Цель работы – изучить влияние направленного воспроизводства коров на формирование высокопродуктивных здоровых стад. Методология. Научно-исследовательская работа проведена в базовых хозяйствах Республики Казахстан: СПК «ПЗ Алматы», ИП «Сыдыков», ИП «Каримов», ТОО «Тастобе АгроФуд» Алматинской, ТОО «Какпатас-Кордай» Жамбылской, ТОО «Борте милка» Туркестанской и КХ «Зайтенов» Восточно-Казахстанской областей. Для искусственного осеменения выбирали телок 12-14-месячного возраста живой массой от 360 кг и коров-первотелок голштинской, симментальской, швицкой и черно-пестрой пород. Осеменение проводили ректоцервикальным методом с помощью инструмента Alpha Vision заморожено-оттаянным семенем, разделенным по полу. Результаты. Для ускоренного ремонта стада и увеличения поголовья высокопродуктивных коров в крупных хозяйствах по производству молока используют сексированное семя при первом и втором осеменении первотелок, полученных от высокопродуктивных матерей. Согласно научным данным, эффективность, получаемая от использования данной методики, составляет 65-95 % особей желательного пола. Наиболее высокие результаты плодотворности осеменения сексированным семенем в СПК «ПЗ Алматы», ИП «Каримов» и КХ «Какпатас Кордай» получены в осенне-зимний период и составили от 58,1 до 65,2 %, при индексе осеменения 1,58-1,72. При использовании сексированного семени от первотелок в среднем получено 92 % телок. При сравнительном анализе результатов по всем хозяйствам наиболее высокие показатели плодотворности осеменения отмечены у телок при естественной половой охоте. На фоне гормональной стимуляции половой охоты наблюдается снижение плодотворности осеменения в среднем на 4,72 %. При диспансеризации коров и телок выявлено 202 головы с нарушением воспроизводительных функций, из них вылечено 176 голов (87,13 %), с эндометритом – 81,25 %, с фолликулярной кистой – 86,79 %, с гипофункцией яичников – 91,76 %. Заключение. Научно обосновано и экспериментально доказано влияние направленного воспроизводства коров на формирование высокопродуктивных здоровых стад в базовых хозяйствах Республики Казахстан. Problem and purpose. The purpose of the work was to study the efect of directed reproduction of cows on formation of highly productive healthy herds. Methodology. The research was carried out at the basic farms of the Republic of Kazakhstan: APC “PZ Almaty”, PE “Sydykov”, PE “Karimov”, LLP “Tastobe AgroFood” in Almaty region, LLP “Kakpatas-Kordai” in Zhambyl region, LLP “Borte Milka” in Turkestan region and CF "Zaitenov" in Eastern-Kazakhstan region. For artifcial insemination, a calf of 12-14 months of age was chosen with a living mass of 360 kg and frst-born cows of Holstein, Simmental, Schwitz and black and white breeds. Insemination was performed by recto-cervical method using Alpha Vision tool with frozen-thawed semen divided by sex. Results. For accelerated repair of herd and increase of number of highly productive cows at large dairy farms one uses sexed semen for the frst and the second insemination of fresh cows got from highly productive mothers. According to scientifc data, the efciency obtained from using this technique is 65-95 % of individuals are of the desired sex. The highest results of the fruitfulness of insemination by sexed semen were obtained at APC “PZ Almaty”, PE “Karimov” and LLP “Kakpatas-Kordai” in the autumn-winter period and ranged from 58.1 to 65.2 %, with an insemination index of 1.58-1.72. When using sexed semen from fresh cows, about 92 % of heifers were obtained. With a comparative analysis of the results for all farms, the highest indicators of the fruitfulness of insemination were noted in calves during natural estrus. Against the background of hormonal stimulation of estrus, there was a decrease in the fruitfulness of insemination by an average of 4.72 %. During the medical examination of cows and heifers, 202 heads with impaired reproductive functions were detected, of which 176 heads (87.13 %) were cured, with endometritis - 81.25 %, with follicular cyst - 86.79 %, with ovarian hypofunction - 91.76 %. Conclusion. The infuence of directed reproduction of cows on formation of highly productive healthy herdswas scientifcally and experimentally proved at basic farms of the Republic of Kazakhstan.

