Did European pig-welfare legislation reduce pig welfare? Perhaps not, but experts confirm that common indestructible materials are not proper enrichment for pigs at all, except perhaps for an enhanced novel branched-chains design.

EC Directive 2001/93 requires that all pigs have access to proper investigation and manipulation materials. Intensively farmed pigs in Europe are frequently provided with a short/bare metal chain with or without an indestructible object attached to the chain. To date authorities are regarding this as proper enrichment. However, it has become increasingly clear that the chains do not provide proper enrichment, and that adding an indestructible object such as a ball, pipe or hard wood to the end of the chain may even reduce pig welfare. To test this hypothesis an expert survey was conducted. In total 36 international experts, mostly pig-welfare scientists, responded to the survey.

The experts only marginally agreed with the hypothesis (agreement score 4.6 on average on a scale from 0-10). However, indestructible materials generally received very low scores for welfare, indicating they did not provide proper enrichment. Ranked from low to high average welfare score, the objects were grouped in 5 significance levels:

Level 5 (totally insufficient): Chain hanging too high (for most of the smallest pigs in the pen; average score 1.3 on a scale from 0 to 10 where 5.5 would be ‘acceptable’)

Level 4 (extremely insufficient): Short chain (3.1), Small ball (2.8) and Big ball (average 2.5)

Level 3: (very insufficient) Pipe (3.5) and Bare chain (3.3)

Level 2-3 (very/rather insufficient): Hard wood (3.7)

Level 2 (rather insufficient): Chain on the floor (average: 4.4)

Level 1 (almost sufficient): Branched chains (5.1)

Compared to the marginal enrichment provided before the EC Directive 2001/93 was implemented in 2007 (in the Netherlands generally a short/bare chain, scoring 3.1 and 3.3 respectively, i.e. Level 3-4), adding balls or pipe , as commonly done in The Netherlands and Germany, does not improve pig welfare. Hard wood, as practised esp. in the UK, is a most marginal improvement (only 0.4 higher on average than Bare chain). Chain on the floor scored a bit better (4.4), without being acceptable (set at 5.5). The ‘new’ Branched chains scored significantly better than all other indestructible materials and its welfare score (5.1 on average) was close to the pre-defined level of acceptability (5.5 on a scale from 0, worst, to 10, best). The welfare benefits of adding balls, pipes or hard wood to the metal chain were marginal, and well below what the experts considered acceptable enrichment. The branched-chains design, by contrast, appears to be the most viable alternative. It involves providing a longer chain, i.e. with the free end reaching to floor level, adding ‘branches’, i.e. several short chains ending at the nose height of the pigs, and providing more chains per pen (i.e. 1 branched chain per 5 pigs). Therefore, the implementation of current pig-enrichment legislation needs revision. Branched chains should be implemented widely (across the globe) and in the short term as a first step towards, and benchmark for, providing proper enrichment to intensively-farmed pigs.

Abstract

EC Directive 2001/93 requires that all pigs have access to proper investigation and manipulation materials. Intensively farmed pigs in Europe are frequently provided with a short metal chain with or without an indestructible object attached to the chain. To date authorities are regarding this as proper enrichment, perhaps with (in)direct reference to the RICHPIG model as a justification. However, it has become increasingly clear that the chains do not provide proper enrichment, and that adding an indestructible object to the end of the chain may even reduce rather than improve pig welfare. To test this hypothesis an expert survey was conducted containing 26 more or less compound questions. On a scale from 0 to 10 experts specified their level of agreement with the hypothesis, the prevalence and welfare scores of nine indestructible enrichment materials. In total 36 experts, mostly pig-welfare scientists, responded (response rate: 39%). Indestructible objects are less prevalent in countries that provide straw (like Sweden and the UK) and outside the EU (US). They are more prevalent in the Netherlands, Belgium, France and Finland, while the prevalence seems to be low in Spain. Balls, wood and pipes were provided most frequently: hard wood especially in the UK (as specified in farm assurance); indestructible balls and pipes in Germany and the Netherlands. The experts’ score for agreement with the hypothesis was only 4.6 on average (scale 0-10; n=25). Enrichment materials, ranked from high to low welfare score, were grouped in 5 significance levels as indicated by different superscripts based on Wilcoxon signed rank tests: Branched chains (5.1a), Chain on the floor (4.4b), Hard wood (3.7bc), Pipe (3.5c), Bare chain (3.3c), Short chain (3.1d), Small ball (2.8d), Big ball (2.5d), and Chain hanging too high (1.3e). Branched chains scored significantly better than all other indestructible materials and its welfare score (5.1 on average) was close to the pre-defined level of acceptability (5.5 on a scale from 0, worst, to 10, best). The welfare benefits of adding balls, pipes or hard wood to the metal chain were marginal, and well below what the experts considered acceptable enrichment. The branched-chains design, by contrast, appears to be the most viable alternative. It involves providing a longer chain, i.e. with the free end reaching to floor level, adding ‘branches’, i.e. several short chains ending at the nose height of the pigs, and providing more chains per pen (i.e. 1 branched chain per 5 pigs). Branched chains should be implemented widely and in the short term as a first step towards, and benchmark for, providing proper enrichment to intensively-farmed pigs.

