Abstract: Sonographic images of the ewe left and right udder cisterns using 2 methods (1 – from side, 2 – from bottom) were taken by means of two devices: an ultrasonograph Aloka 250 (3,5 MHz linear probe) or ultrasonograph SonoVet2000 (L2-5/170 CD linear probe). Length, width and area of each udder cistern were measured during milking period in years 2002 to 2008. The ewes of 5 genotypes (purebred Tsigai, purebred Lacaune, crosses of Tsigai with Lacaune and East-Friesian with genetic portion of specialized dairy breeds 25 %, 50 % and 75 %) were evaluated. According to measured traits, 640 and 752 sonograms from 200 and 231 ewes were taken using the method 1, and 470 sonograms from 163 ewes were taken using the method 2. Data were evaluated using REML methodology and MIXED procedure (software SAS/STAT). The effect of genotype showed the highest influence (P
