Volcano plot displaying differentially expressed proteins of day 1 vs. day 4 (a), day 1 vs. day 7 (b), and day 1 vs. day 15 (c). The y-axis corresponded to the mean abundance value log10 (P value/significance), and the x-axis displayed the log2 fold change value. The red and blue dots represent the significant differentially expressed proteins (P < 0.05) in buffalo milk somatic cells. The grey dots represent the proteins whose abundance level did not reach statistical significance during the respective days.
