Li, S., Hu, H., Huang, J. et al. 2022. Effect of enrichment items on the physiology and behavior of sows in the third trimester of pregnancy. Animals 12(11), 1355.

Modern intensive pig breeding harms animal welfare, which is especially noticeable for pregnant sows kept in confinement stalls. This study aimed to evaluate the effects of enrichment items on the movement and physiological parameters of...

Zhang, J., Yu, L., Yin, G. 2022. Evaluation of behavior and affective state of different-parity sows with strong/weak pupil light reflex. Animals 12(9), 1184.

The stall-housing system is commonly used in the modern swine industry in many countries; however, long-term space restrictions can cause affective and physiological abnormalities in sows. The pupil light reflex (PLR) can reflect the psychological...

Tokareva, M., Brown, J. A., MacPhee, D. J. et al. 2022. The effect of providing a greater freedom of movement through periodic exercise on the welfare and stress physiology of stall-housed gestating sows and on piglet behaviour.

In Canada, the 2014 Code of Practice for the Care and Handling of Pigs proposed the continued operation of existing stall barns after 2024 on condition that bred sows be given access to periodic exercise...

Parois, S. P., Van Der Zande, L. E., Knol, E. F. et al. 2022. A multi-suckling system combined with an enriched housing environment during the growing period promotes resilience to various challenges in pigs. Scientific Reports 12(1), 6804.

Little is known about the impact of social and environmental enrichment on improving livestock resilience, i.e. the ability to quickly recover from perturbations. We evaluated the effect of an alternative housing system (AHS) on resilience...

Zapata Cardona, J., Ceballos, M. C., Tarazona Morales, A. M. et al. 2022. Music modulates emotional responses in growing pigs. Scientific Reports 12(1), 3382.

There is a lack of clarity on whether pigs can emotionally respond to musical stimulation and whether that response is related to music structure. Qualitative Behavioral Assessment (QBA) was used to evaluate effects of 16...

Pan, L., Nian, H., Zhang, R. et al. 2022. Stereotypic behaviors are associated with physiology and immunity differences in long-term confined sows. Physiology & Behavior 249, 113776.

Pregnant sows in the confined environment have poor welfare and frequently perform stereotypic behaviors. In order to clarify whether highly stereotypic behavior is a sign of increased stress and successfully contributes to coping with or...

Merlot, E., Meunier-Salaün, M.-C., Peuteman, B. et al. 2022. Improving maternal welfare during gestation has positive outcomes on neonatal survival and modulates offspring immune response in pigs. Physiology & Behavior 249, 113751.

Improving the housing of pregnant sows by giving them more space and access to deep straw had positive effects on their welfare, influenced their maternal behavior and improved the survival of their offspring. The present...

de Faria, C. M., Sá, F. de S., Costa, D. D. L. et al. 2022. Environmental enrichment for collared peccaries Dicotyles tajacu, Tayassuidae in managed care: Different items provoke different behavioural responses.

Being in human care often modifies the behaviour of animals, mainly because of the lack of environmental stimuli, and the ease of finding food and reproductive partners. Animals in human care may have a poorer...

Parois, S. P., Van Der Zande, L. E., Knol, E. F. et al. 2022. Effects of a multi-suckling system combined with enriched housing post-weaning on response and cognitive resilience to isolation. Frontiers in Veterinary Science 9, 868149.

Improving welfare is still a critical issue in pig husbandry. Upgrades of the housing environment seem to be a promising solution to optimise resilience as a whole, and therefore improve animal welfare. The objective of...

Kranz, V. A., Horback, K. M., Parsons, T. D. et al. 2022. Sow behavior during introduction to a large dynamic group is influenced by familiarity and method. Applied Animal Behaviour Science 250, 105624.

Sows in an extensive setting maintain small, stable matrilineal social groups comprised of familiar, and often genetically related, conspecifics. Providing conditions in an intensive farm setting which allow similar social groups could reduce aggression by...
