Estimation of leucine requirement for weaned piglets. Prediction of the average daily gain (ADG) according to the standardized ileal digestible (SID) leucine to lysine dietary content with a linear quadratic model. Observed values (o) from d7 to end (d28). Equation of prediction (parameters ± S.E.): Y = −1061 (±285) + 29.46 (±5.89)*X – 0.133 (±0.029)*X2. Adjusted R2 = 0.334; Root mean square error (RMSE) = 96. For all the parameters, P < 0.0001. Estimated maximum ADG at 570 g with 110.7% SID leucine to lysine.
