Effects of confinement on social interaction patterns in dry sows
Contributor(s):: Jensen, P.
Studies were carried out in 3 different herds, representing 3 different housing systems. In the first system (de-confinement), the animals were housed in groups of 5, with individual feeding stalls, a common dunging area and a common lying box (net floor area, 3.04 msuperscript 2/sow), in the...
