title: [Evaluation of a number of commercial diets for iguana (Iguana iguana), bearded dragons (Pogona vitticeps), and land and marsh tortoises].
abstract: Fifteen commercially available, complete diets for iguanas, bearded dragons, and chelonians were analysed and compared with the ideal composition of a diet formulated by the authors. The clinical risks of feeding with a too high or a too low content of specific nutrients are described. Nutrient deficiencies are not expected if these diets are the sole source of nutrients. However, one diet had only a marginally adequate protein content, five diets for herbivorous reptiles contained a too low percentage of crude fibre, three diets contained an undesirably high percentage of calcium, and three diets had an extremely high iron content. As a rule, the calcium and iron contents of diets are not declared on the food label, which complicates evaluation of the diets.
