50th Anniversary of the California Net Energy System Symposium

The 50th Anniversary of the California Net Energy Systems Symposium will be held on the UC Davis campus, September 12-14, 2018.  This symposium builds on the pioneering work of Professors Lofgreen and Garrett who published their system in the Journal of Animal Science in 1968.  Their paper became the basis for how growing cattle are fed worldwide today, and was the most cited paper in animal science journals for over 25 years.  The symposium focus will thus be on cattle energetics, and how the system has been used since 1968 to improve our understanding of animal growth and nutrition through the presentation of fundamental and applied research by national and international speakers.  The program was designed to encompass key issues in animal nutrition ranging from energy utilization at the animal level to energy interactions at the cellular and subcellular levels.  Thirty-one internationally recognized speakers in a number of areas were identified and will give “state-of-the-science” presentations in each program session.  In this way, participants will have the opportunity to listen to some of the best scientists in their field and interact with other scientists to create rich partnerships for further interaction. 

Registration fees are $200 for the symposium, which includes a welcoming reception and introductory talks by Professor Richard Zinn, UC feedlot nutritionist working at the Imperial Valley Research and Extension Center, Holtville, CA, who will discuss “Glen Lofgreen, Bill Garrett, and the California Net Energy System.”  Once the delegates have been impressed by the challenges that Glen and Bill had in introducing a revolutionary new system (it took three years to get the paper accepted), Dr. Cal Ferrell, retired after a long career with USDA-ARS and a former Ph.D. student of Dr. Garrett’s will cover the “History of energetics leading to the net energy system.”  In the next two days, there will be seven additional sessions with three to five presentations in each:  The CNES in Practice, The CNES for Breeding Animals, The CNES for the Tropics, Modelling and the CNES, Nutrient Interactions, The CNES and Individual Efficiency, and The Future of the CNES. Lunch and Dinner will be provided Thursday Sept 13, and breaks both Th and Friday.
