Probiotics and phytogenics in the poultry diet have many positive effects on productivity. The combination of these feed additives has not been studied.
This study was designed for evaluation of synergistic effects of protexin (P) and Gunnera (Gundelia tournefortii L.) extract (GX) on growth, biochemical, hematological and antioxidant status of broiler chickens.
Totally, 300 chicks were divided into 4 groups that fed the basal diet, diet containing P, GX, and GX plus P (GX-P) in all over the growing period. At 42 days of age, blood samples were collected from all chickens. The concentration of aspartate transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), triglyceride (TG), cholesterol (CHL), low-density lipoprotein (LDL), high-density lipoprotein (HDL), superoxide dismutase (SOD), total antioxidant capacity (TAC), Glutathione peroxidase (GPx), haematological parameters, and humeral antibody against Newcastle disease vaccine was measured.
The Results showed that the feed conversion ratio in chickens fed GX-P was significantly lower than others. Also, in chickens fed GX or GX-P, the TG and CHL concentration was significantly lower and GPx and TAC concentration was significantly higher than others, while chickens that received P or GX-P showed higher haemoglobin and TP concentration. The antibody response was significantly higher in chickens fed P. The ALT, AST, ALP, and SOD concentration did not show any significant difference in all chickens.
Continuous utilization of P along with GX in broiler diets can induce synergist effect on feed efficacy and antioxidant status, lowering lipid profiles with no effect on liver function in chickens.
在禽类日粮中添加益生菌和植物提取物对提高生产性能有许多积极影响。但尚未研究这些饲料添加剂的组合。
本研究旨在评估 Protexin（P）和 Gundelia tournefortii L.提取物（GX）对肉鸡生长、生化、血液学和抗氧化状态的协同作用。
将 300 只小鸡分为 4 组，分别在整个生长期内饲喂基础日粮、含 P 的日粮、含 GX 的日粮和含 GX 和 P 的日粮（GX-P）。在 42 日龄时，从所有鸡中采集血液样本。测量天门冬氨酸转移酶（AST）、丙氨酸氨基转移酶（ALT）、碱性磷酸酶（ALP）、甘油三酯（TG）、胆固醇（CHL）、低密度脂蛋白（LDL）、高密度脂蛋白（HDL）、超氧化物歧化酶（SOD）、总抗氧化能力（TAC）、谷胱甘肽过氧化物酶（GPx）、血液学参数和对新城疫疫苗的血臂抗体。
结果表明，饲喂 GX-P 的鸡的饲料转化率明显低于其他组。此外，饲喂 GX 或 GX-P 的鸡的 TG 和 CHL 浓度明显较低，而 GPx 和 TAC 浓度明显较高，而饲喂 P 或 GX-P 的鸡的血红蛋白和总蛋白浓度较高。饲喂 P 的鸡的抗体反应明显更高。所有鸡的 ALT、AST、ALP 和 SOD 浓度均无明显差异。
在肉鸡日粮中连续使用 P 与 GX 可以协同提高饲料效率和抗氧化状态，降低脂质谱，而对鸡的肝功能没有影响。
