“…Creation of objective methods for evaluation and improvement of quantitative and qualitative indicators of meat productivity in farm animals should be based on a comprehensive analysis of physiological and biochemical parameters of the organism [1]. The great variety of food on the market, together with the increased attention of consumers to the organoleptic properties of products, stimulates the selection of livestock, taking into account the biological and nutritional value of meat [2,3]. The ability to determine lifetime meat quality is severely limited, but is extremely important in livestock production [4].…”

The aim of this study was to investigate the relationship between blood serum biochemical composition and hormonal status of Hereford bulls and beef quality indicators. The object of the study was Hereford bulls (n=9) aged 20-21 months. AST activity was positively correlated with the amount of fat (r=0.70; P<0.05), whereas a similarly strong but inverse relationship (r=-0.87; P<0.05) was found with the moisture content in beef. A significant negative correlation (r=-0.71; P<0.05) was found between thyroxine content and linolenic fatty acid. The most significant correlation of palmitic (r=0.72; P<0.05) and oleic FA synthesis (r=-0.72; P<0.05) was observed with total protein content. Tyrosine, cholesterol and triglyceride levels were negatively correlated with amino acid composition. Moreover, the association of thyroxine with methionine (r=-0.76; P<0.05), triglycerides with arginine (r=-0.82; P<0.05), methionine (r=-0.68; P<0.05) and threonine (r=-0.69; P<0.05) reached significant values in terms of strength. These summary tests objectively describe the peculiarities of synthetic and metabolic processes in the bovine body. A complex approach to predicting the biological value of beef based on correlation with physiological and biochemical indices of blood in young Hereford cattle has been applied to increase the efficiency of selection and breeding work in beef cattle breeding.

“…Each species can inherit the LEP gene (Yupanqui-Lozno et al 2019). LEP gene variants are highly identified to boost goat productivity, impact intramuscular deposition and body weight, and can be employed as a marker-assisted selection (MAS) approach (Sycheva et al 2023). Etawa Cross and Senduro goats come from the same maternal, namely Jamnapari.…”

Abstract. Amrullah MF, Utomo B, Utama S, Lestari TD, Suprayogi TW, Restiadi TI, Belgania RH, Pakpahan S, Khairullah AR, Kurniawan SC, Silaen OSM, Hasib A. 2023. Comparison of genetic diversity of LEP gene between Indonesia domestic goats: Etawa Cross and Senduro Goats. Biodiversitas 24: 6567-6573. The leptin (LEP) gene is a gene that functions to produce the hormone leptin secreted by fat tissue that can increase livestock productivity. This study aimed to identify the profile of the LEP gene between Etawah Cross goats and Senduro goats. Gene profiling includes single nucleotide polymorphisms (SNPs) and phylogeny tree reconstruction. Furthermore, 10 whole blood samples from 5 Etawah Cross goats and 5 Senduro goats were collected from goat farms in Lumajang District, Lumajang Regency, Indonesia. The Research procedure involved collecting blood samples, extracting DNA, amplification using the polymerase chain reaction (PCR) method using specific primers, and nucleotide sequencing method. The edited DNA sequences were aligned with some DNA sequences (n=32) of the Capra hircus group published in Genbank. The results of this study obtained the alignment of the LEP gene sequences of Etawah Cross goats and Senduro goats, including T723A, G729A, G758A, A763T, G774C, T1100C, and G1454A. Based on the LEP gene phylogeny tree, Etawah Cross goats and Senduro goats belong to the same clade and have a close kinship with the Bligon goats. The profile of the LEP gene between Etawah Cross goats and Senduro goats varies so that further studies can be carried out to look for the relationship between SNPs and the productivity traits of the LEP gene.

A review of the scientific literature has shown that the genotype by loci of the Leptin (LEP) gene and linear affiliation to the leading Holstein breed of cows have an impact on milk productivity and the quality of their milk. The purpose of our research was to study the milk productivity and qualitative composition of the milk of Tatarstan-type cows with different genotypes according to the loci of the Leptin gene and linear belonging to the Holstein breed. The research was carried out in the conditions of the agricultural company "Agrofirma Rassvet" of the Kukmorsky district of the Republic of Tatarstan on the livestock of 79 cows of the Tatarstan type. The Tatarstan type is one of the leading dairy cattle breeds bred in the Republic of Tatarstan, and created by crossing the Kholmogorsky, Black and White, and Holstein breeds, while the bloodline was 1/8 Kholmogorsky + 1/16 Black and White + 13/16 Holstein. As a result of a molecular genetic study (PCR-RFLP), the animal population was sorted into groups, taking into account the genotype by the loci of the Leptin gene. The conducted studies have shown that in Tatarstan-type cows after the first lactation, the highest milk yield indicators, the amount of fat and protein in milk were noted in animals with the leptin gene genotypes LEP/CC and LEP/CT in comparison with peers of the LEP/TT genotype. However, in terms of the mass fraction of fat and protein in milk, the trend was reversed. Also, among the cows of the Tatarstan type, according to the first lactation, the highest values of milk productivity indicators (milk yield, amount of milk fat and protein) are in cows with the LEP/CC genotype of linear belonging to the Holstein breed, namely W. Ideal 933122 and R. Sovering 198998.
