Tridge summary

A recent study conducted at the Donoso Agrarian Experimental Station of the National Institute of Agrarian Innovation (INIA) has found that the Brahman, Braunvieh, Gyr, and Simmental cattle breeds have a high genetic diversity. The research used molecular techniques to identify that the Braunvieh breed has the highest heterozygosity, while the Brahman breed has the lowest. All breeds had negative inbreeding coefficient values, indicating no consanguinity and a large number of heterozygotes. The findings will be used to develop technologies for animal genetic improvement and to manage genetic resources effectively to prevent the loss of genetic variability in these breeds.

A recent study has shown that the cattle of the Brahman, Braunvieh, Gyr and Simmental breeds from the National Institute of Agrarian Innovation (INIA), of the Ministry of Agrarian Development and Irrigation (Midagri) have a favorable genetic diversity of high value, which will allow develop technologies for animal genetic improvement, publishes Inforegion. The study has used molecular techniques of genotyping by panels of markers carried out by INIA, as part of the work of the Precision Agriculture-Agpres and PromegNacional projects, which seeks to strengthen the effective management of cattle genetic resources. According to the research, the Braunvieh breed has the highest observed heterozygosity (0.43±0.01), while the Brahman breed has the lowest (0.37±0.02). In addition, it was identified that the inbreeding coefficient (FIS) values had negative values for all breeds, evidencing that there is no consanguinity, but a large number of heterozygotes. These results are extremely ...
