title: [Investigation of metabolic parame- ters in high yielding dairy cows in pasture based production systems].
abstract: In the present study differences in metabolism between New Zealand Holstein-Friesian (NZHF) and Brown Swiss (CH-BV) or Swiss Holstein-Friesian (CH-HF) were investigated in a grassland based milk production system in Switzerland. Therefore 14 pairs of CH-BV/NZHF and 11 pairs of CH-HF/NZHF were available. The parameters glucose, insulin, non-esterified fatty acids (NEFA), β-hydroxybutyrate (β-HB), urea and cholesterol were analysed at the times 5-3 weeks before the calculated partus and 2, 3, 5, 7, 10 and 18-22 weeks post partum. Only β-HB showed significantly higher concentrations (P = 0.0059) for both Swiss breeds compared to the NZ-HF. Regarding all other physiological parameters during early lactation New Zealand Holstein-Friesians were not different from Swiss breeds.
