Supplemental Information

Pictures illustrating the three husbandry systems

On INTENSIVE farms heifers were kept in pens with fully slatted floor, on SEMI farms they were provided with a straw bedded lying area and on PASTURE farm heifers spent either the day or day and night on pasture.

Movements classifying standing and lying animals as being inactive or being active

Note that some movements could be classified as both the animal still being inactive and the animal becoming active based on the number of times this movement was shown (up to two consecutive times: classified as still being inactive, more than two consecutive times: classified as becoming active).

“Out of sight” for the different categories of the Inactivity Ethogram

The mean percentage of time (some parts of) the focal animals were recorded as “Out of sight” with respect to the different categories of the Inactivity Ethogram is presented per husbandry system.

Author Contributions

Sara Hintze conceived and designed the experiments, performed the experiments, analyzed the data, prepared figures and/or tables, authored or reviewed drafts of the paper, and approved the final draft.

Freija Maulbetsch performed the experiments, authored or reviewed drafts of the paper, and approved the final draft.

Animal Ethics

The following information was supplied relating to ethical approvals (i.e., approving body and any reference numbers):

Animals in this study were not manipulated; only their spontaneous behaviour was observed. According to Austrian legislation, the mere observation of animal behaviour is not defined as an animal experiment and does thus not require an experimental licence (Tierversuchsgesetz 2012).

Field Study Permissions

The following information was supplied relating to field study approvals (i.e., approving body and any reference numbers):

All nine farmers initially agreed to take part in the study, signed an informed consent form and approved the use of data from their farms for research purposes within the context of this study.
