Descripción
The aims of this study were to evaluate the efficacy of a hormone protocol for fixed time embryo transfer, and to investigate factors usually associated with the achievement of high pregnancy rates in bovine recipients. Crossbred non-lactating cows, and heifers (n=259) were treated with the following protocol: 2mg of estradiol benzoate (EB) plus an intravaginal progesterone device (CIDR; day 0); 400 IU of eCG (day 5); PGF2α and CIDR withdrawal (day 8); and 1mg of EB (day 9).
