Characterization of short- and long-term mechanical sensitisation following surgical tail amputation in pigs. By Pierpaolo Di Giminiani, Sandra A. Edwards, Emma M. Malcolm, Matthew C. Leach, Mette S. Herskin & Dale A. Sandercock. 2017. Nature Scientific Reports.
Commercial pigs are frequently exposed to tail mutilations in the form of preventive husbandry procedures (tail docking) or as a result of abnormal behaviour (tail biting). Although tissue and nerve injuries are well-described causes of pain hypersensitivity in humans and in rodent animal models, there is no information on the changes in local pain sensitivity induced by tail injuries in pigs. To determine the temporal profile of sensitisation, pigs were exposed to surgical tail resections and mechanical nociceptive thresholds (MNT) were measured in the acute (one week post-operatively) and in the long-term (either eight or sixteen weeks post-surgery) phase of recovery. The influence of the degree of amputation on MNTs was also evaluated by comparing three different tail-resection treatments (intact, ‘short tail’, ‘long tail’). A significant reduction in MNTs one week following surgery suggests the occurrence of acute sensitisation. Long-term hypersensitivity was also observed in tail-resected pigs at either two or four months following surgery. Tail amputation in pigs appears to evoke acute and sustained changes in peripheral mechanical sensitivity, which resemble features of neuropathic pain reported in humans and other species and provides new information on implications for the welfare of animals subjected to this type of injury.

“This guide aims to give practical advice to pig farmers surrounding the complex
issue of providing suitable environmental enrichment to pigs. It provides
useful information from the knowledge of farmers, researchers and scientific
literature on the different ways environmental enrichment can be provided for
differing types of housing and systems. The information is set out in sections
by housing type, and in each, the types of enrichments that are most suited
to each system are discussed, including their properties, how to present
the enrichment, quantities and practical considerations, such as ease of
installation, maintenance and costs.” (cited from the introduction in the guide).
The effect of mixing piglets after weaning on the occurrence of tail-biting during rearing
By Christina Veit, Kathrin Büttner, Imke Traulsen, Marvin Gertz, Mario Hasler, Onno Burfeind, Elisabeth grosse Beilage, Joachim Krieter, 2017. Livestock Science 201: 70–73.
The aim of this study was to investigate the effects on tail-biting during rearing of housing piglets of the same litter compared to piglets from different litters. The treatments “litter-wise” (LW, n =240) and “mixed litters” (ML, n =238) were housed in five identical units. Each tail was scored regarding tail lesions and tail losses once per week with a four-point score (0= no damage/original length to 3= severe damage/total loss). The effect of week after weaning had highly significant influences on tail lesions (p<0.001). Tail-biting started in the second week after weaning, with an increasing severity during rearing. First tail losses were observed in the fourth week after weaning. The batch and the interaction between treatment and batch had highly significant influences on tail losses at the end of rearing (p<0.001). Depending on batch, piglets in the LW or ML treatment were more affected by tail-biting.
Report identifies good practices for rearing pigs with intact tails
DG Health and Food Safety – European Commission
A new report provides evidence that there are solutions to counter the commonly held belief that rearing pigs and avoiding tail docking is impossible.
Based on visits to three countries where tail docking is not performed routinely, it summarises good practices to rear pigs with intact tails. It finds that the key to do so is to lower stress levels through active management of enrichment materials; feed and air quality; reduction of competition between animals; and good animal health status. Another key factor to ensure intact tails is that farmers rapidly identify tail biters and remove them to prevent the escalation of tail biting.

More gestating sows are being housed in pens where it is challenging to implement controlled exposure to pathogens for disease control (“feedback”). Ice blocks provide a possible vehicle for feedback material in pen gestation. Ice blocks were placed once weekly for 6 consecutive weeks in a pen of approximately 130 sows to test whether sows would interact with the blocks of ice. Sows were housed in a large, dynamic pre-implantation group fed with electronic sow feeders. Each ice block was video-recorded for 1 hour. All sows that contacted it were identified. The number of sows, their duration of contact, and amount of aggression were coded from the video. Median number of sows that interacted with the ice was 94, and increasing the number of ice blocks from two to four per pen increased the median number of sows to contact the ice and the median duration of an individual sow’s contact with the ice, and decreased the amount of aggression at each block. Our findings suggest ice blocks are a convenient vehicle for controlled exposure of feedback material to gestating sows housed in large pens. However, additional studies are needed to validate pathogen exposure with this method.
What do you see?
Please have a look at this pig’s tail. You may note that contrary to most EU pigs, this Finnish pig has a curly tail. In addition, please note that this pig does not only has a curly tail. Its tail also has a hairy plume. That is what a pig’s tail should look like: It is the pig’s welfare thermometer.
Curly tail as sign of melting pig-welfare iceberg
The FareWellDock project has accumulated scientific information directed at reducing the need for tail docking in Europe. In this way it has contributed to ending the progressive melting of the pig-welfare iceberg. But sometimes, a picture says more than a thousand words, for the pig’s tail is an iceberg indicator for pig welfare.

4-6th October 2016: Meeting and Webinar on Actions to Prevent Tailbiting and Reduce Tail docking of Pigs
The European Commission Directorate General for Health and Food Safety is organising a three day meeting at the offices of its Health and Food Audit and Analysis Directorate in Ireland on actions to prevent tailbiting and reduce tail docking of pigs.
The programme includes a wide range of relevant topics. It is delivered by experts from industry, Member State Competent Authorities, research bodies, EU institutions and NGOs. Case studies will facilitate the exchange of good practice and workshops will focus on better solutions for the future. The work of the EU FareWellDock project will also be presented at this meeting.
The meeting is aimed at the authorities of Member States, international organizations, scientists, industry and NGOs.
The Agenda can be found below.

Can tail-in-mouth behaviour in weaned piglets be predicted by behaviour and performance? By Camilla Munsterhjelm, Mari Heinonen, Anna Valros. In: Appl. Anim. Behav. Sci.
This study aimed to identify characteristics of pigs performing tail-in-mouth behaviour (TIM; P, n =34), their recipients (R, n =23) and neutral penmates (N, n =31) at two occasions, the first being at weaning (4 weeks of age) before TIM was observed in the pen and the second being at 9 weeks of age when TIM had emerged, but no clinical tail lesions were observed. The groups (n =22) were formed by siblings, two gilts and two castrates. Behaviour was analysed as 24-hour time budgets and continuously sampled during 30minutes of the active part of the day. Category (P, R, N) effects were analysed at individual and (directed) dyad level. P was born significantly smaller than R, but the difference had disappeared at 4 weeks. Growth or sex distribution did not differ between categories. Category differences in performed behaviour were evident at 4 weeks of age, when P showed more overall activity and environmental exploration as compared to R, as well as more bouts of tail-nosing than N. Different aspects of behaviour changed in the different categories between 4 and 9 weeks of age. In P social activity increased significantly and went from no preference at 4 weeks to a significant preference for social actions for R over N at 9 weeks. N was socially passive at 9 weeks while receiving more social behaviour than the other categories. These differences in behaviour suggest that the categories represented different phenotypes of pigs.
