==Stages of Parturition==
*Stage 1: this is the preparatory stage, starting at the onset of regular uterine contractions followed by cervical dilatation and the foetus assuming the correct disposition for passage through the birth canal.
*Stage 2: the expulsive stage, characterised by the onset of abdominal contractions which together with uterine contractions lead to foetal expulsion
*Stage 3: separation and expulsion of the foetal membranes. In polycotous species second and third stages are often inter-mixed.
The following table summarises the normal time taken to progress through the stages of parturition in different species.
