Early Life Painful Procedures: Long-Term Consequences and Implications for Farm Animal Welfare

Sarah J. J. Adcock

Published in 2021

A scientific review of the long-term phenotypic consequences of painful neonatal procedures in rodents, whose response to pain, fear and anxiety stimuli is initially reduced and then becomes exacerbated with age. These procedures result in cognitive, social and reproductive deficits, which can be transmitted to offspring. The implications for the long-term welfare of farm animals following early painful procedures are discussed.

Facial expressions of emotion states and their neuronal correlates in mice

Nejc Dolensek, Daniel A. Gehrlach, Alexandra S. Klein, Nadine Gogolla

Published in 2020

Preview: “The investigation of emotions is hindered by a lack of rapid and precise readouts of emotion states in model organisms. Dolensek et al. identified facial expressions as innate and sensitive reflections of the internal emotion state in mice.”

Douleurs animales. 1. Les mécanismes

Paulmier V., Faure M., Durand D., Boissy A., Cognié J., Eschalier A., Terlouw C.

Published in 2015

This article aims to bring together in a single document the knowledge acquired over recent years on the mechanisms of the appearance and modulation of pain in animals. The review is divided into three parts. The first describes the different stages of development, transmission and integration of the nociceptive messages involved in the onset of pain (sensory and emotional components). The second describes the different types of modulation that can activate or inhibit the transmission of nociceptive messages. The third describes the different neurophysiological processes that accompany pain and can modulate it (inflammation, activation of the autonomic nervous system and the neuroendocrine system).

Are animals conscious beings?  How do they perceive their own worlds? These questions are being debated in the scientific community for both academic and practical reasons. Accordingly, on 7 July 2012, a group of leading scientists in England headed by Philip Low felt it necessary to publish The Cambridge Declaration on Consciousness. This manifesto states that "a convergence of evidence indicates that non-human animals have the neuro-anatomical, neurochemical and neurophysiological substrates of conscious states as well as the ability to express intentional behaviour...". It calls for further research to learn more about this capacity in animals. In 2015, INRA carried out a multidisciplinary scientific expertise in order to provide a critical review of the literature on animal consciousness. This work was executed at the request of the European Food Safety Authority (request EFSA-Q-2015-00390, contract no. EFSA/Inra/2015/01).

This study is an overview based on the report from INRA's collective scientific expertise (Le Neindre et al., 2017). It is divided into six chapters:
––the social, ethical and legal context for the expertise (chapter 1)
––consciousness in the animal kingdom: historical perspectives, epistemology and definitions (chap. 2)
––overview of current knowledge on human consciousness, with a discussion of the main current innovative concepts given their usefulness for our understanding of the available data on animals (Chapter 3)
––behavioural and neurobiological components in animals that allow us to talk about more or less elaborate content of consciousness. This chapter constitutes the core of the expertise (chap. 4).
––the positive consequences of taking consciousness into account on our understanding of welfare, suffering and pain (chap. 5)
––the importance of consciousness in the adaptive capacities of animals, especially in their phylogenetic components (Chapter 6)
The book concludes with proposals for future avenues of research resulting from the deliberations of various scientific bodies.
