The state of development of dairy cattle breeding in Ukraine for the period of 2011–2016 was analyzed. The trends of livestock changes, volumes of milk production depending on regions, forms of organization, breeder's membership, breeding and breeding work, influence of genetic and paratyphoid factors on indicators of development of the industry are determined. An analysis of the location of dairy cattle, its concentration, organizational forms of milk production shows significant differences between regions, both in terms of the number of dairy herds and milk production volumes. The largest concentration of cows' livestock in agricultural enterprises is observed in the northern and central regions, in particular, Poltava, Cherkassy, Sumy, Chernihiv, Khmelnytsky oblast. Large agricultural enterprises are more cost-effective than small ones, but the last ones during 2010–2016 still prevailed in the total number of agricultural enterprises - more than 50%. The number of cows of diary and diary-meat breeds decreased almost twice (from 5431 thousand in 2000 to 2736,5 thousand in 2010), and in agricultural enterprises and farms – in four times (correspondingly from 2475 to 604.6 thousand goals). Despite the simultaneous growth of 71.6% of the average cow supply (from 2359 kg – 2000 to 4049 kg – 2009), gross milk production, after some growth until 2005, in 2009 decreased by 13.5% comparing to 2001. The same trend in the dynamics of livestock population continued in the next five years. The number of cows of Ukrainian Black-and-White diary breed as of 01.01.2016 in the control herds decreased to 68181 or 11217 heads, Ukrainian Red-and-White dairy – by 8677 and Ukrainian Red diary – by 4110 heads. At this, gross milk production increased from 2216,6 tons in 2010 to 2705,6 tons in 2016. It should be emphasized that the increase in milk production occurred only in agricultural enterprises due to the growth of productivity of cows from 3975 kg in 2010 to 5643 kg in 2016, that is almost twice. An analysis of the structure of milk production in agricultural enterprises shows the gradual increase in production volumes by large farms, which is a positive trend in terms of milk quality, economic efficiency of its production, and their development as more investment attractive. An important factor in the growth of milk production is the breeding stock of cows. Over the past 5 years, the total number of breeding cows has decreased from 153.6 thousand heads to 128.2 thousand, that is on 12 per cent. The reduction in the number of cows applies to all breeds, but most of it occurred in Red dairy breeds (16.3%). The milk yield of the cows of breeding herds of new domestic breeds grew in all breeds and made up 6613 kg of milk in Ukrainian Black-and-White diary breed with a fat content of 3.70%, protein 3.27%, Ukrainian Red-and-White dairy breeding, respectively 6357; 3.76; 3.26; Red diary – 5963; 3.87 and 3.29. An equally important problem in the development of dairy cattle breeding in Ukraine is the low level of reproduction of animals against the background of reducing the number of livestock and increasing its productivity. This is confirmed by the low yield of calves in farms of different categories. So for 2016, according to statistics, he was 70 calves per 100 cows. One of the factor that reduces the calving out is the natural biological antagonism of milk yield and reproductive capacity of the cows. Growth in milk yield of cows in breeding flocks with an increase in the heredity of the Holstein breed led to a decrease in the yield of calves per 100 cows to 68.7 heads (in 2010). The duration of productive use has the opposite tendency - in newly created domestic breeds it extends to 3–4 lactations, in Holstein – up to 1.8–2.0 lactation. The level of heifer cultivation is a major paratypic factor affecting the formation of their productive features. The intensity of breeding heifers and heifers does not fully meet the requirements of the standard domestic breeds for their live weight. From 2019, 33498 heifers in only 45.7% – 71.5% of heads, average live weight in 6 months corresponded to the breed standard, in 12 months – 61.1–82.1 and 18 months old – 63.1–73,9%. In a number of even breeding farms, the average daily gain of heifers at 6–12 months of age, during the formation of the organism, is 550–625 g. As a rule, in such farms they do not reach a high level of milk productivity. The ways and methods of reforming dairy cattle for the period up to 2025 should be formed on such bases: - in organizational terms, focusing on the expansion of milk production in large farms, which is positive in terms of the use of modern intensive technologies, the economic efficiency of its production, the attractiveness of investment; - the revival of the national selection system, which corresponds to the best examples of its organization in European countries; - domestic dairy breeds must be established as the basis of domestic dairy cattle breeding, which correspond to the conditions of their breeding and quality of products according to a set of features; - amendments to the Procedure for using the funds provided for in the state budget, directing them to implementation of the breeding program in livestock, approved by the Cabinet of Ministers of Ukraine. Execution of the proposed measures will allow to achieve the volumes of production of milk and dairy products provided by the Program.

