Summary
A new modular assay, Feed-code, was developed for analyzing feed botanical composition, detecting impurities, and ensuring feed safety. This method offers more reliable results than traditional analysis for feed ingredient authentication.
Area of Science:
- Agricultural Science
- Food Science
- Analytical Chemistry
Background:
- Feed composition analysis is crucial for detecting economic fraud and ensuring feed safety, as mandated by Regulation (EC) 767/2009.
- Accurate identification of feed ingredients is essential for regulatory compliance and quality control in the animal feed industry.
Purpose of the Study:
- To develop and validate a modular assay for the qualitative and quantitative analysis of botanical feed composition.
- To assess the performance parameters of the assay, including applicability, repeatability, specificity, and limit of detection.
- To evaluate the assay's effectiveness in identifying botanical impurities in compound feeds and raw materials.
Main Methods:
- Development of a modular assay based on intron polymorphism for botanical composition analysis.
- Internal validation of the assay, evaluating key performance parameters.
- Application of the assay to feed-like samples, compound feeds, and raw materials.
- Comparison of results with traditional microscopic analysis.
Main Results:
- The developed Feed-code assay successfully performed qualitative and quantitative analysis of botanical feed composition.
- The assay demonstrated good performance in terms of applicability, repeatability, and specificity.
- Application revealed the presence of botanical impurities in various feed samples.
- The Feed-code method provided more reliable results compared to microscopic analysis.
Conclusions:
- The Feed-code prototype is a reliable tool for the authentication of feed botanical composition.
- The modular design allows for future upgrades to include additional plant species.
- The assay warrants further validation through a collaborative trial for widespread adoption.
