Effects of Weight Development, Pelting Time, Colour Type and Farm on Skin Length in Mink
The effects on skin length of pelting time, body weight in October/November and weight change until pelting were studied in four different colour types of young male mink on nine private farms. The skin length was closely related to body size, expressed either as body weight or as body length and condition (weight/length). The regression of skin length on body size differed between farms and colour types. Within the pelting season from mid November to mid December, the time of pelting did not affect the skin length of an average size mink, but the regression of skin length on body size interacted with the time of pelting. The effect of body weight on skin length was 11.8 cm kg-1 at the usual time of pelting and 14.5 cm kg-1 at pelting 16 days later. The effect on skin length of the weight in October/November was 12.6 cm kg-1, while the effect of a weight change between October/November and pelting was 5.5 cm kg-1.
