Obtaining accurate body weights for swine is important for calculating anesthetic drug dosages as well as an indicator used for tracking overall health. Scales used for acquiring such weights require that the pigs stand still...

To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were...

Neubauer, T., Betts, T., Evans, C. 2011. The use of enrichment to facilitate data collection in a pig study. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 762-763 (Abstract #P80).

Recently a researcher approached our large animal facility manager about housing 19, 2-mo-old piglets and assisting with data collection. Part of the protocol required that the piglets be fed an individually measured high-sugar/high-fat diet over...

Oostindjer, M., van den Brand, H., Kemp, B. et al. 2011. Effects of environmental enrichment and loose housing of lactating so

Weaning of piglets in commercial husbandry systems is earlier and more abrupt than would happen under natural conditions, resulting in low feed intakes and health and welfare problems in the immediate postweaning period. Piglets in...

Tail biting is a major problem in modern pig (Sus scrofa) production and results in a reduction of animal welfare and productive performance. Biting behaviour has been shown to be decreased by the use of...

The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain × German...

For groups of pigs to cope adequately with their housing conditions they need sufficient static space (occupied by the body of the pig), activity space (for movement between different functional areas and behaviours relating to...

Reimert, I., Bolhuis, J. E., Kemp, B. 2012. Indicators of positive and negative emotions and emotional contagion in pigs. Physiology & Behavior 109, 42-50.

For the welfare of group-housed animals, such as pigs, the emotional state of an individual pig is relevant, but also the extent to which pen mates are affected by the distress or pleasure of other...
