Impact of seasonal pasture on fatty acid composition of cows milk
Result description
Bulk milk samples from a low-input mountain farm (at 575 m a.s.l.) in the Czech Republic were analyzed for fatty acid composition. Five milk samples were collected in a pasture period and four samples in a period of confinement. The proportion of a majorcis-9, trans-11 isomer of conjugated linoleic acid (CLA) was higher whereas proportion of myristic (14:0) and palmitic acid (16:0) was lower in a pasture period than in a confinement period (1.01; 9.56; 26.12 vs. 0.56; 11.76; 35.43 %, arithmetic means,respectively; P < 0.05). The proportion of total unsaturated acids was higher in a pasture period than in a confinement period (36.40 vs. 28.57 % on average, respectively; P < 0.01). Positive changes in fatty acid profile in terms of human health were thus confirmed in milk from grazing cows. In: Alternative Functions of Grassland, Research Institute fo Fodder Crops Ltd.
