| The aim of this pilot prevalence study was to investigate the Oxacillin resistance of 73 Staphylococcus (S.) strains from 29 organic dairy farms in Lower Saxony. The strains were isolated from nasal mucosa and hand skin of milkers, herd bulk milk and mastitis milk samples. After strain identification, the Oxacillin resistance was measured by Etest. 23 strains were identified as S. aureus, four as S. hyicus, 15 as S. xylosus and 31 as other coagulase negative staphylococci. Because of their minimum inhibition concentration (mic) between 0.5 and 1 mg/mL four S. aureus isolates were assigned to borderline Oxacillin resistant S. aureus. Nine coagulase negative isolates had this property too. In total 19 staphylococci isolates had a mic > 1 mg/L and... |

| As a part of the study 'Health and performance of dairy cows in organic farming from an interdisciplinary point of view 13 an (intervention-) study on metabolic disorders and mastitis with regard to forage production, feeding management and husbandry practices' different udder health and metabolic variables were determined in 106 dairy farms in Germany between January 2008 and April 2010. The objective of this study was to evaluate udder health risks and metabolic risks in dry period and early lactation. Udder health and metabolic situation were similar to conventional dairy farms. Identified risks for metabolic health and udder health lay in the feeding area (homogenous feeding without a huge variation in body condition in lactation and dry period) and... |

| As a part of the study „Health and performance of dairy cows in organic farming from an interdisciplinary point of view – an (intervention-) study on metabolic disorders and mastitis with regard to forage production, feeding management and husbandry practices” quarter milk samples from cows at dry off and after calving were taken by farmers in 101 dairy farms in Germany between January 2008 and April 2010. The objective of this study was to evaluate mastitis prevalence at dry off and at calving and the evaluation of different therapeutic regimes at dry off. 3460 cows from 101 dairy farms were examined. Mastitis prevalence at dry off was comparable to conventional farms. At calving organic farms have high mastitis prevalence due to a low cure rate and a... |

The objective of this study was to evaluate mastitis prevalence at dry off and at calving and the evaluation of different therapeutic regimes at dry off. 681 cows from 86 dairy farms were examined. Mastitis prevalence at dry off was comparable to conventional farms. At calving organic farms have high mastitis prevalence due to a low cure rate and a high... |

| As a part of the study „Health and performance of dairy cows in organic farming from an interdisciplinary point of view – an (intervention-) study on metabolic disorders and mastitis with regard to forage production, feeding management and husbandry practices” different udder health and metabolic parameters were determined in 106 dairy farms in Germany between January 2008 and April 2010. The objective of this study was to evaluate and compare udder health and metabolic data in dry period and early lactation within the scope of a preliminary analysis. The analysis shows that relations exist between disturbances of the metabolism health and the udder health. Significant correlations between ketosis and hypocalcämia and udder health make clear that their... |
