Process of bringing forth a child from the uterus, ending pregnancy. It has three stages. In dilation, uterine contractions lasting about 40 seconds begin 20 – 30 minutes apart and progress to severe labour pains about every 3 minutes. The opening of the cervix widens as contractions push the fetus. Dilation averages 13 – 14 hours in first-time mothers, less if a woman has had previous babies. When the cervix dilates fully, expulsion begins. The "water" (amniotic sac) breaks (if it has not already), and the woman may actively push. Expulsion lasts 1 – 2 hours or less. Normally, the baby's head emerges first; other positions make birth more difficult and risky. In the third stage, the placenta is expelled, usually within 15 minutes. Within six to eight weeks, the mother's reproductive system returns to nearly the prepregnancy state. See also cesarean section; lactation; midwifery; miscarriage; natural childbirth; obstetrics and gynecology; premature birth.

  • p. acceleration — used most commonly in sows with uterine inertia; usual medication is oxytocin; carazolol a recent introduction to the list.
  • p. delaying — attempted to give more time for relaxation of the cervix; clenbuterol the common medication.
  • difficult p. — see dystocia.
  • p. 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. Undesirable side-effects include high calf mortality rate, retained placenta, photosensitive dermatitis and unusual metabolic diseases. Called also calving induction. Called also parturition initiation.
  • p. initiation — see parturition induction (above).
  • p. injury — includes laceration of the cervix, vaginal wall or vulva, uterine rupture, fat hernia through the vaginal wall, uterine prolapse, rupture of middle uterine artery, sciatic nerve injury, maternal obstetric paralysis.
  • prolonged p. — prolongation of parturition beyond the normal for the species is attended by risks to the dam and the fetuses.
  • p. psychosis — see farrowing hysteria.
  • synchronized p. — control of the date of parturition by controlling the date of estrus and of mating, or by the induction of parturition.
  • p. syndrome — a loose diagnosis embracing many toxemias that occur about the time of calving. See acetonemia, fat cow syndrome, pregnancy toxemia, mastitis, metritis and peritonitis.
