Figure 4

Fitted broken-line plot of ATTD of calcium as a function of dietary phytase level in growing pigs (Exp. 2) with observed treatment mean values (n = 8 observations per treatment mean). The minimal dietary phytase level determined by broken-line analysis using least squares methodology was 574 FYT/kg (Y plateau = 83.5; slope below breakpoint = −0.0283; Adjusted R2 = 0.958).
