Key messages

  • One replicated, before-and-after study in the USA found that supplementing an animal-protein diet with taurine, increased plasma taurine levels in maned wolves.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated, before-and-after study in 2001 of maned wolves Chrysocyon brachyurus in a research centre in the USA, found that supplementing a protein-based diet with taurine increased the average plasma taurine levels. When fed a supplemented animal-based protein diet, average plasma taurine was higher (91.18 nmol/ml), and within target domestic canine reference ranges, compared to no supplement (animal-based protein: 18.79 nmol/ml; plant-based mean: 4.03 nmol/ml). Four wolves were maintained on the commercial diet (animal-based protein) and two were maintained on an experimental diet (plant-based protein). Four weeks prior and at the end of the trial, animals were restrained and sedated to collect a 12 ml blood sample. Due to clinical signs including weight loss and decreased appetite, the diet trial was terminated early and taurine supplementation (0.3% concentration) was deemed necessary. Taurine concentrations were monitored over a four-month period.
