Scientific graphical abstract illustrating the comparison of portable NIRS devices and laboratory (LAB) analysis for buffalo feed (TMR) composition. Show two portable NIRS devices scanning feed samples, alongside a lab setup with chemical analysis equipment. Include icons or small diagrams representing the main feed components: DM (dry matter), EE (ether extract), ash, CP (crude protein), aNDFom, ADF, ADL, starch. Visualize statistical analyses: Bland-Altman plots, Passing-Bablok regression (bias correction arrows showing improved agreement), and PCA clusters. Highlight that DM and EE predictions closely match LAB after correction, while fiber fractions still show discrepancies. Style: clear, professional, colorful, scientific illustration suitable for a journal graphical abstract Mehr sehen
