中文摘要
本試驗使用油甘枝葉（Phyllanthus emblica leaves and branches, PE）粉末添加於白肉雞飼糧 中，探討其對生長、腸道性狀及抗氧化之影響。試驗採用 320 隻 Ross 308 品種白肉雞 逢機分為四組，分別為基礎飼糧組、添加 0.5、1、2% 之 PE 組。試驗期為 35 日。試 驗結果顯示，在生長表現中，添加 0.5% PE 組較對照組有顯著較高之體增重及飼料效率。 腸道菌相及型態結果顯示，添加 PE 之組別能顯著降地迴腸及盲腸大腸桿菌群及產氣莢 膜梭菌，而添加 0.5% PE 組之空腸絨毛顯著高於其他處理組。此外，添加 PE 之組別能 顯著降低血清中丙二醛（MDA）含量及提高超氧化歧化酶（SOD）、過氧化氫酶（CAT）、 麩胱甘肽過氧化酶（GPx）酵素活性。雞周邊血液單核細胞抗氧化基因調控結果顯示，添 加 PE 之組別顯著降低 NOX1 及 ROMO1 之基因表現，並提高 Nrf2、GST、GCLC、 SOD1 及 HO-1 之基因表現。綜上所述，飼糧中添加 0.5% PE 有助於改善腸道內菌相及 絨毛高度，並提升抗氧化酵素活性及調控抗氧化基因表現，進而提高肉雞之生長性狀。
英文摘要
This study was to investigate the effect of Phyllanthus emblica leaves and branches mixture (PE) on growth performance, intestinal characteristics and oxidative status in broilers. A total of 320 Ross 308 broilers were randomly allocated into four groups: control, basal diet supplemented with 0.5, 1, 2% PE. Each group was fed 35 d. Results showed that 0.5% PE group had significantly better weight gain, improving FCR compared to the control group. Moreover, each PE group significantly reduced Coliform and Clostridium perfringens in ileum and cecum, and 0.5% PE group had significantly higher villus height in jejunum than the other group. Additionally, compared to the control group, each PE group had significantly lower malondialdehyde (MDA) and higher superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activity in serum. In chicken peripheral blood mononuclear cells (cPBMCs), each PE group exhibited significantly higher mRNA levels of antioxidant-regulated genes, such as Nrf2, GST, GCLC, SOD1 and HO-1, and significantly lower NOX1 and ROMO1 gene expression levels. In conclusion, addition of 0.5% PE in basal diet could positively improve growth performance by modulating intestinal characteristics and oxidative status in broilers.
