Fitted broken-line linear (BLL) and broken-line quadratic (BLQ) regression models on G:F as a function of increasing standardized ileal digestible (SID) Trp:Lys in 11- to 20-kg pigs (Exp. 2.). The maximum G:F was estimated at 16.6% (95% confidence interval [CI]: [16.0%, 17.3%]) and 17.1% (95% CI: [16.6%, 17.7%]) SID Trp:Lys in the BLL and BLQ models, respectively.
