Effects of tributyrin on mtDNA and mRNA levels of mitochondrial function-related genes of weaned pigs. Values are means and SD represented by vertical bars. *Differences were considered significant at P < 0.05. mtDNA: mitochondrial DNA; PGC-1α: peroxisomal proliferator-activated receptor-γ coactivator-1α; TFAM: mitochondrial transcription factor A; NRF-1: nuclear respiratory factor-1
