In 12 experiments with S.C.W.L. roosters it was shown that for each of 12 feedingstuffs there was a linear relationship between feed input and the amount of energy voided as excreta.

When dextrose was fed the energy voided as excreta did not increase with dextrose input; conse...

Soluble corn fiber...
