The aim of the study was evaluation of productivity Holstein-Fresian cows imported from Sweden and Germany. The course of parturitions in the studied animals was also evaluated depending on sex and body weight of calf at birth. The investigations were carried out on a farm located in the Zachodniopomorskie Province. Cows imported from Sweden characterized by higher milk yield in the first 305-d lactation compared with their age mates from Germany. The differences were statistically significant at P ≤ 0.01. Animals from Germany were superior to the cows from Sweden with regard to fat yield, fat content and protein content. The differences were statistically significant at P ≤ 0.05. Cows imported from Germany characterized by favourable fertility parameters compared with their Swedish age mates.
