Extract

1. EUN and MFN excretions have been determined in goats on a N-low ration and also on a N-free ration. The values obtained were,

EUN = 0·052 g./kg. live weight and

MFN = 0·41 g./100 g. dry-matter feed intake.

2. The values so determined with the two feeding regimens, for both the EUN and MFN agreed very closely.

3. The minimum protein requirement of goats for maintenance, as calculated from the EUN value, is 0·65 lb./1000 lb. live weight.

4. The formula for calculating the utilizable protein requirement for this species is found to be P = 0·89. W0.734, and is almost identical with the one given by Mitchell.

5. The usefulness of the above formula in predicting the EUN of immature goats is discussed.
