The spectacular increase that pig production has experienced in recent years has generated a significant demand for information on the management and operation of pig farms. This book, created to fill this gap, reflects the work and experience of the authors, who have met the objective of creating a book with very practical contents and information rigorously based on scientific publications and on their own experience. This book aims to update knowledge and showcase the latest developments relating to the management of porcine farrowing units (physiological aspects of farrowing, facilities, organisation of farrowing sows, etc.).
