Project Number: 6209-31630-002-17
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2005
End Date: Sep 30, 2008

Objective:
The objectives of this cooperative research project are to (1) evaluate the effects of the source (corn, sorghum grain or a blend) of distiller's grains on the digestibility of amino acids by swine; and (2) evaluate the relationship between the color of distiller's grains and amino acid digestibility in swine.

Approach:
In a digestion trial, swine will be fed diets containing dried distiller's grains made from corn (4 samples that vary in color), sorghum grain, or a blend of corn and sorghum grain. Small intestinal digestibility of amino acids will be determined in pigs with ileal cannula. Color of the distiller's grains will be compared using a Minolta colorimeter. The correlation between color measurements and in vivo amino acid digestibility will be determined.
