Abstract
The study was conducted on two family farms (herds A and B). The experimental materials comprised Polish Holstein-Friesian cattle raised in 2006–2009. The objective of this study was to compare SCC, the yield and composition of milk from Holstein-Friesian Black-and-White cows kept in the tie-stall and free-stall system for four years. The analysis indicates that cows housed in a tie-stall barn (herd A) were characterized by higher milk performance than cows kept in a freestall barn (herd B). Milk yield was correlated with SCC in milk in both herds. Yield increase in the A herd was connected with the SCC decrease. Such dependence has not been found in the herd B.
