| Resumen en inglés | Further results are given of studies on mineral deficiencies in cattle and sheep carried out by the authors over the last 25 years, and which began in the early fifties. The studies consisted in obtaining case histories of diseases possibly caused by mineral deficiencies, in field observations and clinical examinations of cattle and sheep affected by these diseases, in the performance of postmortem examinations with collection of material for histopathological examinations and chemical analyses of liver samples for copper, cobalt, zinc, mangnese, selenium and iron. In order to include also subclinical mineral deficiencies, which do not cause characteristic manifestations, liver samples of animals that succumbed to other diseases, mainly plant poisoning, were collected for chemical analyses. For interpretation the anlytical data were evaluated always together with the case history and the clinic-pathological picture of the animals. Copper deficiency was diagnosed in the counties of Barra do Bugres (Mato Grosso), Parintins (Amazonas) and Carolina (Maranhão), in northeastern Minas Gerais, in the southern part of the State of Rio de Janeiro and in the counties of Itaqui and Uruguaiana (Rio Grande do Sul). Low copper values were also found in cattle affected by "ronca" [snoaring disease], of yet not established etiology, in the county of Aquidauana (Mato Grosso do Sul). Cobalt deficiency was diagnosed in the counties of Barra do Bugres and Diamantina (Mato Grosso), Boa Vista (Roraima), Manaus and Itacoatiara (Amazonas), in nor |
