Recent developments in the European and national legislation regarding minimum standards for the keeping of laying hens will be causing changed conditions for egg production in the medium term. Enriched cages shall allow hens to better fulfill their needs than traditional battery cages. More space for the stretching of wings and legs, perches for resting, littered areas for scratching, pecking and dustbathing and nests for egg-laying behaviour shall allow layers to perform more of their normal behaviour patterns. However, regarding the sustainability of these systems there are different views and still a great lack of scientific data and practical experience. An overview is given on the development of European and national animal welfare legislation concerning laying hens, minimum requirements for enriched cages and the available evidence about animal behaviour, performance and health in these systems. Furthermore, a current project at the School of Veterinary Medicine Hannover on the animal welfare assessment of enriched cages, specifically on the Aviplus cage system, which was one of the first systems on the market and is in accordance with EU-directive, is introduced.  相似文献

The Domestic Dog lives today in the industrial nations mainly as a companion animal of man and is not so much used or exploited anymore, as in earlier times or in other cultures. There exist the following forms of keeping ("keeping systems"): Keeping in apartments or houses, keeping in enclosures or pens, keeping the dog attached or chained, letting the dog roam freely and uncontrolled. The latter form will not be discussed. For the keeping of dogs in enclosures or chained, forms which are easier to detect, observe and control, there exist rather well-defined criteria for an evaluation of the keeping conditions, to a great extent based on the animal welfare legislation. Dogs in apartments or houses however are kept in the seclusion and privacy of human homes which makes an evaluation of the keeping conditions more difficult. Basically however, the same criteria are to be applied as to the other keeping forms. Keeping of dogs in apartments or houses is to be considered as appropriate for the animal, if certain requirements are met. Dog keeping includes being busy with the animal in different ways. Animal appropriate ways of treatment of and of occupation with the dog are therefore an integrative part of correct keeping conditions.  相似文献

Before its broad application in practice, housing equipment should be tested, in particular with regard to animal welfare. The differing positions of the German Federal Council (Bundesrat) and the German Federal Parliament (Bundestag), whether such testing should be mandatory or voluntary, have been conciliated in the amended animal welfare act by empowering the Federal Ministry of Food, Agriculture and Fisheries (BML) to fix official standards for voluntary testing procedures by regulation. On request of the BML, a report as scientific basis for a draft regulation is currently prepared by the scientific animal welfare committee of the German Agricultural Society (DLG). The scientific animal welfare committee has been appointed by the DLG in order to provide support in the effort to strengthen animal welfare aspects in the DLG-utility testing procedure of housing equipment, which is in place since 1953. The committee elaborates standards concerning testing methods, assessment criteria and the necessary size of investigations. As required, the scientific animal welfare committee may support the DLG-testing bodies in the implementation of the animal welfare part of the testing procedure. It will, moreover, be involved in the welfare assessment based on the testing results. The amendments of the already established testing procedure will help to fulfill the general requirements on an acceptable animal welfare testing procedure. While keeping in mind that there are certain limits in what can be achieved by a voluntary testing procedure, the enhanced consideration of animal welfare aspects within the DLG-utility testing procedure has the advantage to be relatively unbureaucratic and in line with EU legislation, and is, therefore, an appropriate tool for a contibrution to improved animal welfare in livestock housing.  相似文献

In May 2007 a working group passed a guideline, which deals with requirements for the indoor keeping of dairy cows to perform Article 2 of the animal welfare legislation.The guideline should support the local district veterinary authorities and the stockman in the animal welfare judgement both of new and rebuilding as well as already existing stables. Whereas for new buildings minimum standards for the protection of cows are put together and beyond that additional recommendations for more "cow comfort" are given, for old buildings only standard values are presented. The guideline mentioned especially those aspects, which from previous experience always gives cause for discussion. For example: size and construction of cubicles, width and floor design of passageways or the relation between the number of animals and the number of feeding places and cubicles. All together the guideline enables the local district veterinary authorities in Lower Saxony to judge the keeping of dairy cows following equal standards.This leads to confidence in planning and investment for the livestock owners.  相似文献

