Assessment of pregnancy rate when transfering bovine embryos using two synchronization methods

The objective of this review is to evaluate the pregnancy rate in crossbred cows in the transfer of bovine embryos through the use of two methods of synchronization of heat at fixed time with equine chorionic gonadotropin hormone and with physiological serum (control group). The transfer of embryos...

Pregnancy rate Embryo transfer Heat synchronization Tasa de preñez Transferencia de embriones Sincronización de celos The objective of this review is to evaluate the pregnancy rate in crossbred cows in the transfer of bovine embryos through the use of two methods of synchronization of heat at fixed time with equine chorionic gonadotropin hormone and with physiological serum (control group). The transfer of embryos is a technique for the genetic improvement of cattle that is currently being widely disseminated in our country; Thanks to the existence of genetic improvement programs and the spread of artificial insemination, however, it presents difficulties in heat detection and, above all, low conception rates. For the collection of information, it was necessary to implement the methodological research better known as Methodology Research where the search criteria were: “Pregnancy rate” + embryo transfer + crossbred cows; Embryo transfer + IATF synchronization methods + crossbred cows, the inclusion criteria being: Pregnancy rate + embryo transfer + cross-breed cows, Embryo transfer + IATF synchronization methods in cows, Publication since 2016, finally the exclusion criteria were: Age: below 30 months and above 60 months, Irregular estrous cycles (Abnormal), Cows without identification or reproductive record, Postpartum problems (metritis, endometritis, vaginitis and pyometra), for which it was considered as motor from searches to: academic Google. Since the mid-1970s, embryo transfer technology has been used commercially to rapidly multiply animals of valuable genetics. Subsequently, with the freezing of embryos, the possibility of moving animals between countries with sanitary barriers is created. El objetivo de la presente revisión es evaluar la tasa de preñez en vacas mestizas en la transferencia de embriones bovinos a través de la utilización de dos métodos de sincronización de celo a tiempo fijo con hormona gonadotrofina coriónica equina y con suero fisiológico (grupo control).La transferencia de embriones es una técnica para el mejoramiento genético del ganado que actualmente está siendo muy difundida a nuestro país; gracias a la existencia de programas de mejora genética y a la difusión de la inseminación artificial, sin embargo, presenta dificultades en detección de celo y sobre todo bajos índices de concepción. Para la recopilación de información fuenecesaria la implementación de la investigación metodológica más conocida como MetodologyResearch donde los criterios de búsqueda fueron: “Tasa de preñez” + transferencia de embriones + vacas mestizas; Transferencia de embriones + métodos de sincronización IATF + vacas mestizas, siendo así los criterios de inclusión: Tasa de preñez + transferencia de embriones + vacas mestizas, Transferencia de embriones + Métodos de sincronización IATF en vacas, Publicación desde 2016, finalmente los criterios de exclusión fueron: Edad: por debajo de 30 meses y por encima de 60 meses, Ciclos estrales irregulares (Anormal), Vacas sin identificación ni registro reproductivo, Problemas del puerperio (metritis, endometritis vaginitis y piometra), para lo cual se consideró como los motores de búsquedas a: Google académico.
