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.