In this study the animal welfare legislation and three private standards in Sweden, focusing on dairy cows, were analysed. The aim was to investigate to what extent these regulations consisted of resource-, management- or animal-based requirements, to analyse the content and discuss consequences. The results showed a higher proportion of management- and resource-based requirements than animal-based in all regulations. However, the borders between these categories were not as distinct as expected. The private standards put slightly more emphasis on the animal-based requirements and on animal welfare at herd level. It was primarily the organic standard that included higher animal welfare demands than the legislation. Due to vague wording and guideline statements it was not always clear if the welfare level achieved would be the same in practice although the requirements were similar. It will be necessary to clearly distinguish between requirements and measures to make the policy process more transparent.  相似文献

From 1 January 2007, requirements concerning animal welfare were introduced with effect to cross-compliance. Farmers receiving single payment as well as agri-environmental payments (payments of second pillar) shall respect the statutory management requirements of the following 3 directives in the area of animal welfare: Council Directive 91/629/EEC laying down minimum standards for the protection of calves; Council Directive 91/630/EEC laying down minimum standards for the protection of pigs; Council Directive 98/58/EC concerning the protection of animals kept for farming purposes. The competent authority shall carry out annual systematic inspections on at least 1% of all farmers submitting payments on the basis of a risk analysis and partly at random. In case of non-compliance with the conditions due to specific rules, there will be a reduction or cancellation of the payments to be granted in the calendar year in which non-compliance occurs. Cross-compliance controls should take place on the basis of documented procedures so as to ensure that these controls are carried out uniformly and are of a consistently high quality. For this purpose, a working group composed of representatives from the Federal Ministry of Food, Agriculture and Consumer Protection and from the Lander developed uniform control reports in order to monitor compliance and a guidance booklet for control execution of animal welfare requirements. In the control report (Level 1), the outcomes of inspections of all systematic testable animal welfare requirements are summarized in 6 items. Furthermore, the non-systematically testable requirements are integrated in the control report as a independent item. The guidance booklet (Level 2) with a matrix of validation serves as a specification for on-the-spot checks. Where appropriate, on-the-spot checks provided for cross-compliance and any other checks in animal welfare rules as well as requirements to animal identification and registration shall be carried out at the same time in Baden-Württemberg (integrated control system). Farmers subjected to on-the-spot checks shall be selected on the basis of a centralized common risk analysis and partly at random. This is the best way of safeguarding that the control rate will not be much higher than the established 1% with a minimum administrative burden and costs for farmers and competent control authorities. Integrated check lists for on-the-spot checks were established which take into account systematic cross compliance inspections to improve compliance with 3 existing standards in the area of animal welfare and official controls as proved in Council Directives concerning animal welfare and Regulation (EC) No 882/2004. All staff of the competent authorities performing controls received, for their area of competence, appropriate training enabling them to make their duties competently and to carry out controls in a consistent manner. Integrated systematic controls are very time-consuming and a burden for farmers and the competent authorities. For the beginning of this year, we will expect a discharge by Decision (EC) 2006/778. A controlling system was installed to ensure that cross compliance rules are applied consistently, for example by making subsequent controls by controlling institutions.  相似文献

Based on the law of animal welfare and on the EU-rule about keeping of wild animals in zoological gardens 15 zoological gardens in Brandenburg were inspected by a temporary team consisting of one veterinarian from the state office of feeds and agriculture, the local authorized veterinarian and one director of the zoogardens. Data of every zoological garden at first were recorded by special lists of queries. So it was possible to estimate the keeping conditions and to realize deficiencies and the main problems. During the local inspection these data were controlled and the structure of keeping units as well as the conditions and behaviour of the animals were evaluated. Every unit was evaluated taking into consideration all points of view. If necessary proposals for improvements were made which were to enforce by the local authority. Furthermore the documentation and the economic areas were inspected. The number of kept species and animals was relatively low. Only two zoological gardens were to classify as mean ones. The majority of the fences and aviaries corresponded with the minimal demands of the today rules resp. was larger in the dimension and space. There were very nice keeping units, but also some deficiently in the structure or in the quality of the ground. By some photographs positive and negative examples are demonstrated. The feeding and also the veterinary service were on high level. The team found out that staffs of the zoogardens had a positive position to animal welfare. Step by step they improved the keeping conditions. The central inspection by a multi-professional team was estimated positively and should be repeated in certain intervals. The used lists of queries were suitable. The valid rules and guide lines should be revised in near future.  相似文献

