| 中文摘要 | 本研究為以餘甘子葉枝混合物（PE）對肉雞生長性能、氧化狀態和腸道特性的影響，以及餘甘子葉枝混合物（PEE）體外抗氧化潛力。 體外評估的結果是，PEE的總酚化合物含量為95.5±2.75mg沒食子酸當量/g乾重(DW)，總黃酮含量為3.04±0.06mg槲皮素當量/gDW。 PEE 透過多種機製表現出顯著的抗氧化活性，包括亞鐵螯合、還原力、清除1, 1-二苯基-2-三硝基苯肼(DPPH) 自由基、抑制脂質體過氧化和trolox 等效抗氧化能力(TEAC)。 共有 320 隻 Ross 308 肉雞隨機分為四組：對照組，基礎日糧添加 0.5%、1%、2% PE。 每組均飼餵35 d。 結果表明，與對照組相比，飼餵0.5% PE的組別增重明顯更好，飼料轉換率（FCR）也有提高。 此外，每個PE組顯著減少迴腸和盲腸中的大腸桿菌群和產氣莢膜梭菌。 此外，0.5%濃度的PE組空腸絨毛高度顯著高於另一組。 此外與對照組相比，各PE組血清中丙二醛（MDA）顯著降低，超氧化物歧化酶（SOD）、過氧化氫酶（CAT）及穀胱甘肽過氧化物酶（ GPx）活性顯著上升。 在雞的周邊血單核細胞（PBMC）中，每個PE組的抗氧化調節基因的mRNA水平顯著升高，包括Nrf2、GST、GCLC、SOD1和HO-1。 相較之下，NOX1和ROMO1基因的表達量顯著降低。 總之，在基礎飼糧中添加 0.5% PE 可以透過調節腸道特性和氧化狀態，對肉雞的生長表現產生正面影響。 |
| 英文摘要 | This study investigated the effect of Phyllanthus emblica leaves and branches mixture (PE) on growth performance, oxidative status and intestinal characteristics in broilers, as well as the in vitro antioxidant potential of PE extract (PEE). As the result of in vitro evaluation, the PEE had a total phenolic compound content of 95.5 ± 2.75 mg of Gallic acid equivalent/g dry weight (DW), and a total flavonoid content of 3.04 ± 0.06 mg of quercetin equivalent/g DW. The PEE exhibited significant antioxidant activity through various mechanisms, including chelation of ferrous iron, reducing power, scavenging 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals, inhibition of liposome peroxidation and trolox equivalent antioxidant capacity (TEAC). 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 for 35 d. The results showed that the group fed with 0.5% PE had significantly better weight gain, and improved feed conversion ratio (FCR) compared to the control group. Moreover, each PE group significantly reduced coliform and Clostridium perfringens in the ileum and caecum. Additionally, PE group with 0.5% concentration had significantly higher villus height in the jejunum compared to the other group. Furthermore, compared to the control group, each PE group had significantly lower levels of malondialdehyde (MDA) and higher levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activity in the serum. In the peripheral blood mononuclear cells (PBMCs) of chickens, each PE group showed significantly higher mRNA levels of antioxidant-regulated genes, including Nrf2, GST, GCLC, SOD1 and HO-1. In contrast, the expression levels of NOX1 and ROMO1 genes were significantly lower. In conclusion, the inclusion of 0.5% PE in the basal diet could have a positive impact on the growth performance of broilers by modulating intestinal characteristics and oxidative status. |
