Caesarean Section An operation in which the fetus is delivered by means of an incision through the wall of the abdomen and uterus. It is chiefly performed in bitches sows cows and ewes occasionally in the mare when the pelvic passage is for some reason unable to accommodate and discharge the fetus when the fetus has become jammed in such a position that it cannot pass through the pelvis and its delivery cannot be effected when the value of the progeny is greater than the value of the dam and when the dam is in extremis and it is believed that the young is or are still alive. In this latter case the dam is usually killed and the abdomen and uterus are opened at once. There is a possibility of saving the fetus in the mare and the cow by this method provided that not more than 2 minutes elapse between the time when the dam ceases to breathe and when the young animal commences.
