“…As hypothesized, AME significantly decreased ( P < 0.05) the concentrations of MOA and MNA in the liver. Our findings were similar to the results of Liu et al (2019) and Liu and Ao (2021) , who found that supplementation with flavonoids and ethanol extract in the diet of Small-tailed Han sheep significantly decreased the concentrations of MOA and EOA in the Longissimus dorsi muscle and Dorsal subcutaneous , Omental , and Perirenal adipose tissues. In the present study, there was no difference in the concentration of EOA in the livers of lambs between the CON group and the AME group.…”

“…Allium mongolicum Regel contains polysaccharides, flavonoids, polyphenols, and other bioactivators ( Li et al, 2019 ). Our previous studies indicated that A. mongolicum Regel ethanol extract ( AME ) significantly decreased the concentration of BCFAs in the Longissimus dorsi muscle and Dorsal subcutaneous , Omental , and Perirenal adipose tissues of Small-tailed Han sheep ( Liu et al, 2019 ; Liu and Ao, 2021 ). However, the molecular mechanism of this effect has not yet been completely elucidated.…”

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 months old; 33.6 ± 1.2 kg) were randomly divided into two groups and fed for 75 days 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 group (P < 0.05). Furthermore, 461 differentially expressed genes (DEGs) were identified between the CON and AME groups, of which 182 were upregulated and 279 were downregulated in the AME group. The DEGs were enriched in three pathways, namely, glutathione metabolism, ECM-receptor interaction and steroid hormone biosynthesis, as determined by Kyoto Encyclopedia of Genes and Genomes pathway analysis. Finally, CYP2B6, ACOT12, THEM4, ACSF2, LPIN1 and ADCY4 were identified as candidate genes that might be involved in regulating the BCFAs synthesis in the sheep liver.

“…According to many years of experience of local herders, the growth rate of sheep after eating A. mongolicum is accelerated, the incidence of disease is reduced, and the quality and flavor of meat can be significantly improved ( 93 – 95 ). Ao et al have conducted long-term research on the application of A. mongolicum to the mutton industry ( 96 , 97 ). The addition of A. mongolicum polysaccharides and A. mongolicum total flavonoids in the diet proves that A. mongolicum and its extracts can effectively improve the growth performance, antioxidant status, and immune response of lamb, while improving meat quality.…”

The Inner Mongolia Autonomous Region ranks first among the five major pastoral areas in terms of lamb breeding of China. The Inner Mongolia Autonomous Region has a vast territory, with many famous grasslands and thousands of forage plants and multiple local high-quality lamb breeds. After hundreds of years of artificial breeding and improvement, Mongolian sheep have developed many varieties. Different diets, feeding and treatment methods have effects on the production performance, lipid deposition and flavor composition of mutton sheep. Therefore, understanding the relationship among Inner Mongolian lamb, meat quality, and flavor will improve the production of high-quality mutton. The regulation of meat quality and flavor will have a profound impact on the deep processing and income-generating capabilities of mutton. Non-genetic factors affect the quality and flavor of mutton, which are more intuitive than genetic factors. In this review, we cover the contributions made by scientists to explore and improve the quality and flavor of Inner Mongolia lambs through non-genetic means, compare the differences between grazing and drylot-feeding in detail, and summarize some feed additives. We hope that based on our review, we can provide some inspiration to improve the meat quality of Mongolian sheep.

However, it is not clear whether AME affects the synthesis of three BCFAs related to flavor in the rumen of lambs.…”

The objective of this study was to evaluate the effect of Allium mongolicum Regel ethanol extract (AME) on the concentration of three branched-chain fatty acids (BCFAs) related to flavor, fermentation parameters and the bacteria and their correlations in the rumen of lambs. A total of thirty 3-month-old male, Small-tailed Han sheep (33.60 ± 1.23 kg) were randomly distributed into 2 groups as follows: control group (CON) was fed a basal diet and AME group was fed a basal diet supplemented with 2.8 g⋅lamb–1⋅d–1A. mongolicum Regel ethanol extract. AME supplementation decreased (P = 0.022) 4-methyloctanoic acid (MOA) content and tended to lower (P = 0.055) 4-methylnonanoic acid (MNA) content in the rumen. Compared to CON group, the ruminal concentrations of valerate and isovalerate were higher (P = 0.046 and P = 0.024, respectively), and propionate was lower (P = 0.020) in the AME group. At the phylum level, the AME group had a lower abundance of Bacteroidetes (P = 0.014) and a higher abundance of Firmicutes (P = 0.020) than the CON group. At the genus level, the relative abundances of Prevotella (P = 0.001), Christensenellaceae_R-7_group (P = 0.003), Succiniclasticum (P = 0.004), and Selenomonas (P = 0.001) were significantly lower in the AME group than in the CON group, while the relative abundances of Ruminococcus (P < 0.001), Quinella (P = 0.013), and Lachnospiraceae_XPB1014_group (P = 0.001) were significantly higher. The relative abundances of Prevotella (P = 0.029, R = 0.685; P = 0.009, R = 0.770), Christensenellaceae_R-7_group (P = 0.019, R = 0.721; P = 0.029, R = 0.685), and Succiniclasticum (P = 0.002, R = 0.842; P = 0.001, R = 0.879) was positively correlated with MOA and MNA levels, and the relative abundance of Lachnospiraceae_XPB1014_group (P = 0.033, R = −0.673) was negatively correlated with MOA. The relative abundance of Christensenellaceae_R-7_group (P = 0.014, R = −0.744) and Prevotellaceae_UCG-003 (P = 0.023, R = −0.706) correlated negatively with the EOA content. In conclusion, these findings suggest that the AME affected the concentration of BCFAs, fermentation parameters and the rumen bacteria in the rumen of lambs.
