本研究的目的是确定不同剂量的维生素C在选定的孵化日期注射到肉种鸭和北京鸭的蛋中对孵化率的影响。分别于孵化后第13、15、17天（鸡3、6 mg）和第12、20天（鸭4、8 mg）在空气池中注射维生素C。在鸡的孵化率方面，对照组和试验组之间没有显著差异，尽管在孵化第15天注射6毫克维生素C的组确定受精卵的孵化率最高。另一方面，在鸭的孵化率方面，对照组和试验组（在孵化第12和20天注射4 mg维生素C，在孵化第20天注射8 mg维生素C）之间存在显著差异。注射抗坏血酸组的这一性状值高于未注射抗坏血酸组。平均而言，这一差距达到32.5个百分点。同样，在胚胎死亡数和未孵化雏鸡数方面，上述试验组的结果更好。综上所述，注射维生素C对鸡蛋的孵化率没有影响。以鸭蛋为例，在孵化第20天注射选定剂量的维生素C（4和8毫克/蛋），通过降低死亡和未孵化胚胎的比例，提高了孵化率。
The aim of the investigation was to ascertain the influence of different doses of vitamin C injected at selected dates of incubation into the eggs of broiler breeders and Pekin ducks on hatchability. The injected vitamin C doses were administered into the air cell on the 13th, 15th and 17th days (3 and 6 mg - chickens) and on the 12th and 20th days (4 and 8 mg ducks) of incubation. In the case of chickens, no significant differences were recorded between the control and experimental groups with regard to hatchability, although the highest value of hatchability from fertilized eggs was determined in the group injected with 6 mg of vitamin C on the 15th day of incubation. On the other hand, in ducks, significant differences were found between the control and experimental groups (4 mg of vitamin C administered on days 12 and 20 and 8 mg of vitamin C injected on day 20 of incubation) regarding hatchability. The value of this trait was higher in the group of eggs injected with ascorbic acid in comparison with the eggs which were not treated. On average, the difference amounted to 32.5 percentage points. Similarly, in the case of the number of dead embryos and unhatched chicks, better results were observed in the above-mentioned experimental groups. In summary, vitamin C injected into chicken eggs failed to influence hatchability. In the case of duck eggs, it was demonstrated that their injection on the 20th day of incubation with selected doses of vitamin C (4 and 8 mg/egg) improved hatchability by decreasing the proportions of dead and unhatched embryos.
