A 2025 report from Zoetis evaluates the performance of in ovo vaccination systems, which administer vaccines to developing embryos inside eggs. The study emphasizes the importance of site-of-injection accuracy for maintaining health and production efficiency.
Why it matters
Precise vaccination is critical for protecting chick health and reducing costly vaccine waste in industrial hatcheries. Identifying effective delivery systems helps producers optimize output and manage biological assets during incubation.
The Embrex system achieved a 99.6% site-of-injection accuracy rate, while competing Device Brand A and Device Brand B recorded 86% and 77.4% respectively. Embrex also removed 100% of infertile eggs and 99.3% of early-dead eggs during trials.
The players
Zoetis
Zoetis is a global animal health company that provides medicines, vaccines, and diagnostic products for livestock and companion animals.
The details
In ovo vaccination is a process that delivers treatments to embryos at 18 days and 12 hours of incubation, requiring precise targeting of the amnion or embryo. The study found that competing devices failed to deliver vaccines to between 14% and 22.6% of processed embryos.
Timeline
Comparative vaccination trials were conducted in 2025.
The trials occurred during the 18 days and 12 hours of incubation phase.
Culture Shift
This study aligns with the historical industry focus on hatchery vaccination efficiency standards by introducing refined performance metrics. These findings reflect a shift toward data-driven equipment selection to maximize biological yield and resource efficiency.
These findings directly influence the operational efficiency and overhead costs of poultry hatcheries. Producers can use these performance benchmarks to guide equipment procurement and improve the overall vaccination success of their batches.
The takeaway
Optimizing site-of-injection accuracy is a vital step for any producer looking to minimize vaccine waste and improve chick health. By selecting systems that effectively differentiate between viable and nonviable eggs, hatcheries can significantly improve their operational success rates.
