Scientific illustration comparing lab analysis and portable NIRS for feed composition, with various statistical plots and component icons.

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
