After intensive import during last few years in Bulgaria, and last year and a half in Scotland, lots of data has been gathered according to reproduction performance in both countries. The aim of this study was to establish the reproduction performance of imported heifers. The study was carried out in three industrial farms - two of which in Bulgaria, and one – in Scotland. After calving each animal was monitored daily and all the symptoms were registered in computer software. Results showed significant increase in puerperium length – 39.37±10.19 (Р≤0.01). Conclusions we made were: reproductive performance in imported dairy heifers is in average for examined farms
