| According to the results of human health researches the causes of the leading diseases (heart- and cardiovascular system, malignant tumours) show a close relation with human nutrition. Therefore the topic of animal origin product quality affecting the human health receives increasing attention. The content and proportion of the saturated and unsaturated fatty acids and the content of vitamins and macro- and micro elements are in the centre of interest, which justify the present study. In the background of the consumers’ decision making concerning organic food. They are wholesomeness, together with it high quality and being chemical-free, so that is why they can be considered primary consumers expectations. Due to the composition of organic milk it can... |

| 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... |

| Various recent studies have indicated positive interactions between organic animal production and poly-unsaturated fatty acids, particularly CLA and omega-3. In this paper, we present the monitoring results of 15 organic farms concerning the rela-tionship between feeding practices and fatty acid pattern. The results indicate a strong negative effect of maize and grass silage and concentrate feeding on CLA levels in milk fat. On the other hand, feeding fresh grass has a positive effect. Omega-3 levels in milk fat seem less related to feed characteristics: similar relations to those with CLA seem to exist, but feed composition explains the variation in omega-3 levels only to a limited extent, while there is a large farm influence. This might be related to... |

| A continuous grazing experiment with three measurement periods, 3 weeks each, was conducted with 16 Norwegian Red dairy cows in mid lactation to compare milk quality when grazing red clover-grass (R) or botanical diverse pasture (D). The cows were offered either R or D from the start of grazing season in mid May until beginning of September 2008. Milk yield was measured and milk samples were collected in the last week in each period (end of June, beginning of August and end of August). Pasture type had no effect on milk yield and milk content of fat or protein. Cows grazing R had higher proportion of the fatty acids C18:0 (22.41 vs. 9.96, P<0.05) and C18:1t11 (0.58 vs. 0.44 g/100g FAME, P<0.05) and lower proportion of C16:0 (27.83 vs. 30.92,... |

| In het verleden is al aangetoond dat de biologische productiemethode maatschappelijke voordelen heeft op terreinen als milieu, biodiversiteit, bodemkwaliteit, dierenwelzijn en pesticidenresidu. Indirect dragen deze kwaliteiten bij aan de gezondheid van de mens. Nu beginnen ook steeds meer onderzoeksresultaten beschikbaar te komen waaruit blijkt dat de biologische productiemethode ook leidt tot voedsel dat meer gezonde stoffen bevat. Biologische producten blijken gemiddeld gelijk of hoger te scoren op gezonde stoffen o.a. vitamine C gehaltes, mineralen, anti-oxidanten en eiwitkwaliteit dan reguliere producten. En biologische producten blijken gelijk of lager te scoren op ongezonde stoffen zoals nitraat, residuen van bestrijdingsmiddelen en... |

| Problematikken omkring råmælksoste er, at det ikke er tilladt at producere dem i Danmark, men kun at importere dem. Det skyldes de danske myndigheders fortolkning af det EU-direktiv (92/46/EØF af 16. juni 1992), som fastsætter reglerne omkring produktion og behandling af rå mælk. De danske myndigheder mener, at konsum af råmælksoste giver øget sundhedsrisiko og derfor ikke bør produceres, da det ikke er muligt at opretholde en tilfredsstillende hygiejne uden at varmebehandle mælken. Dette har givet anledning til debat gennem tiden, da nogle mejerister og kendte kokke mener, at råmælksoste smager bedre end pasteuriserede oste og derfor kan give levnedsmiddelindustrien et kvalitetsløft. Formålet med opgaven er derfor at undersøge, om og hvordan det er muligt... |

| Versuch I: Aktuelle Erhebung über die Milchqualität von ökologisch wirtschaftenden im Vergleich zu konventionell wirtschaftenden Betrieben Ziel des Versuches war es, verschiedene betriebliche Gegebenheiten und die Milchqualitätsparameter von ökologisch und von konventionell wirtschaftenden Betrieben gegenüberzustellen, zu vergleichen und die Unterschiede zu begründen. Dafür wurden 15 ökologisch und 13 konventionell wirtschaftende Milchviehbetriebe in Westfalen ausgewählt und um ihr Einverständnis gebeten, an dieser Untersuchung teilzunehmen. Zunächst erfolgte die Anfertigung der für die Befragung erforderlichen Checklisten für die Produktionsbereiche Melken, Fütterung, Haltung und Management. Nach Fertigstellung der Checklisten wurden die Betriebe... |

| Vitamins in milk are important for the human consumer, the calf and the cow. They are also important for the dairy industry because some of them affect the risk for off-flavour. Studies indicate that milk from organic and conventional dairy farms may differ in these aspects. The aim of this study was therefore to investigate whether there are differences in the concentration of vitamins and selenium in milk between organic and conventional farms in Sweden. Bulk tank milk was sampled in 20 organic and 20 conventional dairy farms at three occasions during the indoor season. Concentrations of α-tocopherol, β-carotene and retinol were determined by HPLC and selenium by hydrid generation inductively coupled plasma atomic emission spectrometry. Herd... |

| Bulk-tank milk was collected each month from organic (n=17) and conventional (n=19) dairy farms in the UK for a 12-month longitudinal study. All milk samples were analysed for fatty acid (FA) content. The effects of farming system type, herd production level and nutritional factors on the FA composition were investigated by use of mixed model analyses. Models were constructed for saturated fatty acids (SFA), the ratio of poly-unsaturated fatty acids (PUFA) to mono-unsaturated fatty acids (MUFA), total omega-3 FA, total omega-6 FA and conjugated linoleic acid (CLA). Organic milk had a higher proportion of PUFA to MUFA and of omega-3 FA than conventional milk, and contained a consistently lower omega-6:omega-3 FA ratio, considered to be beneficial, com-pared... |
