Determination of Nitrogen and Protein in Feed

Nitrogen and Protein Determination in Feed Products according to the Kjeldahl Method
Determination of Nitrogen and Protein in Feed
An easy and reliable method for the determination of total nitrogen and protein in feed products according to the Kjeldahl method, as described in the ISO 5983-1:2005(E) and AOAC 954.01 regulations, is introduced below. The samples are digested using the SpeedDigester K-436 and K-439. The distillation and boric acid titration are performed with the Kjeldahl Sampler System K-370/K-371.
