“It is worth noting that a recent analysis from the Organic Center (Benbrook, 2009), intended to demonstrate the advantages of moving from conventional to organic dairy production, is based on a flawed premise, namely that productivity (milk yield per cow) does not differ between conventional and organic systems. Productivity
is demonstrably lower under organic management with a reduction in milk yield per cow ranging from 15-27% (Nauta et al., 2006; Sato et al., 2005; USDA, 2007; Zwald et al., 2004). When differences in productivity are accounted for, organic dairy production requires considerably more resources (feed, land, water etc) per unit of milk produced and has a greater environmental impact (Capper et al., 2008).”
