The ever-changing world of cattle farming requires farmers to be up-to-date with best-practice procedures and the latest advances in husbandry techniques. Now in its 4th edition Roger Blowey's updated version of the acclaimed A Veterinary Book for Dairy Farmers deals with newly emerging problems in cattle farming as well as covering the necessary knowledge required for maintenance and prosperity.



In this practical guide to animal health and husbandry, the author highlights developments in established conditions including lameness, Johnes, BVD and mastitis. Other updates include the prevention and treatment of emerging diseases such as Schmallenberg and Blue Tongue and current issues in farming such as developments in calf rearing and increasing incidence of botulism and antimicrobial resistance.



Translating the latest developments in veterinary research coupled with a long career in veterinary medicine the author provides a comprehensive and practical text for dairy farmers, stockmen, veterinary academics and students alike to navigate this changing field.
