The study was aimed at an analysis of the effect that mating and whelping terms might have on the number of offspring of mink. Two primary reproduction-related traits were analysed: the number of born pups and the number of raised, or weaned, pups. More than 3600 litters were analysed over three years. The females were distributed into four groups depending on the date of mating, and into four other groups in respect to whelping date. The analysis of variance demonstrated a statistically significant effect of the date of the first mating, as well as the birth date of the offspring, on the number of born and raised pups. The highest mean numbers of born and raised pups was observed for the females mated within the first term (until 5 March). Minimally lower values were achieved by those mated within the third term, and slightly lower by those mated within the second term.
