The purpose of this study was to evaluate foaling rates of mares that were rebred after the pregnancy loss in same reproductive season and to examine factors influencing them in Hidaka, Japan. The study included 82 Thoroughbred mares that had experienced pregnancy loss. The foaling rate of the mares that were rebred after pregnancy loss was 57.3%. The foaling rate decreased as the period until detection of pregnancy loss increased. Aging and lower body condition score of mares decreased the foaling rate.
本研究的目的是评估在日本日高地区同一繁殖季节妊娠丢失后再次配种的母马的产驹率，并研究影响产驹率的因素。该研究纳入了82匹经历过妊娠丢失的纯种母马。妊娠丢失后再次配种的母马的产驹率为57.3%。随着妊娠丢失检测时间间隔的增加，产驹率下降。母马的年龄增长和身体状况评分降低会使产驹率下降。
