Fatty acids and composition of their important groups in milk fat of Czech Pied cattle
Original language description
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 acidswas 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 co

Czech description
Rozdíly v zastoupení mastných kyselin mléčného tuku byly zjišťovány u dojnic plemen český strakatý a holštýnský skot v květnu 2003, červenci 2004 a únoru 2005. Statisticky významné rozdíly byly zjištěny v roce 2003 v obsazích kyseliny kaprinové (C10:0),stearové (C18:0) a olejové (C18:1); v roce 2004 u kyseliny kapronové (C6:0), myristolejové (C14:1) a stearové (C18:0); v roce 2005 u kyseliny myristolejové (C14:1) a palmitolejové (C16:1). Klíčová slova: český strakatý skot, mléčný tuk, zastoupení mastných kyselin
