Quality improvement of Slovak ewe milk based on the content of health affecting fatty acid compounds

Popis výsledku v původním jazyce

The content of 70 C4-C24 fatty acids (FA) in bulk milk samples of dairy ewes at 4 farms during pasture season and at one farm during winter season was determined by gas chromatography. The FA content in milk fat of grazed ewes was higher up to 4-fold forrumenic acid (CLA), 3-fold for trans-vaccenic acid (TVA) and 2-fold for ?-linolenic acid (ALA) compared to that during winter diet. The content of CLA (3.5 %) and TVA (7.9 %) in milk fat of grazed ewes from Tajov farm was higher than that in milk of pasture grazed ewes or cows published previously. Nevertheless, the farm at Trenčianska Teplá because of lower altitude and corresponding climatic conditions in summer showed temporal variation up to 50 % lower content of CLA and TVA. The variations in CLAcontent during pasture season are primarily related to the seasonal changes of ALA content in pasture plants. These findings suggest that further development of ewes' milk production should be situated in the northern part of Slovakia at
