Research Project: Validation of Digestible and Metabolizable Energy Prediction Equations, and Determination of Net Energy of Corn Ddgs Sources Varying... Project Number: 3625-31000-004-33
Project Type: Reimbursable

Start Date: Nov 15, 2011
End Date: Aug 31, 2014

Objective:
Determine digestible energy (DE) and metabolizable energy (ME) in three samples of oil extracted dried distillers grains with solubles (OE-DDGS), validate prediction equations previously determined for OE-DDGS fed to growing pigs, and determine net energy (NE) of these same OE-DDGS sources.

Approach:
1. Obtain three samples of OE-DDGS and analyze for crude protein, ether extract, starch, fiber, ash, and minerals. 2. Conduct DE and ME digestibility study with pigs fed the three OE-DDGS sources and compare the determined DE and ME values to predicted values using a prediction equation generated from a previous experiment. 3. Feed the three samples of OE-DDGS to growing pigs for 28 days and determine NE of each OE-DDGS source utilizing the whole body composition technique.
