Researchers appeared on the carbon dioxide they exhaled on the treadmill and located traces of amino acids, the constructing blocks of protein.
The ratio of CO2 to oxygen (respiratory trade ratio) stayed the identical in any respect speeds.
It suggests the bats’ principal supply of vitality was their protein-rich blood meal, moderately than the saved carbohydrate and fats primarily utilized by most different mammals.
Researchers say it reveals “how strongly metabolism can be shaped by a specialized diet” because the weight loss program of vampire bats is comparatively low in carbohydrate and fats.
Frequent vampire bats are solely about 7-9cm lengthy however can double their weight after one blood-sucking feeding session.
They emerge at evening, utilizing sonar to navigate and detecting prey utilizing warmth sensors of their face. A powerful anticoagulant of their saliva stops the blood of their prey from clotting throughout a meal.
The research, by Giulia Rossi at McMaster College and Kenneth Welch from College of Toronto, is revealed within the journal Biology Letters.
