This extensively revised edition of what is the definitive textbook on diseases in cattle in New Zealand and Australia is written from the perspective of the veterinary practitioner encountering the diseases in cattle on a farm. The reader is provided with a detailed outline of the diagnostic methodology based on clinical examination of body systems, with confirmation by ancillary tests and responses to treatment. The principal authors and guest contributors bring a wealth of practical, academic and research experience to this text. It covers all the important diseases of cattle, with particular emphasis on clinical examination, diseases of the gastrointestinal tract, lameness, mastitis, and reproductive disorders. The chapter on practical therapeutics for the cattle veterinarian is of great value for veterinary students, and during on-farm consultations.
