But organic farms have overall lower milk yields (on average 24 % lower) than conventional farms (table 1). The productive life of cows on organic farms (on average 3.3 years) was one year longer than on conventional farms (table 1). Figure 1 B shows the positive correlation between lifetime efficiency and milk yield in both farming systems (p
