► Hp is over-expressed in clinical mastitis vs. control. ► ApoA-I is down-expressed in clinical mastitis vs. control. ► Serpin A3-1 and vitronectin are up-regulated in subclinical mastitis vs. control. ► Complement factor H is down-regulated in subclinical mastitis vs. control. ► Vitronectin could be a possible marker for subclinical mastitis.
