Atkinson, S., Algers, B., Pallisera, J. et al. 2020. Animal welfare and meat quality assessment in gas stunning during commercial slaughter of pigs using hypercapnic-hypoxia (20% CO2 2% O2) compared

This study assessed aversion, stunning effectiveness, and product quality of nitrogen and carbon dioxide (CO2) mixtures used for stunning pigs. A total of 1852 slaughter pigs divided into two similar batches was assessed during routine...

Husheer, J., Luepke, M., Dziallas, P. et al. 2021. Electrocution as an alternative euthanasia method to blunt force trauma to the head followed by exsanguination for non-viable piglets. Acta Veterinaria Scandinavica 62, 67.

On farms, the currently approved and most widely practised method of euthanising non-viable piglets is blunt force trauma to the head followed by exsanguination. However, the use of this method is criticised due to public...

Since January 2019, surgical castration of male piglets must be performed using local anaesthesia, if farmers deliver pigs to the primary exporting slaughterhouses according to the “Danish quality scheme”; a voluntary initiative taken by the...

Marcet-Rius, M., Pageat, P., Bienboire-Frosini, C. et al. 2020. The provision of toys to pigs can improve the human-animal relationship. Porcine Health Management 6, 29.

It is now widely recognised that a positive human-animal relationship is beneficial not only for farm animals’ welfare but also for productivity and the quality of products. A better understanding of animal emotions is an...

Villain, A. S., Lanthony, M., Guérin, C. et al. 2020. Manipulable object and human contact: Preference and modulation of emotional states in weaned pigs. Frontiers in Veterinary Science 7, 577433.

Enriching the life of farm animals is a legal obligation in intensive farming conditions in the European Union, though not worldwide. In pigs, manipulable materials are mandatory when no bedding is available. Like manipulable objects...

Sheil, M., Polkinghorne, A. 2020. Optimal methods of documenting analgesic efficacy in neonatal piglets undergoing castration. Animals 10(9), 1450.

Analgesic products for piglet castration are critically needed. This requires extensive animal experimentation such as to meet regulatory-required proof of efficacy. At present, there are no validated methods of assessing pain in neonatal piglets. This...

Reynolds, K., Johnson, R., Brown, J. et al. 2020. Assessing pain control efficacy of meloxicam and ketoprofen when compounded with iron dextran in nursing piglets using a navigation chute. Animals 10(7), 1237.

The efficacy of analgesics such as meloxicam and ketoprofen to control pain in piglets when mixed with iron dextran (ID) before injection is unknown. The purpose of this study was to compare perceived pain in...

Domestic animals often seek and enjoy interacting with humans. Positive human–animal relationships can elicit positive emotions and other positive welfare outcomes. Nevertheless, our understanding of the underlying processes that govern the positive perception of humans...

Navarro, E., Mainau, E., Manteca, X. 2020. Development of a facial expression scale using farrowing as a model of pain in sows. Animals 10(11), 2113.

Changes in facial expression have been shown to be a useful tool to assess pain severity in humans and animals, but facial scales have not yet been developed for all species. A facial expression scale...

Nannoni, E., Aarnink, A. J. A., Vermeer, H. M. et al. 2020. Soiling of pig pens: A review of eliminative behaviour. Animals 10(11), 2025.

This is a comprehensive review on the pigs’ normal eliminatory behaviour (i.e., defaecation and urination) and pen soiling. This review is aimed primarily at solving issues with pen soiling in current systems, and ultimately at...
