With 200 million head, Brazil is the largest world producer of cattle. However, national beef cattle farming is characterized by low productivity and a large variation in beef quality. This second aspect can be justified by the large Zebu fraction found in the genetic base of our herds. Zebu breeds normally present less soft beef with lower marbling when compared with taurine breeds, making the appraisal of this meat difficult in international markets. Therefore, the development of genotypes that are adapted for meat tenderness of high added value in the global market is of utmost importance for the Brazilian cattle sector. The BRGN Polled Nelore herd by Embrapa Cerrado, which was initiated in 2000, uses genetic material from the OB herd, a trademark which has worked in the selection of the Polled Nelore breed for 60 years. In this context, this project goals are to identify, genetically characterize, multiply, and select animals with greater potential for meat tenderness. The animals approved in the several assessments will compose a sample of animals bred for meat tenderness to be later incorporated into the herd of Embrapa's BRGN trademark of Polled Nelore cattle.
