oa Agroanimalia - Modifications to the chromogen method as used in digestibility studies

Volume 1, Issue 2
  • ISSN : 0302-7104



Three modifications to simplify the chromogen method in routine analysis are descriptionbed. Homogenization of faecal samples can be reduced to one 7 min blending period by allowing the macerated faeces to soak in the solvent. The chromogen content of forages and faeces is calculated without basing it on a reference concentration of sodium chromate. The advantage of selecting a wavelength based on the absorption curve of the particular sample rather than calculating chromogen content at 406 mil is discussed.
