¹n = 3: there were three replicates per treatment and twelve neonatal piglets per replicates.

²Con: the control group diet used the basal diet.

³LF1: the LF1group diet supplemented with 100 mg LF/kg in the basal diet.

⁴LF2: the LF2group diet supplemented with 200 mg LF/kg in the basal diet.

⁵LF3: the LF3group diet supplemented with 300 mg LF/kg in the basal diet.

⁶Fe-Gly: the Fe-Gly group diet supplemented with 100 mg Fe/kg from ferric-glycine complex in the basal diet.

⁷Results are presented as mean ± SEM.

^abWithin a row, values with different letter superscripts differ significantly (P < 0.05).
