The aim of the work was to study the traits of dairy productivity of Holstein heifers with different genotypes of the paraoxonase-1 (PON1) gene. The research was conducted in 148 animals of Integrated Agricultural Production Centre “Stud farm named after Lenin” of Atninsky district of the Republic of Tatarstan. Genotyping of cattle was carried out by the PCR-RFLP method at the laboratory of the Department of Agrobiological Research of Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. The results of allele and genotype calling of the PON1 gene showed that the study population is polymorphic and differs in genetic biodiversity. During the analysis of daity productivity, qualitative composition of milk and lactational activity, it was found that cow-heifers with the GG genotype of the PON1 gene were superior to animals with other genotypes in all the test parameters. Thus, it follows that the GG genotype of the PON1 gene has a positive effect on the economic characters of cattle, which can be used in breeding in the future.

The efficiency of selection and breeding work in animal husbandry depends largely on the accuracy of the evaluation of the breeding value of animals. The integration of molecular genetics into applied science made it possible to assess the genetic potential of animal productivity not only on the basis of phenotype data but also directly at the DNA level. The study was conducted on the basis of Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. The object of the study was DNA samples obtained from the blood of Holstein cows belonging to the stud farm “named after Lenin” of Atninsky district of the Republic of Tatarstan. Animal blood was taken from the tail vein using vacutainer tubes with 100mM EDTA. DNA was isolated from the blood in the amount of 100 µl using a set of reagents for DNA extraction from the “Ampliprime DNA-sorb-B” clinical material (NextBio, Russia), according to the method presented by the producer. DNA fragment amplification was performed in T100 Thermal Cycler (Bio-Rad, USA) and on MyCycler programmable Thermal Cycler (Bio-Rad, USA). After amplification, each DNA fragment obtained by us in the study of TG5, CSN3, LGB genes, was subjected to cleavage by a restriction endonuclease. Hydrolysis was conducted at 37°C for 12 hours. The analysis of polymorphism of candidate genes of dairy productivity of leptin, thyroglobulin, kappa casein and beta-lactoglobulin with the use of PCR-RFLP was carried out. The most common were homozygous TG5CC, CSN3AA and heterozygous LEPCT, LGBAB genotypes. The study of the effect of polymorphism of these genes on milk production showed that animal carriers of LEPCT, TG5TT, CSN3AB, LGBBB genotypes have the best indicators of dairy productivity.

The purpose of the research was to study the polymorphism of the paraoxonase-1 gene with the replacement of A with G in the promoter region, as well as to evaluate the growth, milk productivity and reproductive ability of Holstein heifers with different genotypes on this gene. The work was performed in 2018–2019 in the Republic of Tatarstan on 148 first-calf cows. Genotyping was conducted by PCR-RFLP in Bsc4I locus of PON1 gene. The studied population was polymorphic, the genetic balance was not disturbed. The distribution of alleles and genotypes was as follows: A – 0.564 and G – 0.436; AA – 31.8 % (48 animals), GA – 49.3 % (75 animals), GG – 18.9 % (28 animals). Animals with GA genotype of PON1 gene were not significantly better in terms of growth dynamics (kg) in control weighing from 6 to 18 months and of daily gain (g) in 6-18 months period. The cows from the same group were statistically significantly superior to heifers with AA and GG in terms of reproductive ability: fertility index of Dohi (56.2), calving interval (395.7 days), service period (122 days), and were distinguished by the early age of the first successful insemination (17.1 months). It was found that first-calf heifers with the GG genotype were better in milk yield per 305 days of lactation (7339.6 kg), milk fat yield (291.1 kg) and milk protein yield (254.6 kg). The identified associations of PON1 gene polymorphism can be used for the selection of parental pairs for targeted breeding to improve economically useful signs of Holstein cattle

The article is devoted to the history of the formation and development of science in Karakalpakstan. It is stated that in 1931 the Karakalpak Integrated Research Institute was established in Turtkul. In the pre-war period, this institute was reorganized several times, as a result of which difficulties arose in coordinating scientific and research work in Karakalpakstan. In 1947, it was transferred to the Academy of Sciences of Uzbekistan. In 1959, the Karakalpak affiliate of the Academy of Sciences of the Uzbek Soviet Socialist Republic was organized on the basis of the Karakalpak Integrated Research Institute, which made it possible to coordinate and develop fundamental scientific research in the republic. The scientists focused on topical issues of the development of the economy and culture of the republic, in particular, the study of natural resources, material and spiritual culture of the Karakalpak people. The author claims that a new stage in the development of this scientific center begins in 1991, when the Karakalpak affiliate of the Academy of Sciences of the Republic of Uzbekistan receives the status of the Karakalpak branch. The author critically assesses the period of development of science in Karakalpakstan in the 1990s, while claiming that this scientific institution has risen to new stages of its development and certain achievements have been achieved. KEYWORDS. Science; history; scientific expeditions; Karakalpak Scientific Research Institute; reorganization; integrated institute; affiliate, branch; scientific research; department; prospects.

Introduction. The present review article is devoted to written Mongolian collections from repositories in different regions of Russia, which were formed thanks to the selfless work of brilliant Orientalists. At present, there is an urgent need in systematization, analysis, search for information, and distant access to archival records and written sources, which will give researchers more opportunities for distant work with sources. Accordingly, perspectives of using information technologies will fascilitate the coordination and wider cooperation, as well as greater openness in the academic environment, the urgency of which is quite obvious. It is the right moment, too, because, first of all, the data on written sources is still scattered in a variety of publications; secondly, 2018 saw the launch of a grandiose project ”World Heritage of Mongolians”, which is primarily designed to create a uniform inventory of historical-documentary heritage of Mongolian peoples. The project plans include the publication of twenty volumes to present collections of written monuments dispersed in various countries of the world: Russia, Japan, China, the USA, France, Denmark, Hungary, etc. Three volumes will be devoted to Mongolian sources from Russian repositories. The purpose of the present article is to give an overview of the repositories of the documentary heritage of the Mongolian peoples in different regions of Russia. Results. The largest collections of Mongolian written sources are stored in St Petersburg (Scientific Library of St Petersburg University, Institute of Oriental Manuscripts of the Russian Academy of Sciences, State Museum for the History of Religion, National Library of Russia), in Buryatia (Center for Oriental Manuscripts and Xylographs, Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the RAS; V. A. Obruchev Kyakhta Museum for Local Studies), in Tyva (Aldan-Maadyr National Museum of the Republic of Tyva, Scientific Archive of the Tyva Institute for Studies in the Humanities and Applied Socio-Economics), in the Republic of Tatarstan (National Archive of the Republic of Tatarstan), and in Kalmykia (Scientific Archive of the Kalmyk Scientific Center of the Russian Academy of Sciences, National Archive of the Republic of Kalmykia, N.N. Pal´mov Kalmyk Museum of Local Studies); these comprise representative collections, including rare and unique monuments of Mongolian written literature. Some of these collections have been studied to a degree, but there are still many to be introduced into scientific circulation. That is why it is of urgent importance to represent written Mongolian sources, their significant part kept in Russian repositories. Further work on identifying and describing the documentary heritage of the Mongolian peoples will contribute to our knowledge of the field that still needs to be investigated.
