Course on indirect calorimetry

Directly following the 4th International Symposium on Energy and Protein Metabolism and Nutrition in Sacramento, CA (USA) from September 9-12, 2013, Wageningen University, the Netherlands (WU), and the University of California, Davis, CA, USA (UC Davis) will jointly organize a course on indirect calorimetry and selected applications. The course will be held on September 13-15, 2013 in Davis, CA.

For whom?

The course is aimed at educating those (PhD students, technical staff, researchers) who are, or aim to use measurements of gaseous exchange (CO2, O2, CH4, etc) in their research program, and/or are setting up facilities in which those measures can be performed, either with or without climate control.

Venue

Department of Animal Science, Meyer Hall, One Shields Ave., UC Davis, Davis, CA, USA.

Lodging

Although the main ISEP conference is in  Sheraton Grand Hotel (Sacramento, California), but the Satellite Symposium will be held in Davis, California.  The hotel reservation for Satellite Symposium in Davis is on your own.  Please use Hyatt Place (you can do it on the web—use Corporate/Group # booking code G-ANSC  or by phone 1-888-492-8847) by August 16, 2013.  The web site for Hyatt Place is: http://ucdavis.place.hyatt.com/en/hotel/our-hotel.html

Registration and fee

Registration for the course can be selected as an option when registering for the ISEP conference at http://isep.ucdavis.edu/registration.html The Registration Fee will be $300 for PhD students and $600 for other participants. It includes breaks on Friday-Sunday and lunch on Saturday and Sunday. Lodging arrangements in Davis are your responsibility, but we will email you in early June of reduced rates for local hotel(s). The maximum number of participants is 30, and will be dealt with on a first-come first serve basis. If the number of registrations does not exceed 10, the course will be cancelled. In that case, registrants will be notified before June 1st.

Preliminary Program

Friday September 13 

13:00 – 13:30:  Walter Gerrits, WUR, NL.
 Welcome, intro to course, intro to indirect calorimetry:
Brief history, course overview.

13:30 – 14:15: John Lighton, Sable Systems Intnl, USA.
Design of calorimeters
: General principles, brief overview - emphasis on lab scale systems.  

14:15 – 15:00: Marcel Heetkamp, WUR, NL Ermias Kebreab, UC Davis.
 Design of calorimeters for large animals: Dealing with large, climatized systems with flexible walls (MH), and with mobile systems to use in field measurements (EK). 

15:00 – 17:00:  John Lighton, Sable Systems intnl, USA Ermias Kebreab, UC Davis, USA
Tour to facilities; demo calorimetry setup: Visit calorimetry facilities atUC Davis, demo-setup of a calorimetry system.

20:00 – 21:00: Walter Gerrits, WUR, NL
Informal session: Participants will present their ideas on (future) use of calorimetry system.

Saturday September 14

08:30 – 09:30: Walter Gerrits, WUR, NL Etienne Labussière, INRA, FR
Calculating heat production from gas exchange: Usually done by the Brouwer equation. Explanation of the basics and assumptions. Comparison with serial slaughter trials. Also modelling of O2 consumption and CO2 production. Potential hick-ups in particular species.

09:30 – 11:00: Sven Alferink, WUR, NL Marcel Heetkamp, WUR, NL
Calculating heat production and energy balance
: Computer practical with the objective of dealing with the steps from measuring gas concentrations, air flow, etc into a complete energy balance; dealing with two datasets: one generated on Friday afternoon and an example dataset  

11:30 – 13:00: Etienne Labussière, INRA, FR   
Modeling of heat production: Computer practical separating heat production into components like diet induced thermogenesis (short term vs long term), activity related heat production, fasting heat production 

14:00 – 15:00:  Ermias Kebreab, UC Davis, USA 
Application 1: methane Measurement of methane emissions in different systems, greenfeed systems vs hood chambers vs open circuit systems. 

15:00 – 16:00: Cesar Pinares, AGResearch, NZ
Application 2: use of tracer gases Measurement of methane emissions using tracer gases like SF6 or others. Methodological issues.  

16:00 – 17:00: John Gaughan, UQ, AU Marcel Heetkamp, WUR, NL
Application 3: heat and cold stress Measurement of heat production and energy balance under different climatic conditions (temperature, relative humidity).   

Sunday September 15

8:30 – 9:30:  Application 4: quantifying activity  Different methods of quantifying physical activity (beam interruption, radar, and more sophisticated) and ways to calculated activity heat 

9:30 – 10:30: Joost van den Borne, WUR, NL 
Application 5: stable isotope tracer methodology Moving from a complete energy balance towards substrate oxidation: use of stable isotopes 

11:00 – 12:00: Henry van den Brand, WUR, NL
Application 6: metabolism during incubation of eggs and post-hatching (tentative) Measurement of CO2 production and O2 consumption of eggs during incubation, its relationship with incubation conditions and the impact on early life energy expenditure
