The efficiency of the use of cattle of one or another breed is determined both by the level of milk productivity and the ability of the cattle to reproduce. At the same time, the future reproductive capacity, milk yield and duration of economic use to a large extent depends on the live weight and age when heifers insemination. The purpose of research. Study the effect of live weight and age at the first insemination on the milk productivity cows of Ukrainian red dairy breed. Methods. The research was carried out in the breeding plant of the state enterprise "Elite" of the Kirovograd state agricultural research station of NAAS on 697 cows of Ukrainian red dairy breeds, which were found during 2004–2014. Milk productivity of cows and their live weight and age at the first insemination were investigated according to the materials of the primary zootechnical and pedigree records. The degree of connection of live weight and age at the first insemination with milk productivity was estimated by correlation analysis. One-factor dispersion analysis determined the level of influence of the age of the first insemination and live weight on the productivity of cows. The calculations were made using methods of mathematical statistics using the software package "STATISTICA-6.1". Results of research. By the analysis of milk production on experimental cows, determined, that its level depends on the live weight of animals at the first insemination. Therefore, cows with live weight at the first insemination was 420–439 kg, dominated by mercy unique live weight of 380 kg in the first lactation at 244 kg (6242 vs 5998 kg), td = 1,96 for the third – 1069 kg (7465 vs 6396 kg), td = 2,37 by best lactation 498 kg (7916 vs 7418 kg), td = 2,03, significance level for all lactation (P < 0,05). To the milk fat, accordingly, the predominance was 13.2 kg (260,2 vs 247,0 kg), 22,9 (309,5 vs 286,6 kg) and 21,0 kg (325,1 vs 304,1 kg), the difference is close to the true values. The peers with a live weight of 400–419 kg and 440 kg and more also yielded in the first milk yield. The difference the milk I, III and the best lactation was 72 kg, 219 kg and 91 161 kg, 674, 589 kg for milk fat yield 5 kg, 10.3, 6.1 kg and 11.5 kg, 28.8, 19.5 kg, respectively. Due to the lesser number of animals, the vast majority of values did not reach a reliable level. Studies of milk productivity of cows, depending on the age of the first insemination, showed that its cow was the highest, which were counted at the age of 455 days. The lowest rates of dairy productivity were the animals that were fertilized at the age of 606 or more days. Correlation analysis found the highly reliable of feedback age insemination of cows milk yield in the first three lactation (-0,25 ... -0,37). Similar patterns of feedback for somewhat lower correlation coefficients are noted with the release of milk fat (-0,23 ... -0,33). Coherence of live weight at the I insemination and follow-on milk production was significantly lower (compared with age insemination) in absolute value, for only a certain level of first lactation milk yield and milk fat yield (P < 0,05). The significant influence of the investigated factors on milk yield of cows is established. Thus, by milk yield and milk fat and protein for 305 days of lactation cows power of influence age of first insemination exceeded 50%, the fat and protein in milk index of potency is 32 and 30% by high-confidence values for milk yield and yield of milk protein and fat . Somewhat lower than 20 to 33%, the effect of live weight on the first insemination was shown on the performance of cows. Сonclusion. The heifers of the Ukrainian Red dairy breed in conditions of the Central region of Ukraine advisable to fertilize at the age of 455 days, or 14,5–15 months, when they reach the living weight of 420–439 kg. The revealed feedback of the inseminative age and milk productivity can be explained by more intensive growth, better development and economic rapidity of the previously diced heifers and its should lead to intensive rearing of young animals. Determined, that the force of age-old influence of the first insemination on the lactic productivity of the cows exceeds 50%, the live weight reaches from 20 to 33%. Discovered tendency also confirms the expediency of intensive growth of repair heifers.

The influence of bullock`s different breeding value for reproductive ability and milk production of their  daughters were investigated. Established that the age of first productive insemination of heifers Ukrainian black spotted milk breed, was 17.5–18.6 months and age of first calving – 26.6–27.8 months. Heifers` live weight at the first insemination was 361.4–407.1 kg. During first lactation the highest productivity had daughters from parents with breeding value by milk yield more than 801 kg. In the first lactation wasn’t found significant difference in duration service-period and interparturition-period for cows derived from progenitors with different breeding value. In the second lactation best indexes in duration service-period and interparturition-period for cows derived from progenitors with breeding value by milk yield 601–800 kg and more than 801 kg. In the third, the highest lactation, these indexes were best for cows derived from progenitors with breeding value by milk yield 601–800 kg. The difference in milk yield during first lactation between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s  with breeding value 401–600 kg was 292 kg. The difference in milk yield between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s  with breeding value  with breeding value 601–800 kg  was 660.3 kg. The difference in milk yield between heifers received from progenitors with breeding value by milk yield less than 200 kg and heifers from bullock`s  with breeding value more than 801 kg was  920.8 kg In the second lactation this difference was 589.8 (Р < 0.001), 841.5 (Р < 0.001) і 894.4 (Р < 0.001) kg of milk, in the third, the highest lactation – 754.5 (Р < 0.001), 951.8 (Р < 0.001) і 1335.7 кг (Р < 0.001).

