The Effect of Protein Level on N-balance in Adult Mink (Mustela vison)

Basically the need for nitrogen is a require- ment for maintenance and a requirement de- pendent on a given production.
If the requirement for maintenance is known, it is possible to (g)estimate the total requirement for a given production.
The main purpose of the present experiment was to measure N-balance in adult male mink fed decreasing levels of protein with a constant amino acid profile.
