Plasma cortisol concentrations in Holstein Friesian and Belgian Blue newborn calves born by different types of delivery
L. O. Fiems, M. C. Veronesi, Geert Opsomer, Tanja Peric, M. Montillo, M. Probo, 2016, published scientific conference contribution abstract

Abstract: Cortisol (C) is a major stimulus for fetal and neonatal lung maturation and for surfactant production. Neonatal calves born by caesarean section (CS), particularly the double-muscled Belgian Blue (BB), are more proned to develop the respiratory distress syndrome (Cambier et al. 2002 Vet Res 33, 283–290; Danlois et al. 2003 Vet J 165, 65–72). The aim of this study was to investigate C plasma levels in 15 Holstein Friesian (HF) newborn calves born by spontaneous vaginal delivery (VD) and in 25 BB newborn calves born by elective CS. Blood samples were taken at 10, 20, 30 min and at 6, 24 h after birth and at 7 and 14 days of age. Plasma C concentrations were analyzed by RIA. Statistical analysis evidenced an influence of both time (p < 0.05) and group (p < 0.0001) on C concentrations. In agreement with previous studies, high C levels at birth were followed by a reduction at 6 h and by a further decrease on day 7 after birth in both groups. Cortisol concentrations were different between BB and HF calves, with significantly higher levels in HF calves. These findings are in agreement with studies in newborn babies, while previous studies on calves mentioned no differences in C levels between calves born without assistance vs. calves born by CS. The present results suggest that both breed and type of delivery are associated with plasma C levels in the newborn calf.

Maternal and fetal hair cortisol concentrations in beef cattle at delivery
Alberto Prandi, Marta Montillo, Maria Cristina Veronesi, Monica Probo, Antonella Comin, Tanja Peric, 2018, published scientific conference contribution abstract

Abstract: Hypothalamus-pituitary-adrenal (HPA) axis of both mother and fetus, is one of key mechanisms involved in fetal programming. Cortisol, the end-product of this axis, plays a critical role in regulating fetal and new-born metabolism and development. The aim of the study was to evaluate maternal and fetal cortisol concentrations shortly after delivery on hair samples non-invasively collected. The study was carried out on 11 pairs of beef cows and their calves (calves were 12 because of one case of twins) from the same farm and subjected to the same managerial conditions. Hair from new-born calves and from their mothers was collected on the day of birth shaving their withers to the level of the skin. The hair cortisol concentrations (HCC) were determined by RIA as previously described (Peric et al. 2013: J Dairy Sci 96:3023–3027). The results showed that fetal and maternal HCC ranged from 16.11 to 40.43 pg/mg and from 1.88 to 15.73 pg/mg respectively, with fetal and maternal mean ± SE HCC of 23.72 ± 2.21 and 6.40 ± 1.32 pg/mg respectively (p < 0.001). Fetal HCC were on average 3.5 higher than those of mothers but this ratio differed among the pairs. These differences were also found among the twin calves. These results indicate that in beef cows-and-calves pairs, although HCC at delivery were always higher in calves than in cows, the ratio between fetal and maternal HCC differs among pairs, suggesting an individuality in the fetal programming processes that may also rely on genetic and epigenetic factors.
