Crude protein

A measurement of protein content. In animal feeds, crude protein is calculated as mineral nitrogen x 6.25 (the assumption is that proteins of typical animal feeds contain 16% nitrogen in average). The mineral nitrogen value is obtained by the Kjeldahl method, or by a method giving similar results after correction, such as the Dumas method.
