Propylene glycol toxicosis in a llama

Abstract

A 4-year-old female llama was examined because of a 6-week history of weight loss, anorexia, and lethargy. Acetonemia and hepatic lipidosis were diagnosed on the basis of high serum β-hydroxybutyrate concentration and hepatic enzyme activities. Propylene glycol toxicosis was diagnosed on the basis of history and analysis of fluid from the first stomach compartment and was presumed to be a result of excessive oral administration of propylene glycol gel by the owner. The llama was treated with antibiotics and by means of transfaunation of rumen fluid daily for 5 days, after which it began eating again. Two weeks later, the serum β-hydroxybutyrate concentration was within reference limits, and the llama was eating well and gaining weight. Eight months later, the llama was healthy and had gained back the weight lost during the illness.
