NCBI ROFL: Finding the frequency of Fido's farts

By ncbi rofl | July 14, 2009 3:56 pm

Development of a technique for the in vivo assessment of flatulence in dogs.

“Rectal gases were collected via a perforated tube held close to each dog’s anus and attached to a monitoring pump fitted with a sensor that recorded hydrogen sulfide concentrations every 20 seconds. Patterns of flatulence were monitored for 14 hours after feeding on 4 days, and within- and between-dog variation was assessed over 4 hours on 4 consecutive days. Rate of hydrogen sulfide production (flatulence index) and frequency and number of emissions were evaluated as potential indicators of flatus characteristics. An odor judge assigned an odor rating to each flatulence episode, and the relationship between that rating and hydrogen sulfide concentration was determined.”
