Item	Treatment ¹			SEM	p Value
Item	Control	Zn-Met	ZnO	SEM	p Value
Alkaline phosphatase, ng/mL Metallothionein, pg/mL	1.55 ^b 768 ^b	1.74 ^a	1.73 ^a	0.05	0.034

^a,b Mean values in the same row with different superscripts are significantly different (p < 0.05). ¹ Treatment: CON (control), fed only milk and starter diet; Zn-Met group, fed milk and starter diet containing 455 mg Zn-Met (equivalent to 80 mg zinc); ZnO group, fed milk and starter diet containing 103 mg zinc oxide (equivalent to 80 mg zinc).
