Especially at the beginning of grazing, there are particular challenges for cattle farms when changing feeding. The following goals are pursued in scientific activity:

• Illustration of the changes in the forestomach pH value when switching from stable feeding to full pasture farming of dairy cows in the mountainous region of Austria
• Description of the daily and animal-specific courses of the pH value and the temperature of the forestomach contents
• Comparison of the rumen pH value or the course of different cow types (dairy or lifetime production)
• Development of basic data to derive recommendations for the optimal design of transitional feeding at the start of grazing
