Stoffwechselbelastungen zu Laktationsbeginn und ihr Einfluss auf die Eutergesundheit in ökologisch wirtschaftenden Milchviehbetrieben

Summary

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 control is vital for animal health management in organic dairy farms.