Proper enrichment for intensively-farmed pigs – From review to preview

Bracke, M.B.M. 2016. Enrichment materials for intensively-farmed pigs – From review to preview (Conference abstract & presentation, ICPD 2016). In: Kemp, B. et al., 2016. 16th International Conference on Production Diseases in Farm Animals. June 20-23, 2016. Wageningen, NL. p. 179.

Abstract

Tail biting is a well-known production disease in intensively-farmed pigs raising concern for animal welfare, e.g. related to the practice of routine tail docking. To reduce tail biting pigs are provided with enrichment materials. EU legislation requires that pigs have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities. In order to meet this directive many pigs are provided with a metal chain with or without a rather indestructible object attached to the chain. The European commission recently revised current guidelines as to what constitutes adequate enrichment, apparently moving into the direction of the status-quo in welfare schemes. Building on extensive previous work at Wageningen UR Livestock Research, especially on the modelling of pig enrichment (the so-called RICHPIG model) a review is presented of our current state of knowledge. In addition, an outline is given as to how so-called AMI-sensors, measuring Animal-Material Interactions (AMI) (semi-)automatically, can be used to assess the pig’s need for enrichment, also in relation to aspects associated with health status, such as feed restriction, biting wounds and streptococcus infection. It is suggested that the use of chains with or without rather indestructible materials such as pipes, balls or (hard)wood is generally inadequate to enrich the pens of intensively-farmed pigs. An evolutionary mechanism appears to be underlying the causation of multifactorial welfare problems in general, the issues of enrichment, tail biting and tail docking in pigs in particular. In this respect ongoing selection for increased resource efficiency has been exerting a profound impact on livestock production. Various routes are explored as to how persistent welfare problems may be resolved, including a method that has been called Intelligent Natural Design (IND).

By contrast, to improve the chain further 7mm stainless-steel anchor chains may be recommended for growing pigs over the cheaper c-chain shown here, as anchor chains have heavier and more rounded shackles.

Tail docking in the EU: A case of routine violation of an EU Directive

Tail docking in the EU: A case of routine violation of an EU Directive

Abstract

The question of tail docking in pigs is an ongoing problem despite the fact that it should have been solved long ago. In the Council Directive 2008/120/EC it is clearly stated that routine tail docking in pigs are prohibited and enrichment materials for the pigs must be provided, which is in line with the high animal welfare standards that the European Union aim for. This directive is in force in all member states. The habit of tail docking is widespread as a simple comparison by two reports by EFSA shows. We present these results together with results showing that some countries, like Sweden, Finland and Lithuania manage to still keep their production without tail docking routinely. We therefore suggest that the gap between the strong intentions of prohibiting tail docking in the directive and the weak (or non-existent) enforcement of it in most countries in the EU needs to be closed. Of the arguments saying that this will be a troublesome task, we will here focus on two of them. The first is that the directive is unclear or actually allows tail docking. The second is that the habit of routine tail docking is economically profitable. Both these arguments will not hold. There are three ways to bridge the gap. The first is to lower the threshold, lowering the animal welfare level in the directive. We believe strongly that this solution is contradictory to the trend in today’s legislation about animals and not in line with the Lisbon treaty. The second is to demand stronger enforcement which is in line with the EU Strategy for the Protection and Welfare of Animals 2012-2015. The third is to accept that different countries will not enforce the directive, then leaving it to the consumer to choose between more or less animal friendly pork. EU seems to adopt this way in contrast to the EU AW Strategy. To properly inform consumers about animal welfare is a good help although it demands a lot of resources and is a rather slow process. Therefore, in order to have a rapid solution to the gap one need to have a stronger enforcement of the law.

European commission initiative to reduce tail docking and improve enrichment

March 2016 the European Commission takes another step to reduce tail docking and improve enrichment for pigs as part of its animal welfare strategy.

Here are some relevant phrases from the announcement made on the Commission’s website:

The welfare of pigs is assured by Council Directive 2008/120/EC.

It applies to all categories of pig and lays down minimum standards for their protection:

  • Providing permanent access to …. materials for rooting and playing

COMMISSION RECOMMENDATION (EU) 2016/336 of 8 March 2016 on the application of Council Directive 2008/120/EC laying down minimum standards for the protection of pigs as regards measures to reduce the need for tail-docking.

