description During the years 2012-2017 Multiovulation and Embryo Transfer (MOET) technique was applied in Holstein and Girolando F1 animals at the Animal Reproduction Unit (URA), of the Escuela de Zootecnia of the University of Costa Rica, with the aim to create and evaluate a Girolando herd in the Costa Rican Atlantic. Female embryo donors were selected at external farms and URA. Selection in external farms was done through the information of breed herd books and farm records, while in URA, through the data of lactation and performance of the offspring. In addition, an estimation of partial costs of embryo production was obtained. URA evaluated animals, as part of the embryo donors selection, showed an average daily milk production of 11.1 kg, with an average lactation length of 296 days, on a single daily milking and with a calf at the cow side. The weaning was carried out at 7 months of age, with an average weight of 255 kg (244 kg for females and 262 kg for males). Overall, in both URA and external farms, 38 collections were done in 24 selected donors, from which 381 structures were collected, 73.5% fertilized and 26.5% unfertilized. From those fertilized structures (embryos), 47.3% were considered transferable (quality 1 and 2 according to the International Society of Embryo Transfer, IETS), for an overall average of 4.8 transferable embryos per collection. 83 fresh embryo transfers and 34 frozen embryo transfers were performed, from which 33.7% (28/83) and 5.9% (2/34) pregnancy rates were obtained, respectively. The low pregnancy rates obtained, compared to literature reports, are not normal results, but are related to this particular study. The production cost of an embryo,  due to consumables, hormones and semen was US$62.5 dollars. Production and embryo transfer technique collaborated in the creation and development of the Girolando herd of the Animal Reproduction Unit of the University of Costa Rica.

Las hembras donantes de embriones se seleccionaron tanto en fincas externas como en la URA. La selección en fincas externas se realizó a través de la información de los registros de raza y de finca, mientras que en URA, a través de los datos de lactancia y desarrollo de las crías. Además, se realizó una estimación parcial de costos para la producción de embriones. En los animales evaluados en URA, como parte del análisis para la selección de donantes de embriones, el promedio de producción diaria de leche fue de 11,1 kg, con una duración de la lactancia promedio de 296 días, a 1 ordeño diario y con ternero al pie. El destete de las crías se realizó a los 7 meses de edad, con un peso promedio de las crías de 255 kg (promedio de 244 kg en hembras y 262 kg en machos). En total, tanto en URA como en fincas externas, se realizaron 38 colectas en 24 donadoras seleccionadas, de las cuales se colectaron 381 estructuras, un 73,5 % fertilizadas y un 26,5 % infertilizadas. De aquellas estructuras fertilizadas (embriones), un 47,3% fueron consideradas transferibles (calidad 1 y 2 de acuerdo a la Sociedad Internacional de Transferencia de Embriones, IETS), para un promedio general de 4,8 embriones transferibles por colecta. Se realizaron 83 transferencias de embrión en fresco y 34 transferencias de embriones congelados, de los cuales se obtuvo tasas de preñez de 33,7% (28/83) y 5,9% (2/34), respectivamente. Las bajas tasas de preñez obtenidas, comparadas con lo visto en literatura, no son resultados normales, pero son las relacionadas con este estudio en particular. El costo para producir un embrión, por concepto de productos consumibles, hormonales y semen fue de US$62,5 dólares. La producción y transferencia de embriones colaboró en la creación y desarrollo del hato Girolando de la Unidad de Reproducción Animal de la Universidad de Costa Rica.Universidad de Costa Rica2020-12-09info:eu-repo/semantics/publishedVersionArticleArtículoartículo originalhttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlaudio/x-m4ahttps://revistas.ucr.ac.cr/index.php/nutrianimal/article/view/4507710.15517/nat.v14i2.45077Nutrición Animal Tropical Journal; Vol. 14 No. 2 (2020): Nutrición Animal Tropical: July-December; 187-208Nutrición Animal Tropical; Vol. 14 Núm. 2 (2020): Nutrición Animal Tropical: Julio-diciembre; 187-2082215-352710.15517/nat.v14i2reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/nutrianimal/article/view/45077/44851https://revistas.ucr.ac.cr/index.php/nutrianimal/article/view/45077/44852https://revistas.ucr.ac.cr/index.php/nutrianimal/article/view/45077/44859acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-12-07T16:20:30Zoai:portal.ucr.ac.cr:article/45077Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:58:32.081Portal de Revistas UCR - Universidad de Costa Ricafalse
