Bien-être animal : contexte, définition, évaluation

Mormède P., Boisseau-Sowinski L., Chiron J., Diederich C., Eddison J., Guichet J.L., Le Neindre P., Meunier-Salaün M.C.

Published in 2018

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.

Multi-criteria assessment applied to animal welfare on the farm or in the abattoir: challenges and solutions from the Welfare Quality® project.

Veissier I., Botreau R., Perny P.

Published in 2010

With the development in Europe of certification programmes for livestock farms that place emphasis on respect for animal welfare, the Welfare Quality® project set out, on behalf of the European Union, to create a model for the overall assessment of animal welfare standards on farms (or abattoirs). This model is based on a multi-criteria evaluation in which 12 welfare criteria have been defined, grouped into 4 principles. An a posteriori analysis of the results shows that the model gives priority to animals in poorer condition while taking into account the average condition of the herd, and that it strongly limits compensation between criteria. This shows that this rigorous methodology is helpful to the assessment of what is a multidimensional issue, lthough it requires choices to be made concerning values that need to be made explicit and modelled.

Social ties in farmed ruminants: limits on and means of action to encourage the integration of the animal in its environment

Boissy A., Nowak R., Orgeur P., Veissier I.

Published in 2001

Farmed ruminants belong to gregarious species. Their social organisation is based on stable dominance-subordination relationships which ensure the resolution of many conflicts that are inherent in the promiscuity among animals in livestock farming. Social organisation is also based on affinity relationships that ensure group cohesion and increase tolerance between animals in situations of conflict. Furthermore, affinity relationships are closely involved in the adaptation of the animal to its living environment, since partners will influence the animal's response to its surroundings. Thus, whether through the development of behaviours that are more respectful of the animals' social needs, or by the management of periods of social transition, the adaptation and welfare of farm animals will be considerably increased.

La relation mère-jeune chez les porcins : de la naissance au sevrage

Orgeur P., Le Dividich J., Colson V., Meunier-Salaün M.C.

Published in 2002

L
Intensive pig farming imposes constraints that can be detrimental to the welfare of the pig. In wild boar or domestic pigs in semi-natural conditions, the parturient female lives in a matriarchal group and builds a nest to conceal and protect the young. A bond is established between the sow and her piglets and the suckling period lasts a minimum of 10 to 12 weeks. .... The more premature the weaning, the greater the negative impacts on behavioural and zootechnical disturbances. Proper attention to the animal's welfare calls for precautionary measures to avoid placing the animal in a situation of fear or anxiety and to enable it to express the behaviour deemed normal for the species.

Standardising the assessment of environmental enrichment and tail-docking legal requirements for finishing pigs in Europe

Hothersall B., Whistance L., Zedlacher H., Algers B., Andersson E., Bracke M., Courboulay V., Ferrari P., Leeb C., Mullan S., Nowicki J., Meunier-Salaün M.C., Schwarz T., Stadig L., Main D.

Published in 2016

This  e-learning module providing a concise summary of the scientific evidence that underpins EU legislation on pig enrichment and harvesting has been produced in seven languages, with the aim of improving consistency in professional judgements regarding legal compliance on farms. The mark profiles indicated that the roles of the participants had an impact on their scores but that the training led to overall improvement in: (i) their ability to identify enrichments which, due to their type or use by pigs, may be insufficient to ensure compliance; (ii) their knowledge of risk factors for tail biting; and (iii) their recognition of when tail docking occurs.

Risk factors and detection of lameness using infrared thermography in dairy cows- a review

Novotna I., Langova L., Havlicek Z.

Published in 2019

Lameness in dairy cows is a worldwide problem, usually a consequence of hoof diseases. Hoof problems have a negative impact on animal health and welfare as well as the economy of the farm. Prevention and early diagnosis of lameness should prevent the development of the disease and consequent high costs of animal treatment. In this review, the most common causes of both infectious and noninfectious lesions are described. Susceptibility to lesions is primarily influenced by the quality of the horn. The quality of the horn is influenced by internal and external conditions such as hygiene, nutrition, hormonal changes during calving and lactation, the animal's age or genetic predisposition. The next part of this review summarizes the basic principles and possibilities of using infrared thermography in the early detection of lameness in dairy cows.

Drinking water for liquid-fed pigs

Meunier-Salaün M.C., Chiron J. , Etore F., Fabre A., Laval A., Pol F., Prunier A., Ramonet Y., Nielsen B.

Published in 2017

Liquid feed can provide pigs with sufficient water to remain hydrated and prevent prolonged thirst. However, any lack of permanent access to fresh water prevents animals from drinking when they are thirsty. In addition, individual differences between pigs in a pen can result in the uneven distribution of water from liquid feeds, preventing some pigs from meeting their water needs. In this review, we examine the need for and provision of water for liquid-fed pigs in terms of production performance, behaviour, health and welfare. We highlight factors that may lead to water ingestion above or below requirements. Increased water requirements can be caused by several factors such as morbidity, ambient temperature or competition within the social group, underlining the need for permanent access to water, also provided for in EU legislation. Drinking animals may be the target of redirected behaviour in response to feeding restrictions or in the absence of rooting materials, thus leading to water losses. Water supply systems and the design of water troughs are essential components in ensuring easy access to water, regardless of the physiological condition of the pig, and in reducing water use, which has no benefit for the pig.

High-Fibre feeding in gestation

Meunier-Salaün M.C., Bolhuis J.

Published in 2015

Pregnant sows are generally fed in low quantities, a fact that may lead to poor satiety and may not fully satisfy their drive to express their foraging and feeding behaviours. Accordingly, feed restriction may lead to the frequent occurrence of oral activities other than feeding, including stereotypies, restlessness and aggressive behaviour in group-housed sows, which are interpreted as indicators of persistent drives and frustration associated with feeding. The inclusion of fibre in the diet reduces the latter's energy density and therefore allows meals to be larger without increasing the energy provided. In addition, dietary fibre influences the mechanisms that improve satiety and satiety at the sensory, post-digestive and post-absorption levels. This chapter examines the impact of dietary fibre on the behaviour and well-being of pregnant sows and describes its potential consequences for performance. The level of response to dietary fibre is, however, variable and depends on the characteristics of the fibre diet (inclusion rate, source of fibre, physicochemical properties), housing and feeding conditions and the characteristics of the sows, including parity, and is greater in young sows. Dietary fibre provided during gestation generally results in increased feed consumption by sows during lactation, probably due to its effects on the size and capacity of the gastrointestinal tract. Studies on the effects of fibre on reproductive performance are rare and show variable results, which could be partly attributable to an over- or underestimation of the diet's energy content during pregnancy. In conclusion, dietary fibre generally has a beneficial effect on the behaviour and welfare of pregnant sows on a restricted diet. The impact of high-fibre diets during pregnancy on reproductive performance over several successive cycles in group-housed sows merits further investigation.

Régulation des émotions chez l’animal d’élevage : focus sur les acteurs neurobiologiques

Menant O., Destrez A., Deiss V., Boissy A., Delagrange P., Calendreau L., Chaillou E.

Published in 2016

The issue of the emotions of farm animals is part of a wider drive to improve farming conditions by taking animal welfare into account. The genesis of emotions derives from the cognitive capacity of individuals to perceive, evaluate and react to their environment. …. The parts of the brain involved in the neural network for emotions are linked to the perception and processing of information from the environment, and/or in the expression of emotional responses. ... . In light of this, it is now necessary to study the effects of early experiences on the development of the neural network for emotions and to better understand the role of cognitive evaluation in the genesis of emotions.
