Collecting and monitoring welfare data during catching, loading and transport is beneficial for the development of new practises and technology. In Sweden, data is collected from every flock that are send to slaughter from several sources, e.g. manually assessing birds at arrival, the official veterinarians’ inspections and condemnations at slaughter, and gathered in a national database. The data is used as KPI’s to monitor animal welfare during catching, loading and slaughter, to prevent systematic problems and as base for education. Example of such data is transport mortality (DOA), injuries (bruising, wounds, wing damage) and making sure no animals have gotten stuck in the transportation crates. The data is used on both a national and farm level for quality insurance. Challenge with this kind of monitoring is calibration of assessors at the abattoirs and to identify the origin of the problem, which usually are multifactorial. The data collected are used as a foundation to develop guidelines on how to handle the birds with care during catching, loading and transport. Some examples of guidelines for mechanical catching (the most used practice in Sweden) are as follows: the loading machine must be equipped with a euthanasia station, and staff must be trained to euthanize sick or injured chickens in the correct manner; loading machines and forklifts must be fitted with blue working lights; the belt speed must comply with the requirements of the transport system and adapted to bird behaviour; the containers must be manually checked to make sure no animals are stuck in any way.
