"In 2003, 2004 and 2005 milk fat composition was determined three times in 55 dairy cows of Czech Pied cattle housed in a byre with stanchions and fed under conditions usual at Czech production farms. Fatty acids were determined by a gas chromatographic method, 26 acids out of the total 37 acids observed in chromatograms were identified. The highest proportions were observed for palmitic acid (29.25 +/- 2.98 %), oleic acid (24.47 +/- 3.27 %), myristic acid (12.14 +/- 1.80 %) and stearic acid (8.91 +/- 2.44 %). The proportions of saturated, unsaturated and monounsaturated fatty acids were 64.71 +/- 4.18, 31.96 +/- 4.20 and 27.45 +/- 3.42 % of total acids, respectively. The total proportion of nutritionally undesirable lauric, myristic and palmitic acids was 45.26 +/- 4.77 %, while that of the desirable group of polyunsaturated fatty acids was 4.51 +/-1.09 %. The observed relatively wide ranges of the individual groups of fatty acids indicate that it is possible to improve the milk fat composition in Cze" .
