文摘
- •
Portable XRF can detect feed and fecal marker concentrations with up to 100% accuracy.
- •
Results are repeatable.
- •
Dry matter digestibility determined by silica concentration same as total fecal collection.
- •
Reduced potential of analytical error due to removal of acid digestion prior to analysis.
- •
Portable XRF may provide greater accuracy with reduced cost and time compared to ICP.
