At white graded up goats from farm in Kujawsko-Pomorskie Province (Poland) was examined milk yield, chemical composition of milk and somatic cells with regard of influence of goats age and of lactation period. Greatest milkiness was at goats in four lactation (x=645 kg) and least in first lactation (x=483 kg). Fat content in milk was greatest at the beginning and in top every lactation, protein in last and lactoses in first months of milkness. Influence of goats age on chemical composition milks didn't ascertain. Content of somatic cells in milk was little at young goats (257 000/1 ml in I and 328 000/1 ml in II lactation) and increased together with age (648 000/1 ml in III and 645 000/1 ml in IV lactation)
