Benefits of technology

[0017]Like the UlvaVac, the disclosed extended-range spray applicator is battery powered. As well as spinning the disc atomizer that produces the uniform droplets, the battery also powers an air supply means, which may be a blower motor. The combined action of the air supply means and the rotating disc atomizer distributes the vaccine over an area of up to about 5 to about 10 meters long and 2 meters wide. The about 5 to about 10 L of liquid that is contained in the machine's reservoir should last about 10 to about 30 minutes when a yellow nozzle is used.

[0018]For broilers, protection from good spray vaccination reduces the possibility of economic losses caused by diseases that enter via the respiratory tract and can cause weight loss and general poor performance of the flock. For layers and breeders, as well as respiratory disease, Infectious Bronchitis viruses can damage the kidneys and oviduct with infections resulting in false layers, drops in production and poor quality eggs.

[0019]By using the instantly disclosed extended-range spray applicator, specifically for use in poultry, vaccines and probiotics are delivered directly to the upper respiratory system—including the eye, nasal cavities and trachea. The device yields a uniform droplet size, is not too heavy to use and i

Problems solved by technology

Nevertheless, it is not always synonymous of efficacy as it can lead to vaccination failures uneven uptake and/or development of post-vaccination reactions PVR if it is not properly managed.

However, the principal cause of sheet breakup stems from interaction of the sheet with the surrounding air, whereby rapidly growing waves are superimposed on the sheet.

However, the time allowed for spraying is determined by the length of time during which the shed/house ventilation can be inoperative.

The UlvaVac provides the uniform droplet size required for vaccinating avian animals including chickens, including broilers, but its range is limited i.e. the user must be relatively close to the birds.

For example, if increasing the speed of the air flow caused the vaccine droplet size to become too small, the vaccine would end up in the lungs of the birds, which is not desirable.

Furthermore, if higher speed caused the vaccine to be sprayed non-uniformly, some of the birds would be under-protected, while others would be over-dosed, and suffer from side effects.

For broilers, protection from good spray vac
