2012 Annual Report
1)refine digestible and metabolizable energy (DE and ME, respectively) values for dried distillers grains with solubles (DDGS) ranging in crude fat content from 5 to 14%;.
2)validate DE and ME prediction equations determined for DDGS of varying fat content that were determined in past research;.
3)determine the net energy (NE) content in these same DDGS sources; and.
4)validate NE in a commercial setting.
Objectives 1 and 2: DE and ME Refinement and Equation Validation. As of June 15, 2012, 2 groups of 24 gilts have completed the metabolism portion of the trial with the final group scheduled to occur June 29 through July 27, 2012. Following this animal portion of the trial, laboratory analysis will be underway in earnest.
Objective 3: NE Determination and Equation Development. The NE trial is scheduled from July 9 through August 6, 2012.
Objective 4: NE Validation. The validation trial was scheduled to begin in September 2012, but in discussions with the commercial collaborator, we will start this experiment after all of Phase 1 has been completed and summarized, with an estimated date of March 2013.
