QUALITY ON AN ANNUAL CYCLE BASIS
Both mink and fox produce a litter once a year. Mink have a short mating period in March followed by a gestation period of approximately 52 days. The young are born between the end of April and beginning of May. The mating period of blue and silver foxes, the two common fox species, is a little more spread out, being from January to April. The gestation period for foxes lasts for 7 weeks.
After weaning, new breeding stock is selected before the month of November. Those animals that will not be kept for breeding will be left for harvesting during November/December. In order to prevent disease, the animals are vaccinated premises are cleaned and disinfected thoroughly, after which the cycle starts once again with the mating period.
