Can a Digital Application for Animal Welfare Self-Assessments by Farmers Help Improve the Welfare of Free-Range and Organic Pigs?

As part of the European Green Deal, the EU has recognised that there is a need to increase organic farming as well as improve animal welfare standards. The PIGLOW app was developed with these goals in mind and allows free-range and organic pig farmers to perform welfare assessments (WAs) of their pigs. The results of each WA contain automated feedback and benchmarking information.

Similar behavioral but different endocrine responses to conspecific interactions in hand-raised wolves and dogs.

Domestication has altered dogs' conspecific social organization compared to their closest, non-domesticated relatives, gray wolves. Wolves live in packs whose survival depends on coordinated behavior, but dogs rely less on conspecifics, which predicts greater cohesiveness in wolf than dog packs. Endocrine correlates such as oxytocin and glucocorticoids modulate group cohesion resulting in species-specific differences in social interactions.

Complex Housing, but Not Maternal Deprivation Affects Motivation to Liberate a Trapped Cage-Mate in an Operant Rat Task.

Early life environment influences the development of various aspects of social behavior, particularly during sensitive developmental periods. We studied how challenges in the early postnatal period or (early) adolescence affect pro-social behavior. To this end, we designed a lever-operated liberation task, to be able to measure motivation to liberate a trapped conspecific (by progressively increasing required lever pressing for door-opening).
