Description

Fully updated new edition of a classic quick reference to common surgical procedures in farm animals

Noordsy’s Food Animal Surgery, Sixth Edition is a classic quick reference to surgical procedures in livestock and companion farm animals. With a practical outline format, this book makes it easy to locate essential information on common surgical techniques, presenting 39 chapters across 6 sections for ease of navigation. The book is a helpful memory refresher for procedures or species encountered less frequently, enabling readers to build confidence in learning new surgical techniques.

Chapters review presurgical preparation, perioperative care and restraint, and surgical procedures of the major body systems, and the Sixth Edition has been updated throughout to remove outdated procedures and equipment, making way for new techniques and a focus on evidence-based best practices. Most illustrations have been updated to more accurately depict anatomy, providing surgeons with a clearer understanding of how to perform the procedures, and numerous clinically relevant photographs and illustrations have been added to better convey concepts and techniques.

A companion website allows readers to view and download figures from the text and contains study questions from the end of each chapter along with the answers to those questions.

Noordsy’s Food Animal Surgery includes information on:

• Surgical restraint, local, epidural, general, and postoperative anesthesia/analgesia, surgery of the head and neck, and surgical treatment of cattle with ocular disease

• Umbilical hernias and infections, laparotomy, rumenotomy, fistulation, cannulation, pericardiotomy in cattle, abomasal surgery, surgical treatment of intestinal disease, and rectal prolapse repair

• Surgical treatment of the male and female urogenital systems including conditions associated with urolithiasis and mammary surgery

• Ligament and tendon surgery, foot and claw surgery, joint surgery, and common fractures and dislocations

Noordsy’s Food Animal Surgery is an essential resource for veterinary students and large animal practitioners who care for farm animals.
