With the increasing move towards large-scale farming the importance of disease prevention at herd level is becoming ever more apparent. Rather than concentrating on the health of the individual animal Dairy Herd Health takes a population level approach to disease prevention, investigation and control. Covering frequently occurring and economically important conditions including mastitis, lameness, infertility, metabolic diseases, Johnes Disease and BVD the book looks at herd patterns of disease, the underlying principles of disease, monitoring of conditions and control strategies. The editors adopt a real-world approach, considering the impact of dairy herds on the environment, and addressing the farmer-vet relationship - encouraging continuous veterinary involvement in herd planning, providing practical models of the implementation of herd health and making a realistic assessment of the decision making process. Dairy Herd Health provides practical coverage of this important issue, ideal for veterinary surgeons and students as well as agricultural consultants and farm managers.--COVER.
