[Use of lapinized "C" vaccine as aerosol in immunoprophylaxis against swine fever].
Lapinised vaccine, strain "C", was used on 3500 fattening pigs on two farms in experiments for aerogenic immunisation. Two ordinary pigsties were modified for use as aerosol application chambers. A USSR-made disc-type aerosol generator, DAG-2, was used for vaccine dispersion. Piglets were allowed to be in contact with the aerosolic vaccine antigen for about 60 minutes. No deterioration in general health condition was observed, when longer contact periods were allowed. Existing respiratory disorders did not aggravate. Immunity was obtained seven or eight days from the time of aerosolic immunisation and lasted not less than ten months. The prospects of such groupwise immunisation of pigs against swine fever under conditions of industrialised rearing are discussed against the background of epizootiological and economic aspects. The results so far obtained from aerogenic immunisation form a good basis for its further development and eventual use under conditions of industrialised swine keeping.
