Research theme
Demonstration development for mass production of oral vaccine/feed additive for swine
Business Plan
This project aims to establish scalable manufacturing processes suitable for the mass production of a silkworm-derived oral vaccine ingredient for pigs.
The target product, developed using a proprietary recombinant protein expression system in silkworms, has been registered and launched in Vietnam as a “feed additive.”
To ensure stable commercial supply, the project focuses on building production readiness for scale-up. The resulting manufacturing technology is also intended for future application in domestic distribution within Japan.
Research Outline
This project aims to establish a mass production platform capable of enabling large-scale and stable supply of the target product, which demonstrated market demand during the PCA phase.
To achieve this objective, the following R&D components will be pursued:
- Establishment of mass production base technology
- Scale-up of production capacity through automation
- Reduction of production costs
- Implementation of quality control and regulatory compliance measures
