    The subject of the planned investigations is a special manure removal system for calf boxes - the Moving Floor. In this project, in addition to the user-friendliness, the animal welfare aspect of the system will also be examined. In addition to temperature and humidity measurements, particular attention is paid to the quality of execution, energy consumption and also the price/performance ratio. The results of the study provide conclusions about the animal welfare of the system and can subsequently be used as a basis for discussion for farmers.

    Many farmers are interested in saving working time or making their work easier. This project attempts to clarify the question of whether the arrangement of the moving floor actually meets the strict requirements of animal protection.

    Test rooms:

    The calf box will be placed under a carport north of the HBLFA multi-purpose experimental barn. Depending on the weight of the calves, 3 or 4 calves are kept in the calf box.

    Origin of the animals:

    Breeding the herd at the HBLFA

    Feeding:

    Hay for free consumption, 0.5 kg/animal concentrate, water intake via heated drinker

    Litter:

    Automatic feed. Material: sawdust, straw in different lengths

    The following parameters are examined:

    - Temperature and humidity
    - Suitability of different bedding materials
    - Visual assessment and technical processing (recording the dimensions)
    - User-friendliness when feeding, watering, removing manure, changing stables and cleaning
    - Recording the time required for feeding and cleaning
    - Surveying the straw requirement
    - Daily assessment of the degree of contamination using photography
    - Video recording to analyze drinking, eating and lying behavior
    - Air consumption
    - Power consumption
    - Operational safety
