The handbook summarizes the results of the Core Organic Cofund project POWER, aiming to increase animal health and welfare of organic pigs while reducing the environmental footprint of the farming systems. It provides a common toolbox of knowledge-based strategies for designing and managing concrete outdoor runs, reducing piglet mortality and health problems and improving system resilience and sustainability. Best practices and innovative examples from across Europe are presented to inspire and facilitate the continuous development of an economically competitive production, which meets the principles of organic farming.
