State of the art in feedstuff analysis: a technique-oriented perspective

Area of Science:

• Agricultural Science
• Analytical Chemistry
• Food Science

Background:

• Global feed supply chains necessitate robust traceability and stringent quality control.
• The feed industry faces high-throughput testing demands driven by regulatory enforcement and safety concerns.
• Evaluating feed quality, safety, and functional properties requires a complex, multianalytical approach.

Purpose of the Study:

• To review current and emerging analytical methods for feed analysis.
• To assess the potential and limitations of various feed characterization techniques.
• To identify challenges in developing validated and standardized methods for global feed evaluation.

Main Methods:

• Classical chemical analysis.
• In situ and in vitro methods.
• Analytical techniques coupled with chemometric tools (NIR, sensors) and cell-based bioassays.

Main Results:

• Classical methods provide foundational analysis, while newer techniques offer speed, sensitivity, and cost-effectiveness for high-volume testing.
• Spectroscopic methods (NIR) and sensor technologies, when combined with chemometrics, show promise for rapid compositional and functional property assessment.
• Cell-based bioassays offer a complementary approach for evaluating functional properties and safety, though standardization remains a challenge.

Conclusions:

• A multianalytical strategy integrating diverse methods is essential for comprehensive feed evaluation.
• Further research and validation are needed to standardize novel analytical techniques for routine global application.
• Addressing limitations in current methods will enhance feed quality, safety, and traceability worldwide.