The commercial housing of African Ostriches in Germany for the breed and meat production still represents a disputed topic under the criterion of the animal's welfare. Above all critics state that the frequently wet-cold weather in Germany impairs the well-being and health of the animals. So far however there are just a few scientifically documented data about requirements for housing conditions of ostriches in Central Europe and thus hardly answers whether housing in Germany is possible under the criteria of the animal's welfare. This study tried to evaluate ostrich housing under South German climatic conditions (Rhine level), on the basis of behavioral observations of breeding ostriches. The use of the stable and the influence of different climatic parameters on the behavior were considered. In addition the behavior of 18 adult animals in 5 breeding groups from January to December 2002 was observed. Parallel various climatic data were raised. The housing of the animals took place in open stables with unrestricted pasture possibility. The ostriches reacted in their behavior to different climatic conditions. Particularly at cold weather and adverse soil conditions they used the open stable increasingly as weather protection. In addition, with increased wind velocities the animals spent more time in the stables. The daily amount of precipitation showed no influence on the frequency or duration of the stable use. Rainfall did not animate the animals to look for protection within the stable, but more to set itself on the ground in the external enclosure. The locomotion activity of the animals was strongly in dependence to the reproduction time and the territorial behavior and therefore highest in spring. On cold days the animals performed their reproduction behavior mainly in the stable. For the comfort behaviour distinct weather dependence was seen particularly for sand bathing. Warm temperatures and dry sand were the preconditions for it. Regarding the results it seems, that with the conditions existing on the examined farm, housing of ostriches under respect of animal welfare in Germany is possible. New regulations are to be demanded, adjusted to the newest level of knowledge about ostrich husbandry, with requirements for care, support, accommodation and nutrition of the animals as well as about the qualification of the owners. An occasional hobby animal husbandry limited to few single ostriches is to be rejected. Further scientific investigations at other farms, possibly also under variable climatic conditions are however necessary.  相似文献

The egg production industry is facing various problems that need to be solved. For amino acid nutrition to achieve scientific and economical feeding of laying hens, it is necessary to elucidate the content, digestibility, or availability of nutrients of feedstuffs and feeds and the requirement of amino acids for laying hens. In addition, improvement to quality of eggs and meat of spent hens, methods of management and development of new feedstuffs are essential. For sustainable animal production, decrease in excreta and animal welfare should be studied. The real‐time determination of content and digestibility of amino acids in feedstuffs are essential for formation of feeds. Recent advances in the near infrared reflectance analysis will be able to determine the content, digestibility and availability of nutrients in feedstuffs and feeds, if we have a supplemental amount of conventional analysis to define the calibration population. The amino acid requirements are affected by various factors. Therefore the method to quickly and exactly determine amino acid requirements in response to various factors is necessary. By using plasma free amino acid concentration as a criterion, it is possible to determine amino acid requirements in various conditions of laying hens within a short experimental period, repeatedly using the same animals. Because the amino acid requirements differ among individual animals, it should be expressed as grams per hen per day. Practically, it is impossible to formulate various feeds for individual hens. The various expressions have been developed and these expressions have advantages and disadvantages. The nitrogen excretion of laying hens is easily reduced by reducing dietary nitrogen levels and restricting the feed intake. The availability of amino acid may be improved by feeding management, and supplementing enzyme, but the quality of eggs and meat of spent hens and welfare of laying hens are not affected by amino acid nutrition.  相似文献

