"The result is a refreshing balance between readability and practicality, underpinned by true science and the appliance of science... as a comprehensive resource on the breadth of information available with the combination of general principles, up-to-date advice, coupled with an excellent provision of further reading and resources for every chapter, makes this an essential addition to any poultry library!" (Dr Stephen A. Lister, review in Avian Pathology) Diseases remain a significant burden to poultry production and its future, with outbreaks of disease resulting in catastrophic financial losses to the sector. Whilst it is widely recognised that vaccines have a major role in inducing protection, they can only be considered as part of the solution to this rapidly growing problem. Optimising poultry flock health instead reviews ways of optimising preventative measures to reduce the risk of disease in flocks. The book reviews the wealth of recent research on the mechanisms of transmission for infectious diseases and how this understanding can be used to improve poultry flock health. By showing how poultry flock health can be optimised at different stages of production, the book showcases the extent of preventative measures available to farmers and producers, as well as how these measures can be implemented effectively to protect their flocks against disease.
