“…In dairy cattle, mastitis is a major cause of biological inefficiency or waste, for example, through lower yields, increased culling, discarded milk and impacts on fertility (Halasa et al, 2007;Seegers, Fourichon, & Beaudeau, 2003). In addition, mastitis affects animal welfare, which is highly valued in many industrialized countries (Byrd, Widmar, & Fulton, 2017;Tremetsberger, Leeb, & Winckler, 2015). Thus, there are many reasons to control mastitis in dairy cattle.…”
