Lencioni, G. C., de Sousa, R. V., de Souza Sardinha, E. J. et al. 2021. Pain assessment in horses using automatic facial expression recognition through deep learning-based modeling. PLOS ONE 16(10), e0258672.

The aim of this study was to develop and evaluate a machine vision algorithm to assess the pain level in horses, using an automatic computational classifier based on the Horse Grimace Scale (HGS) and trained...

Lourenço da Silva, M. I., Almeida Paz, I., Chaves, G. et al. 2021. Behaviour and animal welfare indicators of broiler chickens housed in an enriched environment. PLOS ONE 16(9), e0256963.

The present study aimed to assess the influence of adding straw bales, step platforms, and laser projectors as environmental enrichment resources on the behaviour and welfare indicators of broiler chickens (Gallus gallus domesticus). A sample...

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...

Toinon, C., Waiblinger, S., Rault, J.-L. 2021. Maternal deprivation affects goat kids’ stress coping behaviour. Physiology & Behavior 239, 113494.

Maternal deprivation early in life has been shown to disrupt neonates’ development. Nevertheless, separating the young animals from their dams soon after birth remains a common practice in dairy farm husbandry. This study investigated the...

Tresler, A., Rasbach, C., Stevens, T. et al. 2021. Adapting positive reinforcement training to novel laboratory species. Laboratory Animal Science Professional 9(6) (November/December), 42-44.

Positive reinforcement training (PRT) is a component of a comprehensive species-appropriate enrichment program to train specific species behaviors and reduce the stress on animals. Our facility has historically used PRT with nonhuman primates, so we...

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...

Schoiswohl, J., Stanitznig, A., Sigmund, M. et al. 2021. Comparison of alternative disbudding methods with hot-iron dehorning of goat kids. Journal of Veterinary Behavior 46, 31-39.

Goat kids are frequently disbudded in intensively farmed units to reduce the number of accidental injuries to other animals and farm workers due to horn growth. The most commonly used method is thermal disbudding which...

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...

Jones, N. A. R., Webster, M. M., Salvanes, A. G. V. 2021. Physical enrichment research for captive fish: Time to focus on the DETAILS. Journal of Fish Biology 99(3), 704-725.

Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted the many...

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...
