Linear and quadratic broken line regression analysis for the standardized ileal digestible (SID) Trp:Lys ratio on lactating primiparous and multiparous sow ADFI. The BIC for the linear model (red line) was 2,994 with an estimate of the ratio at 14.0 and the BIC value for the quadratic analysis (green line) was 2,986 with the ratio estimate of 17.6.

Linear and quadratic broken line regression analysis for the standardized ileal digestible (SID) Trp:Lys ratio response of primiparous and multiparous sows fed different SID Trp:Lys ratios on wean to estrus interval (WEI). The linear regression (red line) BIC value was 1404 with the SID Trp:Lys ratio estimate of 15.3 and the quadratic regression (green line) BIC value was 1401 with an estimated ratio of 17.2.
