Misra, S., Bokkers, E., Upton, J. et al. 2021. Effect of environmental enrichment and group size on the water use and waste in grower-finisher pigs. Scientific Reports 11(1), 16380.

The grower-finisher stage accounts for 64% of the total on-farm herd water use. Part of this is consumed by the pigs, but a part is also wasted. Drinking water usage and wastage is affected by...

Fels, M., Schrey, L., Rauterberg, S. et al. 2021. Early socialisation in group lactation system reduces post-weaning aggression in piglets. Veterinary Record 189(12), e830.

Background: Pre-weaning group housing for sows and their litters is expected to enhance animal welfare. However, knowledge of potential benefits of pre-weaning socialisation for piglets after weaning is still lacking. Methods: Weaner pigs were mixed...

D'Eath, R. B., Foister, S., Jack, M. et al. 2021. Changes in tail posture detected by a 3D machine vision system are associated with injury from damaging behaviours and ill health on commercial pig farms. PLOS ONE 16(10), e0258895.

To establish whether pig tail posture is affected by injuries and ill health, a machine vision system using 3D cameras to measure tail angle was used. Camera data from 1692 pigs in 41 production batches...

Watai, Y., Uchihashi, M. 2021. Group housing procedure of laboratory farm pigs. Laboratory Animal Science Professional 9(5) (September/October), 58-60.

Our initial attempt was to individually place pigs in cages according to the serial numbers assigned by the vendor and remove cage inserts to combine those that happened to be next to each other. Unfortunately...

Merley, A. L., Duke Boynton, F. D. 2021. Design and construction of a low-cost mirror for enrichment of socially isolated pigs. Laboratory Animal Science Professional 9(5) (September/October), 56-57.

Due to their social needs, every effort should be made to house pigs with compatible conspecifics; however, there may be instances where due to experimental or veterinary concerns, single housing is necessary. In those situations...

Kinaci, A., Vaessen, K., Redegeld, S. et al. 2021. Minimizing complications in a porcine survival craniotomy model. Laboratory Animals 55(5), 435-442.

A large craniotomy survival porcine model is useful for scientific research. The surgical approaches and complications of craniotomies in pigs have not been published before. This study describes how large craniotomies were performed in 46...

Vinícius dos Santos, J., de Souza Farias, S., Pereira, T. L. et al. 2021. Preference for and maintenance of interest in suspended enrichment toys in confined growing pigs. Journal of Veterinary Behavior 45, 68-73.

The objective of the present study was to evaluate the preference for, interest in, and behavior of growing pigs provided with three different suspended enrichment toys in a four-compartment environmental preference chamber (EPC). Sixty pigs...

Krugmann, K. L., Mieloch, F. J., Krieter, J. 2021. Can tail and ear postures be suitable to capture the affective state of growing pigs? Journal of Applied Animal Welfare Science 24(4), 411-423.

The present study examined whether tail and ear postures in fattening pigs (n = 228) housed in different environments could be suitable for assessing their affective state. In doing so, it investigated the appearance of...
