An authorisation procedure for mass-produced farm animal housing systems with regard to animal welfare

In 1981, an authorisation procedure regarding animal welfare was introduced in Switzerland for mass-produced housing systems and equipment for farm animals. When asking for an authorisation, the manufacturer or importer of a housing system or equipment must send detailed documentation (plans, measures, technical data) to the Federal Veterinary Office. The authorisation can only be given if the housing system or equipment is in accordance with the requirements of the Swiss animal welfare legislation. Whenever possible, a decision is made on the basis of literature or experience with similar equipment. In some cases, however, practical tests are required. Such tests may include veterinary, physiological, and behavioural measurements to assess animal welfare. Authorisations are given by the Federal Veterinary Office. It may consult an advisory board which consists of experts in animal husbandry, animal housing construction, and animal protection. Over the last 23 years, more than 1300 authorisations were given, and 16 applications were rejected. The manufacturers may appeal against a decision of the Federal Veterinary Office. To illustrate the authorisation procedure and the indicators used to assess animal welfare, five examples of testing of housing systems or equipment are given. In conclusion, pre-testing of farm animal housing systems that are intended to be mass-produced is a promising way to increase and ensure product quality from livestock systems.
