“…It is reported that high‐concentrate diets can bring some positive changes in milk yield, milk composition, and milk fatty acid content of dairy cows and dairy goats (Dong et al, 2017; Magan et al, 2021). On the other hand, it is worth noting that high‐concentrate diets also play a role in the growth performance, carcass traits, and meat quality of ruminants (Da et al, 2015; Geng et al, 2020; Majdoub‐Mathlouthi et al, 2013).…”

In the process of modern breeding, high‐concentrate diets are widely used to meet the high energy nutritional requirements of animals but change the form of access to energy and nutrients and the way the organism metabolizes them. Goat psoas major (PM) muscle is a hybrid skeletal muscle whose characteristics are important for the motility and meat quality of goats. However, there are few studies on the effects of high‐concentrate diets on the muscle type and metabolic characteristics of PM in goats. In this study, two treatment groups were set up: high concentrate group (HC) and control group (C). The expression of genes related to muscle type and metabolism of the PM was examined by quantitative PCR. The results showed that high concentrate promoted the conversion of PM fibers from intermediate to slow type at the mRNA level, improved the absorption, transport, and oxidation of fat by PM, and upregulated the expression of calpain system. These changes may be regulated by the involvement of differential expression of MSTN, Myf‐5, and IGF‐2. These results suggest that high concentrate may exert a positive effect on skeletal muscle function, metabolism, and meat quality in goats by affecting the expression of muscle type and metabolism‐related genes.

“…Some SNPs in LEP promoter have been shown to alter plasma LEP level and to influence fertility, energy balance, and milk protein yield of Holstein‐Friesian cattle (Liefers et al, 2005). Geng et al (2020) also reported the association between LEP concentration and several quality traits including marbling of Simmental × Luxi F1 crossbred cattle, although their analysis did not show the effects on meat tenderness and juiciness. To apply these SNPs as a DNA marker, detailed association study with bigger population and expression analysis will be required.…”

The Kumamoto sub-breed of Japanese Brown cattle has unique characteristics, such as great growth rate, and their contribution as future breeding materials is expected.To develop a DNA marker for their breeding, we investigated the effects of Leptin gene, controlling energy homeostasis, on carcass traits of the Kumamoto sub-breed.Sequence comparison identified five single nucleotide polymorphisms (SNPs): four linked synonymous mutations and one nonsynonymous mutation. Statistical analysis revealed that c.239C > T (p.A80V) had significant effects on the traits related with quality grade: beef marbling standard (p = 0.0132), meat brightness (p = 0.0383), and meat firmness (p = 0.0115). The C allele showed favorable effects; these scores of the C/C cattle were significantly higher than those of the C/T cattle. On the other hand, the effect of c.399T > C was observed on meat firmness (p = 0.0172) and beef fat standards (BFS) (p = 0.0129). The C/C cattle showed higher values of these traits than the T/T cattle. Our data suggested that these SNPs in Leptin gene could be used as a DNA marker for breeding of the Kumamoto sub-breed.

“…Leptin is a hormone synthesized and secreted from adipocytes and plays a crucial role in biological functions in cattle. Leptin concentration is positively correlated with meat thickness, marbling score, and intramuscular fat, and is also negatively correlated with cholesterol content [112][113][114]. This indicates supplementation of leptin in meat culture media gives us promising results and improves the meat yield and quality.…”

Cell-culture meat is a novel concept to replace traditional meat produced from animals, and to satisfy rising food demands due to the world population growth. It is still a young field and requires to solve technical issues including cell sources and types, efficient culture for large scale production, taste and texture for customer satisfaction. The current review summarized traditional beef meat production and evaluation methods for customer satisfaction. In particular, serum biomarkers for beef meat evaluation are discussed, which can be applicated for cell-culture meat production.
