Figure Legend Snippet: Injuries, weakness and mortality of piglets/pigs as husbandry invasive surgical procedures were gradually avoided and meaningful environmental enrichment was provided. ( a ) Mixed effects Poisson Regression Coefficient analysis of injuries occurrence in Groups 2-4 (G2-4) as compared to the control group (Group 1; G1); data is presented as coefficient (sign) and 95% confidence interval (bars). ( b ) Odds Ratio to be weak or dead in Groups 2-4 (G2-4) as compared to the control group (Group 1); data was analyzed by a chi-square goodness of fit test and the Binominal test, and is presented as Odds Ratio (sign) and 95% confidence interval (bars). In both panels, Group 1 is represented by the horizontal dotted line; values significantly differed ( P < 0.05) from Group 1 if the bar does not cross the dotted line.

Figure Legend Snippet: Hair and saliva cortisol concentrations in piglets/pigs, as husbandry invasive surgical procedures were gradually avoided and meaningful environmental enrichment was provided. Individual hair cortisol concentrations at weaning ( a ) and slaughter ( b ) were analyzed by Multi Variate Linear regression test (controlled for variables: mother cortisol, weaning weight and suckling period). Saliva was collected for cortisol measurements at the pen level, every two weeks from weaning to slaughter, and the results are presented in ( c ) and ( d ). ( c ) Samples were clustered together per group, without taking the sample date into consideration; a mixed effect linear regression model was used for statistical analysis (Random effect: pen. Predictor: treatment group. Adjusted for: tail biting, leg injuries, skin lesions, weakness and survival). ( d ) Analysis of saliva cortisol in Group 2-4, as compared to Group 1; for the statistical analysis, time varying group effects was applied, using log-level regressions on group identifiers and individual treatments, standard errors were clustered at the pen level. In all panels, data is presented as coefficient (sign) and 95% confidence interval (bars); Group 1 is represented by the horizontal dotted line; values significantly differed ( P < 0.05) from Group 1 if the bar do not cross the dotted line.
