Fig. 1From: Optimal dietary standardized ileal digestible lysine level for pigs during the grower, early and late finisher periodsEstimation of SID Lys for 30 to 60 kg growing pigs (Exp. 1). Data points represent treatment means. Fitted broken-line (a) and quadratic (b) plot of F:G as a function. The optimal Lys requirement determined by broken-line analysis was 0.88 (y plateau = 2.05, R2 = 0.80), and by quadratic analysis was 0.99 (y plateau = 2.01, R2 = 0.92)Back to article page
