parturition induction

is a common management practice in dairy herds in order to synchronize calvings and lactations. It is also used for therapeutic reasons when large fetuses are expected or in sows when mastitis-metritis-agalactia is a problem in the herd. The usual method is the injection of a suitable corticosteroid, oxytocin or PGF_2a. Undesirable side-effects include high calf mortality rate, retained placenta, photosensitive dermatitis and unusual metabolic diseases. Called also calving induction. Called also parturition initiation.
