The research objective was to demonstrate the course of Vitamin C synthesis process in geese from the 1st to the 56th day of life as compared to the growth of organ and body mass. The level of Vitamin C was determined according to Roe-Kuethers method in the glandular stomach, jejunum, kidneys and spleen. It was proved that in geese in their embrional stage, the greatest amount of Vitamin C was synthesized by the kidneys - 214.5 mg/kg tissue, then the spleen - 212.6 mg/kg, a slighty lesser amount by the glandular stomach - 154.0 mg/kg and by the jejunum - 148.5 mg/kg tissue. In the first 56 days of life, the glandular stomach synthesized about 220 mg/kg tissue Vitamin C. The body mass growth was higher than glandular stomach mass (51.64 times and 15.91 times). It should be stated that the glandular stomach in this time period provides less and less Vitamin C. Intensive renal, spleen and jejunum mass growth (175.4 times, 380 times and 59.94 times respectively) caused a considerable increase of the Vitamin synthesis by the whole organs.