Investigation of the selection methods, used during various stages of the creating the Ukrainian red dairy breed, has an actual significance in the evaluation of the methodology of the breed formation process. A comparative analysis found that the female ancestors of the studied cows according to milk yield significantly differed. With each subsequent stage, bulls-breeders, which were used in the breeding process, prevailed over female ancestors of the previous stage according to the milk productivity. The level of maternity benefit of the parents of the second and third stages was higher than that of the parents of the first stage mothers. However, for fatty milk, the parents of stage I parents had a superiority, compared with the second and third stages. While analyzing the milk yield of mothers of cows, it was found a certain pattern. In particular, the increase in milk in the next stages of the breeding of Ukrainian red dairy breed. According to the productivity of cows-primates, derived from different selection methods, determined by the level of support of female ancestors, the effectiveness of the use of highly heterogeneous selection is established. The difference in comparison with the homogeneous selection for the second and third stages was 462 kg (P > 0.999) and 235 kg of milk, respectively. As for the first stage of  breeding of Ukrainian red dairy breed, the best results were obtained from the use of moderately heterogeneous selection. Its efficiency is confirmed by the highest milk yield of 359 kg (P > 0.95) of milk compared with homogeneous selection. There was a tendency to increase the fat content in milk of animals in the I, II and III stages of the breeding process in a highly heterogeneous selection in comparison with homogeneous selection, the difference was accordingly 0.04%, 0.05% and 0.03%. It should be noted that in the second stage, heterogeneous selection was effective. Along with the abovementioned, there is a general tendency of reduction of fatty milk production in ІІІ stage compared to І and ІІ stages. This is explained by the inclusion in the program of the breeding process of the Ukrainian red dairy breed using the Holstein breeder bulls. Based on the analysis of the data obtained, we have a convincing confirmation of the effectiveness of a highly heterogeneous selection. In the first and second stages of breeding, the prevail of milk fat was 15.4 kg (P > 0.99) and 12.9 kg (P > 0.95) compared to homogeneous selection. Thus, it is logical to increase the level of milk productivity in the studied cows from the first to the third stage of the withdrawal of Ukrainian red dairy breeds with the advantage of using highly heterogeneous selection.

The aim of the research was to study milk production of many factory families of Ukrainian Brown dairy breed and study the influence of origin on the indices of milk yield, duration and effectiveness of lifetime use of cows. Method. For research allocated 9 factory families of Ukrainian Brown dairy breed of State Enterprise «Experimental Farm of Institute of Agriculture of Northern East of NAAS» (Valuty 413, Voli 8369, Laymy 8221, Miry 7209, Ryabuhy 9728, Sujety 6091, Tochky 8169, Chubarochky 7743, Shchepky 4344). Among the indicators of the duration and effectiveness of lifetime use of cows was determined the duration (days) of life, economic use of and of lactation, number of lactations for life, lifetime milk yield and yield of milk fat (kg) average lifetime content (%) fat in milk, milk yield (kg) per day of life, economic use and lactation. The coefficient of economic use was calculated (expression in percent) by the proposed method by Pelehaty M. S. et al. In addition were determined (also in percentage) coefficient of lactation and the coefficient of productive use offered by Polupan Y. P. Milk productivity of the animals was evaluated according to the materials of the primary zoo-technical account. Statistical processing of results of studies was conducted by methods of mathematical statistics using the PC. The results of the research. By analyzing the productivity of cows managed to identify a significant level of specificity and differentiation of families according to the indications. Of the 90 cows accounted for the highest productivity of lactation, 28, or 31%, had hopes of 5.0 thousand kg and above. Most of these cows had family, Miry 7209 (67%), Ryabuhy 9728 (57%), Valuty 413 (55%), Shchepky 4344 (50%), less-Sujety 6091 (36%), Chubarochky 7743 (33%), Tochky 8169 (25%), Laymy 8221 (16%), Voli 8369 (10%). Over a long period of economic use and lactation of animals of Valuty 413 family resulted higher in comparison with other families a lifelong yield. The influence of the origin of cows on the indices of milk productivity and effectiveness for lifelong use was discovered. The origin of the family significantly influenced on milk yield for better lactation and milk yield per 1 day of life. Other indicators were not significant according to the origin, although they had high values (from 5.4 to 26.7%). So we can consider it expedient to work with families to improve