We evaluated 59 farms with Holsteins (H) and 77 with the Czech Fleckvieh breed (C).In our survey, only 44.1% of farmers evaluated the quality of colostrum (39% of C farms, 50.9% of H farms). Uncontrolled quality of colostrum is a major shortcoming in the colostrum management. We described the advantages and disadvantages by using of a refractometer and colostrometer, included interpretation of results (in accordance with international scientific papers). In total, 73.5% of all breeders had frozen stocks of colostrum (72.7 % of C farms and 74.6 of H farms). Insufficient stocks of colostrum indicate insufficient knowledge as to the importance of timely feeding of calves with colostrum.
