The experiment was conducted to determine the apparent
ileal digestibility (AID) and standardized ileal
digestibility (SID) of N and AA, and the standardized
ileal digestible AA contents of EECM fed to growing
pigs. Six barrows with an average BW of 26.8 ± 1.3
kg were used in this experiment. Pigs were housed individually
in pens (1.5 × 1.2 m) with smooth sides
and plastic-covered expanded metal flooring in a temperature-
controlled room (22 ± 2°C). Pigs had been
surgically fitted with a T-cannula at the distal ileum as
described by Nyachoti et al. (2002).
The experimental diets included a corn starch-based
diet with either SECM or EECM as the sole source of
protein, and a casein- and corn starch-based diet
