Popis:	Two lines of female farm mink were selected among the offspring of 495 mothers kept under conventional farm conditions. A low-stereotyping line ( n =146) arose from 75 non-stereotyping females and a high-stereotyping line ( n =150) was established from the 75 most stereotyping females. In two successive generations, the incidence of stereotypies was four times higher in the offspring of high-stereotyping females than in those of non-stereotyping females indicating a genetic transmission of the trait. Stereotypies were associated with higher fertility as revealed by fewer barren females, increased litter size, and lower mortality among the pups. Stereotyping females had lower body weight than non-stereotypers, and the association between stereotypies and fertility could exclusively be explained by reducing effects of stereotypies on body weight.
