Hourly distribution of time of parturition in the domestic goat.

Data on 2589 records collected during 12 years in one breed of dairy goats that were maintained in stables were analysed to examine the influence of various factors on the time of parturition. Parturitions were observed from mid-January to the end of April. Hourly frequencies of birth showed an unimodal distribution with maximum births at midday and minimum births around midnight with 90.
