Table 4. Three days calcium intake, fecal calcium excretion and apparent absorption.

Group	Calcium intake(mmol/3d)	Fecal calcium excretion(mmol/3d)	Apparent absorption1)(mmol/3d)	Apparent absorption rate2) (%)
Low sn-2 PA	6.25 ± 0.56	3.58 ± 0.41a	2.65 ± 0.44a	42.6 ± 5.3a
Medium sn-2 PA	6.45 ± 0.50	3.03 ± 0.33b	3.43 ± 0.61b	53.8 ± 6.8b
High sn-2 PA	6.35 ± 0.24	2.48 ± 0.44c	3.88 ± 0.44b,c	61.0 ± 6.8c

The results are the mean ± SD of 12 animals per group.

^a,b,c Mean values within a column with unlike superscript letters were significantly different (P< 0.05; ANOVA followed by post hoc Tukey’s multiple comparison test).

¹⁾ Apparent absorption (mmol) = Calcium intake (mmol)–fecal Calcium excretion (mmol)

²⁾ Apparent absorption rate (%) = [Apparent absorption (mmol)/Intake (mmol)] ×100
