Changes of plasma fibronectin and fibronectin-fibrin complexes in dams of stillborn dairy calves

Table 1 Fibronectin and fibrinogen concentrations in maternal plasma in relation to perinatal mortality of calves

Parameter	Mean ± SD median (25th–75th percentile) values of concentration in the plasma groups:
Parameter	DSBa n = 47	DSBn n = 45	DC n = 21	LC n = 14
FN mg/L	40.0 ± 17.5	47.5 ± 20.5	57.5 ± 13.1	71.7 ± 15.2
FN mg/L	34.7 (23.9–55.4)^A	45.2 (29.4–63.5)^AC	59.2 (51.7–64.2)^BC	74.1 (62.3–83.0)^B
Fb g/L	4.9 ± 1.7	4.9 ± 1.5	4.9 ± 1.5	3.6 ± 1.1
Fb g/L	5.1 (3.7–5.9)^a	4.9 (3.7–5.9)^a	4.3 (3.7–6.2)	3.4 (2.9–3.9)^b

A, B, C, D – values in rows with different letters differ significantly P < 0.01.
a, b, c, d– as above for P < 0.05.
DSBa – dams of singleton stillborn calves which internal organs showed significant autolytic changes, DSBn – dams of singleton stillborn calves without or with negligible autolytic changes in internal organs, DC – dams of live-born calves, LC – cows during mid to late lactation.