STAFF WORKING DOCUMENTpdf(706 kB) on best practices with a view to the prevention of routine tail-docking and the provision of enrichment materials to pigs [SWD(2016)49 final] Following the adoption of the Commission Recommendation (EU) 2016/336 as regards measures to reduce the need for tail-docking, the staff working document provides useful tools to a harmonised understanding on how the provision of manipulable material and avoidance of tail-docking can be practically achieved.

The working document recognises that proper enrichment is important to help prevent tail biting, and hence the need for tail docking.

Specified as unsafe are synthetic ropes, tyres, dry wood, dry sawdust, poorly stored straw, untreated peat/mushroom compost and dirty objects.

Furthermore proper enrichment should have one or more of the following qualities:

  • Edible or feed-like (to eat or smell)
  • Chewable (to bite)
  • Investigable (to root)
  • Manipulable (to change its location, appearance or
    structure)

Provision should be

  • of sustainable interest
  • accessible
  • of sufficient quantity
  • clean
MATERIALS OF MARGINAL INTEREST
Materials of marginal interest should not be used as essential or single component of pig
enrichment materials. They can provide distraction but should not be considered as
fulfiling the essential needs of the pigs. Other materials should also be provided.
Materials of marginal interest include objects, such as hard plastic piping or chains.
Marginal materials may supplement suboptimal materials like stones or strawdust briquette.

Workshop 3: Tail docking of piglets

The workshop on tail docking of piglets at the Pig Welfare Conference in DK had a very interesting poll showing that 95 % of the participants believe that it is realistic to stop tail docking either immediately or within a 10 years period.

Suggested solutions and ways forward for pig welfare (from Workshop 3): Stopping tail docking immediately …and encouraging the farmer to think “out of the box”; sharing information regarding manipulative material.

Saving the pig tail

Anna Valros and Mari Heinonen published a paper called “Save the pig tail” in Porcine Health Management.

Abstract

Tail biting is a common problem in modern pig production and has a negative impact on both animal welfare and economic result of the farm. Tail biting risk is increased by management and housing practices that fail to meet the basic needs of pigs. Tail docking is commonly used to reduce the risk of tail biting, but tail docking in itself is a welfare problem, as it causes pain to the pigs, and facilitates suboptimal production methods from a welfare point-of-view. When evaluating the cost and benefit of tail docking, it is important to consider negative impacts of both tail docking and tail biting. It is also essential to realize that even though 100% of the pigs are normally docked, only a minority will end up bitten, even in the worst case. In addition, data suggests that tail biting can be managed to an acceptable level even without tail docking, by correcting the production system to better meet the basic needs of the pigs.

EU compliance regarding enrichment and tail docking

This post is the abstract of a student report:

Edman, F. 2014. Do the Member States of the European Union comply with the legal requirements for pigs regarding manipulable material and tail docking? Student report 572, SLU, Skara, Sweden. Accessed 17-2-2015.

Abstract

Tail biting behaviour is a major animal welfare issue in intense pig production, as well as an economic issue. To prevent the behaviour, tail docking is practised. It is a painful procedure where a part of or the whole tail is cut off.

There is a lot of research on the subject of tail biting, with a big variety of solutions to prevent the behaviour. Scientists are consistent about that the absence of manipulable material increases the risk for tail biting. Manipulable material works as an environmental enrichment and stimulates natural behaviours of the pig, such as investigation and rooting. It helps pigs to cope with the environment and reduces stress and frustration, triggers that can lead to tail biting.

The legal requirement regarding tail docking state that it shall not be practised on a routine basis and has been in force since the 1st of January 1994. It was strengthened in 2003 and now appears in Council Directive 2008/120/EC which codifies the earlier directives. The legal requirement now states that measures to prevent tail biting shall be taken before practising tail docking, measures such as changing inadequate management systems, changed environment and reduced stock densities.

Pigs shall also have access to a suitable material or object, to be able to perform natural behaviours and prevent tail biting and stereotypies. In the latest version of the directive on pigs this material was defined as straw, hay, wood, sawdust, mushroom compost, peat or a mixture of such.

The aim of this study was to investigate the current situation of compliance with the legal requirements in the directive on pigs, regarding the provision of manipulable material and the routine practice of tail docking. It was also to investigate actions to increase compliance among the Member States in the European Union. A descriptive analysis of available FVO-reports was used, together with written answers from the Competent Authorities and a qualitative interview with people at the Commission and the FVO.

The results of this report showed that 18 out of 28 Member States in the European Union do not comply with the legal requirement regarding the provision of manipulable material, and that 17 of the Member States do not comply with the legal requirement regarding the practice of tail docking. There has not been any actions such as sanctions to increase the compliance among the Member States.

