Digestibility Trials with Moulting Mink

Digestibility trials with mink are traditionally conducted in periods with out moulting.

If conducted in a moulting period faeces is contaminated with hair, which is rich in nitrogen (N). Consequently, N- digestibility may be underestimated.

Knowing the magnitude of the theoretical error it is possible to define whether it is recommendable to per- form digestibility trials in the moulting periods or not.
