Transcriptome analysis reveals candidate genes of the synthesis of branched-chain fatty acids related to mutton flavor in the lamb liver using Allium mongolicum Regel extract.

ABSTRACT: The objective of this study was to identify candidate genes via which Allium mongolicum Regel ethanol extract (AME) affects the synthesis of branched-chain fatty acids (BCFAs) related to mutton flavor by transcriptome analysis in the lamb liver. Thirty male Small-tailed Han sheep (3 mo old; 33.6 ± 1.2 kg) were randomly divided into two groups and fed for 75 d with a basal diet containing no AME (CON, control group) or 2.8 g·lamb-1·d-1 AME (AME group). Twelve sheep, CON (n = 6) and AME (n = 6), were selected for slaughter at the end of the trial period, and liver samples were subsequently collected. There was no difference in 4-ethyloctanoic acid content among treatments. The 4-methyloctanoic acid and 4-methylnonanoic acid levels were significantly lower in the AME group than in the CON gro
