Effect of TFRD on AFB1-induced breast muscle color parameters in broilers. (A) Schematic diagram of experimental design to study the effect of TFRD on AFB1-induced breast muscle injury in broilers. (B) Representative color images of breast muscle in the CON, TFRD, AFB1, and AFB1 + TFRD groups were observed during the entire experimental period. (C,D) Relative changes in breast muscle and breast muscle ratios were recorded and analyzed over the entire experimental period. (E) The color [lightness (L*), redness (a*), and yellowness (b*)] of the breast muscles in the CON, TFRD, AFB1, and AFB1 + TFRD groups were measured and analyzed. Different letters indicate statistically significant differences (p < 0.05), and all values are presented as the means ± SD, one-way ANOVA.
