The aim of the research was to evaluate Latvian native cow breeds' (Latvian Brown and Latvian Blue) and Danish Red cow embryos (E) obtained in frame of ERAF project No: 1.1.1.1/16/A/025 BioReproLV (2017-2020). An embryos were obtained from 21 donorcow (2 - 15 years old). An E harvest was 146 E (0-18 E/cow, average 8.33±5.90 E/cow and 5.54±4.96 E/cow were transferable). ET was done in 79 recipients. Pregnancy was approved in 22 (27.85%) ET cases. Using fresh E (n=52) were obtained 18 (34.6%) pregnancies, but using thawed E (n=21) were obtained just 3 pregnancies in 16 recipients group which had appropriate time to detect pregnancy (16 recipients) and so were received 18.8% pregnancies. In conclusion, it is better to transfer fresh embryos. In our study excellent or good quality embryos in stage of development "compact morula" resulted with better pregnancy rate than blastocysts.
