This study investigates the potential of teaching gestating sows an individual sound signal to reduce aggression resulting from competition for feed access.

The study confirmed the biological mechanisms through immunological expression patterns according to stocking density.

This study proves the accuracy of accelerometer-based sow lying behavior classification and shows that free-farrowing systems benefit lactating sows.

An added aroma increased pigs’ exploration behaviour towards the foam, and thus could serve as a distraction when inside a confined foam box.

The study suggests lavender essential oil may improve the welfare of growing pigs. Inhalation of lavendar reduced the nasal microbiome diversity.

An hourly feeding regime could optimize sow productive performance, body condition, milk yield, welfare, and piglet growth in swine production.

Primiparous sow aggression may be reduced by increasing space allowance during gestation with social training during the growing period.

Dominance rank of an individual can be estimated according to the feeding order, body weight or parity if there is enough variability in the group.

Biological sex mediates, at least in part, the physiological response to heat stress.

Frequent emission of short sounds can reduce time spent sleeping and cause behavior changes. However, gestating sows can habituate to the sound stimuli and return to normal behavior.

Enrichment did not enhance the speed of recovery from challenges in pigs, although there were indications of reduced stress

Results suggested that farrowing pens with temporary crating facilitated mother-young interactions and showed a higher crushing rate.

The provision of nesting material to sows prior to farrowing can increase sow maternal care traits and piglet performance.

Environmental enrichment with cubes appears to have the greatest effect when applied post-weaning whereas flavor attractants appear to have the greatest effect when applied both pre- and post-weaning.

The use of cortisone and the estimation of 11β-HSD type 2 activity in hair is recommended instead of using hair cortisol concentrations alone.
