摘要

本研究旨在评价卵内注射氧化锌纳米颗粒对肉鸡孵化能力、生产性能和免疫反应的影响。使用从罗斯308肉鸡繁殖群获得的总共192个可育蛋。将鸡蛋分为4个实验组，包括阳性对照组，注射生理盐水，并在培养期的第一天在空气细胞中注射50、75和100ppm的纳米ZnO，并将其放置在培养箱中。孵化的小鸡被分配到一个完全随机的设计中，有4个处理和4个重复，用于42天的实验。与对照组相比，卵内注射纳米ZnO提高了鸡蛋的孵化率（p0.05）。10日龄时对流感病毒的抗体滴度结果在实验处理之间没有差异（p>0.05），10日龄肉鸡血液中单核细胞和红细胞压积数无显著差异（P>0.05），卵内注射纳米氧化锌对雏鸡的生产性能没有明显影响。

The Effect of in ovo Supplementation of Nano Zinc Oxide Particles on Hatchability and Post-Hatch Immune System of Broiler Chicken

The aim of this study was to evaluate the effects of in ovo injection of zinc oxide nanoparticles on the hatchability, production performance and immune responses of broilers. A total of 192 fertile eggs obtained from a Ross 308 broiler breeder flock were used. The eggs were divided into 4 experimental groups including a positive control group with normal saline injection, and injection of 50, 75 and 100 ppm nano-ZnO on the first day of incubation period in the air cell and were placed in the incubator. The hatched chicks were allocated to a completely randomized design with 4 treatments and 4 replicates for a 42-day experiment. In ovo injection of nano-ZnO increased hatchability of eggs compared to the control group (p 0.05). The results of antibody titer against the influenza virus at 10 days of age did not differ between the experimental treatments (P>0.05). The heterophil, lymphocytes, monocytes and hematocrit number in the blood of broiler chickens at 10 days of age did not show any significant difference (P>0.05). The results of the present study suggest that in ovo injection of nano ZnO particles had positive effects on early embryo mortality rate, total white blood cells, however the performance traits of the hatched chicks were not significantly affected through in ovo injection of nano ZnO particles.