Scientific interest in farm animal welfare has grown rapidly in recent years because consumers increasingly demand that farm animals are reared, transported, and slaughtered in a humane way. Additionally, nutrition emerges as an important aspect of welfare since in most codes of recommendations for the welfare of animals, adequate nutrition is one of the primary requirements to be satisfied. We submit that in many cases domestic animals are provided with diets that, even when abundant and nutritious, are not necessarily adequate to foster the welfare of animals. The monotonous diets fed in confinement (total mixed rations) and on pasture (monocultures) often contain excesses of nutrients, nutrient imbalances, and toxins that adversely influence animal welfare. How much of any food an animal can eat will depend on the other foods it consumes, because at the biochemical level, nutrients and toxins interact one with another—nutrients with nutrients, nutrients with toxins, and toxins with toxins. Food intake and preference also depend on differences in how individual animals are built morphologically and how they function physiologically, and marked variation is common even among closely related animals relative to the needs for nutrients and tolerance to toxins. An integral part of an animal's ability to meet its particular nutritional requirements and consume substances that improve health depends on having a variety of foods available so each animal can select a diet that best meets its homeostatic needs. Food choice may also offer animals a means to cope with toxins, as certain food combinations have the potential to ameliorate the negative effects of toxins. We suggest that the availability of alternatives may not only contribute to maintain homeostasis but also reduce levels of stress. Thus, food choice is necessary for individual animals to have freedom to express their normal behaviors. We contend this freedom enables the uniqueness of individuals to be manifest, thereby promoting animal welfare and performance and increasing profitability of the people who manage animals.  相似文献

There is public discussion of the new E.U. Animal Transport Regulation No 1/2005 of Dec. 2004 and its advantages and draw-backs. This Regulation is no longer a Directive, so that it is directly applicable in the Members States. Although the Regulation is recognised to have great potential to improve welfare and health of transported animals, it will also increase administrative work. Most improvements will come through better education and the increased responsibilities of animal attendants, drivers, keepers and transport organisers, and through the stricter control mechanisms (log book, training, instructions etc.) and the introduction of the GPS control systems to further enhance the transparency of animal movements. The formats of the transport certificates used in all Member States will be harmonised. Technical records will be kept on air temperature and water consumption. Contact offices in all member states for transport affairs will improve the exchange of data between the responsible authorities and harmonise control and surveillance practice. Specific regulations are now in place for horses (broken, unbroken, registered) and for the transport age of young animals (piglets, lambs, calves, foals). In spite of some substantial improvements there are still significant gaps in our knowledge of both normal and long transports, for example optimal journey times, food and water supply on long transports, environmental factors such as vibration, motion, light and ventilation requirements in different European geographical regions. The same is true for the epidemiological aspects of the prevention of disease transmission; for example, very little is known about the bacterial and particulate emissions of the animal transport vehicles which travel across Europe. A serious drawback of the regulation is the fact that it does not abolish the unloading of animals on long transports to rest for 24 h at staging points, so that the concomitant risks to health and welfare remain, as do the opportunities for the transmission of infectious diseases at these stations. Two examples are given that demonstrate the physiological (heart rate) and biochemical (cortisol) reactions of cattle during transport. It seems useful to observe how the new Regulation affects practice and to assess the usefulness and practicability of the new rules after one or two years of operation. At the same time, more detailed research should be carried out in order to further adapt the Regulation to the needs of the animal species and gender in terms of travel time periods, food supply and resting schemes. This should also include reconsideration of loading and unloading rules in staging points on long journeys for all animals, particularly in view of risks of injury and transmission of infectious diseases. Investigations should be carried out to improve our understanding of the bio-aerosol emissions from driving and standing vehicles. Transport schemes on long journeys should be more closely adapted to the needs of the animals. The new Regulation represents another step forward toward improved animal welfare during transport in spite of some increase in the administrative measures required. It is necessary to bring together veterinary and animal science, engineering, logistics and practical and technical experience in order to improve the Regulation and the health and welfare of animals during transport.  相似文献

