ABSTRACT: The present study evaluates growth, fur properties, health condition and
reproduction performance in mink (Neovison
vison) and blue fox (Vulpes lagopus)
during growing-furring and reproduction periods. Diets compared were: Diet A,
which was composed of a high amount of slaughter-house offal but less fish
products than normal, and diet B, which was composed of low amounts of
slaughter-house offal but increased fish production content. Whelping succeeded
better in animals on diet B than on diet A. The difference in whelping result between
diets was 0.6 kits/mated female for mink (P i.e., 0.8 kits/mated
female. Calculated per whelped female, the difference was most pronounced in
mink (0.6 kits; P
