Table 3. Number and percentage of primiparous and multiparous cows based on calcium status in the first 3 days after calving.

Calcium status	Parity
	Primiparous (n = 122)	Multiparous (n = 149)
Control1	28 (22.95)	22 (14/76)
Transient subclinical hypocalcaemia (TSCH)2	82 (67.21)	37 (24/83)
Persistent subclinical hypocalcaemia (PSCH)3	12 (9.83 )	90 (60/40)

(1): Serum calcium concentration >8.5 mg/dl at calving day, 1 and 2 postpartum; (2): Serum calcium concentration ≥8.5 mg/dl on calving day and 1 or 2 postpartum; (3): Serum calcium concentration ≤8.5 mg/dl on calving day, 1 and 2 postpartum.
