Since the 1980s, there has been a growing demand for white meat over red meat, resulting in the development of small poultry farms and backyard poultry units into commercial farms. The use of intensive poultry keeping methods and the rearing of multiple species of poultry together has led to a rise in disease problems. Since the inception of intensive poultry production worldwide, farmers have struggled with severe diseases and significant economic losses.

To keep up with the rapidly expanding poultry industry and meet the increased demand for poultry products, a thorough understanding and working knowledge of poultry diseases will be essential. This book aims to provide veterinary students with a comprehensive understanding of poultry diseases.

In addition, the book will be beneficial to personnel at poultry disease diagnostic laboratories and progressive farmers. The book is divided into seven sections, covering avian, bacterial, viral, fungal, parasitic, and nutritional deficiency diseases, as well as miscellaneous disorders affecting poultry. The book contains a total of 74 chapters in a concise format.

Each chapter focuses on the etiology, transmission, epizootiology, clinical signs, gross and microscopic lesions, diagnosis, treatment, and control of the respective disease. When necessary, the book also mentions zoonoses. The book includes relevant images and tables to enhance the reader's understanding of the diseases.
