ABSTRACT
The current study includes 34 purebred trotter mares and 292 gestations. Some of the mares are born in Bulgaria, and some are imported, as they represent four different trotter breeds – Standardbred, Orlov trotter, Russian and Italian trotter. The study refers to a period of 19 years, from 1997 to 2016. The aim of the recent study is to examine some reproductive traits of trotter mares – gestation length depending on foal gender and gestation length depending on the month of covering, and duration of covering estimated in days. We calculated duration of covering, length of gestation, gestation length in accordance with the foal gender (in days) and gestation length in accordance with the month of covering.
