The research was performed on 100 cows of Black and White Polish Holstein-Friesian breed. The studied cows were under a visual and tactile evaluation of body condition using a BCS (Body Condition Scoring) method performed on the day of parturition as well as 30th day of lactation. The observation results of the body condition changes during that period were juxtaposed with FPR. The value of that indicator was determined on the base of control milking performed on the 30th day of lactation. The aim of the research was defining the relationship between the value of FPR and the changes of cows’ body condition between the day of parturition and 30th day of lactation. The statistically significant differences (P < 0.05) of FPR value in dependence of the changes in cows’ body condition between the parturition day and 30th day of lactation were determined.
