The aim of the research was to investigate changes of some biochemical parameters in blood, milk and urine in Lithuanian Black and White cows during the indoor period. The experiment was carried out during the indoor period at the Centre of Practical training and experiments of the Lithuanian Veterinary Academy. Three analogous groups of the Lithuanian Black and White dairy cows according to the lactation, time of calving and productivity were formed during the experiment. For the cows forages were mixed and divided as a mixture by a mixer-divider Optimix**TM. The proportion of concentrates was given to each cow individually according to the productivity. Blood samples were taken from the ear vein before morning feeding, at two and four hours post feeding. Samples of urine from dairy cows with different productivity were collected after morning feeding and analyzed during one hour period by a Multistix 10 SG test (USA). Milk fat, milk protein and lactose were measured by equipment LactoScope FTIR (FT1.0. 2001; Delta Instruments, Holland).
