  1. 1The metabolizable energy content of corn, soybean meal and wheat bran were determined previously in our laboratory (data not published). Metabolizable energy of soybean oil (calculated as 96% of DE) was obtained from Feeding Standard of Swine [2].
  2. 2Standardized ileal digestible lysine was determined previously using pigs surgically equipped with a T-cannula in the distal ileum. The basal ileal endogenous losses were measured by feeding a nitrogen-free diet (data not published).
