Resumo: | An experiment was conducted with samples from six farms to study the interrelationship among mineral levels in soil, forage, and animal tissues during the wet and dry season of the year. Soil extractable copper was normal, 4.4 ppm, only on farm 1. Mean soil levels between 0.7 and 1.9 ppm were considered low on the other farms. Soil extractable copper means were 2.1 and 1.5 ppm during the dry and wet season, respectively. Forage copper values were deficient on farms 1,3,4 and 5; with a mean copper of 2.7 ppm on farm 3 there was a toxic level of Mo (9.2 ppm. Forage copper was 5.4 ppm during the wet season compared to 2.4 during the dry season. Liver copper levels were normal on all six farms, due to mineral supplementation. Soil extractable molybdenum was considered high on all six farms, and ranged from 16 to 24 ppm. Apart from farm 3, the other farms had nontoxic forage Mo value between 0.1 and 1.4 ppm. Normal liver molybdenum values were in evidence; a somewhat higher figure (3.8 ppm) found on farm 3 was, however, below the considered toxic level of 4 ppm. |

Apenas na fazenda 1, os níveis de Cu no solo mostraram-se normais, com valores médios em torno de 4,4 ppm. As demais fazendas apresentaram níveis considerados baixos, variando de 0,7 a 1,9 ppm. As médias de Cu, durante as estações seca e chuvosa, foram, respectivamente, 2,1 e 2,5 ppm. Foram encontrados níveis médios deficientes de Cu nas forrageiras das fazendas 1, 3, 4 e 5, sendo que a fazenda 3 apresentou 2,7 ppm de Cu em combinação com níveis tóxicos de Mo, 9,2 ppm. Nas estações chuvosa e seca, os níveis de Cu nas forrageiras foram 5,4 e 2,5 ppm, respectivamente. O nível de Cu no fígado dos animais foi normal em todas as seis fazendas, devido ao fornecimento de suplementos minerais. Os teores médios de Mo no solo foram considerados relativamente altos, variando de 16 a 24 ppm. A fazenda 3 apresentou níveis médios tóxicos de Mo nas forrageiras, 9,2 ppm. Nas demais fazendas, os níveis foram considerados normais, variando de 1,4 a 0,1 ppm. Os teores médios de Mo no fígado foram considerados normais. Apenas na fazenda 3, esses níveis foram relativamente altos. 3,8 ppm, mas abaixo do nível tóxico de 4,0 ppm.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSousa, J. C. deCorad, J.
