“…It is known that the indicators of meat productivity of animals cannot be estimated only by conducting a single calculation of the slaughter yield. The morphological composition of the carcass is an important qualitative indicator in assessing meat productivity [9,11,14]. When studying the morphological composition of carcasses (pulp, bones, cartilage and tendons), the absolute and relative content of pulp, bones, cartilage and tendons were taken into account.…”

The scientific and economic experiment was conducted in the conditions of the Michurin collective farm in the Vavozhsky district. The purpose of the research was to conduct a scientific and economic experiment to study the meat productivity of black-and-white cattle of different sex and age groups bred in the conditions of the Michurin collective farm (SHPC), followed by an assessment of the compliance of the beef obtained with the requirements of GOST 34120- 2017. The following experimental groups were formed in the experiment: 1 experimental group (AC) – adult cattle (cows of two or more calves); 2 experimental group (MCP) – young cattle, first-calf cows – young female cattle that calved once; 3 experimental group (MT) - young cattle, heifers aged from 8 months to two years. 4 experimental group (MB) - young animals, bulls aged from 8 months to two years. In the course of scientific and economic experience, it was found that among all sex and age groups of cattle entering for slaughter and primary processing at LLC Uvinsky Meat Processing Plant, only fattening bulls (a group of young animals) fully comply with the requirements of the modern standard GOST 34120-2017 in terms of carcass weight, morphological composition of carcasses.

The single-nucleotide polymorphism (SNP) form of genes is a valuable source of information regarding their suitability for use as specific markers of desirable traits in beef cattle breeding. For several decades, breeding work focused on improving production efficiency through optimizing the feed conversion ratio and improving daily gains and meat quality. Many research teams previously undertook research work on single-nucleotide polymorphism in myostatin (MSTN), thyroglobulin (TG), calpain (CAPN), and calpastatin (CAST) proteins. The literature review focuses on the most frequently addressed issues concerning these genes in beef cattle production and points to a number of relevant studies on the genes’ polymorphic forms. The four genes presented are worth considering during breeding work as a set of genes that can positively influence productivity and production quality.

“…It was found that meat in homozygous CC in CAPN1_316 animals is more tender [29][30][31]. The growth hormone (GH) gene plays an essential role in carbohydrate-fat metabolism [32][33][34][35]. In different breeds of cattle, several SNPs in the GH gene have been described, most of which are located in introns, some in the regulatory sequence, and only one in the fifth exon at position 2141.…”

The current study investigated the impact of growth hormone (GH) and polymorphism of calpain genes (CAPN1) on the changes in live weight and qualitative and quantitative indicators of meat productivity of young Kazakh White-headed cattle. CAPN1 polymorphism is represented by two alleles, C and G, with a frequency of 0.12 and 0.88, three genotypes, CC, CG, GG, with a frequency of 0.06, 0.81, and 0.13, respectively. GH polymorphism -V and L alleles, with a frequency of 0.40 and 0.60, and VV, LV, and LL genotypes with a frequency of 0.31, 0.51, and 0.18, respectively. The CAPN1 C and GH V alleles are preferred for improving the quantity and quality of meat productivity of the Kazakh white-headed cattle. Animals with the CAPN1 CC and GH VV genotypes had a 6.9% higher body weight at 12 months of age (P<0.05) compared to those with the CAPN1 GG and GH LL genotypes. The highest preslaughter, slaughter, and carcass weights were obtained from carcasses of CAPN1 CC and GH VV homozygous bulls. Their superiority over the CAPN1 GG and GH LL genotypes was 19.3; 16.2 and 16.4 kg; 19.8; 19.1 and 16.1 kg, respectively. The difference in favor of these genotypes in terms of the meat ratio by 4.1% and 2.0% was provided by a 9.1% greater meat mass and 1.4% and 2.0% slaughter yield. The protein and fat content in the longissimus muscle of the CC and VV genotypes carcasses was higher by 0.28-2.13%. CAPN1 CC and GH VV animals had a higher concentration of unsaturated fatty acids in their muscle lipids than CAPN1 CG , CAPN1 GG, and GH LV , GH LL genotypes. The best unsaturated to saturated fatty acids ratio and the ratio of arachidonic (C20:4) and linoleic (C18: 2) acids indicate the advantage in beef's dietary properties obtained from beef CAPN1 CC and GH VV animals.
