The Relationship

Based on the results of the analysis of the relationship between the DGAT1 gene polymorphism and economically valuable traits, it was concluded that animals with the DGAT1KK genotype have the highest milk yield and fat content. When analyzing the relationship of CSN3 gene polymorphism with milk productivity, it was found that higher rates are characteristic of mothers cows with a homozygous CSN3BB genotype. Animals of this group have an advantage, in comparison with the AB and AA genotypes, in milk yield, protein content, mass yield of fat and protein. When studying the data of the relationship between the LGB gene polymorphism and economically valuable traits, it was concluded that animals with the homozygous LGBBB genotype have the highest milk yield, fat, protein content, mass fat and protein yield.

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.

Abstract Russian Ayrshire population of cattle is the second largest in number the world population of animals of this breed. Trimethylaminuria (TMA) is the monogenic disease manifesting in the ‘‘fish off-flavor” of the milk from the sick cows and caused by R238X mutation in the flavin-containing monooxidase 3 gene (FMO3). The aim of our investigation was the analysis of the FMO3 gene polymorphism of Ayrshire cattle breed and its relationship with the milk productivity of the first lactation. The analysis of FMO3 gene polymorphism has been carried out on 352 animals of 5 herds, and associations with the milk productivity due 305 days have been evaluated on 20 healthy cows (RR) and 6 ones-carriers of the mutation (RX). DNA has been extracted by means of the kit “DNA-Extran” (“Syntol”, Russia). The identification of the FMO3 genotypes has been conducted by PCR-RFLP in according to the previously developed method with using TaqI restriction endonuclease. The frequency of animals-carriers of X allele associated with the defect of “fish off-flavor” of milk was in the range 10.21–12.82%. The frequencies of RR, RX and XX genotypes were 76.9, 20.5 and 2.6 %, respectively. The study of relationship between the genotypes on FMO3 gene and productivity traits has shown that the homozygous RR-individuals in comparing to RX-ones had significantly higher levels of the milk yield (+918.6 kg, P ≥ 0.05) and content of the milk protein (+28.8, P ≥ 0.05). Adaptive abilities of RR-cows of Russian selection allowed them to surpass animals of Finnish origin with a similar genotype in milk yield 5,655.6 ± 254.2 against 5,105.0 ± 238.6 kg. The investigations has shown the significant superiority the animals-non carriers of the “fish off-flavor” defect in the milk yield and content of the milk protein. This research was supported by the Ministry of science and higher education АААА-А18-118021590138-1.

. Polymorphisms of genes may be useful as genetic markers for additional selection criteria in dairy cattle breeding for economically advantageous traits. The presented study is dedicated to the influence of gene polymorphism, responsible for milk quality and milk productivity was carried out among Holstein cow-heifers in Integrated Agricultural Production Centre “Stud farm named after Lenin” of Atninsky district of the Republic of Tatarstan. DNA samples were isolated from blood samples of 130 cows for genotyping according to gene of growth hormone (GH) by PCR-RFLP analysis method. The genotypes distribution of the somatotropin gene were as follows: LL – 63.8% (83 animals), LV – 30.0% (39 animals), VV – 6.2% (8 animals), the distribution in frequency of occurrence of alleles L - 0.788 and V - 0.212. When considering the gene polymorphism association with the signs of milk production and the qualitative composition of milk showed prominent results cow-heifers with a LL genotype. The identified relationships indicate the possible genetic improvement of the investigated herds using marker-assisted selection.
