| The objective of the study was (i) to compare the nutritional composition of milk produced in organic and conventional production systems taking into consideration: different proportions of grass or grass silage, maize silage and different amount of concentrate (cereals), and (ii) to define the variation in content of pro- and antioxidants in milk in relation to regional variation, feeding and season. The feeding regime from 25 farms from Denmark, 20 farms from Sweden and 25 farms from United Kingdom was reg-istered and milk samples were collected and analysed for the content of antioxidants and fatty acid compo-sition. The daily milk production was significantly higher in the conventional milk production systems in the two Scandinavian countries compared... |

| BACKGROUND: Previous studies showed differences in fatty acid (FA) and antioxidant profiles between organic and conventional milk. However, they did not (a) investigate seasonal differences, (b) include non-organic, lowinput systems or (c) compare individual carotenoids, stereoisomers of α-tocopherol or isomers of conjugated linoleic acid. This survey-based study compares milk from three production systems: (i) high-input, conventional (10 farms); (ii) low-input, organic (10 farms); and (iii) low-input non-organic (5 farms). Samples were taken during the outdoor grazing (78 samples) and indoor periods (31 samples). RESULTS: During the outdoor grazing period, on average, milk from the low-input systems had lower saturated FAs, but higher mono- and... |
