Combining a metabolic cage (with urine and feces collection) and respirometry: It's easy!

Measuring metabolic rates in a stress free home cage environment is great for the experimental animal, but can't be implemented if quantitative urine and feces collection is also required. Metabolic cages exist that are specially designed for accurate collection of urine and feces, and as this blog post shows, can easily be adapted for metabolic measurement using a Promethion pull-mode metabolic phenotyping system.

Activity Metabolism Measurements Made Easy in Metabolic Phenotyping

Correlating activity and energy expenditure in "legacy" metabolic phenotyping systems is almost impossible. However, the new Promethion-C parallel, continuous metabolic phenotyping system makes it easy. We demonstrate this by extracting data on the metabolic cost of a specific activity from a Promethion-C continuous, parallel metabolic phenotyping system - data that normally requires a treadmill, a skilled human operator, extensive training, and a lot of stress for all concerned. And we conclusively prove that we can do it accurately, on multiple animals simultaneously, and without stress.
