“…On the other hand, the connection between genetic markers and some quantitative traits under different production conditions has not always been considered [28][29][30][31]. The use of phenotypic distances makes it possible to solve this problem and reflects the final result of the genotype-environment interaction [32][33][34][35][36].…”

Background and Aim: The aim of any breeding process is to create a herd based on certain parameters that reflect an ideal animal vision. Targeted herding involves selecting the source of breeding material to be imported from another country. Therefore, there is a problem in selecting a breeding material importer to rapidly form a uterine canopy with the required properties. The purpose of this study was to evaluate a set of predictive milk productivity traits in Holstein cattle across countries. Materials and Methods: This research was based on records of 819,358 recorded animals from 28 countries born after January 1, 2018, from open databases. We used the Euclidean metric to construct dendrograms characterizing the similarity of countries according to the complex milk productivity traits of the daughters of bulls. The Ward method was used to minimize intracluster variance when forming clusters and constructing the corresponding diagrams. Principal component analysis was used to reduce dimensionality and eliminate the effect of multicollinearity. The principal components were selected using the Kaiser–Harris criteria. Results: A ranking of multidimensional complex milk productivity traits in different countries over the past 5 years was performed. A group of leading countries led by the USA was established according to the studied indicators, and the possible reasons for such a division into groups were described. Conclusion: The pressure of purposeful artificial selection prevails in comparison with the pressure of natural selection concerning milk productivity traits in a certain group of countries, which allows specialists to choose suppliers when buying breeding animals and materials. The findings are based solely on data from recorded animals, which may not represent the entire breed population within each country, especially in regions where record-keeping may be inconsistent. It is expected that further studies will include regional data from large enterprises not part of Interbull, with mandatory verification and validation. An important element of such work is seen as the ability to compare the milk productivity of populations from different countries using a different scale, as well as studying the differentiation of countries by other selection traits of dairy. Keywords: breeding material, cattle productivity, dairy productivity traits, Holstein cattle.

Genealogical analysis of European bison population revealed a growing up population despite very low genetic diversity

et al. 2022

In 1919, the European bison population became extinct in the wild. The rescue of the lowland subspecies and the whole species was achieved mainly thanks to individuals from the Białowieża Forest (Polish-Belarusian border). There are currently two breeding lines—the lowland (purebred B. b. Bonasus) founded by 7 individuals and the lowland-Caucasian (hybrids of B. b. Bonasus and B. b. caucasicus) founded by 12 individuals. This genealogical study was conducted on 15,071 individuals recorded in the pedigree book between 1881 and 2020. Its objective was to determine the level of genetic variability and inbreeding almost 100 years after the rescue measures were initiated. The completeness of the pedigree of the reference population was 77% in the fifth generation backwards. A maximum of 23 generations can be traced back in the pedigree. The average inbreeding coefficient and the mean average relatedness of the reference population were very high, about 17% and 16% respectively. No significant amount of new inbreeding was discovered. The reference population has lost 9.11% of the total genetic diversity compared to the population of founders. A male of the Caucasian subspecies Kaukasus was discovered among the ancestors of the lowland lineage reference population. The effective population size calculated based on the increase in inbreeding was 23.93 individuals, based on complete generations equivalent it was 16.1 individuals. Wright’s F-statistics showed very small differences in genotypic frequencies between individuals within the two lineages in the reference population (FIS = 0.10), between individuals and the total population (FIT = 0.04) and low differentiation between lineages (FST = 0.06). The population of the European bison from the Białowieża Forest is generally very uniform but still shows good fitness.

The paper presents data on the assessment of the genetic diversity of five subpopulations of the European bison (Bison bonasus) in Belarus — from the National Park “Belovezhskaya Pushcha”, the National Park “Pripyatsky”, the Osipovichi district (Mogilev area), SEI “Berezinsky Biosphere Reserve” and the Grodno region. In general, the work includes 30 samples of muscle tissue from the collection of Gene bank of wild fauna in SSPA “SPC NAS of Belarus on Bioresources” (Minsk, Belarus). Microsatellites were used as markers to assess genetic diversity, structure, and search for signs of a sharp decline in the size of bison subpopulations in the past. A total of 11 microsatellite markers were used, recommended by the Food and Agriculture Organization of the United Nations for cattle research. The analysis of B. bonasus subpopulation from the NP “Pripyatsky” showed signs of passing through the genetic bottleneck. All studied subpopulations are characterized by a similarly low genetic diversity level in all analyzed indicators (mean number of alleles, allelic diversity, observed and expected heterozygosity). The expected heterozygosity (He) for the three subpopulations from the NP “Belovezhskaya Pushcha”, the NP “Pripyatsky” and from the Osipovichi district ranged from 0.37 to 0.39. For the studied subpopulations, the values of the fixation index were negative. The assessment of the presence of genetic structuring between the subpopulations of bison from the NP “Belovezhskaya Pushcha”, the NP “Pripyatsky” and from the Osipovichi district based on the values of such indexes as Fst and DJost which showed no signs of genetic differentiation, which is also confirmed by principal coordinates analysis (PCoA). The European bison conservation in Belarus has required tremendous efforts in the past. So far, even though the impressively large population size reached in Belarus, B. bonasus status still should not be considered as stable, which is closely linked to aspects of its overall low genetic diversity. Our research confirmed the low genetic variability of Belarusian subpopulations. Therefore, the more extensive research concentrated on identifying genetic diversity is necessary to ensure the beneficial control of gene flow and register a potential correlation of unfavorable gene variants with possible inbreeding depression. These attempts are required to lay the groundwork for the management and protection of the European bison in Belarus.
