Changes in colostral levels of dry matter (DM), protein, fat, lactose and pH were folowed in 5 crossbred ewes of East-Friesian bred x improved Valachian sheep on the second and subsequent lactations within the time interval of 2 to 72 hours after parturition. Contents of DM, crude protein, true protein and fat decreased gradually from 29.97 to 18.58 %; 17.00 to 6.54 g/100 ml; 14.59 to 6.11 g/100ml and 9.83 to 6.86 g/100 ml, respectively. The content of lactose increased from 1.42 to 4.72 g/100 ml and the pH value fluctuated between 6.40 and 6.67. Average values of nutritional parameters under study were evaluated with regard to the length of postpartum period by means of regression analysis
