Background: Digestive disturbances in ruminants are associated with forage shortages during periods of dry weather. Foodsavailable at this time are generally of poor quality and low digestibility, which makes it necessary to pursue alternativefood sources where available. Grain-heavy diets; concentrated rations rich in rapidly fermenting carbohydrates; and whey,tubers and fruits high in starch and glucose, contribute to ruminal acidosis. Here we report a case of ruminal acidosis dueto excessive ingestion of the mango fruit (Mangifera indica), “manguita” cultivate, by an adult bovine.Case: In the municipality of Boa Vista, Roraima, during December, a Dutch female bovine adult, weighing approximately600 kg, was observed showing signs of apathy for two days with diarrhea. The animal had a rumenostomy with flexiblecannula in the left paralumbar fossa and was in the final third of gestation. During clinical examination, the animal was inseason, and an increase in the volume of the left dorsal region and changes in physiological variables were observed (lightlypale mucosa, capillary filling time of 4 s, heart rate [HR] of 82 beats per min; respiratory rate (f) of 30 moments per min;absence of ruminal movements and rectal temperature [RT] of 39.5°C). Upon removal of the cannula lid, a considerableamount of liquid and a large quantity of mango (Mangifera indica), “manguita” cultivate, were observed. Blood sampleand ruminal fluid were collected and ruminal contents weighing approximately 40 kg were evacuated. Physical-chemicalanalysis of the ruminal liquid (pH = 4.0, brown color, aqueous consistency and characteristic fruit odor) resulted in adiagnosis of ruminal acidosis. Treatment included administration of fluid therapy (Lactate Ringer; 2 mL/kg/h), hepatoprotector (1 mL/20 kg), antimicrobial (Ampicillin Sodium; 10 mg/kg/IV and Sulfadoxine; 30 mg/kg/IV) and non-steroidalanti-inflammatory (Meloxicam; 0.5 mg/kg/IV) drugs, associated with evacuation...
