“…Myristic acid, palmitic acid, stearic acid and pentadecanoic acid were the major SFA in the beef of cattle under the study. Similarly, a study reported the dominant SFAs in cattle fat as myristic (C14:0), palmitic (C16:0), and stearic (C18:0) acids [39]. The age and breeds of cattle had a significant influence (P < 0.05) on fatty acid profiles in the present study.…”

This study was conducted to determine proximate composition and profile of fatty acid of beef from Arsi, Borana and Harar Cattle breeds in Ethiopia. A total of 39 bulls with three age categories were used for the study. The bulls were purchased from mixed crop livestock system (Arsi and Harar cattle breeds) and Ranch (Borana cattle breed). Complete randomized design was used for the study. Longissimus dorsi muscle was used to evaluate proximate composition and profile of fatty acid. The result of the study indicated that mean of percentage of dry matter, ash, crude fat and crude protein were ranging 22. 43 -24.26, 0.32 -1.28, 4.32 -7.88, 17.21 -22.76, respectively. At age younger than 3 years, Harar bulls contain more crude fat compared to Arsi bulls while the vice versa was true for crude protein. The concentration of polyunsaturated fatty acid (PUFA) was higher than saturated fatty acid (SFA) in the three breeds studied across all age categories. However, significantly higher (P < 0.01) PUFA and lowest (P < 0.05) SFA found in Harar breed whereas the opposite hold true for Arsi bulls. Ratio of n-6: n-3 in the muscle of bulls under the study was ranged from 2.10 to 2.57. Concentration of PUFA and MUF in muscle of the three breeds were significantly affected (P < 0.05) by age. From the study it was concluded that Arsi, Boran and Harar bulls under the three age categories contained more than 3% minimum crude fat that is required to insure palatability of the beef. The higher concentration of PUFA over SFA in all breeds across age categories indicated that the meat from these cattle breeds has less risk hazard to human health.

“…The breast muscle of chicken is highly favored due to its rich content of fatty acids, which directly influence the taste, flavor, tenderness, and nutritional value of chicken meat [1]. However, the composition and content of these fatty acids are regulated by various factors such as genetics and nutrition [2][3][4][5]. Therefore, it is of great significance to understand the molecular regulatory mechanisms behind the fatty acid composition and content in chicken breast muscle.…”

Background The composition and content of fatty acids in the breast muscle are important factors influencing meat quality. In this study, we investigated the fatty acid composition and content in the breast muscle of Gushi chickens at different developmental stages (14 weeks, 22 weeks, and 30 weeks). Additionally, we utilized transcriptomic data from the same tissue and employed WGCNA and module identification methods to identify key genes associated with the fatty acid composition in Gushi chicken breast muscle and elucidate their regulatory networks. Results Among them, six modules (blue, brown, green, light yellow, purple, and red modules) showed significant correlations with fatty acid content and metabolic characteristics. Enrichment analysis revealed that these modules were involved in multiple signaling pathways related to fatty acid metabolism, including fatty acid metabolism, PPAR signaling pathway, and fatty acid biosynthesis. Through analysis of key genes, we identified 136 genes significantly associated with fatty acid phenotypic traits. Protein–protein interaction network analysis revealed that nine of these genes were closely related to fatty acid metabolism. Additionally, through correlation analysis of transcriptome data, we identified 51 key ceRNA regulatory networks, including six central genes, 7 miRNAs, and 28 lncRNAs. Conclusion This study successfully identified key genes closely associated with the fatty acid composition in Gushi chicken breast muscle, as well as their post-transcriptional regulatory networks. These findings provide new insights into the molecular regulatory mechanisms underlying the flavor characteristics of chicken meat and the composition of fatty acids in the breast muscle.

“…In addition, the amount of fatty acids in beef is crucial for the reason that it affects the lusciousness of the beef and human well‐being. But the effects of harmful fatty acids on human health have received less attention in some regions of the world (de Lemos et al., 2017). In this regard, several studies have been done in various parts of the world to determine the role of transcription factors in beef cattle adipogenesis and lipogenesis.…”

In the past few decades, genomic selection and other refined strategies have been used to increase the growth rate and lean meat production of beef cattle. Nevertheless, the fast growth rates of cattle breeds are often accompanied by a reduction in intramuscular fat (IMF) deposition, impairing meat quality. Transcription factors play vital roles in regulating adipogenesis and lipogenesis in beef cattle. Meanwhile, understanding the role of transcription factors in regulating adipogenesis and lipogenesis in beef cattle has gained significant attention to increase IMF deposition and meat quality. Therefore, the aim of this paper was to provide a comprehensive summary and valuable insight into the complex role of transcription factors in adipogenesis and lipogenesis in beef cattle. This review summarizes the contemporary studies in transcription factors in adipogenesis and lipogenesis, genome‐wide analysis of transcription factors, epigenetic regulation of transcription factors, nutritional regulation of transcription factors, metabolic signalling pathways, functional genomics methods, transcriptomic profiling of adipose tissues, transcription factors and meat quality and comparative genomics with other livestock species. In conclusion, transcription factors play a crucial role in promoting adipocyte development and fatty acid biosynthesis in beef cattle. They control adipose tissue formation and metabolism, thereby improving meat quality and maintaining metabolic balance. Understanding the processes by which these transcription factors regulate adipose tissue deposition and lipid metabolism will simplify the development of marbling or IMF composition in beef cattle.
