Sažetak
The article deals with application of ultrasonic atomisation for immunoprophylaxis of poultry against viral diseases. Princples of liquid droplets formation from saline/vaccine suspensions in which cavitation and resonant capillary wave break-ups are generated my means of an ultrasonic field have been analysed. A three-way optimisation process has been applied: results from medical inhalation theory have been used for optimisation of droplet size and distribution; frequency of the ultrasound field has been determinated which generates droplets of given size, and an ultrasonic transducer has been designed for generation of the ultrasonic field which could provide production of required as a dynamic process, whith aerosol carried on by air flow to the vaccianation chamber, where one-day chicken are vaccinated orally while breathing regulary. Results of research in an experimental vaccination equipment show increased efficiency of the method in comparison to others. Vaccine viruses have been found in the lung tissue already within 6 hours and in the bursa of Fabricius within 24 hours after vaccinations.
