A characteristic feature of the organic system of production is the lower productivity of cows. The aim of the study was to determine the effect of cow age and collecting number on the level of immunostimulating colostrum components in an organic farm. From the basic herd specializing in organic milk production, 40 cows of the Polish Holstein-Friesian Black and White breed were selected: 10 primiparous, 10 cows in 2nd lactation, 10 cows in 4th lactation and 10 cows in 5th lactation. The colostrum samples were collected according to the following scheme: the first one maximum of two hours after calving, the second on the same day and the third and fourth on the following day. For three consecutive days samples were taken once a day (7 colostrum samples from each cow). Statistically significant differences in the level of bioactive components of colostrum with immunostimulating properties has been shown due to the time of intake from calving and significant differences in the level of these components due to the age of cows. Multiparous cows synthetized colostrum with a higher content of total protein, casein and non-fat dry matter than the primiparous. Variability of the immunoglobulin content of colostrum obtained in 1st and in the 2nd collecting after calving was higher in multiparous cows than in primiparous cows. Furthermore, it has been shown that there was a clear correlation between the quality of colostrum and the age of cows. In conclusion, a high impact of the interaction of age of cows x collecting number on the development of colostrum stimulating ingredients in the organic production system has been demonstrated.
