ABSTRACT

The aim of this study was to determine factors, which significantly affect
pelt size and fur quality in arctic foxes, and to estimate genetic parameters
and breeding values for these traits. Data set consisted of 444 arctic foxes
of different colour types was analyzed. All animals were kept at one private
farm. The data were collected in 2004 – 2007. The studied traits were body
length, body circumference, body size and conformation, colour type, purity of
coat colour, coat quality and total score. GLM procedure and Duncan test were
used to test significance of differences between means. For all studied traits
heritabilities, genetic and phenotypic correlations and breeding values were
estimated. For this analysis, traits (graded on the discrete scale) were logistic
transformed using Ln function. Four different mixed models with different effects
were applied.

Key words: genetic parameters, pelt traits, body size, arctic fox.
