The effects of four housing treatments (neck-tethers, stalls, a group indoors and a group in a paddock), imposed at 3-5 weeks after mating, were determined on the behaviour and physiology of 24 pigs.

Pigs in tethers spent less time in active behaviours than all other treatments, and the pigs housed in stalls showed increased amounts of oral-Nasal behaviours such as manipulation of drinkers and licking/biting pen components (7% of observations) compared to all other treatments (3.1-4.8% of observations). The pigs in t..