Abstract Our work provided for the study of the impact of directed reproduction of cows on the formation of highly productive healthy herds in the basic farms of the Republic of Kazakhstan. For accelerated replacement of herd and increase of number of highly productive cows in large farms for milk production one uses sexed semen at the first and the second insemination of primiparous cows obtained from highly productive mothers. The efficiency obtained from using this technique is 65-95% of individuals of the desired sex. Insemination was carried out by recto-cervical method using a tool AlphaVision frozen-thawed sexed semen divided by sex. The highest results of the fruitfulness of insemination with sexed semen in Agricultural production cooperative “Breeding Plant Almaty”, Individual entrepreneur “Karimov” and Kakpatas Kordai were obtained in the autumn-winter period and ranged from 58.1 to 65.2%, with an insemination index of 1.58-1.72. Economic efficiency when using the technology of artificial insemination of calves with sexed semen amounted to 10,040.2 tenge. When using sexed semen, an average of 92% of calves were obtained from bovine. Less insemination costs, the profit from calf production amounted to 76,109.2 tenge.

Embryo transfer technique is one of the key in accelerated reproduction of cattle. One of the most important stages is the selection of donor cows that are most sensitive to the procedure of hormonal stimulation of ovulation. One of the promising genetic markers of the reproductive status of cattle is currently the gene encoding the luteinizing hormone / choriogonadotropin receptor (LHCGR). One of the SNP in the LHCGR gene of cattle has already been described in the literature as associated with the number of oocytes and the quality of embryos - rs41256848 (c.1401G> T, p.Trp467Cys). The purpose of this work was to estimate the frequencies of genotypes and alleles of this substitution in the population of Black-and-White holsteinized cattle (190 cows). Genotyping was performed by PCR-RFLP method. In the studied population of cattle, the frequency of the G allele associated with higher rates in the total number of oocytes and the number of embryos survived after transplantation, as well as with the least number of unfertilized oocytes, is 63.2%.

The relevance of the work is determined by the fact that the right to life belongs to the basic constitutional human rights, therefore, its observance and protection is the duty of the state. Despite its undeniable importance, today the right to life anywhere in the world is not really ensured in sufficient quantities. The constitutional consolidation of the right to life raises a number of issues related to the concept, nature, legislative and practical implementation of this right. It should be noted that various aspects of the human right to life were considered in the scientific works of G.B. Romanovsky, O.G. Selikhova, T.M. Fomichenko, A.B. Borisova, V.A. Ershov and other Russian authors. The aim of the study is to study and comparative analysis of the legal content of the constitutional norm that defines the right to life, to comprehend and identify possible problems of the implementation of this right. To achieve this goal, this article discusses relevant issues of ensuring the right to life, proclaimed by Article 20 of the Constitution of the Russian Federation and Article 27 of the Constitution of Azerbaijan Republic. The results of a comparative analysis of these constitutional norms and the relevant norms of industry law allow us to determine, that there is no contradiction between Article 20 of the Constitution of the Russian Federation and the norms of the criminal legislation of the Russian Federation, which imply the death penalty as an exceptional measure of punishment, because a moratorium has been imposed on the death penalty in the Russian Federation since April 16, 1997. However, after the abolition of the death penalty in the criminal legislation of the Republic of Azerbaijan in 1998, there was a discrepancy between parts II and III of Article 27 of the Constitution of the Republic of Azerbaijan and the criminal legislation of Azerbaijan Republic that requires the introduction of the necessary changes in the content of the analyzed constitutional norm. The value of the work is determined by the fact that the introduction of appropriate changes will contribute to the further improvement of the Constitution of the Republic of Azerbaijan and the effective implementation of the right to life of everyone.

Subject. To achieve a high level of economic security is a key priority of national development. Employment reveals one of the most important aspects of social development of the individual that is associated with his or her needs satisfaction in the sphere of employment and is boon to economic security. Objectives. The purpose of the study is to show the impact of unemployment on economic security in employment. Methods. I apply such scientific methods as dialectical, historical and logical unity, structural and functional analysis, traditional techniques of economic analysis and synthesis. The methods of multivariate statistical and comparative analysis serve as a methodological basis of the study. To determine the indicator of unemployment, I use the band theory. Results. I underpin the growing role of employment in ensuring economic security. The paper presents a comprehensive assessment of the unemployment status and a comparative analysis of the indicator in the Republic of Mordovia, the Volga Federal District, and the Russian Federation as a whole. I identify trends in the average duration of unemployment, show the distribution of unemployed by level of education and age groups. Conclusions. The average annual unemployment rate in the Republic of Mordovia is lower than in Russia and the Volga Federal District. The findings may be useful for public authorities to substantiate their employment policy at both macro- and meso-levels, for designing programs and strategies for socio-economic development of regions and the social security doctrine, as well as in practical activities of employment services.
