In five female goats breed on the 2nd and following lactations, changes were examined in dry matter and basic protein content as well as changes in correlation coefficients between the contents of amino acids found in colostrum from 2 to 72 hours after parturition. The most marked changes in average contents of total dry matter and proteins could be observed between 2, 12 and 24 hours after parturition. The content of total dry matter decreased from 23.8 to 17.5 %. On the other hand, casein nitrogen increased from 0.15 to 0.42 % and the casein number rose from 8.0 to 52.2 %. In spite of a high variability of AA contents in colostrum sampled in 2, 12 and 48 hours after parturition, the values of all correlation coefficients of AA contents in individual samples were found to be very high or high, and almost all positive.
