Table 1. Food intakes of the maternal and young rats in different groups.

		Food intake, g/day
	AGA	NCUG-SGA	CUG-SGA
Maternal rats	20.97±3.14	18.36±2.23	20.08±2.52
Young rats at 4 weeks of age
Males(n = 31,36,and 34)	9.43±1.95	8.53±2.17	10.04±2.33
Females(n = 25,33,and 20)	8.75±1.81	8.24±1.96	9.27±2.15

The numbers of rats in the maternal appropriate for gestational age (AGA), small for gestational age with catch-up growth (CUG-SGA) and small for gestational age with no catch-up growth (NCUG-SGA) groups were 15, 20 and 20, respectively. Young rats at 4 weeks: n = 56 in AGA group, n = 54 in CUG-SGA group, n = 69 in NCUG-SGA group. There are not significant differences in AGA, CUG-SGA and NCUG-SGA groups. Food intakes of young male rats in different groups were comparable to those of females respectively.
