Partial effect plots of the effect regarding the number of previous handlings on stress indices representing HPA axis- and SNS-activity as well as LCC in summer (a and c) and winter (b and d) extracted from the respective best models (see additional Table A1). Significant effects (i.e., slope significantly different from zero) are indicated by bold lines, the non-significant effect of the number of handlings on LCC with a thin line annotated with “ns”. P-values and other statistical parameters are given in additional Table A1. Colours and line types of regression lines and y-axes indicate the various stress indices. Only stress indices where the number of previous handlings showed a significant effect in at least one season are displayed
