Tail and Ear Lesions in Pigs: Welfare Implications and Slaughterhouse Relevance

Share This Post

Context of the Problem

Tail and ear lesions in pigs are caused by biting and chewing behaviours directed at other pigs’ tails and ears. Both tail as well as ear biting are multifactorial problems, and several factors such as genetics, health and housing environment can contribute to an outbreak. Causes differ between individual farms, which complicates interventions. Even when tails are docked, biting can persist and causes painful wounds, infections and long-term health problems. These lesions are a clear welfare concern, since pigs suffer from prolonged pain and, in severe cases, even systemic infections. Economically, tail and ear lesions reduce carcass value through trimming and downgrades, while raising food safety concerns.

Monitoring and aWISH Project

Lesions can persist until slaughter, providing a record of on-farm conditions during the fattening period. Slaughterhouses can implement standardized scoring systems for tail and ear lesions to help quantify the problem and track improvements over time. As part of the aWISH project, an automated system based on cameras and appropriate algorithms to score these lesions is being developed. Feedback to farms is provided via a data platform, aiming to provide a status quo for farmers and to encourage animal welfare improving actions. Maintaining communication between farms and slaughterhouses regarding lesion patterns allows corrective measures to be implemented quickly, reducing the frequency and severity of tail and ear injuries over time.

Best Practices

Since tail and ear biting has multifactorial causes, intervention strategies need to be adapted to the individual farm. For instance, improving environmental enrichment, lowering stocking densities and ensuring a good barn climate can reduce biting events. Feeding-related improvements such as ensuring a good feed quality or providing more feeding and drinking space can further have an influence on the occurrence of tail and ear lesions. To prevent outbreaks, pigs should be observed daily for signs of tail and ear biting and intervention strategies, including the separation of biters and victims and offering emergency enrichment such as manipulable materials, should be implemented.

1. aWISH Introduction

We would like to invite you to participate in the aWISH Expert Panel, as we believe that your experience and knowledge will contribute greatly to a key consultation body of the project. aWISH is a 4-year project funded by the European Union under the Horizon Europe Research and Innovation programme. Before you decide to participate in the aWISH Expert Panel, please take the time to read this document carefully to understand what your involvement will be in our project’s activity. If there is anything you do not understand, please feel free to ask questions.

1.1 What is the aWISH project about?

In the EU, a challenge that still remains is to reconcile the social and moral demand for a high level of animal welfare with other pillars of sustainable livestock production. Indeed, 82% of Europeans believe that farm animals should be better protected than they currently are. A broad definition of animal welfare refers to the feelings and physical well-being of an individual animal. Broilers and pigs are the farm animals EU citizens care most about, and they are also the most important meat-producing animals in the EU and worldwide. Both pigs and broilers have significant welfare problems at all stages of production (on-farm, loading and transport, unloading and slaughter), leading a growing number of citizens to question the social license to produce. Ambitious and effective, but also practical and efficient solutions are needed. This is where the aWISH project comes in to fill this gap! The aim of aWISH is to develop and provide a cost-effective solution for assessing and improving the welfare of meat-producing livestock in Europe. The aWISH solution is based on the automatic monitoring of animal-related indicators at slaughter. The necessary technologies will also be developed to collect complementary data on farm or during transport. Pilot and development activities will be carried out in 6 broiler and fattening pig production chains across Europe using a lean multi-actor approach to test and validate the project results. A catalogue of animal welfare indicators will disseminate all validated indicators and standardised data collection methods. Best practice guides will be developed to improve key aspects of animal welfare in pigs and broilers and to help external stakeholders use aWISH technologies and tools. In this context, the aWISH project will set up expert panels that will be composed of representatives of actors from the entire farm to fork value chain across the EU. The expert panels will have the function to retrieve and share feedback on technology, processes, farming practices, industry, sector regulation and markets, as well as society and perceptions. In this way, stakeholder participation in expert panels could help initiate interdisciplinary dialogue, promote interaction with target groups and associations, and strengthen trust between different actors.

2. Useful Information

2.1 Is my participation voluntary and what does it involve?

Your participation in the aWISH project is entirely voluntary. If you decide to participate in an aWISH activity, we will ask you to sign an Informed Consent Form to collect and process your data. The project will last 48 months, but you will only participate for as long as you wish.

2.2 Purpose of personal data collection

As mentioned above, the expert panel will have the function to retrieve and share feedback on technology, processes, farming practices, industry, sector regulation and markets, as well as society and perceptions. In order to do this effectively, we need to process some of your personal data:
  • Your contact information
  • Demographic information (age, gender, country of origin)
  • Professional information (where do you work, what position do you hold, what is your area of expertise)
  • Personal opinions on the subject

2.3 What we will do with your data

The information you provide is confidential. Your consent form will be kept separate from the observations collected during the course of the project activity. We will share your data with other aWISH project partners involved in the data analysis and reporting process. Once the data is analysed, a report of the findings may be submitted for publication. The project's deliverables that will be derived by this activity will not include your personal data or any other information that could identify you. The results of this project activity may also be shared with representatives of the European Union (e.g. the Project Officer evaluating the project's or the reviewing EU agencies). Only broad trends will be reported and it will not be possible to identify any individuals.

3. Access, deletion of information or withdrawal of consent

Under the EU’s General Data Protection Regulation (GDPR), you have the right to request to: (i) provide you with a copy of your data; (ii) correct your data if you believe they are inaccurate; (iii) erase your data; (iv) restrict or stop processing your data; or (v) provide your data in an appropriate format and transfer them to another organisation. In addition, you may withdraw your consent and therefore your participation at any time without consequence. Anonymous data already collected will be used as we cannot trace the information back to you. No further data will be collected or other procedures carried out in relation to your information. If you wish to have the personal data we hold checked, amended, corrected or deleted, or if you wish to withdraw your consent, you can contact the responsible partner listed below.
