Bursitis in Pigs: Welfare Implications and Slaughterhouse Relevance

Share This Post

Context of the Problem

Bursitis in pigs represents a significant welfare concern. It describes the development of fluid-filled sacs (bursae) on the hock joints, often characterised by swelling and soft lumps. They form as a reaction of the skin to lying on hard surfaces or as a result of trauma caused by slippery or damaged flooring. Hard, abrasive flooring such as concrete, a lack of bedding, and high stocking densities can all contribute to the occurrence of bursitis. The condition can be very painful for affected pigs, and complications such as infection of the affected area are possible. Severe cases can also lead to lameness and impaired mobility as well as to the downgrading of carcasses.

Monitoring and aWISH Project

Bursitis can be monitored both on-farm and at the slaughterhouse. It is a key animal based welfare indicator and directly reflects on-farm welfare. While bursitis is not specifically monitored as part of the aWISH project, it remains closely linked to housing conditions and management practices that have a strong impact on pig welfare. Observing its occurrence can help farmers and other stakeholders identify environmental risk factors and take targeted action to improve living conditions.

Best Practices

The prevention of bursitis should mainly focus on flooring and housing conditions. Providing bedding such as straw or using rubber floor mats, especially in the lying area, can significantly reduce the risk of lesion development. Regular checks of floor condition are also essential, and damaged slats should be repaired promptly to prevent trauma. Wet or slippery floors should be avoided as pigs can develop bursitis when they slip or fall. Sharp edges in the whole pen as well as other hazards should be removed to minimize the risk of injury. Dirty areas, especially in resting zones, should be avoided to prevent infections. Lower stocking densities can further improve animal welfare by allowing pigs to rest more comfortably. In addition, health monitoring of all animals and prompt treatment of injured pigs 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.
