      To the most important people in my life: my parents Barbara Fechner and the late Hans Passler, my wife Nicole, my son William, and my American family, the Borgmeyers. Thank you for your unwavering love and support! And to my colleagues – the Auburn family – for their collegiality, friendship, and words of wisdom.

      I would first like to start by thanking Dr. Hui‐Chu Lin for inviting me to participate in the second edition of this textbook. It is exciting to see anesthesia and pain management for farm animals advance and to know that practitioners are utilizing this information to improve the lives of the animals and clients they serve. I therefore dedicate this book to those practitioners, some of whom have been students of mine, who tirelessly endeavor to provide care to the best of their abilities.

      Preface

      The first edition of Farm Animal Anesthesia: Cattle, Small Ruminants, Camelids, and Pigs was published in 2014. Since then we have received encouraging comments from veterinarians on the usefulness and practicality of the information provided in the book. Many veterinarians complimented the ease of searching for the information needed for their daily practice: anesthetic patient care, drug dosages, and drug combinations for different circumstances and surgical procedures (Chapters 1–6 and Chapters 8 and 10). Information on the local and regional anesthetic techniques and pain management chapters provided many options to minimize perioperative and postoperative pain, and reduce patient suffering (Chapters 7 and 10). The chapter on regulatory and legal considerations of anesthetics and analgesics ensured avoidance of human consumption of drug residues in meat and milk from food‐producing animals (Chapter 11). The euthanasia chapter offered clear information on different methods that a veterinarian can use to effectively and humanely end an animal's suffering when there are no available treatments that can improve an animal's deteriorating condition (Chapter 12). The contributing authors and editors are extremely proud and honored that the first edition of the book was well received by our professional colleagues, who continue to provide best patient care.

      Great advances have been made in farm animal medicine and surgery in the recent years. Many farm animal species are now also kept as companion animals, particularly small ruminants and potbellied pigs. Advanced treatment options and complex surgeries have become available. The second edition of the book includes new information published since the first edition, including newer anesthetics and analgesics, surgical procedures, fluid therapy, and updates on regulations pertaining to anesthetic drugs used in farm animals. We believe farm animal veterinarians will continue to find the second edition to be a useful and practical guide for anesthetics and pain management in their daily practice. Included in this edition are videos of different local and regional anesthetic techniques to guide veterinarians to perform nerve blocks for intended surgeries safely and effectively. Also included is information on the application of neuromuscular blocking agents and the clinical use of ventilators when complicated and long duration surgery is necessary. As surgical techniques progress, the increased complexity will require that some patients are administered neuromuscular blocking agents and the knowledge of the use of these drugs and mechanical ventilators will become an essential part of anesthetic management.

The editors greatly appreciate the contributing authors, Drs. Benjamin Newcomer, Manuel Chamorro, Jessica Rush, and Jenna Workman Stockler, for their work and efforts in making this book a complete book on farm animal anesthesia. We thank the illustrators, Kim Crosslin and Katlyn King, for their picture‐perfect artwork and Dr. Ray Wilhite for excellent anatomical images. We also want to thank Merryl Le Roux, Managing Editor, and her staff at John Wiley & Sons for their patience and much needed assistance throughout this process.
