Predicting of the calving is of critical value as it enables the rescue of new born calve. In dairy herds, it may be difficult to monitor individual animal in the pre partum period. Several findings such as the decrease of rectal or vaginal temperatures, blood progesterone and mammary electrolyte levels were proposed in order to predict the onset of parturition. The study has been carried out on 17 heifers and 15 Holstein cows. Upon observation of signs of approaching parturition the C6 birth control® device was applied just upon the ventral commissure of the vulva. At the onset of parturition the obstetric examination was carried out in order to determine the extent of cervical dilation, foetal presentation, position and posture. Length of parturition time from alarm activation to complete foetal expulsion was recorded.

Abstract
Predicting of the calving is of critical value as it enables the rescue of new born calve. In dairy herds, it may be difficult to monitor individual animal in the pre partum period. Several findings such as the decrease of rectal or vaginal temperatures, blood progesterone and mammary electrolyte levels were proposed in order to predict the onset of parturition. The study has been carried out on 17 heifers and 15 Holstein cows. Upon observation of signs of approaching parturition the C6 birth control® device was applied just upon the ventral commissure of the vulva. At the onset of parturition the obstetric examination was carried out in order to determine the extent of cervical dilation, foetal presentation, position and posture. Length of parturition time from alarm activation to complete foetal expulsion was recorded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
