The milk productivity increasing in combined with animal longevity ensures the achievement of optimal economic indicators (profitability, payback period of investment projects), reduction of the negative impact of inflation and other macroeconomic factors on the financial results of organizations specializing in milk production. At the example of one of the breeding farms of the Republic of Karelia, a analysis of productivity indicators of dairy cows was conducted (441 species). Processing of the experimental materials was conducted by using methods of cluster, factor and discriminating analysis, which allowed not only for not grouping the numerous population according to homogeneity of manifestations of zootechnical indicators, but also to establish the structure of connections between the researched variables (life longevity, milk production, contents of fat, live weight, and age of the first calving, alleles, and the reasons for disposal). The step-by-step discriminative analysis confirmed by 97,73 % the reliability of dividing the animals into three groups (clusters). Among the principal discriminators dividing the cows reliably were: life expectancy, productivity, live weight and age of the first calving. The use of factor analysis established the direct unidirectional connection between the allele of EAB-system and the reason for the animal withdrawal.

Целью исследований являлось определение эффективности производства молока при внедрении местных нетрадиционных кормовых добавок в кормлении первотелок красной степной породы. Научно-производственных опыт был проведен в условиях сельхозкооператива Республики Саха (Якутия). По методу аналогов были сформированы опытная и контрольная группы. В период проведения производственного опыта первотелки контрольной группы потребляли основной рацион. Первотелки опытной группы дополнительно к основному рациону получали на 1 голову цеолит в дозе 1 г на 1 кг живой массы, 300 г сапропеля и 60 г Кемпендяйской соли. При включении местных нетрадиционных кормовых добавок в рацион первотелок отмечено улучшение молочной продуктивности. В опытной группе на производство 1 кг молока было затрачено 1,48 ЭКЕ против 1,67 в контрольной группе. При сравнении среднесуточного удоя отмечена разница в контрольной группе 7,73 кг, в опытной — 8,58 кг молока, при этом валовое производство молока составило 127185 и 141215 кг, соответственно. Включение местных нетрадиционных кормовых добавок в состав рациона первотелок способствовало повышению молочной продуктивности на 10,09%. При изучении экономической эффективности внедрения местных нетрадиционных кормовых добавок в кормлении первотелок было установлено, что в опытной группе животных было дополнительно получено 653,5 тыс. руб. при дополнительных затратах 19,8 тыс. руб. Таким образом, использование местных нетрадиционных кормовых добавок в кормлении первотелок способствует повышению молочной продуктивности. The aim of the research was to determine the efficiency of milk production when introducing local non-traditional feed additives in the feeding of heifers of the red steppe breed. Scientific experience was carried out in the conditions of the Agricultural Production Cooperative "Crosses" of the Suntarsky district of the Republic of Sakha (Yakutia). To conduct the experiment, the experimental and control groups were formed by the method of analogues. During the production experience, the control group first calves consumed the main diet. An experimental group of heifers in addition to the main diet received zeolite per 1 head in a dose of 1 g per 1 kg of live weight, 300 g of sapropel and 60 g of Kempendiai salt. When local non-traditional feed additives were included in the feeding of heifers, there was an improvement in milk productivity, so in the experimental group of animals 1.48 energy feed units were spent on the production of 1 kg of milk compared to 1.67 in the control group. When comparing the average daily milk yield, the difference in the control group was 7.73 kg, and in the experimental group 8.58 kg of milk, while the gross milk production was 127185 and 141215 kg, respectively. The inclusion of local non-traditional feed additives in the diet of heifers contributed to an increase in milk productivity by 10.09%. When studying the economic efficiency of introducing local non-traditional feed additives in the feeding of heifers, it was found that 653.5 thousand rubles were received in the experimental group of animals. at additional costs 19.8 thousand rubles. Thus, the use of local non-traditional feed additives in feeding heifers contributes to an increase in milk productivity.