Abstract

Ideas within the animal welfare science arena have evolved continuously throughout the last 30 years, and will continue to do so. This paper outlines some of these developments. These included reformulation of the five freedoms concept into the five domains of potential welfare compromise. This accommodated weaknesses in the former by distinguishing between the physical/functional and the mental factors that contribute to an animal's welfare state. This development reflected a rising scientific acceptance that the mental experiences of animals were legitimate foci for study and highlighted that what the animal itself experiences represents its welfare status. Initially, most concepts of animal welfare emphasised predominantly negative subjective experiences, such as thirst, hunger and pain, and negative affective states or feelings including anxiety, fear and boredom, but today positive experiences or emotions such as satiety, vitality, reward, contentment, curiosity and playfulness are also considered to be important. During the same period, the focus shifted from evaluating the impacts of individual mental subjective experiences or emotions towards seeking a more comprehensive, multifactorial understanding. The five domains concept was specifically designed to achieve this. Subsequent notions about quality of life (QoL) had the same objective, and emphasised the importance of positive experiences. However, some approaches to QoL assessment relied heavily on empathetic speculation about what animals may experience subjectively and this raised concerns about inappropriate anthropomorphic projections. Such pitfalls may be minimised when informed personnel rigorously apply objectively based methodologies to QoL assessments limited to a short time frame. It is clear that both formal and somewhat less formal QoL assessments of this type are already used to guide decision-making about the ongoing care and therapeutic management of animals on a daily basis. However, application of the recently introduced concepts of ‘a life not worth living’, ‘a life worth avoiding’, ‘a life worth living’ and ‘a good life’ is problematical, because extending the assessment time scale to the whole of life is attended by a number of as yet unresolved difficulties. Accordingly, their value in the practical management of animals is limited so that, at present, reliance on the minimum standards and recommendations for best practice outlined in codes of practice or welfare will continue to be necessary and worthwhile. Nevertheless, these concepts have value in providing a contextual theme that strongly focuses attention on the promotion of a lifelong QoL with an overall balance that is positive.  相似文献

The role of water as an essential nutrient for the animals, their health, performance and welfare is often underestimated. Presently there exists no specific legal regulation which defines the water quality for animal consumption. Some local recommendations make reference to the German regulation for the drinking water of humans. This seems to be useful in respect to food producing animals at a first glance. However, significant practical difficulties can occur. Therefore it is necessary to include in a possible regulation for the drinking water of animals additional animal and management specific aspects such as the type of animal, the keeping system, the water supply system, the distribution systems and the drinkers which are used. It may also be useful to define animal specific thresholds for certain groups of compounds and contaminants. As a first step towards a possible regulation 12 recommendations are given to improve and standardise the water supply of farm and pet animals.  相似文献

The modern consumer is increasingly concerned about the welfare of farm animals which are kept in intensive systems on specialised farms where the health and well-being is almost completely dependent on the will, ability and care of the farmer. Further demands related to animal production are consumer health (quality and safety of food products), the protection of the environment and cheap food. The currently used husbandry systems are man made and emphasise automation which requires permanent critical observation of the welfare of the animals. Ethological indicators are equally important as health and performance to evaluate keeping systems. Future animal farming will be influenced by new technologies such as electronic animal identification and milking robots, and more important by biotechnology and genome analysis. Veterinary surgeons and farmers have to co-operate on the basis of scientifically sound animal welfare schemes which help to protect our farm animals in modern and intensive livestock production systems.  相似文献

The guidelines of the Federal Ministry of User Protection, Nutrition and Agriculture (BMVEL) regarding "horse keeping with respect to animal welfare" are from 1995 (BMELF, 1995). Therefore, they are not suitable for modern horse keeping. The Veterinary Association for Animal Welfare (TVT) held it to be necessary to rework the guide-lines in light of 1) many subsequent investigations concerning horse keeping, and 2) the species-specific needs of horses in practice. Each chapter of the BMELF (1995) guide-lines was revised such that the literature and practical experiences were updated. Several chapters (recumbency resting behaviour, fences, underground outdoor and in stables, litter) were added in the position paper of the TVT to reflect the increasing use of boxes with paddocks, loose housing systems with open yards, pasture and winter yards as housing conditions. Keeping horses outdoors permanently during winter is possible because horses have very good thermoregulatory capabilities so that they are able to adapt themselves to cold conditions. However, in light of animal welfare, the holding system must include adequate shelter (natural or artificial). Shelters should protect against wetness, heat, cold and wind, and must be sufficiently large and high, with a dry and clean underground. In keeping horses outdoors permanently, the paths to the feeding and watering areas and to the shelter must be dry. The food must also be protected against mould and soiling. Keeping horses permanently without adequate shelter or in deep marsh without any dry places is against the Animal Protection Act.  相似文献