the duration and effectiveness of lifetime use of cows. Conclusions. The highest average yield for the first lactation animals is characterized by animals of Ryabuhy 9728 family, the content of fat in milk – by animals of Voli 8369 family. Long average duration and a better efficiency is in the life of the cows of Valuty 413 family. The highest average milk yield in one day life had animals of Valuty 413 family. Animals of Valuty 413 family are allocated at the average value of the coefficient of economic use. Optimal average lactation animals belong to the Voli 8369 and Shchepky 4344 families. In some families identified animals that have a lifetime yield of more than 50.0 thousand kg of milk. The influence of the origin of cows on the indices of milk productivity and effectiveness of lifetime use was installed. Between separate parameters of milk production and indicators of the duration and effectiveness of lifetime use of a set of reliable correlation, the magnitude and direction of which are different in animals of different families.

The studies were conducted on the materials of the breeding record of the breeding plant of JSC "Mirne" of Chernivtsi region - the basic farm of the Bukovyna factory type of the Ukrainian red-speckled dairy breed. 360 cows were selected for analysis, based on live weight, yields, fat and protein content of milk, total milk fat and protein content. The intensification of dairy cattle breeding necessitates the systematic evaluation of animals in herds and populations on the basis of economically useful traits. Analysis of the productive qualities of the cows of the different breeding groups showed that, by live weight, milk yield, milk fat and protein content, the two-breed (II breeding group) animals were better than the three-breed (I breeding group). The difference for the first lactation was 11.2; 32.9; 1.5; 1.0 kg respectively. In cows with the second lactation, the pattern remained, the difference was 22.2; 395.8; 15.8; 13.1 kg respectively, and for the third lactation – 31.4; 124.3; 4.8; 4.2 kg. The fat and protein content of milk varied between 3.88–3.89% and 3.33–3.34%, respectively. It should be noted that in cows of both groups there was a decrease in milk milk yield with increasing number of lactations.An evaluation of the productive qualities of the first-born cows of the different lines showed that Marshall's first-borns were better in live weight, milk yield, milk fat and protein, although they were inferior to other lines in terms of fat and protein content. In the firstborn of the Hanover Red line, the estimated values were lower than in animals of other lines, in particular – by live weight by 11.4 kg, milk yield by 1115.2 kg, milk fat by 44.1 kg, milk protein by 37.2 kg (Chif line), by 5.4; 1336.5; 52.7; 45.2 kg (Starbuck line) and 14.7; 1465; 55.1; 48.3 kg (Marshall Line).The effectiveness of breeding for increasing dairy productivity of cows depends on the efficiency of selection and selection of animals, taking into account the phenotypic and genetic correlation between economically beneficial traits. It was found that the highest positive values of correlation coefficients were observed in the cows of the studied groups between milk yield and protein content in the context of all lactations – 1st breeding group (r = 0,12–0,25), 2 nd breeding group (r = 0.19–0.3). In the cows of the first breeding group for the first and second lactations revealed not high but positive correlation of milk yield with live weight (r = 0.33–0.49). In the cows of the second breeding group for the first and second lactation positive correlation with milk fat content was found.The first positive cows of different lines showed the highest positive values of the correlation coefficients between milking and protein content (r = 0.19–0.43). There was also a low positive correlation of milk yield with live weight in the firstborn of all evaluated lines (r = 0.03–0.09), as well as milk fat content in cows of Starbuck and Marshall lines.Conclusions. 1. By live weight, milk yield, milk fat and protein content, two-bovine cows of the Bukovyna factory type of Ukrainian red-speckled dairy breed were better than three-born. The fat and protein content of milk varied between 3.88–3.89% and 3.33–3.34%, respectively. In cows of both groups there was a decrease in milk yield with increasing number of lactations.2. By live weight, milk yield, milk fat and protein content, Marshall Line firsts were better, although they were inferior to other lines in terms of fat and protein content. In the firstborn of the Hanover Red line, the estimates were lower than in other line animals.3. The highest positive values of correlation coefficients were observed between milk yield and protein content in the context of all lactations in the cows of Bukovyna factory type of Ukrainian red-rippled dairy breed. In two breeds of cows for the first and second lactation revealed not high but positive correlation of milk yield with live weight, and in three breeds for the first and second lactation positive correlation of milk yield with fat content.