The aim of our research was to conduct a retrospective analysis and to study the current state of the subjects breeding Znamensk intrabreed type of Polessian Beef breed and to assess main economically useful traits and genealogical structure. Material and methods. Research of productive and economic activity of breeding farms has been carried out based on the electronic database of State Register of Breeding Subjects in Livestock for 2003-2016. Analysis of the number of breeding animals, distribution of cows by age, animals’ live weight, milk (as a calf’s live weight at the age of 7 months) and reproductive abilities has been performed based on breeding account (form №7-myas) for 2010, 2012, 2014, 2016. Results of research. The most breeding farms meet the minimum requirements of the target standard of Znamensk intrabreed type on the main quantitative traits of animal productivity. "Kolos" АLLC, Kirovograd region and «Agrikor Holding" LLC, Chernihiv region were the most numerous. High realization of genetic potential of meat productivity (daily gain of live weight above 1000 g) was observed at animals in «Kolos» АLLC and «Sharivske» PE. There have been sold 222 head of the breeding youngsters for 13 years. The greatest number of animals was observed according to annual reports in 2012. It can be explained by the number of subjects conducting the selection and breeding work with the intrabreed type. The share of cows did not exceed 43.0% (2012), bull – 1.5% (2010), calves of different gender and age groups – 66.1% (2014). 85.5% of all the available breeding stock (5369 head) was approved and 67.8% corresponded to elite and elite-record classes. Live weight of the approved cows has increased by 7.5% at the age of 3 years, 9.7% at the age of 4 years and 11.1% at the age of 5 years since 2010. Differential for live weight of cows at the age of 4 and 5 years was 9 and 11 kg on the average. There was adequate number of animals, live weight of which was in a wide range, that is from 551 kg and above. So, such cows were 111 head in 2010 and 234 head in 2016. These cows realise genetic makings of high productivity sufficiently and they are material for selecting the best representatives of Znamensk intrabreed type. Gradual increase of milk ability was noted from 2010 till 2016 after the first calving by 13.7%, the second – 12.2, the third – 11.7, and by 11.9% on average. Differential for milk ability of cows was 5 kg (2010, 2012), 11 kg (2014) and 2 kg (2016) on average. Average calving interval of cows for the period are oscillatory in nature and didn’t exceed 420 days during 2010-2014. Gradual increase of age at first calving of heifers by 101 days was observed from 2010 to 2014 with reduction to 824 days for next two years. It should be noted violation of course of cows’ and heifers’ calvings, it was 29 and 36 cases in 2010 and 2012 respectively, whereas in subsequent periods, these values were significantly lower or non-existent. It may indicate a high level of veterinary services and compliance of technologies of feeding and management. Efficiency of beef cattle-breeding depends on the growing of calves. Analysis of the results shows that live weight of calves at the age of 210 days has increased in each investigational year. The values are oscillatory in nature between 8 and 15 months. Sexual dimorphism was confirmed and proven – bull-calves had higher growth rate compared to heifers. Significant reduction in the livestock number of the approved bloodlines and their absence in some cases (Radyst 113 and Darovanyi 400) was observed. This is due to the increased share of Polessian Beef and Charolais bulls used for reproduction. There were 139 cows, 27 heifers and 13 calves in group belonging to Polessian Beef and Charolais bloodlines in 2012, whereas in 2014, 281, 193 and 18 respectively, representing 81% of the total population. Conclusions. The research revealed that livestock of the type were concentrated in «Agrikor Holding» breeding farm, Pryluky district, Chernihiv region with a total of 922 head, including 348 cows. Productivity of animals by the valuation results at the beginning of 2016 (live weight, milk ability, reproduction) significantly increased. Current genealogical structure of Znamensk intrabreed type was represented by bulls belonging to Polessian Beef and Charolais bloodlines, share of which was 81%.

