The effects of drying (55 or 100 degreesC) on N content of feces, excreta,
and tissue when compared with wet materials were studied. Drying of excreta
but not feces or tissue, at 100 degreesC, resulted in significant N losses
(p < 0.01). Addition of HCl prior to drying at 55 degreesC reduced N losse
