Weaning Sows Directly into Group Housing: Aggression, Welfare & Production

Social stress from mixing sows has the potential to negatively affect sow production and welfare. Housing sows in stalls from weaning until five weeks after breeding is a common strategy used to prevent aggression and ensure control over individual feeding during breeding, conception and implantation.   However, alternative management options are needed as pressure to reduce stall use is likely to continue. This study compared the effects of three mixing strategies on sow performance in group sow housing.Social stress from mixing sows has the potential to negatively affect sow production and welfare.
