Research was carried out at two localities ecologically different, i.e. in the "relatively" clean region of Klatovy, designed according to the standards of the Czech Ministry of Environment as a region with above-average quality environment and in the considerably affected region of Prague-East, designed as a region with below-average quality environment. The first group included 33 cows from herds with good fertility (average conception rate after 1st insemination 61.5 and service period 88 days) and the dairy cows were eliminated for reasons different as reproductive disorders (Klatovy), in the second group all 18 cows were eliminated because of reproductive disorders (Prague-East) and they were from the herds with much lower fertility (average conception rate after 1st insemination 46.9% and service period 107 days). Samples of liver, uterus and ovarian tissues of the cows were processed according to the method after Jarý et al. (1987), analysed on the gas chromatograph Varian--Aerogramm 2100. The data obtained were processed on a computer IBM PC--AT with a numeric co-processor, and the programme Quatro Pro, version 2.0 was used. Differences in average amounts measured in both regions are objectively characterized in Figs. 1, 2 (with marked scatterings) and correspond to the amount given in Tab. I. As regards the saturated acid, stearic acid and oleic acid, no remarkable differences were found according to the localities (Klatovy and Prague), with the exception of the average contents of those acids in uterine horns. In that case the region of Klatovy is dominating.
