial processing is reduced. On average, milk production in Ukraine decreases annually by 1.5%. The purpose of the article is to form scientific and methodological approaches to the profitable use of genetic resources of dairy farming in Ukraine in modern conditions. Research methods: general scientific (analysis, synthesis, classification), content analysis of scientific sources and legal documents, statistical, economic and mathematical. Research results. The situation in the industry is currently showing signs of a systemic crisis, when negative phenomena have spread to all levels of economic activity. Therefore, there is a need for a comprehensive analysis of the current state of the industry to identify factors and reserves to increase the profitability of the use of genetic resources of dairy farming, which is proposed to be carried out in stages: 1) economic assessment of the effectiveness of the dairy industry at the macro level of economic activity (in the country, region); 2) at the meso level (by breed of genetic resources of livestock); 3) at the micro level (in economic entities (agricultural enterprise, peasant (farmer) economy, personal economy)). The use of genetic resources of dairy farming can be considered profitable when all the above parameters of efficiency are achieved at the macro-, meso- and micro-levels of economic activity. This comprehensive approach makes it possible to draw conclusions about the achievement of individual targets (production, economic, social, environmental, etc.) and the prerequisites for ensuring the sustainability of the dairy industry as a whole. Ensuring the sustainability of the industry as a production system requires a focus on key areas: management system, breeding work, technology of maintenance and feeding. The introduction of the achievements of modern selection science is especially noticeable in the system of measures to ensure profitable livestock farming. It is the parameters that describe the stable properties of the animal, characterize the genetically determined resource potential, which has a decisive influence on the implementation of all other types of resources involved in production (land, labor, intelligence, capital) and the degree of their payback. Therefore, an important area of state support for the profitability of the use of genetic resources of dairy farming should be the financial support of the national breeding system. Growth of milk production in a short time can be achieved in the largesale sector by increasing the number of dairy cows of specialized breeds with high genetic productivity potential, which is positive in terms of modern intensive technologies, economic efficiency, attractive investment. Conclusions. Ensuring the sustainable development of the industry in condition of livestock reduction requires a comprehensive analysis of its current state, which must be conducted at all levels of economic activity to identify factors and reserves to increase the profitability of the use of genetic resources of dairy cattle. The criteria for the effectiveness of the development of the dairy industry is the achievement of both individual parameters (production, economic, social, environmental, etc.) and its stability as a whole. In the system of measures to ensure the profitable use of genetic resources of dairy farming is important to implement the achievements of modern breeding science. This parameters that describe the stable properties of the animal, characterize the genetically determined resource potential, which has a decisive influence on the implementation of all other types of resources involved in production (land, labor, intelligence, capital) and the degree of their payback. Therefore, an important area of state support for the profitability of the use of genetic resources of dairy farming should be the financial support of the national selection system.

The global dairy sector has been significantly impacted in recent years, with experts assessing the consequences as a serious threat to the food security of the world's population. The biggest destabilising factors for the industry were the effects of the pandemic, war, inflation and high energy prices. Despite the steady increase in demand for milk, there is currently no trend towards a recovery in production growth. Dairy producers are under constant pressure from the above factors, resulting in lower margins, difficult access to competitive capital, and constant adaptation to new regulations. In the current political, economic and climatic conditions, one of the possible ways to increase the profitability of the dairy industry as a major incentive to increase production is the widespread introduction of innovative technological approaches to milk production. The purpose of the article is to assess the state and trends in the implementation of innovative technological solutions in dairy farming in Ukraine on the example of Ukrainian breeding dairy farms. Research results. In order to ensure the survival of the national dairy industry during the active military phase, as well as its rapid development in the post-war period, created a Roadmap for the restoration of the dairy industry. The Roadmap is primarily aimed at ensuring sustainable long-term development of the dairy industry; creation and operation of highly efficient and financially sustainable dairy farms; stimulating the construction of modern dairy enterprises with widespread introduction of innovations aimed at increasing the international competitiveness of the industry. Our research has shown that in recent years, the dynamics of modernisation processes in Ukrainian dairy farming has accelerated. In particular, in the Holstein herds, the productivity of cows kept in dairy complexes increased by 1882 kg per cow, or 470 kg per year on average, in 2016–2020. At the same time, increasing the efficiency of milk production through the introduction of innovative technological solutions will result in a mega-trend of farm consolidation in the future. For example, in the US, 50.3% of milk is produced at industrial large-scale dairies with more than 1.000 cows, where the latest science and technology is used. The influence of the factor of production concentration on the efficiency of the use of breeding animals of dairy and dairy-meat cattle breeds was studied. The average number of cows in the controlled breeding herds of dairy breeds in Ukraine (n = 350) in 2019 was 400 cows. The average milk yield per cow was 7.540 kg. According to the results of the analysis, as the number of cows in the farms grows, economic indicators such as revenue, profitability, and profitability increase. Conclusions. In recent years, a quarter of breeding farms for the most numerous specialised dairy breeds have been involved in the innovation process in pedigree dairy cattle breeding, with more than 50% of the number of breeding cows of these breeds concentrated there. The small herds used traditional technologies for keeping and using cows. The introduction of the latest innovative technological solutions for industrial milk production ensures an increase in revenues from its sale due to the growth of cow productivity. As the concentration of cows increases, the industry's performance indicators, such as milk yield, feed intake and the intensity of land use, are also increasing. The industry's profitability is increasing from 14.7% to over 24.2%. When creating new livestock complexes in the post-war period, the best international and domestic experience of the industry should be taken into account. The development of the dairy farming sector should be aimed at breeding specialised dairy cattle breeds and introducing innovative technologies for their maintenance, feeding and operation. Domestic specialised dairy breeds are at the level of the best European analogues in terms of productivity in industrial dairy complexes, and are superior in terms of reproduction and health, are economically viable and should become the basis for further development of the dairy cattle industry in Ukraine.
