Summary:

"Increasing concern about over-reliance on antibiotics (resulting in antimicrobial resistance), as well as broader concerns about animal welfare, have put greater emphasis on preventative measures in maintaining the health of farm animals. Herd health management (HHM) programmes take a population approach based on quantitative epidemiology which makes it possible to assess disease risk and, as a result, prevent and manage diseases more effectively. Improving dairy herd health reviews key challenges in dairy herd health management, such as effective monitoring and diagnosis of infectious diseases, as well as recent developments in areas such as disease prevention and disease surveillance. This collection reviews HHM issues across the dairy cow life cycle, from reproduction and calf health to the transition stage and replacement of stock. Later chapters discuss the successful implementation of HHM programmes in specific instances, from maintaining udder and hoof health, to preventing metabolic disorders, bacterial and viral diseases, as well as parasitic infections"-- Provided by publisher.
