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. Typically, the period from the decision to cull and until a sow is slaughtered consists of a stay in an on-farm pick-up pen (hours to weeks), transport (eventually passing buying stations or similar) and lairage. However,...
