This study aimed to investigate the effects of dietary dried onion and dried cinnamon supplementation on laying performance, egg quality, serum lipid profile, and immune responses of Japanese quails. A total of 120 laying quails aged 12 weeks were randomly allocated into five groups (24 birds each). Each treatment was replicated 4 times with 6 quails in a completely randomized design. Dietary treatments were as follows: control (basal diet only, without any supplementation); tylosin (basal diet + 100 mg tylosin/kg diet); onion (basal diet + 800 mg dried onion/kg diet); cinnamon (basal diet + 800 mg dried cinnamon/kg diet); and onion + cinnamon (basal diet + mixture of 400 mg each of dried onion and dried cinnamon/kg diet). Cinnamon supplementation improved laying rate, egg numbers, egg mass, and feed conversion ratio of quails compared to the control treatment, followed by tylosin supplementation. Egg shell percentage was higher (P < 0.05) in quails that consumed the onion + cinnamon mixture than those fed only the cinnamon supplemented diet. Serum total lipid content, egg yolk lipids and egg yolk cholesterol were lower (P < 0.05) in birds fed with the supplemented diets than that of the control group. On the other hand, dietary supplements did not affect levels of triglycerides and high-density lipoprotein levels. The dietary supplementation with onion and/or cinnamon reduced serum malondialdehyde levels compared to control treatment. The foot web index was higher (P < 0.05) in the onion treatment than in the other experimental groups. The dried cinnamon and the mixture of dried onion + dried cinnamon treatments showed higher (P < 0.05) immunoglobulin M (IgM) levels than the control treatment. In conclusion, dietary supplementation with natural plant materials such as dried onion and cinnamon can be used to improve the laying Japanese quail performance, egg quality, and immunity.
本研究旨在探讨饲粮添加干洋葱和干肉桂对鹌鹑产蛋性能、蛋品质、血清脂质谱和免疫反应的影响。选用 12 周龄产蛋鹌鹑 120 只，随机分为 5 组（每组 24 只），采用完全随机设计，每个处理设 4 个重复，每个重复 6 只鹌鹑。饲粮处理如下：对照组（基础饲粮，不添加任何物质）；泰乐菌素组（基础饲粮+100 mg/kg 泰乐菌素）；洋葱组（基础饲粮+800 mg/kg 干洋葱）；肉桂组（基础饲粮+800 mg/kg 干肉桂）；洋葱+肉桂组（基础饲粮+400 mg/kg 干洋葱和干肉桂混合物）。与对照组相比，肉桂组显著提高了鹌鹑的产蛋率、蛋数、蛋重和饲料转化率（P<0.05），其次是泰乐菌素组。与仅添加肉桂的饲粮相比，饲粮中添加洋葱+肉桂混合物的鹌鹑的蛋壳比例更高（P<0.05）。血清总脂质含量、蛋黄脂质和蛋黄胆固醇在添加饲粮的鸟类中均低于对照组（P<0.05）。另一方面，饲粮补充剂对甘油三酯和高密度脂蛋白水平没有影响。与对照组相比，饲粮添加洋葱和/或肉桂降低了血清丙二醛水平。与其他试验组相比，洋葱组的跗跖网指数更高（P<0.05）。干肉桂和干洋葱+干肉桂混合物组的免疫球蛋白 M（IgM）水平均显著高于对照组（P<0.05）。综上所述，饲粮添加干洋葱和干肉桂等天然植物材料可以改善鹌鹑的产蛋性能、蛋品质和免疫力。
