title: [Physiologic parameters and locomotor activity in Fleckvieh and Schwarzbund cattle during an alpine summer].
abstract: The investigation on an alpine pasture was performed on 15 heifers of the breeds Fleckvieh and Friesians from different farms. Some physiological parameters and locomotor activities in dependence of breed, farm of origin and weather conditions were studied. Animals of one farm were pastured in spring, the animals of the other farm were brought directly from the barn to the mountain area. Physiological parameters were influenced by farm, but not by breed. The activities of GOT and CK increased in unprepared heifers only (due to the release from skeletal muscles) as did levels of free fatty acids and beta-hydroxybutyrate obviously due to adaptation-difficulties linked with energy-deficiency. Pre-pastured animals showed higher blood-urea concentrations, due to their ability to locate always fresh grass with high protein content. The breed influence on the daily number of steps and on the distance covered was statistically not significant. Animals already pastured in spring showed more movement than unprepared ones. Among weather conditions thunderstorm showed a striking increase in activity which resulted from the search for shelter. On rainy days without wind the animals showed least movement. Cloudy, dry weather as well as sunshine was associated with average activity. These reactions to meteorological conditions were manifested more clearly in prepared heifers. The other animals obviously had to learn first how to minimize untoward effects by suitable behaviour.
