This study aimed at answering the question whether production of new colour variants of American mink in mink farms using mutations may entail changes in skull morphology and relationships between the bone elements building it. Analyses were made on the skulls of 56 eight-month-old males and females of two American mink colour variants (standard Brown and mutant Sapphire) from the same farm. Mean values, standard deviations and coefficients of variation were determined for carcass weight, cranial and mandibular weights and 7 dorsal surface, 8 lateral surface and 11 basal surface traits of the skull. The values of 24 cranial and mandibular indices and the values of sexual size dimorphism (SSD), i.e. a coefficient describing differences between sexes, were...

This study aimed at presenting the values of 47 metric traits and 20 cranial indices of the skull of 291 mature farm chinchillas and comparing these data with those being determined on 32 chinchilla skull specimens from the Natural History Museum in London. Measurements of the viscerocranium, neurocranium and mandible parameters were taken. No normal distribution of these traits was observed. The values of selected Spearman's rank correlation coefficients were calculated. It was found that most cranial traits of the farm chinchillas showed statistically significantly higher values (P0.01) when compared to those being determined on the skulls of museum specimens. The effect of the farm environment, in which the farm chinchillas had been kept for many...
