Images illustrating a native grassland in southern Brazil, source of tannin and the primary forage resource for sheep and cattle in this region. In image A, the high floristic diversity characteristic of these grasslands is evident. Image B provides a detailed view of one of the main legumes found in these systems (Desmodium incanum, indicated by arrow), which, according to studies conducted by our laboratory, can contain more than 6% condensed tannins per kilogram of dry matter. The final image (C) shows a sheep grazing in a native pasture, equipped with a fecal collection bag used to estimate intake. Source: Authors.
