EVALUATION OF PASTEL FOX BREEDING RESULTS IN POLAND - REPRODUCTION

Andrzej Jakubczak

 

ABSTRACT



The evaluation of pastel fox breeding results was carried out through the estimation of selection differentials and genetic and phenotypic trends in some performance traits. The observations covered common fox females, reared during 1978-1997, from which a total of 4155 offspring were obtained with pastel colour of coat. The analysis of reproduction indices demonstrated that the average percentage of whelping females oscillated around 65.63%. The average number of born offspring ranged between 2.56 and 4.42 per a female of the herd.

Key words: pastel fox, selection differential, genetic trend.