The genealogical structure of Ukrainian Red-and-White Dairy cattle has been represented by 12 tested and approved farm bloodlines, ancestors of which are Holstein bulls of red colour (Improver 333471, Hanover 1629391, Regal 352882, Nahit 300502, Inhancer 343514, Cavalier 1620273), Montbeliarde (Supreme 33470, Mayerdel 1599075, Dynamic 359742, Dairymen 1672325, Shevrey 6241) and Ayrshire (Don Juan 79601) breeds. Selection process ensures constant movement of lines and inheritance of some lines moves to historical and statistical work and is used for analysing the successful selection and the best combination, whereas, the other ones improve genetic value of economically useful traits of productivity in the next generations and, therefore, they are progressing and developing. Qualitative features of related groups by the breeding traits are a basis on which we should concentrate all the range of selection and breeding work at each stage of breed improvement because a line and a breed, in the classical sense, are inseparable concepts of a large conglomerate of a population, which has been created by many scientists and practitioners.  The aim of this work was to analyse the current state of genealogical structure of Ukrainian Red-and-White Dairy breed for the breeding stock and their belonging to breeds and lines. The materials of research for characteristics and analysis of genealogical structure of Ukrainian Red-and-White Dairy cattle were breeding accounting data on the form №7-mol. In total the data for 74 breeding farms of 15 regions of Ukraine were used. Belonging to breeds, lines and data for assess by origin and progeny were determined on the basis of SUMS "Orsek", Institute of Animal Breeding and Genetics nd. a. M.V. Zubets of National Academy of Agrarian Science of Ukraine. The availability of frozen semen of the Ukrainian Red-and-White Dairy bulls admitted to reproduce breeding stock was determined according to the annual catalogues for 2015 and 2016.2016. Modern genealogical structure of the breeding stock is formed due, in addition to Ukrainian Red-and-White Dairy breed, Red Holstein, Jersey, Montbeliarde and Simmental breeds. The total number of females is 48,279 animals, including 24,264 cows and 24,015 heifers originating from 375 bulls. The share of Simmental bulls involved in the selection was 11% (42) with the number of 881 animals. The breeding stock from Holstein bulls (207) is 82%, whereas, the share of 101 bulls of Ukrainian Red-and-White Dairy breed is only 15%. Modern genealogical structure of the breeding stock is formed due, in addition to Ukrainian Red-and-White Dairy breed, Red Holstein, Jersey, Montbeliarde and Simmental breeds. The total number of females is 48279 animals, including 24264 cows and 24015 heifers originating from 375 bulls. The share of Simmental bulls involved in the selection was 11% (42) with the number of 881 animals. The breeding stock from Holstein bulls (207) is 82%, whereas, the share of 101 bulls of Ukrainian Red-and-White Dairy breed is only 15%. Genealogical structure of breeding stock of Ukrainian Red-and-White Dairy breed has been represented by 15 bloodlines. The fewest (71 animals) was obtained from three bulls Magnet 1560362, Majority 1599069 and Maximus 297414. The 10%-share (4712 animals from 57 bulls) from the total number was genealogical structure of six approved farm bloodlines of the Ukrainian breed. For breeding evaluation of origin (pedigree index) 17 Holstein bulls had the average value – +27.6, including seven bulls with negative PI-595 and 10 bulls with positive PI + 463.5. For bulls of Simmental and native breeds, the indices were 6 (-122), 2 (+264), 4 (-315) and 12 (+587.8), 1 (-264) 11 (665) respectively. Discrepancy (2 of 35 investigated bulls) with the minimum requirements (30 first-calf heifers in 4 herds) concerning the evaluation of bulls by progeny makes impossible to obtain objective information about breeding value of bull. In our opinion, the factors which, can make a difference in the genealogical structure of Ukrainian Red-and-White Dairy cattle are to increase the share of bloodlines of the native breed through catalogue of admitted bulls to reproduce breeding stock, which is compiled by the materials of pedigree enterprise of Ukraine. Based on materials of 2015, during the mating period 59 bulls of 15 bloodlines were involved, including 38 approved bulls which share of sperm was 84%. In 2016, the available frozen semen of bulls of the native breed decreased by 674.5 thousand doses which was 81% compared to presented one in 2015. Conclusions. Current genealogy of Ukrainian Red-and-White Dairy cattle has the ramified system represented 42 Simmental bulls of 15 bloodlines, 207 Holstein bulls of 19 bloodlines, 101 native bulls of 15 bloodlines and two Jersey and Montbeliarde bulls. In modern realities of selection and breeding work, concern is widely use of Holstein sires in the reproduction of breeding stock of Ukrainian Red-and-White Dairy that each year minimizes the share (now about 10%) in the selection of approved bloodlines and "genetic identity of native breed". The perspective of involving bulls and with it the widespread use of the method of breeding by bloodlines in Ukrainian Red-and-White Dairy cattle is too illusory, whereas every year the availability of semen of the admitted bulls in sperm banks of Ukraine decreases (only the last year by 81%), and inability (with requirements) for the evaluation by progeny of those bulls which have already had pedigree index.
