“…Plasma concentrations of cortisol are usually increased at parturition (Smith et al, 1973;Hudson et al, 1976). An increase in concentrations of cortisol in plasma of cows at parturition was probably not detected in the present experiments because cows were only sampled once a day or stress of sampling influenced secretion of cortisol.…”

Fall-calving Angus cows were used to evaluate the effect of ambient temperature on duration of gestation. In Exp. 1, cows were AI and calved in August (n = 14) or October (n = 10). Cows grazed native prairie pasture in Oklahoma and had a BCS of 6.0 ± 0.5 (1 = emaciated, and 9 = obese) at parturition. Commencing 2 wk before the expected calving date, blood samples were taken from the coccygeal vein every 2 to 3 d until calving. Cows that calved in August tended to have shorter gestations (P = 0.07) compared with cows that calved in October. Maximum daily ambient temperature during the last 14 d of gestation was greater for August-calving cows (P < 0.001) compared with October cows. Concentrations of cortisol in plasma during the last 4 d of gestation were greater in cows that calved in August (P < 0.04) compared with cows that calved in October. In Exp. 2, cows were AI and calved in either mid-August (n = 7), late-August (n = 6), September (n = 6), or October (n = 8) to evaluate the effects of elevated ambient temperature on duration of gestation, ruminal temperature at parturition, and plasma cortisol, progesterone, and estradiol. Temperature boluses (SmartStock, LLC, Pawnee, OK) programmed to transmit temperature every hour were place in the rumen at 255 d of gestation. Cows grazed native prairie pasture in Oklahoma and had a BCS of 6.5 ± 0.4 at calving. Maximum ambient temperatures during d 263 to 273 of gestation were influenced by month of calving × day (P < 0.001). Duration of gestation was shorter for mid-August cows (P < 0.05) compared with October cows, but did not differ compared with late-August (P = 0.29) and September (P = 0.50) cows. Ruminal temperature during the 4 d before calving was not influenced by month of calving (P = 0.76). Ruminal temperature was decreased during the 24 h before parturition for cows in all months (P < 0.01) compared with 2 to 4 d before parturition. Concentrations of cortisol in plasma during d 271 to 276 of gestation were less (P < 0.05) for late-August compared with cows that calved during the other months. Concentrations of progesterone were greater during 7 d before parturition in October compared with cows that calved in September. Estradiol in plasma of cows during late gestation was not affected by month of calving (P = 0.76). Exposure of beef cows to elevated ambient temperature resulted in shorter gestations. Ruminal temperature in cows decreased ≥ 0.3°C the day before parturition.

Parturition was induced in 12 dairy heifers with prostaglandin (PG) F2 alpha about 2 weeks before the expected time of calving. Eight animals gave birth after two injections (group 1), three animals needed more than two injections (group 2) and one animal (cow no. 740) required one injection. All animals in groups 1 and 2 had retained foetal membranes and the time needed to induce parturition was 59 +/- 7 and 149 +/- 10 h, respectively. As cow no. 740 did not have retained foetal membranes and calved 24 h after one PGF2 alpha injection, it was excluded from the results. Udder distension and relaxation of the pelvic ligaments could predict the calving to within 12 h. Furthermore, the pre-calving drop of body temperature could predict the time of parturition to within 16 h. The total white blood cells and polymorphonuclear cells were at their highest values on the day preceding parturition whereas mononuclear cells had a tendency to increase 3 days after calving. Increased levels of haemoglobin were found at the time of parturition, whereas, plasma-calcium levels significantly decreased after parturition (P < 0.001). Progesterone levels markedly decreased after the first PGF2 alpha injection and reached 2 nmol/l at the time of parturition. Plasma levels of oestradiol-17 beta reached the peak at the time of parturition, whereas, the highest levels of the PGF2 alpha metabolite and cortisol were recorded 16 h after calving.

“…In this study, an effect of parity on hair cortisol concentration was observed only in samples collected before parturition (L0), and not in those from the lactation period. Since the HPA axis has a crucial role in initiating parturition, the plasma cortisol concentration peaks at parturition and returns to the basal concentration by 3 days postpartum (Hudson, Mullford, Whittlestone, & Payne, 1976). Since the HPA axis has a crucial role in initiating parturition, the plasma cortisol concentration peaks at parturition and returns to the basal concentration by 3 days postpartum (Hudson, Mullford, Whittlestone, & Payne, 1976).…”

The objective of this study was to investigate the profiles of hair cortisol concentrations as an index of chronic stress in dairy cows in association with their health, nutrition, and reproductive parameters. For 25 Holstein dairy cows, hair was collected from the tail switch −19.2 ± 11.4, 44.8 ± 11.9, 103.0 ± 9.9, and 168.0 ± 9.7 days postpartum (L0, L1, L2, and L3, respectively). Body condition scores were negatively correlated with hair cortisol concentrations (r = −0.255), and hock health scores were positively correlated with hair cortisol concentrations (r = 0.236, p < 0.05). Hair cortisol concentrations during the postpartum period showed different patterns according to the time of first artificial insemination (AI) and fertility. Cows that were submitted to first AI by 86 days postpartum showed a peak hair cortisol concentration at L1, whereas cows with delayed first AI had a peak at L2. The hair cortisol concentrations of subfertile (≥168 days) cows were significantly higher at L1 and L2 compared with L0, whereas hair cortisol concentrations of fertile cows (<168 days) were not different among the sampling times. These results indicate that cows with health problems appear to experience greater chronic stress, which may impair their reproductive function.
