Sažetak

The relationship between yield and milkabillty was investigated with the aim to find a possible basis selection of more cows to mastitis. In the herd of 60 Holstein-Friesian cows during 24 milkings (evening and morning) milk yield (electronic flowmeter) and milking time (stop watch) was measured. Milkabilities were calculated and cell counts were determined in milk samples (Fossomatic). Following results were established: - low milk yield and good milkability, cell count was the lowest (x = 55.000/ml); - low milk yield and poor milkability, cell count was low (x = 182.000/ml); - high milk yield and good milkability, cell count was higher, still acceptable (x = 224.000/ml); - high milk yield and poor milkability, cell counts was the highest (x = 341.000/ ml).
