PILARCZYK, R.; WOJCIK, J.; SABLIK, P. e CZERNIAK, P.. Fatty acid profile and health lipid indices in the raw milk of Simmental and Holstein-Friesian cows from an organic farm. S. Afr. j. anim. sci. [online]. 2015, vol.45, n.1, pp.30-38. ISSN 2221-4062. http://dx.doi.org/10.4314/sajas.v45i1.4.
The aim of this study was to compare the health-related fatty acid (FA) profiles and health lipid indices in the raw milk of Simmental and Holstein-Friesian cows from an organic farm. The milk from Simmental cows had a significantly higher content of C12:0, C16:1cis9, C17:1trans9, C18:2cis9,12 (LA), C18:3cis9,12,15 (LNA), C20:1cis9, C20:4cis5,8,11,14, n-6 PUFA, total polyunsaturated fatty acids (PUFAs) and unsaturated fatty acids (UFAs), and a lower content of C15:0, C18:0, C20:0, C22:0 and conjugated linoleic acid (CLA) in the total content of FA than the milk of Holstein-Friesian cows. The PUFA/SFA and UFA/saturated fatty acid (SFA) ratios in the milk from Simmental cows were significantly higher, whereas the thrombogenic index and the LA/LNA ratio were significantly lower compared with the milk of Holstein-Friesian cows.
