| Abstract: | To shorten the breeding period and improve performance in cattle production,embryo transplantation techniques were applied.735 head cows were transplanted among 1334 heads of receptor and 352 became pregnant.Pregnant percentage was 47.86% and Alive calves were 296.it was showed showed that the reproduction performance,uterus condition,nutrition and oestrus detection of receptor were very important for embryo transplantation. |
