The general objective is to develop and adapt methods and protocols that make the preservation of germplasm (gametes and embryos) of different species of domestic animals of economic interest more efficient and safe. To do so, it has five action plans, ranging from the search for animal welfare indicators to estimate seminal quality to advanced transcriptome and proteome techniques to identify molecular changes that affect the response to cryopreservation. They are: PA1 (management), PA2 (animal

The embryo transfer technique (ET) began to be used in Brazil in the 70's, based initially on in vivo embryo production (by conventional superovulation). The potential of the technique as a tool in the multiplication of superior genotypes or in breeding programs resulted in its rapid assimilation by the productive sector, with a consequent increase of its use in the following decades. In recent years, the development of the in vitro embryo production technology has revolutionized the national ma

The project was conducted in order to identify and evaluate alternatives to produce genetically modified embryos and, subsequently, genetically modified ruminant animals, by identifying methods or procedures that enable the production of ruminant transgenic embryos in a more efficient way, reducing time and costs. Such procedures, associated with the insertion of genes of interest, may allow the generation of genetically modified animals capable of producing recombinant proteins important for an

Brazil has several breeds of domestic animals that have been developed from breeds brought by Portuguese colonists at the time of discovery. Over the centuries, these breeds have been subjected to natural selection in environments in which they live to the point of presenting specific characteristics to adapt to these conditions. They are known as “creole", "local" or "naturalized".

Currently, many of these breeds are endangered of extinction because over the centuries, they have

The Innovation Network in Animal Reproduction adds skills among the different teams that work in the area of ​​animal breeding biotechnology at Embrapa with the aim of increasing the competitiveness of animal production chains in Brazil. Among the objectives, the following stand out: creation of new technological platforms in this area, transfer of technologies generated by the component projects and consolidation of Embrapa as a reference institution for the formation of public policies related

Reproductive biotechnologies, particularly in vitro embryo production, can be useful to improve the milk productivity in Brazil by accelerating the genetic gain and reducing the intervals between generations. Genomic selection associated with reproductive biotechnology may be applied at the embryonic stage to promote the selection of embryos with desirable genetic traits and disposal of those with undesirable traits; consequently, maintenance costs of recipient cows would be reduced and efforts
