| In a historical sense, current organic farming is an old-new alternative under changed world conditions. Organic dairying (O) is an alternative of friendly use of the environment in time of presupposed global climate changes. Potential impact of organic farming on raw cow-milk quality, composition and properties, as conpared to conventional milk production (C), were evaluatedin this paper on the basis of selectedm ilk indicators (MIs). Total solids, whey volume, pH of milk fermentation ability (FAM-pH), FAM streptococci, FAM noble lactic acid bacteria, I and Cu were higher in C milk (P<0.05). The alcohol stability (AS), titration acidity, curd firmness (CF), FAM titration acidity (FAM-T), Ca, P, Mg, K and Fe were higher in O milk (P<0.05).... |

| The effect of cows' diets on milk composition is discussed, focusing on those components of particular interest for human health. First dietary sources of fatty acids and their digestion and metabolism are reviewed. Then feeding factors affecting milk fat content and fatty acid composition are discussed, with emphasis on those factors related to forage and fat supplements. The effects of diet on protein content and composition and milk content of minerals and vitamins are reviewed. Feeding strategies for improving the nutritional quality of milk are summarized. |

| The fatty acid (FA) composition of bovine milk may be related to human health and technological properties of dairy products. The FA composition can be altered both through management and breeding. Large scale FA profiling of the Danish dairy cattle population has now been implemented for more than a year. For the first time access to millions of FA observations across an entire dairy population enables in depth analysis of the factors affecting the FA profile of milk. This was the aim of this study. For 12 months more than 3.5 million milk samples from four Danish dairy breeds had been analyzed using mid infrared spectroscopy and application of FOSS Application Note 64 for predicting content of seven FA groups and four individual FA. The results showed... |

| Dairy cows are very efficient in converting fibrous forages into nutritious foods for humans. However, when fed potentially human-edible feeds, such as grains and pulses, dairy cows show very low efficiency in terms of net food production. In this debate, by-products are often mentioned as high quality feeds with reduced human-edible fractions for dairy cows. The aim of this feeding trial was therefore to evaluate the effect of a full substitution of a common concentrate mixture (COM) with a mixture including solely industrial by-products (BP) on milk production, feed intake, and the edible feed conversion ratio (eFCR) in organic dairy production. Cows receiving the BP mixture showed higher intakes of fibre fractions and ether extract, while starch intake... |

| Raw milk offered for sale within and into the European Union has to be produced according to the requirements of Commission Directive 89/362/EEC and to meet quality standards described in Council Directive 92/46/EEC. Together the regulations say many things about the quality of milk and the hygienic means of production including guidance and requirements for: - The means of production, farm specifications etc. - Processes, milk handling - Animal health - Milk composition related to quality - especially antibiotics, cell count and bacterial content (Hillerton & Berry, 2004) Unpasteurized milk and the associated food products (yogurt, butter, cheese etc.) made from raw milk is safely produced and consumed in many areas around the world. Cheese... |

| Projektet SOBcows har i samarbejde med RYK gennem 16 måneder i 2015/16 analyseret for indholdet af 11 fedtsyrer/fedtsyregrupper i kontrolmælken fra alle ydelseskontrollerede køer i Danmark. Dataanalyser af godt 3,5 mio. mælkeprøver viser, at det er muligt at påvirke sammensætning af mælkefedtet gennem avl. En foreløbig beregning af arvbarheden hen over laktationen viser, at alle fedtsyrekategorier har en genetisk variation og enkeltfedtsyrerne har arvbarheder på højde med den samlede fedtydelse. Det betyder arvbarheder i intervallet 0,25-0,44 afhængig af race og paritet. De genetiske sammenhænge varierer betydeligt gennem laktationen og er påvirket af den øgede kropsmobilisering i de første måneder efter kælvning. En anvendelse af fedtstyrebestemmelserne i... |

| Eine der bedeutendsten Erkrankungen in der Milchviehherde ist die Euterentzündung. Die Ursachen der Mastitis sind vielfältig. Daher muss diesem Krankheitskomplex ein ganzheitliches Konzept entgegengesetzt werden. Um von einer Euterentzündung sprechen zu können, müssen Erscheingungen wie Rötung, Schwellung, Schmerz, vermehrte Wärme oder Abweichungen im Aussehen oder der Zusammensetzung der Milch vorliegen. Ist mindestens eines der angegebenen Symptome mit den fünf Sinnen des Menschen ohne Hilfmittel zu erkennen, spricht man von einer klinischen Euterentzündung (eine Flocke im Vorgemelk = klinische Mastitis!). Von größerer Bedeutung sind jedoch die weniger offensichtlichen Erkrankungen, die so genannten chronisch subklinischen oder unspezifischen... |

| Intake of dietary phytoestrogens has received a great deal of attention due to their potential influence on hormone-sensitive cancers such as breast and prostate cancer. Cow´s milk contains phytoestrogens and the content varies according to the composition of the feed and the type and amount of legumes used. In this study we evaluated the proliferative effect of milk with different phytoestrogen content in human breast (MCF-7) and prostate cancer cells (PC-3). Milk was obtained from cows fed either a birdsfoot trefoil-timothy silage based ration (B1) or two different red clover silage based diets (R1 and R2) resulting in total phytoestrogen contents of 403 ng/ml, 1659 ng/ml and 1434 ng/ml for the B1, R1 and R2 diets, respectively. Whey was produced from... |

| Reducing the amount of human-edible feed in livestock diets is a key factor towards more sustainable livestock systems. Based on results from a conventional wholesystem study comparing performance, efficiency, land productivity, and profitability of an indoor-feeding system (SH) and a pasture-based dairy production system (VW) in lowlands of Central Switzerland, the net contribution of these systems to human food protein and energy supply was analysed. Depending on the presumed human-edible fraction, the system VW produced between 6.6 and 11.2 times more human-edible protein and 3.5 to 6.6 times more human-edible energy via animal products than the animals consumed via feeds. For the group SH, these factors were clearly lower but still in a positive range... |

| In a whole-system study in lowland of Central Switzerland from 2007 - 2010 compared the performance, efficiency, land productivity and profitability of indoor-feeding (SH) dairy production with that of pasture-based feeding (VW) dairy production. In the present study these experimental results were economically evaluated under Austrian market und production conditions. Therefore conventional and organic model farms were created and analyzed using full cost accounting. In comparison to the barn feeding strategy a higher farm income, income per labor unit were achieved with the pasture-based feeding strategy. These economic differences were more pronounced under organic than conventional conditions. |

| Milk mineral matters are important in human nutrition, especially Ca, Mg and I. Increase of milk Mg along decrease of NPK soil fertilization under the Czech Republic (CR) conditions was predicted. This hypothetical prediction is based on antagonistic relationships between K fertilization, Mg level in cow roughage feeding and transfer of Mg into milk. In difference testing the conventional (C) cow milk was reference versus organic (O) milk. Holstein bulk milk samples (BMS) from winter and summer season in 4 C (n = 32 BMSs) and in 4 O (n = 16) herds were investigated. 6 herds were and 2 C were not grazed, other nutrition was typical under the CR conditions. Average MY of C herds was 7016±1068 and MY of O herds was 7037±422 kg per lactation. Macro- and... |
