This investigation aimed to evaluate the impact of immersion (IM) riboflavin treatment on the hatchability, production efficiency, and carcass characteristics of Japanese quail eggs. A total of 260 eggs of Japanese quail birds were used for hatching and were randomly divided into 4 treatments with 5 replicates (13 eggs/replicate) in a fully randomized design. Hatching eggs were immersed in riboflavin for 2 min before incubation. The experiment treatments were designed as follows: G1 control group with no treatment, G2 treated with 3 g/L vit. B2 (IM), G3 treated with 4 g/L vit. B2 (IM) and G4 were treated with 5 g/L vit. B2 (IM). After hatching, 128 Japanese quail chicks, aged 7 d, were randomly grouped into 4 treatment groups, with 32 birds in each group. When quails were given vitamin B2 via immersion, they demonstrated significant enhancements in live body weight, body weight gain, feed consumption, and feed conversion ratio at different stages compared to the control group. Compared to control and other groups, the carcass parameters of Japanese quails given a 4 g/L immersion solution showed a significant improvement (P < 0.05). Hatchability and fertility (%) were considerably raised by Vit.B2 treatments of 3, 4, and 5g; the group immersed in 5 g/L had the highest percentages compared to the other groups. Furthermore, treated chickens with all concentrations of vitamin B2 had significantly higher blood indices than the controls. During the exploratory phase (1-6 wk) of age, the highest returns were reported in G4 treated with 5g/L vit. B2 (IM). Treating Japanese quail eggs with different dosages of vitamin B2 by immersion may be recommended to improve their productive and reproductive performance, blood indices, carcass traits, and economic efficiency.
本研究旨在评估浸泡（IM）核黄素处理对日本鹌鹑蛋孵化率、生产效率和胴体特性的影响。共有 260 枚日本鹌鹑蛋用于孵化，并采用完全随机设计，将其随机分为 4 个处理组，每个处理组有 5 个重复（每个重复 13 个蛋）。孵化蛋在孵化前用核黄素浸泡 2 分钟。实验处理设计如下：G1 对照组无处理，G2 用 3 g/L 维生素 B2（IM）处理，G3 用 4 g/L 维生素 B2（IM）处理，G4 用 5 g/L 维生素 B2（IM）处理。孵化后，将 128 只 7 日龄日本鹌鹑雏鸡随机分为 4 个处理组，每组 32 只。当鹌鹑通过浸泡摄入维生素 B2 时，与对照组相比，它们在不同阶段的活体体重、体重增加、饲料消耗和饲料转化率都有显著提高。与对照组和其他组相比，4 g/L 浸泡液组的鹌鹑胴体参数有显著改善（P<0.05）。3、4 和 5 g Vit.B2 处理的孵化率和受精率（%）显著提高；与其他组相比，浸泡在 5 g/L 的组百分比最高。此外，所有浓度维生素 B2 处理的鸡的血液指数均显著高于对照组。在 1-6 周的探索阶段，用 5 g/L Vit.B2（IM）处理的 G4 组的回报率最高。用不同剂量的维生素 B2 浸泡日本鹌鹑蛋可能有助于提高其生产和繁殖性能、血液指数、胴体特征和经济效益。
