This concept note puts the issue of welfare back into its context, proposes a definition that takes account of the latest knowledge on the sensitivity and consciousness of animals, and considers their practical incorporation into animal husbandry. The importance of the welfare of animals dependent on humans (farm animals, pets, zoo animals, circus animals, laboratory animals, etc) has gradually asserted itself over the last 50 years, particularly in the context of animal production, and is at the heart of concerns over the future of animal husbandry. The concept of animal welfare is placed in its philosophical, societal and legal contexts, all of which influence the ways it is taken account of and the meanings assigned to it. Particular attention has been paid to the scientific foundations for the concept of welfare, based on the psychological characteristics of animals as sentient and conscious beings. ... Protocols for assessing animal welfare must therefore combine the analysis of behaviour and the physiological and health status of the animal with data on the environment.

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).

In order to achieve the objective evaluation of emotions in farm animals, the Agri-Bien-Être Animal network (an interdisciplinary group created by INRA in 1998, www6.inra.fr/agri_bien_etre_animal) has proposed experimental strategies based on cognitive evaluation theory in human psychology (Boissy et al 2007, Box 1). According to this conceptual framework, emotions are generated by the cognitive evaluation of a situation confronting the animal. Although the characterisation of these situations is complex (Forkman et al 2007), it is suggested that the animal would evaluate them using basic criteria for relevance (suddenness, novelty, etc) and involvement (predictability, etc), the degree to which they correspond to expectations, and according to its own adaptive capacities (controllability of the situation). At the end of this evaluation phase, the emotion felt by the animal is translated into emotional expression. It is the latter that can be assessed by the objective measurement of behavioural and physiological emotional responses (Box 2). By applying this conceptual framework to research in the neurobiology of emotions, the representation of the neural circuit of emotions can be built around those structures involved in the perception of the environment, information processing and the expression of emotional responses (Figure 1). From an experimental point of view, this theoretical framework requires the characterisation and standardisation of situations likely to serve as a trigger and the characterisation of the emotional responses expressed by individual animals in relation to the neurobiological actors studied.

It is now widely accepted that social welfare is not simply the absence of negative experiences, but rather the presence of positive experiences such as enjoyment. However, scientific research on positive emotions has long been neglected. This paper addresses two main issues: first, it reviews the current state of scientific knowledge supporting the existence of positive emotional states in animals and, second, it suggests possible applications of this knowledge to improve quality of life under animal management conditions. In the first part of the paper, we review recent advances in psychology and neuroscience to provide pragmatic frames based on cognitive processes (such as positive anticipation, contrast and controllability) for use in further investigation of positive emotions in animals. Next, the neurobiological basis of positive emotions is brought to animal welfarer in the identification behavioural and physiological expressions of positive experiences in animals. The monitoring of the autonomic nervous system (via the heart rate and its variability) and the immune system could provide appropriate tools to better assess emotional states in animals, supplementing classic adrenal cortical measurements. In the second part of the paper, useful strategies to enhance positive experiences (such as physical, social and cognitive enrichment or putative genetic selection) are described. The paper then turns to practical applications to assess and promote positive emotions that can help improve an animal's quality of life. Play, affiliation behaviours and certain vocalisations would appear to be the most promising indicators to evaluate positive experiences in laboratory animals and in farm animals kept under commercial production conditions.

Fear is probably the most-studied emotion in pets. In this overview, we attempt to establish the levels of repeatability and validity for fear tests carried out on cattle, pigs, sheep and goats, poultry and horses. We focus our review on the three most common types of fear tests: the arena test (open field), the novel object test and the stress test. For some tests, e.g. tonic immobility in poultry, there is a good body of literature on the factors affecting test results, test validity and age dependency. However, there are relatively few such well-defined and validated tests, and the element that is particularly lacking for most tests is information on robustness, i.e. what aspects can be modified without affecting the validity of the tests. The relative lack of standardised tests is an obstacle to the development of applied ethology as a science.

Farm management has changed radically in developed countries over the last five decades. Many of these changes are the result of intensification, which leads to farming conditions that are far removed from the natural conditions in which animals can freely express their natural behaviours. For example, laying hens in cages cannot scratch the ground or flap their wings, pregnant sows in individual gestation stalls are unable to prepare a nest for their future litters, and dairy cows are unable to suckle their calves. These changes do not appear to have had a negative effect on animal productivity, but they have raised deeper questions about the moral justification for keeping animals in such conditions. In developing countries, many societies, such as pastoralist peoples, have a long tradition and sophisticated knowledge of animals and animal husbandry. Indeed, the welfare and health of the herder and his family depend on the welfare and health of their animals. Recently, Western practices have spread to developing countries and people with no traditional connection to the keeping of livestock are beginning to work in this sector, particularly in intensive systems. This book is intended to meet the needs of both pastoralists who are the heirs to local traditions and small-scale farmers and businessmen interested in more intensive or Western-type peri-urban management systems. It will also be useful to those involved in rural development and to non-governmental organisations and agricultural advisory services. The book brings together information on the behaviour and welfare of production animals that is likely to be of use in tropical climates and is usually hard to find, being widely dispersed across the scientific literature.

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.
