The aim of this study was to evaluate results of induction of the parturition with small doses of oxytocine in 9 mares. All inductions were carried out in mares after 335 days of gestation with clinically confirmed physical readiness for delivery. Initial dose of oxytocine for parturition induction was estimated as 10 to 15 iu. as an i.v. bolus. Total dose of oxytocine, the time from the initial dose of this hormone to onset of the consecutive stages of the labour and the vitality of the offspring were analysed. In 7 mares, initial dose of oxytocine from 10 i.u.to 15 i.u. was sufficient to develop properly all stages of the parturition. In this cases, the time from initial dose of oxytocine to the end of II stage of labour was varying from 25 to 40 min. In 2 other cases, according to insufficient labour pains, second dose of oxytocine was used, consequently 6 i.u. in the first and 20 i.u. in the second mare. In this cases manual help during II and III stages of labour was performed. All newborns during post partem examination had a high vitality score. Summing up, in mares in which the induction of parturition was carried out close to the term of the natural labour, the initial dose 10-15 i.u. of the oxytocine as an i.v. injection, is sufficient to initiate parturition with the course similar to the natural one and remaining chances to farther control its consecutive stages.
