    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

    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
