Questionnaire on utilization of colostrum was carried out in 33 farms. Highest milking cow numbers were 20-40 heads in 45.5% of the farms. Calf numbers were 20-40 heads in 39.4% of the dairy farms and 40-60 heads in 42.4% of the farms. The amount of colostrum production per day was 20-30 kg in 30.3% of the farms and 30-40 kg in 30.3% of the farms. Colostrum intake per calf per day was 4 kg in 45.5% farms. Surplus colostrum after intake by calf was farms (85%) was wasted in 67% of the farms. More than 90% of dairy farms recognize an necessity to use surplus colostrum. Selling price of surplus colostrum was below 1,000 won per kg at 15 dairy farms and 1,000-2,000 won per kg at 4 dairy farms. Colostrum collection and use should be done by the dairy farms of antibiotics free. Quality control of colostrum should be done by testing antibiotics, microbacterium, chemical composition, somatic cells and etc. The colostrum is subjected to cool down below just after milking and process for the colostrum products.
