Summary

Research was carried out on 40 one- to three-year-old (the 1^st to 3^rd lactation) F| crossbreeds of East Friesian and Polish Merino on the Experimental Station at Koluda Wielka situated in the lowlands of central Poland. The ewes were milked mechanically twice a day during a period of 4 months (May - September 1997) after the weaning of 8-week-old lambs. The measurements of the udders, the milk yield, the chemical composition and the somatic cell number were taken during the milking period, in the 10^th, 16^th and 22^nd weeks of lactation. The udder sizes of the older ewes were larger than those of the Primigravidae (by 4 - 7%) and their milk yields were also larger, by 13% in two-year-old ewes and by 8% in three-year-old ones. The udders shrank by 4 - 28% between the 10^th and 22^nd week of lactation (especially in width, length and circumference), and the daily milk yield dropped by 57% at the same time. Along with the lactation development, the contents of protein, fat and dry matter in the milk increased, and the lactose content, the SFA : NSFA ratio and the somatic cells count became smaller. The milk yield was statistically significant when correlated with the udder measurements: the circumference (r = 0.53), width (r = 0.52) and depth (r = 0.39).