The purpose of the study was to investigate the influence of demographic and experiential factors on first-year veterinary students career choices and attitudes to animal welfare/rights. The study surveyed 329 first-year veterinary students to determine the influence of demographic factors, farm experience, and developmental exposure to different categories of animals on their career preferences and on their attitudes to specific areas of animal welfare and/or rights. A significant male gender bias toward food-animal practice was found, and prior experience with particular types of animals--companion animals, equines, food animals--tended to predict career preferences. Female veterinary students displayed greater concern for possible instances of animal suffering than males, and prior experience with different animals, as well as rural background and farm experience, were also associated with attitude differences. Seventy-two percent of students also reported that their interactions with animals (especially pets) had strongly influenced the development of their values. Animals ranked second in importance after parents in this respect. The present findings illustrate the importance to issues of animal welfare of the cultural context of past experience and influences on attitude development. The results also suggest that previous interactions with animals play a critical role in guiding veterinary students into their chosen career, as well as in helping to determine their specific employment preferences within the veterinary profession. From an animal welfare perspective, the dearth of women choosing careers in food-animal practice is a source of concern.  相似文献

Recently, eel recirculation systems have provoked increasing attention in intensive fish culture, especially concerning animal welfare. "Aquaculture", "Intensive Culture", and "Recirculation Systems" are often confused with each other. This study, first of all, differentiates among these terms. The economic relevance of aquaculture in the Federal Republic of Germany is demonstrated by figures. A tendency towards intensive methods can only be seen in trout and eel culture. The problems of recirculation systems are explained comprehensively. Particular emphasis is laid on the conflict between theoretical suitability of intensive fish production and the absence of commercially working systems. At present, intensive fish culture does not pose a serious animal welfare problem in Germany. However, it is necessary to define the biological requirements of fish concerning their optimal accommodation in aquaculture facilities. According to the Law for the Protection of Animals, these requirements have to be laid down in an ordinance. Only then control is possible as to whether aquaculture systems fulfill fish welfare demands.  相似文献

The objective of this review is to consider the ethics of stockmanship, particularly from the perspective of the nature and extent of the duties of stockpeople to their farm animals. It will consider what science tells us about the impact of stockmanship on the animal, particularly the welfare of the farm animal. The effects of human-animal interactions on the stockperson will also be considered, since these interactions affect the work performance and job satisfaction of the stockperson and thus indirectly affect animal welfare. Animal ethics is broader than animal welfare and includes economic as well as philosophical, social, cultural and religious aspects. This paper is predicated on the view that farm animals can suffer, and that animal suffering is a key consideration in our moral obligations to animals. Housing and husbandry practices affect farm animal welfare and thus farmers and stockpeople have a responsibility to provide, at minimum, community-acceptable animal housing and husbandry standards for their animals. The farmer's or stockperson's attitudes and behaviour can directly affect the animal's welfare and thus they also have a responsibility to provide specific standards of stockmanship for these animals. However, research suggests that the behaviour of some stockpeople is not as correct as it might be. Such situations exemplify the inevitably unequal human - domestic animal relationship, and this inequality should be considered in analysing the boundary between right and wrong behaviour of humans. Thus ethical discussion, using science and other considerations and involving stockpeople, livestock industries, government and the general public, should be used to establish and assure acceptable stockperson competencies across the livestock industries. Training programs targeting the key attitudes and behaviour of stockpeople presently offer the livestock industries good opportunities to improve human-animal interactions.  相似文献

As far as the small animals are concerned, animal husbandry refers to animal welfare and management. There are five main areas of undergraduate instruction in this subject--normal animal behaviour, nutritional requirements, restraint, housing and management in disease. University education, vacational studies and personal experience all provide important sources of knowledge. Most university instruction in small animal welfare and management is provided in the clinical courses where extensive care material can be utilised in practical teaching. Integration of the animal husbandry and clinical courses is to be encouraged.  相似文献