Studies have shown that the breeding cattle of the Swiss breed of different genotypes used in the selection in Uzbekistan are characterized by high breeding value. The cows obtained from them are distinguished by high milk productivity and fat-milk content, a high milk production coefficient, indicating a pronounced milk type. Cattle of Austrian breeding are characterized by a higher productivity potential. In some cattle cows, the milk yield by 191.3–417.1 kg, the milk yield of 4% milk by 212.6–472.6 kg, the milk yield coefficient by 26.1–45.8 kg exceeds the corresponding indicators of the cows of other cattle. The calves of the cattle nick-named Karan, Koster, Emil and Jordan had milk yield at 1,174.8, 1,219.4; 935.0 and 1,010.4 kg respectively; milk fat yield by 52.9; 55.3; 45.3, and 49.9 kg are higher than the requirements of the republican standard of the Swiss breed. Studies have confirmed that the use of semen from cattle -producers of the Swiss breed in breeding herds, regardless of origin, has a positive effect on the improvement of the main selection characteristics of cows of the Swiss breed of Uzbekistan.

Studies have revealed that despite the selection, the Holstein cows have a high genetic potential of milk production and in all lactations it is good in the specific conditions of the hot climate of Uzbekistan. The milk production level of German cows for the first lactation was 6511.2 kg of milk with a fat content of 3.84%, the Dutch — 6653.0 kg with fat content of 3.95%, and local breed — 6495.2 kg with a fat content of 3.95%. All mature cows retained high milk production, for III lactation and older it was 7112.5 kg and 3.90%, 7266.0 kg and 3.90%, 6847.5 kg and 3.94%, respectively. The yield of Dutch breeding cows was higher for 1 lactation by 141.80–157.8 kg, for III lactation and older by 153.5–418.5 kg, the yield of milk fat by 12.8–6.3 kg, respectively, of indicators peers of German and local selection. The cows of the studied selections combined well with high milk yield and fat content. The level of 4% milk for the studied lactation in all cows was quite high and testified to its good nutritional value. Holstein cows of different breeds are distinguished by a strong dairy type. For I lactation, for every 100 kg of live weight, 1,159.0–1265.5 kg of milk was produced, for III lactation and older - 1200.0–1308.6 kg. It is revealed that milk productivity depends on the level of live weight of cows. The increase in body weight of cows in all groups provides an increase in milk yield, milk fat yield, milk yield of 4% milk. Milk productivity is interrelated with the duration of the service period. In group I, cows with a service period of 91–100 days were more productive, in group II, 81–90 and in group III, up to 80 days. The use of Holstein cows for the production of milk is effective and ensures an increase in its production, the creation of highly productive dairy herds and the production of high-quality maintenance stock.

