Five experiments utilizing 3,628 pigs
were conducted to determine the true ileal digestible
(TID) Lysine requirement for 11- to 27-kg pigs fed corn soybean
meal diets. Data from
all 5 experiments yielded a single-slope, broken-line
response, with requirement estimates for TID Lys of
1.33 and 1.35% for 11- to 19-kg pigs. The 5 experiments
gave requirement estimates of 1.30% TID Lys (3.80 g
of TID Lys/Mcal of ME) for 11- to 27-kg pigs, equivalent
to 19 g of TID Lys/kg of gain.
