This study was carried out to explore the influence of black and red pepper oils (BRPO) as a natural antibacterial agent on growth, carcass, liver and kidney functions, lipid profile, immunity and antioxidant indices of growing quails. A total of 225 Japanese quails (1‐week‐old) were haphazardly divided into 5 groups, each group consists of 45 unsexed birds with 5 replications (9 birds each). The first group was fed basal diet (control), and the 2nd, 3rd, 4th and 5th groups fed rations containing BRPO (0.4, 0.8, 1.2 and 1.6 g/kg diet respectively). During 1–3 weeks of age, body weight gain (BWG) and feed conversion ratio (FCR) were improved with dietary BRPO. During 3–5 and 1–5 weeks of age, BWG was quadratically increased with BRPO supplementation. Also, a quadratic improvement in FCR was observed with BRPO during the overall period. There were no statistical differences in all carcass parameters due to BRPO treatment. Feeding quails on rations enriched with BRPO was linearly influenced liver functions. The highest BRPO levels (1.2 and 1.6 g/kg diet) minimized plasma content of total cholesterol (TC) and triglyceride (TG) respectively. Malondialdehyde (MDA) was reduced in quails fed diets supplemented with BRPO. In apart from the highest level of BRPO, complement 3 (C3) was increased with increasing BRPO level. Birds fed diets enriched with BRPO exhibited lower colonization of TBC, lactobacilli, coliform, Salmonella and E. coli than those in the control group. It could be concluded that dietary BRPO can positively affect quail growth, liver and kidney functions, antioxidant and immunity parameters, lipid profile and lipid peroxidation as well as pathogenic bacteria.

膳食冷榨红黑胡椒油混合物可增强鹌鹑的生长、胴体、血液化学、抗氧化剂、免疫力和盲肠病原体。

本研究旨在探讨黑胡椒和红辣椒油 (BRPO) 作为天然抗菌剂对生长鹌鹑的生长、胴体、肝肾功能、血脂、免疫和抗氧化指标的影响。将总共​​ 225 只日本鹌鹑(1 周龄)随意分为 5 组,每组由 45 只未进行性交的鸟组成,重复 5 次(每组 9 只鸟)。第一组饲喂基础日粮(对照),第二、三、四和五组饲喂含有 BRPO 的日粮(分别为 0.4、0.8、1.2 和 1.6 g/kg 日粮)。在 1-3 周龄期间,日粮 BRPO 可改善体重增加 (BWG) 和饲料转化率 (FCR)。在 3-5 周龄和 1-5 周龄期间,BWG 随 BRPO 补充剂呈二次方增加。此外,在整个时期内,使用 BRPO 观察到 FCR 的二次改进。由于 BRPO 处理,所有胴体参数均无统计学差异。用富含 BRPO 的口粮喂养鹌鹑会线性影响肝功能。最高的 BRPO 水平(1.2 和 1.6 g/kg 饮食)分别使总胆固醇 (TC) 和甘油三酯 (TG) 的血浆含量降至最低。鹌鹑饲喂添加 BRPO 的日粮中丙二醛 (MDA) 减少。除了最高水平的 BRPO 外,补体 3 (C3) 也随着 BRPO 水平的增加而增加。饲喂富含 BRPO 的日粮的家禽表现出较低的 TBC 定植,鹌鹑饲喂添加 BRPO 的日粮中丙二醛 (MDA) 减少。除了最高水平的 BRPO 外,补体 3 (C3) 也随着 BRPO 水平的增加而增加。饲喂富含 BRPO 的日粮的家禽表现出较低的 TBC 定植,鹌鹑饲喂添加 BRPO 的日粮中丙二醛 (MDA) 减少。除了最高水平的 BRPO 外,补体 3 (C3) 也随着 BRPO 水平的增加而增加。饲喂富含 BRPO 的日粮的家禽表现出较低的 TBC 定植,乳酸杆菌、大肠菌群、沙门氏菌大肠杆菌高于对照组。可以得出结论,日粮 BRPO 可以对鹌鹑生长、肝肾功能、抗氧化和免疫参数、脂质谱和脂质过氧化以及致病菌产生积极影响。
