Use of a liquid diet as the sole source of nutrition in six dysphagic horses and as a dietary supplement in seven hypophagic horses.

Six horses with dysphagia (attributable to botulism, glossitis, or guttural pouch mycosis) were given a commercially available liquid diet as the sole source of nutrition. Seven horses with hypophagia caused by severe bacterial pleuropneumonia or peritonitis were given the liquid diet to supplement food consumed voluntarily. The liquid diet was administered through a nasogastric tube 2 or 3 times daily. Body weight did not change significantly, and pertinent laboratory values remained at satisfactory concentrations throughout the feeding period. Serious complications were not encountered. Three horses developed loose, low-volume feces, but did not require treatment.
