title: [Possible methods of control of virus disease in swine today and in the future. II. Specific applications (author's transl)].
abstract: The four alternatives discussed in the previous paper (5), are applied to a number of virus infections which are common in pigs. The enzootic state of SMEDI enteroviruses, vomiting and wasting virus and parvovirus should be promoted by bringing the young gilts into close contact with the older sow population at a sufficiently early stage. There should preferably not be a change of herd for primiparous sows during pregnancy. In parvovirus infection, maternal immunity may be so prolonged that gilts will only be infected after the time of breeding. Therefore, mating should preferably be postponed until they are nine months of age, unless previous serological tests have shown that they are in a state of active immunity. Considering the present disease situation of swine fever in several continental West European countries and consequently they high number of existing virus sources, compulsory vaccination of sows and fattening piglets is recommended against this virus on an international scale for at least three years. This vaccination can be omitted only after the number of outbreaks has been reduced to a very low level. Vaccination is the only possible alternative left in the combat against Aujezky's disease. Caution is undoubtedly indicated in using live vaccines in these cases. So far, methods have not become available for the effective control of transmissible gastroenteritis and prospects are not encouraging. The possibility of eradication of transmissible gastroenteritis is discussed.
