STUDY REGARDING THE INFLUENCE OF SEASON AND LACTATION ORDER ON MILK YIELD, MAJOR COMPONENTS AND SOMATIC CELL COUNT OF MILK

SUMMARY

The effects of lactation order and season on the milk production, chemical compositionand somatic cell number during a normal lactation (305 days) were studied. Researcheswere carried out on Romanian Black and White cows from the Didactical StationTimisoara. Cows calved in autumn and finished their lactation by the end of the nextyear. Milk production increased progressively in the second and third lactation, thusfat, protein and lactose yields increased, too. During the warm season (April-September) higher values for milk yield and major components of milk were recordedcompared to cold season. As a quality indicator, somatic cell count increase withlactation order, but reduces to half in cold season compared to warm season.
