Abreuvement des porcs dans le cadre du bien-être animal

ANSES

Published in 2016

The report addresses the watering of pigs, focusing on those with a soup feeding system and taking into account the different stages of rearing (post-weaning and fattening piglets, pregnant and lactating sows, etc). The experts stressed the importance of the economic issue with regard to the watering of pigs on the farm, but this economic analysis was outside the scope of the expertise. The expertise focused on the production of liquid manure in pig farming in connection with watering systems, but without analyzing the environmental side of its management. The supply of sufficient quantities of water is essential for the maintenance of homeostasis and the survival of the individual. Only permanent access to drinking water allows the physiological needs of pigs to be met flexibly and individually at all times. It also enables the animal to cope with risky situations, for example, when it is hot or when it is suffering from disorders (illness, intoxication, behaviour, etc.). Moreover, permanent access to water can contribute to a state of satiation when the animal is subjected to food rationing. Permanent access to water, together with regular checks on the quantities taken, can be a warning and prevention sign of the appearance of health and welfare problems. In the case of liquid feed without the presence of a supplementary drinking trough, most of the water needs are covered for most animals. However, this type of feed does not allow permanent access to water and therefore does not allow animals to drink systematically as soon as they are thirsty. Water can be provided in the trough, but it must guarantee the permanent presence of drinking water. To ensure adequate watering with troughs, it is necessary to ensure that their design, positioning and operation guarantee optimal access regardless of the physiological stage of the animals. In the absence of manipulable materials in the pens, the drinking trough may be the target of redirected behaviour, linked to frustrated investigative behaviour (cf. Anses opinion 2013-SA-018020). Such use diverts the function of the water trough as a drinking system and may result in restricted access to water for some pigs despite a permanent supply. The introduction of water troughs in soup feeding systems may lead to an increase in the amount of water in the manure produced. However, solutions to this problem include reducing the dilution rate of the soup where technically feasible in the farm (e.g. reducing "wastage" by optimising the design and flow rate of drinkers, covering slurry pits, etc.). The experts also recommend promoting the acquisition of technical references (water flows, number of pigs per trough...) on complementary watering. At the same time, an awareness programme for farmers should be developed on the importance of watering in terms of animal health and welfare. This programme should be accompanied by technical recommendations and accompanying measures to facilitate the introduction of watering systems.

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.

Enrichissement du milieu d’élevage des porcs par la mise à disposition des matériaux manipulables

ANSES

Published in 2015

This Opinion focuses on the value of manipulable materials, whose presence offers an effective means of enriching the living environment of pigs reared on slatted floors. They encourage the expression of investigative and manipulating behaviours but also, depending on the nature of the added materials, of maternal and foraging behaviours. They preclude behavioural frustration and induce positive emotions that can reduce deviant behaviours such as cannibalism and stereotyping and can limit negative emotions. Used properly, manipulable materials can have a positive impact on animal welfare. However, this impact is variable and can be negative, depending on the physical characteristics and distribution patterns of the manipulable materials. The impact is also negative when the manipulable materials introduce health risks. Before any routine use, the effect of the materials on welfare should be tested on the animal. In light of the prevalence of slatted floors on French livestock farms, it is desirable to make best use of such materials in ways that are worth developing further, under conditions that are adapted to the animal's welfare. Work on manipulable materials has been carried out very widely and has made it possible to identify the intrinsic qualities that retain the animals' interest and encourage investigation and manipulation. However, further work is still needed on animals' motives in using manipulable materials, on the latters' effectiveness, on methods of introduction and presentation,  on an economic evaluation of their distribution, on the development of new materials, on the health risks associated with their characteristics, on their effects on brain function, on the acceptability of their use by breeders and on the contribution of their use to the public's perception of livestock farming.

