Abstract
We expose a stable of 11 horses that showed acute symptomatology compatible intoxication. The horses consumed concentrated feed and hay, but for seasonal reasons, were fed with grass of Digitaria swazilandensis . The horses were fasted for 48 hours with water ad libitum . Symptomatic treatment was instated and all horses improved. The grass is introduced again and there is relapse and death of 3 horses, that are necropsied, where it confirms the suspicion of intoxication with digestive, hepatic and encephalic affectation. Samples of the concentrate feed, forage and water are collected for toxicological bacteriological and fungal analysis and high concentrations of nitrates in the pasture are evidenced. Nitrate intoxication is uncommon in horses and for a correct diagnosis it is necessary to perform a pathological study and determination of nitrate levels of possible sources of contamination.

Summary
Se expone el cuadro de intoxicación sufrido en una cuadra de 11 caballos de diferentes edades, razas y sexo que fueron remitidos al Complejo Hospitalario Veterinario de Corozal-. El primer caso tuvo aparición súbita 4 días antes, pero muere a las pocas horas. Primero se realizó la exploración en 8 caballos en los que se observa deshidratación leve, taquicardia, taquipnea, sudoración, decoloración de la mucosa gingival, temblores, ataxia grave, temperatura corporal alta (39.5-40 oC), dolor abdominal con poca respuesta a la analgesia. Tres de los caballos de la cuadra no mostraban aun sintomatología (Figura 1). Figura 1: caballo afectado, con ataxia evidente y base de sustentación amplia de las extremidades.
