1. The aim of this experiment was to investigate the effects of ajwain (Trachyspermum ammi) and dill (Anethum graveolens) essential oils (AEO and DEO, respectively), probiotic (PRO) and mannan-oligosaccharides (MOS) on the growth performance, serum metabolites, meat quality, intestinal morphology and microbial populations of Japanese quail.2. A total of 375 one-day-old Japanese quail were randomly allocated into five treatment groups with five replicates of 15 birds each for a 42 d feeding experiment. The dietary treatments were a basal diet (control) or the same diet supplemented with PRO (0.15 g/kg feed), MOS (2 g/kg feed), AEO (0.25 g/kg feed) or DEO (0.25 g/kg feed).3. AEO, MOS, and PRO supplementation increased weight gain, while diets supplemented with AEO decreased feed intake (FI), and improved feed conversion ratio from d 1 to 21 (P < 0.05). The relative weight of the gizzard was higher in birds supplemented with AEO compared to control group, while the birds fed MOS diet had the longest intestine (P < 0.05). Ceca length was greater in control, MOS and PRO groups (P < 0.05). Both essential oils decreased malondialdehyde (MDA) concentration of breast meat and percentage of cooking loss in quail (P < 0.05). The villus length (VL) was greater in birds fed diet supplemented with MOS, AEO, and DEO (P < 0.05).The population of E.coli decreased in Japanese quail fed MOS, while Lactobacilli spp. count was increased in the MOS group (P < 0.05).4. In conclusion, AEO, MOS, and PRO supplementation exhibited a positive effect on growth performance, while lipid peroxidation of the meat decreased in birds fed AEO and DEO diets. The intestinal morphometric indices increased in quail fed the AEO, MOS, and DEO diets. Supplementation with MOS modulated intestinal microbial populations of the Japanese quail.

植物性饲料添加剂、益生菌和甘露寡糖对日本鹌鹑生产性能、血液代谢产物、肉质、肠道形态和微生物种群的影响。

1. 本实验的目的是研究 ajwain (Trachyspermum ammi) 和莳萝 (Anethum Graveolens) 精油(分别为 AEO 和 DEO)、益生菌 (PRO) 和甘露寡糖 (MOS) 对生长性能的影响,日本鹌鹑血清代谢产物、肉质、肠道形态及微生物种群。 2.将 375 只 1 日龄日本鹌鹑随机分为 5 个处理组,每组 15 只鸡重复 5 次,进行 42 d 的饲养实验。日粮处理是基础日粮(对照)或添加 PRO(0.15 g/kg 饲料)、MOS(2 g/kg 饲料)、AEO(0.25 g/kg 饲料)或 DEO(0.25 g/kg 饲料)的相同日粮).3。添加 AEO、MOS 和 PRO 增加了体重增加,而添加 AEO 的日粮降低了采食量 (FI),并将饲料转化率从第 1 天提高到 21 天(P < 0.05)。与对照组相比,添加 AEO 的鸡的肌囊相对重量更高,而饲喂 MOS 饮食的鸡的肠道最长(P < 0.05)。对照组、MOS 组和 PRO 组盲肠长度更大(P < 0.05)。两种精油都降低了鹌鹑胸肉的丙二醛 (MDA) 浓度和烹饪损失的百分比 (P < 0.05)。饲喂 MOS、AEO 和 DEO 日粮的鸟类绒毛长度 (VL) 更大(P < 0.05)。饲喂 MOS 的日本鹌鹑中大肠杆菌数量减少,而乳酸杆菌 spp。MOS组计数增加(P < 0.05)。4.总之,AEO、MOS 和 PRO 补充剂对生长性能表现出积极影响,而饲喂 AEO 和 DEO 日粮的鸡的肉类脂质过氧化作用降低。饲喂 AEO、MOS 和 DEO 日粮的鹌鹑肠道形态指数增加。补充 MOS 调节的日本鹌鹑肠道微生物群。
