Summary: | 碩士 === 國立中興大學 === 生物產業機電工程學系所 === 102 === Vaccination for broilers mainly bases on workers in Taiwan. There
are automated machines for broilers-vaccination, but the cost is too high.
Injecting each new born chicken with vaccines spends too much times, it
could lead to cross-infection diseases among chicken. Injecting each new
born chicken with vaccines also makes chicken stress so that loss appetite.
Differ form other technology, this study focous on in ovo needl-free
injection. Injecting in ovo hatching day-18.5 eggs with saline by
needle-free injector, and 100% chicken broke shells at day-20. New born
chicken’s physiology normal although needle-free injector makes embryo
bruising while vaccination. Injecting in ovo hatching day-18.5 eggs with
IB vaccine by needle-free injector. The result is similar with injecting in
ovo hatching day-18.5 eggs by syringes. In ovo vaccination by
needle-free injector can makes chicken with immunization.