В статье приведены результаты исследований роста и развития чистопородного кавказского бурого и помесного (кавказская бурая × швицкая) молодняка и воспроизводительной способности телок. Помесные телки при рождении имели живую массу 26,7 кг, а чистопородные — 23,9 кг, то есть преимущество в пользу первых составило 2,8 кг. Различия в показателях живой массы сохранялись и в последующие периоды — в 18-месячном возрасте разница в пользу помесей составляла уже 9,8 кг. Разница в живой массе бычков при рождении составила 2,3 кг, а в 18 мес — 8,3 кг. Помесный молодняк имел преимущество по высотным промерам в возрасте 18 мес на 0,3—1,2 см, а по широтным (ширине, глубине и обхвату груди) — на 0,3—1,9 см. Помесные животные имели более удлиненное туловище на 2,0 см. Продолжительность их стельности в среднем была на 2,1 дня больше (280,4) по сравнению с чистопородными. По показателю крупноплодности бычки, полученные от помесных первотелок, превзошли чистопородных на 1,9%, а телки — на 1,6%. Живая масса первотелок опытной группы была на 16,2 кг больше, чем в контрольной — 385,4 кг против 369,2 кг. За фактическую лактацию помесные первотелки имели удой выше, чем чистопородные, на 96,9 кг, по выходу молочного жира превосходство было на 3,5 кг и белка — на 3,0 кг. The article presents the results of research on the growth and development of purebred Caucasian brown and crossbred (Caucasian brown × Swiss) young animals and the reproductive capacity of heifers. Crossbred heifers at birth had a live weight of 26.7 kg, and purebred — 23.9 kg, that is, the advantage in favor of the first was 2.8 kg. Differences in live weight indicators persisted in subsequent periods — at 18 months of age, the difference in favor of crossbreeds was already 9.8 kg. Differences in the live weight of calves at birth were 2.3 kg, and at 18 months — 8.3 kg. Crossbred youngsters had an advantage in height measurements at the age of 18 months by 0.3—1.2 cm, and in latitudinal measurements (width, depth and chest circumference) — by 0.3—1.9 cm. Crossbred animals had a more elongated body by 2.0 cm. The duration of their pregnancy was on average 2.1 days longer (280.4) compared to purebreds. In terms of the large-fruited bulls obtained from crossbred heifers, purebred exceeded by 1.9% and heifers by 1.6%. The live weight of cows in the experimental group was 16.2 kg more than in the control 385,4 kg vs 369,2 kg. In terms of milk yield for actual lactation, crossbred first — born calves had a higher yield than purebred calves by 96.9 kg, in terms of milk fat yield, the superiority was 3.5 kg and protein — 3.0 kg.

Materials and methods of research. Studies conducted on materials zotehnichnoho primary accounting and breeding breeding farm "Zarya" Kherson region for the period 2010-2012. The object of the research was the daughter of the Ukrainian Red dairy bulls, Holstein (red and white suit), Angler and Red Steppe breeds. Studied cows milk production estimated by yields for the full complete (minimum of 240 days) lactation, content and output of milk fat and protein for 305 days and at higher daily milk yield. Results. The study revealed a significant level of intergroup differentiation and specificity for milk production, reproductive ability, soundings and indices of body structure cows daughters of different bulls. Specifically found that the highest milk yield inherent daughters bull V.Din Et Reda 5661918, which is almost twice prevailed worst analogues daughters Radar 4439 respectively 2484 kg of milk, 93.0 kg of milk fat and milk protein 66.9 kg. The highest daily yield characteristic daughters H.Ch.Herri 5839897, and the lowest - for daughters Radar 4439. The difference in this case was 9.4 kg of milk. Inter-group differentiation on fat and protein in milk is low and under 0.12 and 0.22% by live weight - 14 kg. The difference between  the grounds daughters play different bulls more clearly expressed and 232 days is the age of first calving for the daughters Zenit 1113 and at a rate of 0.201 reproductive capacity for daughters H.Ch.Herri 5839897.

It has been revealed that under the natural and climatic environments of the Western Siberia, when creating favorable conditions for feeding and housing for cows of Holstein and Simmental breeds have sufficiently high milk productivity. It has been found that Holstein first-calf heifers surpassed their Simmental herdmates by 959 kg in milk yield for the first 305 days of lactation under the same conditions of housing and feeding, by 3,1 kg in daily milk yield, by 38,2 kg in milk fat yield, and by 28,3 kg in milk protein yield (P < 0,001). There were no statistically significant differences between animals of Holstein and Simmental breeds in terms of fat and protein content in milk, which amounted to 3,94 and 2,96 % in Holstein breed and 3,97 and 2,98 % in Simmental breed, respectively. Both breeds have shown high milk productivity during the first 3 lactations. Thus, the milk yield of Holstein cows for the first 3 lactation was 6475–9290 kg, Simmental cows it was 5516–7680 kg, fat content was 3,93–3,99 and 3,96–3,97 %, respectively. The protein content in the milk of cows of both breeds did not exceed 3,0 %. High variability has been found in milk yield, yield of milk fat and protein, the coefficient of milk content and duration of lactation, the lowest in the content of protein and fat in milk and live weight. The correlation coefficients between the fat and protein content in milk were generally positive, but did not exceed 0,28. Therefore, breeding in the herd of cows in LLC “Sibirskaya Niva” have to be conducted not only by fat content, but also by protein content in milk.

