摘要: Abstract The echogenicity of the early CL undergoes obvious changes during first 5 days luteal development. This phenomenon could potentially be used to estimate age in mares which have not been checked frequently for diagnosis ovulation. objective this retrospective study was determine accuracy estimating (Day 0 Day 4; 0 = Day ovulation) recipient examined time breeding season a commercial embryo transfer (ET) program. post-transfer pregnancy rate and loss 28 whose estimated at scan (at least 2 months gap from previous examination) were compared that 41 recipients ovulation had determined by daily examinations received an on respective day. There no difference (P > 0.1) (85.7 85.3%) or embryonic (12.5% 11.4%) between groups, respectively.
