Archiving. The Animal Health Service (Gezondheidsdienst voor Dieren, or GD) works with farmers, veterinary practitioners, government and agricultural organizations to improve animal health in the Netherlands. Farmers can have their livestock checked by the GD for possible infections or other health problems. Armed with the results, the GD advises farmers on how they can avoid or solve problems. By comprehensively monitoring Dutch livestock, the GD can track down problems at an early stage and identify new diseases. The company boasts one of the world’s largest veterinary laboratories.
