Table 4. Apparent total tract retention (ATTR) of energy in brown rice fed to laying hens, DM basis¹⁾

Item	Mean	SD
ATTR of GE of diet (%)	86.0	2.29
AME of the brown rice (kcal/kg)	3,773	100.4
Retained N (g/kg Intake)	5.4	1.56
AMEn of the brown rice (kcal/kg)	3,729	90.7

Values are means of six replicate cages with three hens per cage.
DM, dry matter; SD, standard deviation; GE, gross energy; AME, apparent metabolizable energy; AMEn, nitrogen-corrected AME.
