- Infl uence of cattle breed and country of origin on milk yield and milk composition in dairy cows. Dairy cattle breeding and milk industry are still signifi cant part of Polish agriculture industry. Polish farmers have valid positions in Europe and other parts of the world and cattle is their main source of income but also main species using grasslands in Poland. The main objective of the study was to determine the effect of: race, herd, country of origin and number of calving on milk production and milk composition of three dairy cattle breeds: Polish Holstein-Friesian, Polish Black and White, Simmental. Cows were kept on farms with milk performance recording system. Importance of each factor was assessed using one-way analysis of variance. Polish Holstein- Friesian breed achieved the highest daily milk yield (P < 0.01). The highest milk yield cows reached during the 3rd lactation. However, cattle imported from the Netherlands had higher (P < 0.01) milk yield, protein content and somatic cell count level comparing to cows from other countries. Presented data may suggest that breeders in the Netherland remove from herds cow more susceptible to mastitis. Farmers in Poland should consider breeds different than PHF e.g., SM if having large grasslands.
