Results indicated significant differences on cellular and molecular characteristics between male and female cells, including energy metabolic trait, mitochondrial DNA (mtDNA) replication and transcription, and mRNA expressions of mitochondrial biogenesis genes and mitoprotease genes. Referring to sex, males exhibited significantly higher oxygen consumption rate productions, levels of reactive oxygen species (ROS) and mtDNA copy numbers than those with females in muscle and ear fibroblasts. And the expressions of mtDNA, mitochondrial biogenesis genes (POLG, PPARGC1A, TFAM and TWNK) and XPNPEP3 were higher in males than females in ear fibroblasts derived from 1-year-old adult pigs (EFA cells). While, the cell proliferation and expressions of genes related to ROS metabolism were not influenced by sex.

Jeju Black cattle exhibited significantly higher ruminal diversity (p < 0.001), whereas Holstein and Jersey cows had more diverse fecal microbiomes. Prevotella, Ruminococcus and Succinivibrio dominated the rumen of commercial breeds, while Methanobrevibacter and Desulfovibrio were enriched in Jeju Black cattle. Amino acid prototrophs were abundant in Holstein and Jersey feces, while sulfur-metabolizing microbial phenotypes predominated in the Jeju Black rumen, with implications for nitrogen metabolism and methane production. Microbial network analysis revealed Mogibacterium as a high-centrality genus in Holstein and Jersey cows, and Anaerovibrio in Jersey cows, potentially linked to propionate production. Jeju Black cattle displayed distinct microbial interactions involving sulphur-reducing and methanogenic bacteria. These results might be showing breed-related microbiome variability, potentially influencing feed efficiency, fermentation, and emissions.