По состоянию на 27 февраля 2020 года во всех категориях хозяйств Республики Саха (Якутия) численность поголовья крупного рогатого скота составила 190039 голов, из них  76075 коров. На примере скотоводства Центральной агропромышленной зоны республики рассмотрены состояние, проблемы и возможности повышения молочной продуктивности коров самой многочисленной из разводимых пород республики — симментальской (более 75% в структуре поголовья). Установлено уменьшение ее поголовья, в том числе коров.  Снижение численности скота и низкий среднегодовой удой отрицательно отразились на валовом производстве молока в республике. Анализ рационов кормления коров в стойловый и пастбищный периоды 2016—2017 годов показал несоответствие рационов рекомендуемым нормам кормления, прежде всего, отмечен дефицит протеина и энергии. Несбалансированность рационов способствовала снижению продуктивности скота в 2017 году: удой на 1 фуражную корову уменьшился на 153,8 кг и выход телят — на 14%. Кормление симментальских коров согласно рекомендуемым нормам по обменной энергии и питательным веществам обеспечит реализацию потенциала молочной продуктивности и повысит выход телят. As of February 27, 2020, in all categories of farms in the Republic of Sakha (Yakutia), the number of cattle was 190,039 heads, of which 76,075 were cows. In the example of cattle breeding in the Central agro-industrial zone of the republic, the state, problems and possibilities of increasing the milk productivity of cows of the most numerous of the breeding breeds of the republic — Simmental (more than 75% in the structure of livestock) are considered. A decrease in her livestock, including cows, has been established. The decline in the number of livestock and the low average annual milk yield had a negative impact on the gross milk production in the republic. Analysis of the rations for feeding cows in the stall and pasture periods of 2016–2017 showed that the rations did not correspond to the recommended feeding norms, primarily, there was a deficiency of protein and energy. The imbalance in diets contributed to a decrease in livestock productivity in 2017: milk yield per forage cow decreased by 153.8 kg and calf yield — by 14%. Feeding Simmental cows according to the recommended metabolic energy and nutrient levels will ensure the potential of milk production is realized and the calf yield will be increased.

Aim: This study aimed to determine the effect of thyroglobulin (TG5) gene polymorphism on milk and meat productivity in the various cattle breeds currently bred in the Republic of Bashkortostan. Materials and Methods: The test was performed on dairy cattle of Black-and-White, Bestuzhev, and Simmental breeds, and meat cattle of Hereford and limousine breeds. The purpose of the test was to search for associations between the polymorphic alleles of the thyroglobulin (TG5) gene and economically useful traits. Results: All studied breeds showed a frequency predominance of the TG5C allele (from 0.56 to 0.71). A clear trend of an effect of the genotypes of the TG5 gene on milk-productivity indicators was revealed; cows with the TG5TT genotype have the highest milk yield and fat content in milk. The milk of cows of Bestuzhev and Simmental breeds that possessed this genotype was also characterized by higher protein content. Conclusion: We identified an effect of the polymorphism of the TG5 gene in the Hereford and limousine breeds on fat metabolism intensity indicators, such as fat output and fat content, in the longissimus muscle and in the general sample of ground beef.

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.

The paper presents the results of studies of milk productivity of black-and-white cows depending on the age of the first insemination and live weight at the first calving in the conditions of the Irkutsk region. The dynamics of heifer rearing by year, milk productivity of cows in the 1st and 3rd lactations depending on the intensity of their development has been studied. The experiment was conducted on farm materials from the Irkutsk Region using generally accepted zootechnical, analytical, variation and statistical research methods from 2016 to 2020. Live weight of heifers at all ages met the requirements of the elite and elite-record classes. Analysis of the data showed that the growth rate of the animals increased during 5 years (6.0%, 6.8, 2.3 and 4.8% respectively with a significant difference p ≥ 0.90). With the increased intensity of heifer rearing, an increase in milk yield over 305 days of the first lactation was observed. The highest milk production was noted in the 1st (5309-5476 kg) and 3rd (5418-5817 kg) lactations in cows with the first fruitful insemination at 13-14 months. The lowest 1st and 3rd lactation yields are obtained from cows inseminated at 20 months of age or older. Higher milk production in the first and third lactations was obtained from cows with a live weight at first calving of 541-550 kg, 551 kg and higher (5197-5164, 5436-5545 kg respectively). Less milk production was obtained from cows with a live weight at first calving of up to 500 kg (4567-5122, 4943-5009 kg). The results obtained make it possible to reveal the influence of the intensity of rearing heifers on the productive qualities of cows.

One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

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).
