Fitted broken-line linear (BLL) regression model on feed efficiency (G:F) as a function of increasing standardized total tract digestible (STTD) P with 1,000 added phytase units in 11- to 23-kg pigs in Exp. 2. The BLL breakpoint was estimated at 0.37% (95% CI: [0.29, 0.45]%). Based on the best fitting model, the estimated regression equation was G:F, g/kg = 711.76 − 301.08 × (0.37 − STTD P) if STTD P < 0.37%, and G:F, g/kg = 711.76 if STTD P ≥ 0.37%.
