Our previous work has demonstrated that Yupingfeng, a Chinese herb medicine, considered as prebiotic showed beneficial properties in poultry health and disease prevention and regulated intestinal microbiota. The effects of Yupingfeng on fatty acids related to meat flavor and ruminal microbiota are not yet known in Qingyuan black goat. In this study, we supplemented fermented (FYP) and unfermented (UYP) Yupingfeng in different combinations to 90 goats. Compared with the normal control group, FYP and UYP significantly increased the concentration of palmitic acid, octadecanoic acid, and arachidonate acid (related to meat flavor) in the longissimus dorsi muscle (p < .05). In addition, the significant upregulation of peroxisome proliferator-activated receptor gamma (PPARγ) and fatty acid translocase (CD36) was observed in the FYP and UYP groups (p < .05). In addition, Firmicutes and Bacteroidetes were the most abundance in goat rumen. At the genus level, FYP and UYP significantly increased Ruminococcus related to fiber degradation, and Alistipes related to short-chain fatty acids production. In summary, Yupingfeng could improve fatty acids of goat meat, which is probably triggered by the increase of PPARγ and CD36, and microbial activity. Besides, FYP showed more beneficial effects than UYP, with increased flavor fatty acids and beneficial microbes.
我们之前的工作表明，中药玉屏风被认为是一种益生元，在禽类健康和疾病预防方面具有有益特性，并能调节肠道微生物群。然而，在清远黑山羊中，玉屏风对与肉味相关的脂肪酸和瘤胃微生物群的影响尚不清楚。在本研究中，我们以不同组合的方式向 90 只山羊补充发酵（FYP）和未发酵（UYP）的玉屏风。与正常对照组相比，FYP 和 UYP 显著增加了背最长肌中棕榈酸、十八烷酸和花生四烯酸（与肉味有关）的浓度（p<.05）。此外，FYP 和 UYP 组中过氧化物酶体增殖物激活受体γ（PPARγ）和脂肪酸转运蛋白（CD36）的表达显著上调（p<.05）。此外，瘤胃中厚壁菌门和拟杆菌门是最丰富的。在属水平上，FYP 和 UYP 显著增加了与纤维降解相关的瘤胃球菌，以及与短链脂肪酸生成相关的 Alistipes。总之，玉屏风可以改善羊肉的脂肪酸，这可能是通过增加 PPARγ 和 CD36 以及微生物活性来实现的。此外，FYP 比 UYP 显示出更多的有益效果，增加了风味脂肪酸和有益微生物。
