GLOMICAVE researchers have presented the study entitled “Heifers carrying male and female fetuses differ in their metabolome before ET” during the 16th International Congress of the Spanish Association for Animal Reproduction (AERA), celebrated from 20th – 22nd of October in Gijón (Spain).
Enrique Gómez, head of the research department of SERIDA, and Isabel Gimeno, pre-doctoral researcher at SERIDA, have participated in the Congress and presented the poster, which has been produced under the framework of the GLOMICAVE project. The results of the study were also presented as an oral communication given by Isabel Gimeno.
In cattle, the recipient blood metabolome predicts pregnancy, and the endometrium reacts to embryonic sex. However, it is unknown whether embryos of each sex need an adapted pregnancy-competent recipient to develop, which could lead to metabolic differences between recipients carrying male (M) or female (F) fetuses.
The work presented showcases the results obtained with different studies carried out within the project which suggest that maternal metabolism prior to embryo transfer can favor the implantation and the development of either male or female embryos.
The poster has been produced by Isabel Gimeno and Enrique Gómez, in collaboration with Susana Carrocera from SERIDA; Pascal Salvetti and Julie Gatien from project’s partner ALLICE, and J.J. Pérez-Jánez from Gijón Farmers and Users Cooperative.
AERA is the Spanish Association for Animal Reproduction a national meeting point for all the professionals, researchers, technicians and other stakeholders involved and dedicated to the animal reproduction sector.
