“…Relaxation of the Broad Pelvic Ligaments and Teat Filling. In addition to SIP, we examined relaxation of the pelvic ligaments and teat filling because these findings had the best predictive value for predicting calving within 12 h (Streyl et al, 2011). At 0800 and 2000 h, heifers were fixed in the head lockers for approximately 10 min.…”

“…As a result of hormonal changes in preparation for calving, the broad pelvic ligaments relax, the udder enlarges, and teats fill up with colostrum (Berglund et al, 1987;Shah et al, 2006;Streyl et al, 2011). Monitoring cows antepartum is possible via direct observation, video surveillance, or the application of technical devices such as accelerometers (e.g., Ouellet et al, 2016), rumination sensors (e.g., Pahl et al, 2014), and temperature loggers (e.g., Burfeind et al, 2011).…”

The clinical signs (i.e., relaxation of the broad pelvic ligaments, vaginal secretion, udder hyperplasia, udder edema, teat filling, tail relaxation, and vulva edema) alone and combined were evaluated to predict the time of parturition (Streyl et al, 2011). According to Streyl et al (2011), the relaxation of the broad pelvic ligaments in combination with teat filling gave the best values for predicting either calving or no calving within 12 h, with a sensitivity ranging from 73.9 to 89.1 and a specificity ranging from 60.0 to 78.9 depending on the cut-off value.…”

Ouellet et al (2016) used 3 automated devices to measure vaginal temperature, rumination and lying time, and lying bouts to predict the onset of calving.…”

The objective of this study was to predict stage 2 of calving in Holstein-Friesian heifers. Interobserver reliability and predictive values of relevant signs of imminent parturition (i.e., tail raising, stepping, clear and bloody vaginal discharge, turning the head toward the abdomen, and lying lateral with abdominal contractions) were determined. In the first experiment 32 heifers were included. Three investigators participated as observers in the study. They walked through the precalving pen in pairs and observed pregnant heifers (≥267 d pregnant). Cohen's kappa results for the interobserver reliability were between 0.51 and 0.91. Thirty-seven Holstein-Friesian heifers were enrolled in the second experiment. Heifers were observed hourly for 24 h/d. Signs of imminent parturition that occurred were noted on a checklist. Compared with a precalving control period (4 d before calving), tail raising, clear vaginal discharge, and bloody vaginal discharge were more likely to occur during the last 24 h before calving. Two equations were built using the GENLINMIXED procedure to predict the hours until parturition. In version 1, the absence or presence of each sign of imminent parturition except turning the head toward the abdomen was included. In version 2, hours until parturition were estimated with the factors days of gestation, tail raising, and clear vaginal discharge. Relaxation of the broad pelvic ligaments and teat filling were evaluated twice per day. Prediction of calving with these parameters was not satisfying (positive predictive values were between 35.1 and 72.7% depending on the day of gestation). The possibility of excluding calving for the next 12 h was considerably higher, ranging from 88.5 to 97.1%. These results indicate that predicting stage 2 of calving via direct observation of plausible signs is imprecise and therefore not recommendable.

“…The calving event itself is announced by typical behavior patterns of cows in the first stage of labor (Wehrend et al, 2006). Streyl et al (2011) found that, among physiological indicators, the combination of relaxation of ligaments and filling of teats delivered the best results for improvement of calving prediction.…”

Monitoring rumination behavior serves multiple purposes in feeding and herd management of dairy cows. The process of calving is a major event for cows, and a detailed understanding of alterations in behavioral patterns of animals in the time around calving is important in calving detection. The objective of this study was to describe the short-term changes in rumination patterns in dairy cows immediately before and after parturition. In total, 17 cows were fitted with rumination sensors that were able to monitor rumination time, number of rumination boli, and number of rumination jaw movements. Rumination time was decreased in the last 4h antepartum and in the first 8h postpartum. Cows stopped ruminating 123 ± 58 min (mean ± standard deviation) before calving and resumed ruminating 355 ± 194 min after calving. The number of rumination jaw movements and boli per day were decreased in the 24-h period postpartum. Rumination rate, the number of rumination jaw movements per rumination minute, and the number of boli per rumination minute changed little around calving. The calving event primarily influenced the duration and frequency of various rumination characteristics but not rumination intensity. Among detected characteristics, rumination time showed the greatest potential for monitoring of calving events.

Background: With unique genetic traits, Hanwoo cattle (Bos taurus coreanae) are welladapted to the Korean environment. However, their perinatal mortality rate is 2%-3%, which imposes an economic burden.Objective: Due to insufficient data on hormonal changes around parturition, the timing of parturition is often predicted subjectively; few studies have examined hormones in Hanwoo cattle. We measured the changes in various hormones around parturition, to seek an objective predictor of parturition time. Methods:In 14 female Hanwoo cattle, we measured progesterone, prolactin and cortisol concentrations daily in jugular vein blood samples, beginning 6 days before parturition until 7 days after parturition. Conception was induced in five animals using artificial insemination. Nine animals received embryo transfer.Results: During parturition, the concentration of progesterone decreased significantly in the embryo transfer group (n = 9) and in the total population (n = 14); it did not change significantly in the artificial insemination group (n = 5). Prolactin concentration increased on the day of parturition but did not differ significantly among the groups.Cortisol remained constant throughout the study course. Conclusion:We concluded that parturition time can be predicted in Hanwoo cattle using progesterone concentration. This knowledge can reduce perinatal mortality, which would help to improve farm income and animal welfare.
