Objectives of this study were to evaluate factors that could affect pregnancy rate after embryo transfer (ET) in lactating dairy cow recipients. The trial was conducted at a dairy farm located in Descalvado, SP, Brazil from October 2003 to September 2004. From 1037 cows with CL that were treated with an injection of PGF2a, 43.3 % were detected in heat; 263 were previously assigned at day of PGF2a injection for AI and 186 for ET. Ovulation rate was 85.7 % (385/449). Pregnancy rate for cows with CL for AI and embryo transfer recipients were 36.5 % (84/230) and 58.7 % (91/155) at day 25 and 33.0 % (76/230) and 45.8 % (71/155) at day 46, respectively. Embryonic loss were 9.5 % (8/84) for the AI group and 21.9 % (20/91) for the ET group. Average...
