Additional work should expand the scope of research to include other putative mammary health biomarkers (e.g., interleukin-8, transforming growth factor-β [TGF-β], lactose, lactoferrin, and lactate dehydrogenase) as well as examine composite measures of biomarkers (akin to Na/K ratios) for improving the prediction and/or use in the prevention of future mastitis. Here, TGFB1 is linked to mastitis.
