Abstract:
The assessment of animal welfare on-farm is important to ensure that current welfare standards are followed. The current manual assessment proposed by Welfare Quality® (WQ), although being an essential tool, is only a point-estimate in time, is very time consuming to perform, only evaluates a subset of the animals, and is performed by the subjective human. Automation of the assessment through information technologies (ITs) could provide a continuous objective assessment in real-time on all animals. The aim of the current systematic review was to identify ITs developed for welfare monitoring wi

Abstract:
The competent authorities of the Member States of the European Union are required to perform animal welfare inspections on livestock farms. The data obtained from these official inspections performed in Finnish cattle and pig farms in 2010–2015 were used with the aim of estimating the prevalence of the most common non-compliances and identifying underlying risk factors. The prevalence of non-compliant cattle and pig farms was 24.2% and 27.9%, respectively. In cattle, the most common problem was an inadequate lying area followed by deficient housing conditions for calves; in pigs, it was a lack

Abstract:
Hunting feral pigs using dogs is a popular recreational activity in Australia. Dogs are used to flush, chase, bail, and hold feral pigs, and their use for these activities is legal in some states and territories and illegal in others. However, there is little knowledge about the health and welfare of dogs owned specifically for the purpose of pig hunting. We conducted a review of the literature on working dogs in Australia and overseas to determine the likely welfare impacts confronting pig-hunting dogs. We identified numerous challenges facing pig-hunting dogs throughout their lives. Risks to

Abstract:
Livestock industries such as the pork industry are striving to continuously improve the welfare of animals. Inherent to the success of this is the ability to rigorously assess the welfare of animals in the field. While much progress has been made towards the development of methodology to assess the welfare of animals, there have been major challenges to establishing practical and definitive procedures to assess the welfare of animals. These include, but are not limited to, establishing a universally accepted definition of animal welfare and the choice of measures that are taken from the animal

Abstract:
The assessment of swine welfare requires feasible, reliable, and reasonable indicators. On-farm evaluation of pig welfare can provide valuable information to veterinarians and farmers. However, such protocols can result expensive and time-consuming. With this regard, an interest in the appraisal of swine welfare at abattoir has grown over the recent years. In particular, the use of certain lesions collected directly from slaughtered animals to determine the welfare status of pigs has been evaluated by several authors. In the present review, the different methods developed to score lesions coll

Abstract:
In recent years, there have been very dynamic changes in both pork production and pig breeding technology around the world. The general trend of increasing the efficiency of pig production, with reduced employment, requires optimisation and a comprehensive approach to herd management. One of the most important elements on the way to achieving this goal is to maintain animal welfare and health. The health of the pigs on the farm is also a key aspect in production economics. The need to maintain a high health status of pig herds by eliminating the frequency of different disease units and reducin

Abstract:
A common method of housing newly weaned pigs from outdoor systems involves very large groups in straw-bedded pens. Concerns regarding pig welfare on these systems have been expressed in relation to excessive group size, the risk of hypothermia (no supplementary heating), disease challenge and the competition to which smaller piglets are subjected. Accordingly, indices of welfare (health, mortality, behaviour, growth rate and feed efficiency) were monitored in 2 large groups of newly weaned pigs.

Abstract:
Animal welfare is not only an ethically important consideration in good animal husbandry but can also have a significant effect on an animal’s productivity. The aim of this paper was to show that a reduction in animal welfare, in the form of increased stress, can be identified in pigs from frontal images of the animals. We trained a convolutional neural network (CNN) using a leave-one-out design and showed that it is able to discriminate between stressed and unstressed pigs with an accuracy of >90% in unseen animals.

Abstract:
Pig production is the most important animal production sector in the EU, and the tail biting is still one of the most important problems of welfare and health. This behavioral disorder causes large economic losses through the medical costs for injured animals, prolonged rearing time, mortality, discarding of carcasses (or parts of carcasses) due to abscesses and finally due to potential transfer of other diseases. Abscesses, which develops because of tail biting besides economic risk, can also present a public health risk for consumers. In order to reduce potential risks, pig breeders still ro

This research project addressed pain at parturition in pigs using three different approaches. Firstly, a survey study explored UK pig farmer and veterinarian attitudes to pain and the use of pain relief in order to understand the commercial context behind decisions relating to pain and its management. Secondly, an observational study was conducted to investigate the use of behaviour to assess pain associated with the process of giving birth (or farrowing) in pigs. A final experimental study was used to investigate the administration of a pain relief drug post-farrowing to improve pig welfare a

En parallèle, être capable de mesurer l’apparition d’émotions négatives reste aussi essentiel, car, en définitive, il serait envisageable de considérer que le bien-être animal positif devrait inclure l’émission fréquente d’émotions positives associée

Abstract:
If the aim of a welfare assessment is to describe the welfare on-farm, not only here and now but for a longer time period, then the measures to be used have to be chosen with this in mind. It is by choosing relevant but common indicators that the assessment is representative of the farm over time. There are two types of animal welfare protocols, those that require the farms to comply with a set of criteria and those that attempt to assess the welfare of the animals on the farm. The advantage of the first approach is that it is transparent and easy to understand, the advantage of the second that it is more flexible and can give a better understanding of what is happening on the farm.

Abstract:
This chapter reviews assessing emotions in pigs, specifically focusing on the ways of determining negative and positive mental states. It begins by examining behavioural indicators of emotion such as behavioural tests, qualitative behaviour assessment, vocalisations, play behaviour, defence cascade responses and facial expression and body posture. The chapter also assesses cognitive indicators of emotion in pigs and judgement bias. This is followed by a discussion of neurophysiological indicators of emotion in pigs, focusing specifically on the physiology of negative and positive emotions.
