ABSTRACT
The aim of the studies was to compare milk performance of Polish HF of the Black-and-White viariety cows managed under different housing systems. We have analysed two farms, A and B. The cows on the farm A were maneged in a free-stall system on a deep bedding, while those on the farm B were managed in confinement. The studies allowed concluding that the cows managed in the free-stall system achieved better life performance for milk (6788.2 kg), FCM (7712.2 kg), fat (334.5 kg), protein (226.5 kg), as well as percentage content of fat (4.88%) and protein (3.34%), as compared to those housed in confinement. The differences were significant at p ≤ 0.05 and p ≤ 0.01. The cows housed free were characterised by easier calvings and their calves were of stronger vitality compared to those housed in confinement.
