The contractions of the womb are very powerful, andare analogous to that of the intestines—extending fromthe extremity of the horn towards the neck with worm-like muscular contractions, particularly in these animalswhich, like the Bitch and Pig, have very long horns, withthe young arranged one after another in them. (Fig. 10-A.) The contractility of the womb, which signifies alsoits retractility, enables it to contract on itself after deliv-ery, and to nearly obliterate its cavity. This rapid dim-inution in the capacity of the organ closes the orifices ofthe vessels which open on the internal surface of the wombduring the act, and thus prevents fatal haemorrhage. The main functions of the powerful contractions ofthe womb, however, appears to be concerned in the ex-pulsion of the foetus, and then, as at other times, it isentirely independent of the will. Besides, the intensityof the contractions is not always related to the strength 42 Obstetrics—Dom esticated Animals.

When the contractions have been vigorous, thewomb rapidly diminishes; but if they have been slow andweak, the organ slowly contracts on itself. When thewomb does not contract quickly after delivery it is saidto be inert, and the cause is to be found in the expendi-ture of its contractile power, either through excessive dis-tention, a delivery too prompt or too slow, or generalweakness of the maternal system.
