Data are means or means ± standard errors of eight animals.
Derived from the preplanned contrast except for days 0 and 28 body weights (BW) and ADG which were derived from t test.
Barrows fed the medium-lysine (0.80%) diet, gilts fed the medium-lysine diet, and gilts fed the low-lysine (0.60%) diet, respectively.
T1 and T2 were not measured. Average daily feed intakes for T3 and T4 were 3.23 and 2.87 kg, respectively, during the first 28days and 3.60 and 3.44 kg, respectively, during the subsequent period to slaughter.
Days 67 and 74 were when final weights (SW) for T3 and T4, respectively, were measured.
Corrected for 116- and 150-kg final weights for the AV- and XH-SW groups, respectively.
T, treatment; B-Med, barrow-medium; G-Med, gilt-medium; BW, body weight; D, day; ADG, average daily gain.
