Good progress is being made with the first half of the lairage finished, and the second half hopefully finalized towards the end of June. At that point, the Stremodo (FBN) system to measure stress vocalizations in pigs in the lairage can be properly installed.
The PigInspector (CLK) has been up and running. Extra guiderails have been installed to keep the carcasses stable and correctly positioned in front of the camera.
From a research perspective, things have officially kicked off! Kenny van Langeveld (PhD student, ILVO) and Nienke van Staaveren (researcher, Utrecht University) have been collecting data from pigs on different commercial farms and are following them to slaughter. Through collaboration with Connecting Agri & Food (CAF) and the use of their climate sensors on these farms, we will have access to barn climate data during the finisher period of the pigs. The goal is to link the barn climate to the welfare indicators measured with the aWISH technologies at the Pilot, but also to relate those outcomes of the aWISH technologies to the outcomes of the on-farm welfare assessments where possible. In April, the first pigs went to slaughter and a team of researchers and Vion staff were there first thing in the morning to make sure all went well and pigs could be tracked throughout the slaughtering process. The first samples of exsanguination blood to measure insulin-like growth factor-binding protein (IGFBPs, FBN) as an indicator of stress have also been collected on these pigs. Combined with additional research and routine slaughterhouse measurements (e.g., carcass quality), we will have a comprehensive picture of what has happened with these batches of pigs to answer our research questions. The study will keep going for the rest of 2024 and early 2025 to get a good representation of pigs over the year.
