Effects of in ovo injection of Q10 on hatchability, performance (feed intake (FI), body weight gain (BWG), feed/gain ratio (F/G)) traits, and immune status of Ross × Ross 308 broiler chicks, hatched from eggs laid by a 38-week-old breeder flock, were determined through 42 days after hatch. Eggs containing live embryos were injected in the amnion with 0.1 and 0.2 mL Q10 solution on day 18 of incubation. Two controls groups were included as sham and/or as an uninjected group. At 28 and 42 days of age, performance traits, serum enzyme activity, weights of immune organs, and serum antibody titer of viral diseases were determined. Results were shown that hatchability % increased by Q10 on average of 6.54% (P≤0.025) and body weight/egg weight after hatching increased up to 4.74% (P≤0.002), compared with uninjected and sham controls. Injection of Q10 at different levels led to significant increases (P≤0.001) in performance traits all over the rearing period (P<0.05). Weight of immune organs significantly improved compared to uninjected and sham controls (P<0.05). In addition, serum antibody titers of viral diseases as well as serum enzyme activity of AST, ALT, CAT, and SOD were significantly changed by Q10 treated groups than controls (P≤0.01). In conclusion, in ovo injection of Q10 at levels of 0.1 and 0.2 mL led to significant increases in hatchability%, internal egg characteristics, and performance parameters as well as serum enzyme activity, weight of immune organs, and serum antibody titer of ND, AI, and IBD diseases.
在孵化后第 42 天，通过对罗斯 308 肉鸡雏鸡进行孵化，研究了在孵化第 18 天向鸡胚羊膜腔中注射 0.1 和 0.2mlQ10 溶液对孵化率、生产性能（采食量（FI）、体重增加（BWG）、饲料/增重比（F/G））、免疫状态的影响。本试验包括两个对照组，即假注射组和未注射组。在 28 和 42 日龄时，测定了生产性能、血清酶活性、免疫器官重量和病毒性疾病血清抗体滴度。结果表明，与未注射组和假注射组相比，Q10 组的孵化率平均提高了 6.54%（P≤0.025），孵化后体重/蛋重提高了 4.74%（P≤0.002）。在整个育雏期，不同水平的 Q10 注射均显著提高了生产性能（P≤0.001）（P<0.05）。与未注射组和假注射组相比，免疫器官重量显著提高（P<0.05）。此外，与对照组相比，Q10 处理组的病毒性疾病血清抗体滴度以及血清酶活性 AST、ALT、CAT 和 SOD 显著改变（P≤0.01）。总之，在 0.1 和 0.2ml 水平对鸡胚进行 Q10 注射可显著提高孵化率、卵内特性和生产性能参数以及血清酶活性、免疫器官重量和 ND、AI 和 IBD 疾病的血清抗体滴度。
