    | Contributor(s):: Ko, Heng-Lun, Chong, Qiai, Escribano, Damián, Camerlink, Irene, Manteca, Xavier, Llonch, Pol

    Weaning and other regrouping events as routine work in commercial farms cause stress to pigs and compromise their welfare. Several studies found positive outcomes to mitigate weaning stress when piglets were socialized (i.e. co-mingled) or raised with enrichment materials in research settings....

  13. Impact of a cattle brush on feedlot steer behavior, productivity and stress physiology

    | Contributor(s):: Park, Rachel M., Schubach, Kelsey M., Cooke, Reinaldo F., Herring, Andy D., Jennings, Jenny S., Daigle, Courtney L.

  15. Clinical and behavioural consequences of on-farm mixing of cull sows after weaning

    | Contributor(s):: Herskin, Mette S., Holm, Cathrine, Thodberg, Karen

    In modern pig production up to 50% of the sows are slaughtered each year.

However,...