Welfare Quality® assessment protocol for cattle

Christoph Winckler, Bo Algers, Kees van Reenen, Hélène Leruste, Isabelle Veissier, Linda Keeling, Andy Butterworth, Gwen van Overbeke, Vere Bedaux

Published in 2009

Welfare Quality® combines analysis of consumer perceptions and attitudes with current knowledge from animal welfare science. This has led to the identification of 12 criteria that must be properly taken into account by evaluation systems. To address these issues, it has been decided to focus on those indicators classified as animal-based, which address aspects of the immediate welfare status of animals, such as their behaviour, fear, health or physical condition. These animal-based measures include the effects of variations in farm system management (role of the farmer) as well as particular system-animal interactions. It is however clear that resource-based and management-based measures can also contribute to a welfare assessment if they are closely correlated with animal-based measures. In addition, resource- and management-based measures can be used to identify animal welfare risks and to identify the causes of poor welfare so that improvement strategies can be implemented.
This protocol describes the procedures and requirements for the assessment of the welfare of cattle and is limited to the main categories of production animals, i.e. feeder cattle, dairy cows and veal calves. The document first outlines the on-farm collection of measurement data on feeder cattle, followed by the procedures for calculating scores. The next section describes the collection of data at the abattoir to assess the welfare of feeder cattle at the time of slaughter. Next, the procedure for on-farm collection of measurement data on dairy cows and the calculation of scores for overall farm welfare assessment is described, followed by the protocols for on-farm collection of the same data from calves, along with a description of data collection protocols for measurements taken at the abattoir but relevant to farm welfare. These last two sections complement each other and are used together to calculate on-farm welfare scores for veal calves.

AWIN Welfare assessment protocol for sheep

Cathy Dwyer, Roberto Ruiz, Ina Beltran de Heredia

Published in 2015

The European AWIN project has developed welfare assessment protocols that provide a range of reliable, feasible and practical animal-based indicators for the evaluation of animal welfare in order to promote the improvement of animal production systems across Europe. The protocols have been developed for species with very different husbandry systems, ranging from highly intensive to pasture-based systems, and involving different production parameters, from intensive dairy production to extensive meat or draught animal production.
This particular welfare assessment protocol is intended for adult female sheep (over one year of age), kept for milk and/or meat and has been tested for this specification. The protocol has not been tested for ewes kept primarily for wool production, or for dual-purpose meat and wool production, but it is expected that the protocol may also be applicable  for such cases. The protocol applies and has been tested on adult ewes kept indoors and outdoors. Since the indicators are based on sheep biology, many of the indicators may also be relevant to adult male sheep, but the protocol has not yet been tested for use in male animals.

AWIN Welfare assessment protocol for goats

Monica Battini, Silvana Mattielo, George Stiwell, Ana Viera

Published in 2015

The European AWIN project has developed welfare assessment protocols that provide a range of reliable, feasible and practical animal-based indicators for evaluating animal welfare in order to promote the improvement of animal production systems across Europe. The protocols have been developed for species kept under very different husbandry systems, ranging from highly intensive to pasture-based systems, and that involve different production parameters, from intensive dairy production to extensive meat or draught animal production.

This welfare assessment protocol is intended for dairy goats kept in intensive or semi-intensive production systems. Many of the indicators developed here are applicable to other categories of goats (non-producing goats, kids...), but have not been validated for these categories.

Douleurs animales. 2. Evaluation et traitement de la douleur chez les ruminants

Faure M., Paulmier V., De Boyer Des Roches A., Boissy A., Terlouw E.M.C., Guattéo R., Cognié J., Courteix C., Durand D., 2015

Published in 2015

The establishment of efficient and simple tools to detect pain and assess its intensity would make it possible to meet the needs of professionals (farmers and producers, veterinarians, researchers, etc.), to answer questions raised by public opinion and debate on animal pain and to meet the requirements of the regulations on the use of animals for scientific purposes (cf. Coetzee 2013, bibliographical review). Recent studies have already enabled the identification of behavioural, zootechnical and physiological indicators for the presence and even the intensity of pain (cf. review of the literature by Prunier et al 2013). However, no integrated approach involving the simultaneous use of all these indicators has been developed to date. Moreover, some indicators cannot be used in current practice, and the sensitivity (Se) and specificity (Sp) of the various potential indicators are not always optimal. One route is to combine the indicators in order to increase their informational value. Through this overview, we wish to show i) that evaluation of type and level of pain is essential for optimal pain management and ii) that an evaluation based on a multiparametric approach is best suited to such an objective.

Assessment of positive emotions in animals to improve their welfare

Boissy A., Manteuffel G., Jensen M.B., Moe R.O., Spruijt B., Keeling L., Winckler C., Forkman B., Dimitrov I., Langbein J., Bakken M., Veissier I., Aubert A.

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.

A critical review of fear tests used on cattle, pigs, sheep, poultry and horses

Forkman B., Boissy A., Meunier-Salaün M-C., Canali E., Jones R.B.

Published in 2007

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.
