Valine is among the limiting AA in low protein diets for pigs, but data are currently lacking for empirical requirement studies. Therefore, 2 growth assays and 1 N-balance trial were conducted to determine the Val requirement of weaned pigs (8 to 25 kg of BW) expressed as the ratio of standardized ileal digestible (SID) Val to Lys. In Exp. 1, 48 pigs (individual housing; equal proportion of castrates and females; initial BW = 8.0 kg) were randomly subdivided into groups receiving 6 dietary… CONTINUE READING
