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.
