Conteúdo: 	Previous reports showed that beef cattle grazing Paspalum dilitatum, Brachiaria multica and Sporobolus virginicus pastures in south eastern (1), northern coastal (2) and central Queensland (3) had low blood and liver Cu levels unassociated with clinical signs. Supplementation with Cu did not effect weight gains in a number of experiments (1) whereas significant responses were obtained in weaner but not in adult cattle (2,3). Analyses indicated that the low Cu status was not due to either a low Cu content of the grasses or to Mo and S interaction. However, the grasses grazed contained from 10-23% crude protein and it has been shown (4) that the capacity of the rumen flora to form sulphide is increased by a relative protein excess in diets of high digestibility. Under these conditions the possibility of formation of poorly utilized CuS will be increased.
