Proceedings... Brasília, DF: Embrapac2016  ap.268-271.  a(Embrapa Gado de Corte. Documentos, 216).  aIn Brazil, despite the lack of accurate statistics on the contribution of each type of system in total milk production, it is known that pastures represent the main feed source in most production systems (IBGE, 2010). However, a major concern with respect to this factor is related to the potential environmental impact the degradation of thousands of hectares of these pastures may have.  aHolstein  aGado Jersey  aGado Leiteiro  aVaca holandesa1 aRODRIGUES, P.
