台灣綠蜂膠酒精萃取液對蛋雛雞腸道發炎基因表現量及糞便菌相之影響. (Chinese)

Taiwanese green propolis contains prenylated flavanone, which has antibacterial and antiinflammatory effects. The purpose of this experiment was designed to study the effects of adding Taiwanese green propolis ethanolic extract (TGP) to drinking water on the expression of intestinal inflammation genes and fecal microbiota in laying hen chicks. One-day-old laying hen chicks were divided them into three treatment groups: control group: drinking water; low-dose group: supplementation of300 ppm TGP in drinking water; high-dose group: supplementation of600 ppm TGP in drinking water. Chicks were provided ad libitum access to feed and water for 12 weeks. Results showed that 600 ppm TGP supplementation reduced the inflammation-associated gene expression (inos, tnfa, and ifhy) in the duodenum and ileum, a diversity results showed that TGP supplementation reduced the bacterial diversity in feces, p diversity of principal coordinates analysis confirmed that the bacterial structure between groups was well-separated. TGP supplementation increased the phylum Firmicutes abundance and reduced the genera Escherichia-Shigella, Bacteroidetes, and Veillonella abundance. In conclusion, adding Taiwanese green propolis ethanolic extracts to drinking water can reduce the intestinal inflammatory response and regulate gut microbiota in laying hen chicks.

本試驗旨在探討飲水中添加台灣綠蜂膠酒精萃取液(Taiwanese green propolis ethanolic extract,TGP)對蛋雛雞腸發炎基因表現量及糞便菌相之影響。試驗使用一日齡蛋雞分成三 個處理組, 控制組：一般飲用水、低劑量組：飲水中添加300 ppm TGP及高劑量組：飲水 中添加600 ppm TGP, 专式, 驗期間為期12週。試驗結果顯示, 給予高劑量的TGP能降低十 二指腸及迴腸之發炎相關基因表現量(inos、tnfa及浙y)。菌相a多樣性的結果顯示, 添加 TGP的組別皆使糞便中菌相多樣性降低, p多樣性之主座標分析結果證實各組間之菌相結 構明顯分群。在菌種相對含量上, 給予TGP皆能增加厚壁菌門(Finnicutes)菌種之相對含 量, 在屬的階級上, 給予TGP皆能降低Esc力如c力ja-Shigella ' Bacteroides及VUonella相 對含量。綜合上述, 飲水中添加台灣綠蜂膠酒精萃取液能夠改善蛋雛雞之腸道發炎反應及 調節腸道菌相。.