These findings make an overall conclusion possible about the current issues with the compliance of the directive on pigs. There are no further intrinsic actions to increase compliance, due to a lack of responsibility among the involved parties, such as pig farmers, Competent Authorities and the Commision. Due to the lack of intrinsic action, it is an impossibility to conclude when full compliance will be fulfilled.

Routine tail docking of pigs

This post presents the abstract and executive summary of the EU report:

Marzocchi, O. 2014.  Routine tail-docking of pigs. Policy Department C: Citizens’ Rights and Constitutional Affairs, European Parliament, European Union, Brussels, accessed 17-2-2015.

Abstract

Upon request of the PETI committee, the present study examines the issues raised in Petition 0336/2012, the legal framework on the protection of pigs, the level of implementation of the Directive on the protection of pigs in relation to tail-docking on the basis of the available information, the actions being carried out, or that could be carried out, to ensure proper implementation by Member States of the Directive requirements.
Docking a piglet's tail using cautery (hot iron)

Executive summary

The Committee on Petitions (PETI) examined on the 1st of April 2014 Petition 0336/2012 by C.R. (Danish citizen), on behalf of Dyrenes Beskyttelse (Danish Animal Welfare Society), concerning the routine tail-docking of piglets in Denmark1.

The petition raised the issue of the lack of implementation in Denmark, as well as in most EU Member States, of Council Directive 2008/120/EC laying down minimum standards for the protection of pigs, in relation to the rules governing the tail-docking of pigs.

The Commission recognised during the discussion that the implementation of the Directive in this regard is not satisfactory, but stated that it did not intend to launch infringement proceedings nor to propose amendments to the Directive, considering these actions as not appropriate. It stated instead that it preferred to rely on guidelines for Member States to ensure better implementation of the Directive, as well as on e-learning tools that are currently being developed. It also pointed to upcoming initiatives, such as framework legislation on animal welfare.

On the same day, PETI committee coordinators discussed the petition, the unsatisfactory implementation of the Directive, as well as the refusal by the Commission to launch infringement proceedings against non-compliant Member States. It was decided to request the Policy Department to analyse the issues discussed so to allow the committee to re-examine the matter during the new parliamentary term, including by potentially deciding to send a delegation to a number of Member States to investigate on the effective implementation of the Council Directive.

The present study addresses the PETI coordinators’ request to analyse the issues raised in the petition, the legal framework on the protection of pigs, the level of implementation of the Directive on the protection of pigs in relation to tail-docking on the basis of the available information, and the actions being carried out, or that could be carried out, to ensure proper implementation by Member States of the Directive requirements.

The study concludes that:

all the available evidence points at persisting high rates of non-compliance in the large majority of Member States in relation to the ban on routine tail-docking of pigs;

-Commission guidelines, training and e-learning tools, including on enrichment and manipulable materials, as well as a possible Framework Law on Animal Welfare, can be useful instruments to support farmers and Member States’ authorities in the implementation of the Directive; – at the same time, these could be accompanied by a stricter enforcement policy, notably since the Directive has been in force for more than 10 years (while the ban on routine tail-docking has been in force for more than 20 years); – the Commission could be bolder and prepared to launch infringement proceedings as an enforcement tool of last resort, as the mere prospect of serious action may prompt Member States to comply; – the Commission could also more systematically collect, monitor and publish information on the transposition of the Directive by Member States, as well as on their degree of compliance with the ban on routine tail-docking of pigs, including through inspections and specific requests to Member States.

Box 1: Tail-biting, tail-docking, routine tail-docking, enriching and manipulable material

Tail-biting, ie a pig biting another pigs’ tail, is an abnormal behaviour caused by several risk factors, notably by a poor or stressful environment frustrating the normal investigative behaviour of pigs (which are among the most intelligent and curious animals) in common intensive farming conditions. Tail-biting can result in infections, affecting the health and well-being of tail bitten pigs and can lead to tail-biting outbreaks.

Tail-docking is the practice of removing the tail or part of the tail of a pig, while routine tail-docking is the systematic docking of the tail of pigs, normally done in the early days of life, with the aim of avoiding the risk of tail-biting. It is done without anaesthesia, though it is a mutilation which is painful. Tail-docking can cause long-term chronic pain and infections, as well as redirection of the biting behaviour to other body parts, such as ears and legs.

Enriching and manipulable materials are materials such as straw, hay, wood, sawdust, mushroom compost and peat or a mixture of these, with which pigs can satisfy their explorative, playful and foraging behaviours. Studies have highlighted that the provision of such materials has a positive effect on pigs, reducing the risk of tailbiting.
