Diets formulated to contain similar chemical components but different caloric level were administered from July to December to minks of the same age and strain divided into 2 groups. During the first 2 months all animals received exactly the same feeding. From September 1, with monthly changes in the caloric intake level, controls received 19%, 15%, 8 % and 4% more calories than the experimental minks which were maintained at the same caloric feeding level from August to December. Results of the experiment indicated a feeding related clear biochemical topographical difference between tail and dorsal skin with decreased content of hexuronic ac. UA-GAG, Pro, Hyp, Hyl, water and fat (increased % DDS) in both locations under the restricted feeding. Reduction of fur quality was found in the reduced-feeding group. Results are discussed on the bases of importance of location and addition of new parameters for objective evaluation of skin quality, until today evaluated only subjectively.
