| description | The present study was conducted to evaluate the reproductive efficiency on heifers pregnancy rates from three different breeds, as embryo recipients. In the Cundiboyacense highlands, there has been few studies designed to determine which breeds beside, suitable for the environment, are the ones that can provide the best pregnancy rates, as embryo transfer recipients. The results were studied by descriptive statistical analysis using Excel and Minitab (Chi square x2 ) programs, with quantitative variables. The selection of recipients was based on the quality of the corpus luteum, CC normal reproductive tract, between 2 and 3 on a scale from 1 (very weak) to 5 (fat). The embryo transfer was performed by a non-surgically method: The pregnancy rates found were: for Normando Breed of 63%, Holstein, 55.5% and 44.4% for Brangus. The protocol used was Ovsynch, and the transferred embryos were frozen and thawed at the time of transfer. |

El presente estudio se realizó con el fin de evaluar la eficiencia reproductiva, medida en porcentaje de novillas preñadas, de tres razas bovinas, como receptoras de embriones. En el altiplano Cundiboyacense se han realizado pocos estudios tendientes a determinar cuáles razas, aptas para el medio, son las que pueden brindar mejores tasas de concepción, como receptoras, en transferencia de embriones. Los resultados se sometieron a un análisis estadístico descriptivo, utilizando los programas Excel y Minitab (Chi cuadrado x2), con variables de tipo cuantitativo. La selección de receptoras se hizo con base en la calidad de cuerpo lúteo, normalidad del tracto reproductivo, CC entre 2 y 3 en una escala de 1 (muy flaca) a 5 (cebada). La transferencia de embriones se realizó por el método no quirúrgico y se obtuvo un porcentaje de gestación en la raza Normando de 63%, en la Holstein, de 55.5%, y en la raza Brangus, de 44.4%. El protocolo utilizado fue Ovisynch, y los embriones transferidos fueron congelados y descongelados para el momento de transferirlos.
