Comparison of four digestibility markers to estimate fecal output of dogs

An abstract of a study by Alvarenga et al determining the effect of using alternative markers to estimate fecal output of dogs and calculate diet digestibility is presented. The study suggests that TiO2 may be a better marker to estimate fecal output in dogs than Cr2O3. TiO2 is considered GRAS and i...

Description
Summary:An abstract of a study by Alvarenga et al determining the effect of using alternative markers to estimate fecal output of dogs and calculate diet digestibility is presented. The study suggests that TiO2 may be a better marker to estimate fecal output in dogs than Cr2O3. TiO2 is considered GRAS and is a common colorant in pet foods. The use of the AIA technique needs to be further studied since it represents a potential option for evaluating diets that are difficult to incorporate external markers.
