Resumen
Descripción
The Zebu dairy breeds represent a valuable and strategic genetic resource for Brazilian circumstances. The development of breeding programs involving the dairy Zebu, although recent and still in need of some implementations and adjustments, is quite relevant given that there is no semen of tested bulls from other countries available in the international market. This article summarizes the evolution of the Dairy Gir and Dairy Guzerá Breeding Programs in Brazil.