Dairy cattle breeding is one of the leading livestock sectors whose purpose is to ensure the production of high quality dairy raw materials in volumes meeting the scientifically grounded standards of state food security and expanding the export potential of the agrarian sector. The purpose of our research was to study the status and prospects of dairy cattle breeding in the Kirovograd region. Material and methods of research. The research was carried out on the basis of the electronic database of breeding goals (including 2312 cows), official statistics and estimates of cattle of various breeds that are involved in the production of dairy direction in the breeding farms of the Kirovograd region. The analysis used zootechnical and statistical methods. The calculations were carried out using the software package "STATISTICA-6,1" Results. According to the research (2001–2018), the cattle population in the Kirovograd oblast decreased by a factor of 2.6. Thus, as of January 1, 2018, its number constituted 96.3 thousand heads in all categories of farms, 53.1 thousand of them were cows, the number of which also decreased by 2.4 times. Specific gravity of cattle population of farms remains significant and makes up 72.7%, and 80.6% in the livestock of cows. The largest number of cows of agricultural enterprises declined significantly. Thus, as of January 1, 2018, their number was 10.3 thousand goals, which is 4.7 times less than in the same period of 2001. In the households there is also a tendency for a permanent reduction of cows, the difference is, respectively, 37.0 thousand heads or 46.4% The development of dairy cattle breeding is characterized by two opposite tendencies: reduction of livestock of cows and increase of their productivity. Thus, in agricultural enterprises in 2010, compared to 2000, hopes per cow increased by 2.5 times, in all categories of farms by 1.8 times. In 2017, the increase in dairy costs in agricultural enterprises compared to 2010 amounted to 60.0% in farms of all categories 12.2%. The researches found that in the agricultural enterprises of the oblast as of January 1, 2018 there are 26256 head of cattle, including 10281 cows. The breeding part of the existing cows is 3.013 heads, 29.3% of the total number located in 10 breeding farms. The analysis of the genealogy structure showed that the experimental population of cows belongs to 18 lines and related groups of which the most numerous Chifa 1427381 – 20.4%, Starbuck 352790 – 20.1%, Henev 1629391 – 18.6% , Eleusis 1491007 – 11.2%, Family 267150 – 10.8%. Among the indicated lines, the lowest level of milk productivity was first-born cows. The 1491007, the milk of milk for 305 days of lactation was 4466 ± 99.8 kg, and the milk fat was 168.2 ± 6.5 kg. Analogues l Starbak 352779 was characterized by the highest milk productivity, its level was 5696 + 98.8 kg and 224.9 ± 9.7 kg, respectively. The difference in stomach was 1230 ± 140.4 kg (td = 10.2) and at the release of milk fat 56.7 ± 5.28 kg (td = 10.2) at P < 0.001. However, the latter were markedly less service life (125 against 168 days) and logically higher reproduction rate compared to other lines. An analysis of the intensity of the formation of live weight of young animals has been established for its highest growth in heifers of controlled herds in the period from 9 to 12 months. Thus, in animals of Ukrainian red breed, the growth rate of live weight during this period was 75 kg, Ukrainian red-shrimp 61 kg, Ukrainian black-and-white 73 kg, Holstein 76 kg. Accordingly, during this period, the average daily gain of live weight of young breeds of these breeds was 833 g; 678 g; 811 g, 835 g. The sharp fluctuations of average daily increments during growing periods, first of all, testify to the unequal conditions of growing and feeding young animals than the breed differences. In general, as a result of the analysis of the formation of live weight of heifers, a significant level of phenotypic variability was observed, which confirms sufficient genetic resources and preconditions for selection on the given sign. Therefore, proceeding from the above, in the long run, selection work for breeding improvement of cattle breeding farms of the Kirovograd region should be conducted in accordance with certain promising directions according to groups of breeds. Conclusions. A very important factor in the growth of milk production in the Kirovograd region is high-yield pedigree cattle. The main task on the way of bringing breeding cases in dairy farming to the modern level is the introduction of computer breeding records in breeding farms. This will allow to estimate in the near future bulls-pedigrees, which were used in the past in these farms, to allocate among them complex improvers for precisely the specific conditions and maximally attract them for reproduction. On the other hand, a reliable clogging of poor quality in the genetic sense of sperm production, which leads to negative consequences, will be posed. When establishing the assessment of the breeding value of bulls and developing a single plan of breeding and breeding work in the region, one can proceed to the next step of improving breeding and breeding business, introducing a progressive method of raising the breeding value of animals of large-scale breeding. As a result, the profit from the breeding of highly productive animals, well adapted to specific conditions, will significantly exceed the costs. At the same time, the proposed measures will allow the breeding business to be brought up to the modern world level and stimulate highly productive cattle breeding.
