title: [Hematological studies on cows pasturing on Brachiaria radicans napper in winter time (author's transl)].
abstract: A group of six adult cows Holstein-Frision was left grazing on a pasture formed exclusively with Brachiaria radicans Napper. This investigation was was undertaken during the rather dry winter with the graminea showing a low nitrat content. The animals failed to present any of the typical simptoms of intoxication and the weekly clinical and hematologycal examinations detected a hyperchromic macrocytic anaemia eventually jointed to anisocytosis and basophylic stippling in the red cells. The anaemia was controlled by removing the animals from the pasture.
