Pig farming has recently moved from an extensive outdoor system to an intensive indoor farming system. This has improved productivity and profitability, but also increased disease, use of pharmaceuticals and debates about housing and welfare. This practical book examines pig health from a herd point of view, covering disease outbreaks, drug dosages, sow and boar management, reproduction, common surgical procedures, nutrition, public health, biosecurity, record keeping, health and safety and welfare monitoring.
