Define Factorial method to Calculate Nitrogen Requirements?

The nitrogen requirements have been calculated by a factorial method suggested by different expert groups, described as follows:

R=U+F+S+G

Where R = N requirements,

U = loss of endogenous N in urine,

F = loss of endogenous N in faeces,

S = loss of N through skin, i.e., sweat and integumental losses, and

G = N required for growth.
